Spring可以对集合类型进行注入包括：Set集合，properties属性集合，Map集合以及List集合
注入方式如下：
package com.test; import java.util.ArrayList; import java.util.HashMap; import java.util.HashSet; import java.util.Map; import java.util.Properties; import java.util.Set; import java.util.List; public class UserServiceImplement implements IUserService { public Set<String> getS() { return s; } public void setS(Set<String> s) { this.s = s; } public Map<String, String> getM() { return m; } public void setM(Map<String, String> m) { this.m = m; } public Properties getP() { return p; } public void setP(Properties p) { this.p = p; } public List<String> getL() { return l; } public void setL(List<String> l) { this.l = l; } private Set<String> s = new HashSet<String>(); private Map<String, String> m = new HashMap<String, String>(); private Properties p = new Properties(); private List<String> l = new ArrayList<String>(); public void saveUser() { System.out.println("Set集合注入"); for (String str : s) { System.out.println(str); } System.out.println("------------------------------"); System.out.println("Map集合注入"); for (String str : m.values()) { System.out.println(str); } System.out.println("------------------------------"); System.out.println("Properties属性集合注入"); for (Object str : p.values()) { System.out.println(str); } System.out.println("------------------------------"); System.out.println("List集合注入"); for (String str : l) { System.out.println(str); } } }要注意的是：这些集合属性也必须要有对应的setter方法
