spring集合注入

集合注入方式如下：

package com.dp.service;

import java.util.List;
import java.util.Map;
import java.util.Properties;
import java.util.Set;

public class UnionService {

	public List<String> list;

	public Map<String, String> map;

	public Set<String> set;

	public Properties prop;

	public void setProp(Properties prop) {
		this.prop = prop;
	}

	public void setList(List<String> list) {
		this.list = list;
	}

	public void setMap(Map<String, String> map) {
		this.map = map;
	}

	public void setSet(Set<String> set) {
		this.set = set;
	}

	public void unionDITest(){
		//list
		System.out.println("list DI result：");
		for(String strlist:list){
			System.out.println(strlist);
		}
		//set
		System.out.println("set DI result：");
		for(String strset:set){
			System.out.println(strset);
		}
		//map
		System.out.println("map DI result：");
		for(String strMap:map.keySet()){
			System.out.println(strMap + " = " +map.get(strMap));
		}
		//prop
		System.out.println("prop DI result: ");
		for(Object strProp:prop.keySet()){
			System.out.println(strProp + " = " + prop.getProperty((String) strProp));
		}

	}

}
