@PostMapping("/addCourse") @ResponseBody public AjaxResult addCourse(Course course){ AjaxResult ajaxResult = new AjaxResult(); try { int count = courseService.addCourse(course); if(count > 0){ ajaxResult.setSuccess(true); ajaxResult.setMessage("添加成功"); }else{ ajaxResult.setSuccess(false); ajaxResult.setMessage("添加失败"); } }catch (Exception e){ e.printStackTrace(); ajaxResult.setSuccess(false); ajaxResult.setMessage("添加失败"); } return ajaxResult; } 对他写Junit单元测试

可以使用JUnit和Mockito来编写单元测试。首先，需要在pom.xml文件中添加JUnit和Mockito的依赖：

<!-- JUnit -->
<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    <scope>test</scope>
</dependency>

<!-- Mockito -->
<dependency>
    <groupId>org.mockito</groupId>
    <artifactId>mockito-core</artifactId>
    <version>3.9.0</version>
    <scope>test</scope>
</dependency>

然后，编写单元测试代码：

@RunWith(MockitoJUnitRunner.class)
public class CourseControllerTest {

    @InjectMocks
    private CourseController courseController;

    @Mock
    private CourseService courseService;

    @Test
    public void testAddCourse() {
        Course course = new Course();
        // 设置course的属性

        when(courseService.addCourse(course)).thenReturn(1);

        AjaxResult ajaxResult = courseController.addCourse(course);

        assertTrue(ajaxResult.isSuccess());
        assertEquals("添加成功", ajaxResult.getMessage());
    }
}

在这个测试中，使用Mockito来模拟CourseService的addCourse方法的返回值，然后调用CourseController的addCourse方法，并验证返回的AjaxResult对象的属性是否符合预期。
