1.创建Stu类
package com.spring.collections; import java.util.Arrays; import java.util.List; import java.util.Map; import java.util.Set; public class Stu { //1.数组类型 private String[] courses; //2.list集合属性 private List<String> list; //3.map集合类型 private Map<String,String> map; //4.set集合属性类型 private Set<String> set; public void setSet(Set<String> set) { this.set = set; } public void setMap(Map<String, String> map) { this.map = map; } public void setList(List<String> list) { this.list = list; } public void setCourses(String[] courses) { this.courses = courses; } public void test(){ System.out.println(Arrays.toString(courses)); System.out.println(list); System.out.println(map); System.out.println(set); } }2.bean1.xml的注入配置
<?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"> <bean name="stu" class="com.spring.collections.Stu"> <!--数组类型的注入--> <property name="courses"> <array> <!--array表示数组注入形式--> <value>Struts框架</value> <value>Spring框架</value> </array> </property> <!--list类型的注入--> <property name="list"> <list> <value>mybatis框架</value> <value>Spring MVC</value> </list> </property> <!--map类型的注入--> <property name="map"> <map> <entry key="JAVA" value="java"></entry> <entry key="SSM" value="ssm"></entry> </map> </property> <!--set类型注入--> <property name="set"> <set> <value>kevin</value> <value>Ron</value> </set> </property> </bean> </beans>3.创建测试类进行测试
package com.spring.test; import com.spring.collections.Stu; import org.junit.Test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class TestSpringDemo1 { @Test public void testCollection(){ //加载bean1.xml文件 ApplicationContext applicationContext=new ClassPathXmlApplicationContext("bean1.xml"); //获取配置对象 Stu stu = applicationContext.getBean("stu", Stu.class); stu.test();//调用方法 } }
