springmvc 添加Junit4

junit 单元测试的好处我就不赘述了，本文旨在介绍自己使用的一个方式：

1.添加依赖

<dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.7</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.mockito</groupId>
            <artifactId>mockito-core</artifactId>
            <version>1.9.5</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>3.1.0.RELEASE</version>
            <scope>test</scope>
        </dependency>

2.在工程目录下创建test source folder

3.创建Junit TestCase

在包路径上面单击右键：new-->other-->　Junit Test Case

4.添加

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
    "file:src/main/webapp/WEB-INF/spring/root-context.xml"
})  

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
    "file:src/main/webapp/WEB-INF/spring/root-context.xml"
})
public class TestSpring{
    @Autowired
    private ApplicationContext applicationContext;
    @Autowired
    private HomeService homeService;

    @Test
    public void test() {

        Object bean = applicationContext.getBean("mysqlDataSource");

        System.out.println("========================="+bean);

        try {
            homeService.updateAgeNonException();
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}
