Spring集成Junit

1.导入Spring集成Junit的坐标

在pom.xml中添加依赖

<dependency>
    <groupId>org.springframeworkgroupId>
    <artifactId>spring-testartifactId>
    <version>5.0.5.RELEASEversion>
dependency>

2.使用@Runwith注解替换原来的运行期

@RunWith(SpringJUnit4ClassRunner.class)

3.@ContextConfiguration指定配置文件或配置类

导入配置文件
格式：@ContextConfiguration(“classpath:配置文件名”)

@ContextConfiguration("classpath:applicationContext.xml")//导入xml配置文件

导入配置类
格式：@ContextConfiguration(classes = {类名1.class，类名2.class})

@ContextConfiguration(classes = {SpringConfiguration.class})

4.使用@Autowired注入需要测试的对象

   //导入测试对象
    @Autowired
    private UserService userService;

    @Autowired
    private DataSource dataSource;

5.创建测试方法进行测试

@Test
public void test() throws SQLException {
    userService.save();
    System.out.println(dataSource.getConnection());
}

6.完整代码

@RunWith(SpringJUnit4ClassRunner.class)
//@ContextConfiguration("classpath:applicationContext.xml")//导入xml配置文件
@ContextConfiguration(classes = {SpringConfiguration.class})//导入配置类
public class SpringJunitTest {
    //导入测试对象
    @Autowired
    private UserService userService;

    @Autowired
    private DataSource dataSource;

    //测试方法
    @Test
    public void test() throws SQLException {
        userService.save();
        System.out.println(dataSource.getConnection());
    }
}
