spring的数组 list set map

使用的是set注入：

package com.chen;import java.util.*;public class Stu {//1.数组类型private String[] courses;//2.list集合类型属性private List<String> list;//3.map集合类型属性Map<String,Object> map;//4.set集合类型的 属性private Set<String> set;public List<Course> courseList;public void setCourseList(List<Course> courseList) {this.courseList = courseList;}public void setCourses(String[] courses) {this.courses = courses;}public void setList(List<String> list) {this.list = list;}public void setMap(Map<String, Object> map) {this.map = map;}public void setSet(Set<String> set) {this.set = set;}public void show(){for (String cours : courses) {System.out.println("数组==》"+cours);}for (String s : list) {System.out.println("list==>"+s);}for (String s : set) {System.out.println("set==>"+s);}Set<String> set = map.keySet();Iterator<String> iterator = set.iterator();while (iterator.hasNext()){Object next = iterator.next();Object o = map.get(next);System.out.println(next+":"+o);}for (Course course : courseList) {System.out.println("courseList==>"+course);}}}

这是xml配置，里面分别展示了几种类型的value值的写法
