JunitTest.java

package com.dqiang;

public interface JunitTest {
    public String sayHelloWorld(String word);
}

package com.dqiang;
public interface JunitTest {

public String sayHelloWorld(String word);

}

JunitTestImpl.java

package com.dqiang.impl;

import org.springframework.stereotype.Service;

import com.dqiang.JunitTest;

@Service
public class JunitTestImpl implements JunitTest {
    public String sayHelloWorld(String word) {
        return "hello->" + word;
    }
}

package com.dqiang.impl;
import org.springframework.stereotype.Service;
import com.dqiang.JunitTest;
@Service

public class JunitTestImpl implements JunitTest {

public String sayHelloWorld(String word) {

return "hello->" + word;

}

}

JTest.java

package springJunit;

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.dqiang.JunitTest;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:springmvc.xml" })
public class JTest {
    @Autowired
    private JunitTest junitTest;

    @Test
    public void sayHelloWorld() {
        String result = junitTest.sayHelloWorld("junit Test");
        System.out.println(result);
    }
}

package springJunit;
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.dqiang.JunitTest;
@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration(locations = { "classpath:springmvc.xml" })

public class JTest {

@Autowired

private JunitTest junitTest;
@Test
public void sayHelloWorld() {
	String result = junitTest.sayHelloWorld("junit Test");
	System.out.println(result);
}

}

说明：

@RunWith 使用RunWith注解改变JUnit的默认执行类，并实现自已的Listener在平时的单元测试，如果不使用RunWith注解，那么JUnit将会采用默认的执行类Suite执行。
@ContextConfiguration 可以通过该属性手工指定 Spring 配置文件所在的位置，可以指定一个或多个 Spring 配置文件。
