使用springJunit的简单实例：

springJUnit4的使用并没有想象中的那么难，写了一个hello world程序，废话不多说，先上代码：

package spring.shusheng.service;

public interface HelloService {

    public String sayHello(String str) ;
}

package spring.shusheng.service.impl;

import org.springframework.stereotype.Component;
import spring.shusheng.service.HelloService;

@Component
public class HelloServiceImpl implements HelloService {

    @Override
    public String sayHello(String str ) {

        return "hello "+ str;
    }


}

package test;

import javax.annotation.Resource;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import spring.shusheng.service.HelloService;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:META-INF/applicationContext.xml")
public class HelloServiceTest {

    private HelloService helloService;

    @Test
    public void testSayHello() {
        System.out.println(helloService.sayHello("world"));
    }

    @Resource
    public void setHelloService(HelloService helloService) {
        this.helloService = helloService;
    }

}

下面是applicationContext.xml的配置内容：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

<context:component-scan base-package="spring.shusheng.service" />

</beans>

下面是web.xml的配置内容：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:META-INF/applicationContext.xml</param-value>
  </context-param>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
</web-app>

下面是整个工程文件的结构和相应的jar包

运行后自己看结果总结吧。
