前言

第一次入手ssm框架，想把这些框架整合需要的步骤全部记录下来，既是为了以后回顾，也是为了重新巩固一遍知识，虽然还不是很懂各种各样的配置，但是还是要去慢慢理解，因而此举很有必要，下面我们进入ssm框架的整合吧。

一、SSM框架中各层级间的作用及关系？

表现层（springMVC）：Controller层（Handler层） 负责具体的业务模块流程的控制

Controller层通过要调用Service层的接口来控制业务流程，控制的 配置也在Spring配置文件里面。

业务层（Spring）：Service层 Service层：负责业务模块的逻辑应用设计。 首先设计其接口，然后再实现他的实现类。 通过对Spring配置文件中配置其实现的关联，完成此步工作，我们 就可以通过调用Service的接口来进行业务处理。 最后通过调用DAO层已定义的接口，去实现Service具体的 实现类。

持久层（Mybatis）：Dao层（Mapper层） Dao层：负责与数据库进行交互设计，用来处理数据的持久化工作。 DAO层的设计首先是设计DAO的接口， 然后在Spring的配置文件中定义此接口的实现类，就可在其他模块中 调用此接口来进行数据业务的处理，而不用关心接口的具体实现类是 哪个类，这里用到的就是反射机制， DAO层的数据源配置，以及有 关数据库连接的参数都在Spring的配置文件中进行配置。

视图层：View层 负责前台jsp页面的展示。 此层需要与Controller层结合起来开发。

各层次之间的联系 本来Controller层与View层是可以放在.jsp文件里一起开发的，但是为了降低代码的复杂度，提高其可维护性，将其分为了这两层，这也体现了MVC框架的特性，即结构清晰，耦合度低。 Service层是建立在DAO层之上的，建立了DAO层后才可以建立Service层，而Service层又是在Controller层之下的，因而Service层应该既调用DAO层的接口，又要提供接口给Controller层的类来进行调用，它刚好处于一个中间层的位置。每个模型都有一个Service接口，每个接口分别封装各自的业务处理方法。

二、使用步骤

1.设计数据库，建表

create table account ( id int auto_increment primary key, username varchar(255) not null, money int(255) not null );

2.导入相关依赖

<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>org.example</groupId> <artifactId>ssmP</artifactId> <version>1.0-SNAPSHOT</version> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <spring.version>4.3.14.RELEASE</spring.version> </properties> <dependencies> <!-- JSTL，2个 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <dependency> <groupId>taglibs</groupId> <artifactId>standard</artifactId> <version>1.1.2</version> </dependency> <!-- 数据库部分 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>8.0.12</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.4.6</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.2</version> </dependency> <!-- 连接池 --> <!-- https://mvnrepository.com/artifact/com.alibaba/druid --> <dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.5.2</version> </dependency> <!-- spring系列 --> <!-- https://mvnrepository.com/artifact/org.springframework/spring-context --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <!-- 日志记录 --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <!-- tomcat环境，2个 --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope><!-- 容器提供的包，不需要打包 --> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>javax.servlet.jsp-api</artifactId> <version>2.3.1</version> <scope>provided</scope> </dependency> </dependencies> <!--资源过滤问题--> <build> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> </includes> <filtering>false</filtering> </resource> <resource> <directory>src/main/resources</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> </includes> <filtering>false</filtering> </resource> </resources> </build> </project>

3.相关配置文件

db.properties

jdbc.driverClass=com.mysql.cj.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/sqlfiftypractice?useSSL=false&useUnicode=true&characterEncoding=UTF-8&serverTimezone=GMT%2B8 jdbc.username=root jdbc.password=123456

log4j.properties

log4j.rootLogger = INFO , stdout log4j.logger.mypackage=DEBUG log4j.appender.stdout = org.apache.log4j.ConsoleAppender log4j.appender.stdout.Target = System.out log4j.appender.stdout.layout = org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern = %d{yyyy-MM-dd HH:mm:ss} [%t] %-5p %c{1}:%L - %m%n

web.xml配置文件

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" version="4.0"> <!--DispatcherServlet--> <servlet> <servlet-name>DispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <!--一定要注意:我们这里加载的是总的配置文件，之前被这里坑了！--> <param-value>classpath:application-context.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>DispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!--encodingFilter--> <filter> <filter-name>encodingFilter</filter-name> <filter-class> org.springframework.web.filter.CharacterEncodingFilter </filter-class> <init-param> <param-name>encoding</param-name> <param-value>utf-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!--Session过期时间--> <session-config> <session-timeout>15</session-timeout> </session-config> </web-app>

4.框架核心配置文件

spring-dao.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <context:annotation-config/> <!--1.配置数据库相关参数 --> <context:property-placeholder location="classpath:db.properties"/> <!--2.数据库连接池--> <bean name="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <!--配置连接池属性--> <property name="driverClass" value="${jdbc.driverClass}"/> <!-- 基本属性 url、user、password --> <property name="jdbcUrl" value="${jdbc.url}" /> <property name="user" value="${jdbc.username}"/> <property name="password" value="${jdbc.password}" /> </bean> <!--约定大于配置--> <!--3.配置SqlSessionFactory对象--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!--往下才是mybatis和spring真正整合的配置--> <!--注入数据库连接池--> <property name="dataSource" ref="dataSource"/> <!--配置mybatis全局配置文件:mybatisConfig.xml--> <property name="configLocation" value="classpath:mybatis-config.xml"/> <!--扫描entity包,使用别名,多个用;隔开--> <property name="typeAliasesPackage" value="com.lhh.pojo"/> <!--扫描sql配置文件:mapper需要的xml文件--> <!--<property name="mapperLocations" value="classpath:config/mybatis/*Mapper.xml"/>--> </bean> <bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate"> <constructor-arg index="0" ref="sqlSessionFactory" /> </bean> <!-- 4:配置扫描Dao接口包,动态实现DAO接口,注入到spring容器--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!--注入SqlSessionFactory--> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/> <!-- 给出需要扫描的Dao接口--> <property name="basePackage" value="com.lhh.dao"/> </bean> </beans>

spring-service.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!--扫描service包下所有使用注解的类型--> <context:component-scan base-package="com.lhh.service"/> <!--配置事务管理器--> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!--注入数据库连接池--> <property name="dataSource" ref="dataSource"/> </bean> <!--配置基于注解的声明式事务默认使用注解来管理事务行为--> <tx:annotation-driven transaction-manager="transactionManager"/> </beans>

spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <!--配置spring mvc--> <!--1,开启springmvc注解模式 a.自动注册DefaultAnnotationHandlerMapping,AnnotationMethodHandlerAdapter b.默认提供一系列的功能:数据绑定，数字和日期的format@NumberFormat,@DateTimeFormat c:xml,json的默认读写支持--> <mvc:annotation-driven/> <!--2.静态资源默认servlet配置--> <!-- 1).加入对静态资源处理：js,gif,png 2).允许使用 "/" 做整体映射 --> <mvc:default-servlet-handler/> <!--3：配置JSP 显示ViewResolver--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/> <property name="prefix" value="/WEB-INF/jsp/"/> <property name="suffix" value=".jsp"/> </bean> <!--4:扫描web相关的bean--> <context:component-scan base-package="com.lhh.controller"/> </beans>

mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <!--<settings> &lt;!&ndash;<setting name="logImpl" value="STDOUT_LOGGING"/>&ndash;&gt; &lt;!&ndash;<setting name="logImpl" value="LOG4J"/>&ndash;&gt; </settings>--> <typeAliases> <!--给全限定类名起一个别名，在映射文件中使用这个别名，节省了开发的时间--> <typeAlias type="com.lhh.pojo.Account" alias="account"></typeAlias> </typeAliases> <mappers> <!--在同一个包下，并且名称相同可以使用.--> <mapper class="com.lhh.dao.AccountMapper"></mapper> </mappers> </configuration>

spring核心配置文件:application-context.xml(把前面的三个层的配置文件导入到该配置文件当中)

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <import resource="spring-dao.xml"></import> <import resource="spring-service.xml"></import> <import resource="spring-mvc.xml"></import> </beans>

5.编写mapper（dao层）

package com.lhh.dao; import com.lhh.pojo.Account; import org.apache.ibatis.annotations.Param; import org.omg.CORBA.PUBLIC_MEMBER; import org.springframework.stereotype.Repository; import java.util.List; @Repository public interface AccountMapper { public int addAccount(Account account); public int deleteAccount(@Param("id") int id); public int updateAccoount(Account account); public List<Account> queryAccount(); public Account queryAccountById(@Param("id") int id); public List<Account> queryAccountByName(String name); }

6.定义跟mapper同包同名的配置文件

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <!--namespace制定对应的mapper--> <mapper namespace="com.lhh.dao.AccountMapper"> <!--插入用户--> <insert id="addAccount" parameterType="account"> insert into account(username,money) values(#{username},#{money}) </insert> <!--删除用户--> <delete id="deleteAccount" parameterType="int"> delete from account <where> <if test="id != null"> id=#{id} </if> </where> </delete> <!--查询用户--> <select id="queryAccount" resultType="account"> select * from account </select> <!--根据id进行查询--> <select id="queryAccountById" resultType="account" parameterType="int"> select * from account <where> <if test="id != null"> id=#{id} </if> </where> </select> <!--更新--> <update id="updateAccoount" parameterType="account"> update account <set> <if test="username != null"> username=#{username}, </if> <if test="money != null"> money=#{money} </if> </set> where id=#{id} </update> <!--根据用户名称进行查询--> <select id="queryAccountByName" parameterType="String" resultType="account"> select * from account where username like #{name} </select> </mapper>

7.编写pojo层（entity，model)

有一个lombok插件，可以自动生成set，get，以及构造方法，但是不建议使用。

package com.lhh.pojo; public class Account { private int id; private String username; private int money; public Account(int id, String username, int money) { this.id = id; this.username = username; this.money = money; } @Override public String toString() { return "Account{" + "id=" + id + ", username='" + username + '\'' + ", money=" + money + '}'; } public Account() { } public int getId() { return id; } public void setId(int id) { this.id = id; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public int getMoney() { return money; } public void setMoney(int money) { this.money = money; } }

8.编写service层

package com.lhh.service; import com.lhh.pojo.Account; import org.apache.ibatis.annotations.Param; import java.util.List; public interface UserService { public int addAccount(Account account); public int deleteAccount(int id); public int updateAccoount(Account account); public List<Account> queryAccount(); public Account queryAccountById(int id); public List<Account> queryAccountByName(String name); }

service接口的实现类:

package com.lhh.service.impl; import com.lhh.dao.AccountMapper; import com.lhh.pojo.Account; import com.lhh.service.UserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.stereotype.Service; import java.util.List; @Service public class UserServiceImpl implements UserService { /*注入dao*/ @Autowired private AccountMapper accountMapper; public int addAccount(Account account) { return accountMapper.addAccount(account); } public int deleteAccount(int id) { return accountMapper.deleteAccount(id); } public int updateAccoount(Account account) { return accountMapper.updateAccoount(account); } public List<Account> queryAccount() { return accountMapper.queryAccount(); } public Account queryAccountById(int id) { return accountMapper.queryAccountById(id); } public List<Account> queryAccountByName(String name) { return accountMapper.queryAccountByName(name); } }

9.编写controller层

package com.lhh.controller; import com.lhh.pojo.Account; import com.lhh.service.UserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; import javax.servlet.http.HttpServletRequest; import java.util.List; @Controller @RequestMapping("/account") public class AccountController { @Autowired @Qualifier("userServiceImpl") private UserService userService; @RequestMapping("/queryAllAccount") private String test1(HttpServletRequest request, Model model) { List<Account> accounts = userService.queryAccount(); model.addAttribute("list", accounts); return "allAccount"; } @RequestMapping("/showAllAccount") private String showAllAccount(HttpServletRequest request, Model model) { List<Account> accounts = userService.queryAccount(); model.addAttribute("list", accounts); return "allAccount"; } @RequestMapping("/toUpdateAccount") private String toUpdateAccount(int id, Model model) { Account account = userService.queryAccountById(id); model.addAttribute("account", account); return "updateAccount"; } @RequestMapping("/updateAccount") private String updateAccount(Account account, Model model) { System.out.println(account); int i = userService.updateAccoount(account); /*Account account1 = userService.queryAccountById(account.getId()); model.addAttribute("account",account1);*/ return "redirect:/account/queryAllAccount"; } @RequestMapping("/del/{accountId}") private String del(@PathVariable("accountId") int id) { int i = userService.deleteAccount(id); return "redirect:/account/queryAllAccount"; } @RequestMapping("/toAddAccount") private String toAddAccount() { return "addAccount"; } @RequestMapping("/addAccount") private String AddAccount(Account account) { System.out.println(account); int i = userService.addAccount(account); System.out.println("i=" + i); return "redirect:/account/queryAllAccount"; } @RequestMapping("/search") private String search(String name, Model model) { System.out.println(name); if (name == null || name == "") { /*给出一个提示:*/ model.addAttribute("error", "没有查询到数据"); } List<Account> accounts = userService.queryAccountByName("%" + name + "%"); if (accounts == null) { //没有查询到该条数据 /*显示全部数据*/ accounts = userService.queryAccount(); } model.addAttribute("list", accounts); return "allAccount"; } }

10.前端页面

总结

ssm框架整合其实刚开始还是挺难得，要坚持下来，多去看看，尤其是那些配置文件，具体是要怎么配置，以及配置文件与配置文件之间的关系。花点时间多理解一下里面的每一个标签具体起了什么作用，理解一点，虽然有很多东西都是固定好的，不用改动。还有一点就是学习框架，就是要自己多动手写代码，这算是我的第一个ssm框架项目，期间遇到了很多很多的问题，不过最终都得到了解决。当然这只算是一个很简单的入门，知道了业务是要怎么写的，但是对于真正掌握还是有很长一段路要走的。加油在controller和前端页面之间花了挺多时间的，不过相比与以前还是轻松了不少。继续加油，多写写，可能成就感就出来了。
