【junit】SpringBoot集成junit测试

引入依赖

<!--        可以省略get set方法-->
<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
</dependency>

    <groupId>junit</groupId>
    <artifactId>junit</artifactId>

测试类

boot项目会有一个test目录，下面这个类可以用于单元测试

上代码！

// 用到自动注入的话，需要添加注解：@RunWith(SpringRunner.class)
