Question

spring怎样注入集合，list，set，map各怎样注入

Answer 1

package com.spring.test.springSession.service;

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

public class AOPService {

	private Map<String ,Object>  exampleMap  ;
	
	private List<Object> exampleList ;
	
	private Set<Object>  exampleSet  ;
	
	public Map<String, Object> getExampleMap() {
		return exampleMap;
	}

	public void setExampleMap(Map<String, Object> exampleMap) {
		this.exampleMap = exampleMap;
	}

	public List<Object> getExampleList() {
		return exampleList;
	}

	public void setExampleList(List<Object> exampleList) {
		this.exampleList = exampleList;
	}

	public Set<Object> getExampleSet() {
		return exampleSet;
	}

	public void setExampleSet(Set<Object> exampleSet) {
		this.exampleSet = exampleSet;
	}
	
	public String AopSercieMethod(){
		System.out.println("exampleList  :"+exampleList);
		System.out.println("exampleMap  :"+exampleMap);
		System.out.println("exampleSet  :"+exampleSet);
		return "这是xx的Spring-Session测试";
	}
}

以上是等待被注入的类

下面是配置类

package com.spring.test.springSession.config;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.HashSet;
import java.util.List;
import java.util.Map;
import java.util.Set;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.spring.test.springSession.aop.AOPAspect;
import com.spring.test.springSession.service.AOPService;

@Configuration
public class AOPConfig {

	@Bean
	public AOPService getAopService(){
		AOPService aopService = new AOPService();
		List<Object> exampleList = new ArrayList<Object>();
		exampleList.add("我是一个list注入属性");
		Set<Object> exampleSet = new HashSet<Object>();
		exampleSet.add("我是一个set注入属性");
		Map<String,Object> exampleMap = new HashMap<String,Object>();
		exampleMap.put("你好", "我是一个Map注入");
		aopService.setExampleList(exampleList);
		aopService.setExampleSet(exampleSet);
		return aopService;
	}
}

然后是配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:util="http://www.springframework.org/schema/util"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/util 
        http://www.springframework.org/schema/util/spring-util.xsd">

	<context:annotation-config />

	<bean class="com.spring.test.springSession.config.AOPConfig"/>
	
</beans>

然后是测试类

package com.spring.test.springSession.test;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.spring.test.springSession.service.AOPService;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath*:**/spring.xml"})
public class InjectTest {
	
	@Autowired
	AOPService aopService ;
	
	@Test
	public void test(){
		aopService.AopSercieMethod();
	}

}

然后结果

Answer 2

<bean class="java.util.ArrayList" id="mylise"/>
