【使用篇二】SpringBoot单元测试（10）

SpringCloud单元测试：https://www.cnblogs.com/myitnews/p/11796321.html

1. 创建项目Maven Project，修改pom.xml

<properties>
    <java.version>1.8</java.version>
</properties>
 
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <!-- 添加 junit 环境的 jar 包 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
    </dependency>
</dependencies>

2. 编写业务逻辑

(1) 持久层

@Repository
public class UserDaoImpl {
 
    public void insertUser(){
        System.out.println("insert into user....dao");
    }
 
}

(2)业务层

@Service
public class UserServiceImpl {
 
    @Autowired
    private UserDaoImpl userDaoImpl;
 
    public void saveUser(){
        System.out.println("save user ... service");
        userDaoImpl.insertUser();
    }
}

3. 编写启动类

@SpringBootApplication
public class App {
 
    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
 
}

4. 编写测试类

在src/test/java下创建测试类

/**
 * @RunWith:启动器
 * SpringJUnit4ClassRunner.class：让 junit 与 spring 环境进行整合
 *
 * @SpringBootTest(classes={App.class})
 * 1,当前类为 springBoot 的测试类
 * 2,加载 SpringBoot启动类，启动 springBoot
 *
 * junit 与 spring 整合
 * @Contextconfiguartion("classpath:applicationContext.xml")
 */
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes={App.class})
public class UserServiceTest {
 
    @Autowired
    private UserServiceImpl userServiceImpl;
 
    @Test
    public void testService(){
        userServiceImpl.saveUser();
    }
}
