spring-注入list集合对象（值是对象）

科技2025-05-01 10

1.创建stu类

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; private List<Course> courseList; public void setCourseList(List<Course> courseList) { this.courseList = courseList; } // 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.创建Course类

public class Course { private String cname; public void setCname(String cname) { this.cname = cname; } }

3.配置bean1.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" 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">                              <property name="courseList"> <list> <ref bean="course1"></ref> <ref bean="course2"></ref> </list> </property> </bean>  <bean id="course1" class="com.spring.collections.Course"> <property name="cname" value="Spring5"></property> </bean> <bean id="course2" class="com.spring.collections.Course"> <property name="cname" value="MyBatis"></property> </bean> </beans>
