java - Spring:发布请求未到达 Controller 类

Question

我正在开发我的第一个基于 spring 的示例项目。以下是我的dispatcher-servlet.xml 的摘录。

<mvc:view-controller path="" view-name="test" />
<!-- location to scan for controllers -->
<context:component-scan base-package="com.test.demo.student.controller" />

我尝试向以下网址发送帖子，但它似乎从未到达相应的 Controller 类:

网址:http://localhost:8080/TestProject/student/retrieveDetails

@Controller
@RequestMapping("student")
public class StudentController {

private final Logger logger = Logger.getLogger(StudentController.class);

@Autowired
public StudentService studentService;

public void setStudentService(StudentService studentService) {
    this.studentService = studentService;
}


 @RequestMapping(value = "/retrieveDetails", method = RequestMethod.POST)
public @ResponseBody String retrieveDetails(@RequestBody RetrieveStudentRequestBo retrieveStudentRequestBo,HttpServletRequest req,HttpServletResponse res) {

    logger.info("Entering StudentController.retrieveDetails()" );

帖子输入{"testID":"1"}

ERROR [400]
Bad Request 

是响应。

虽然一切似乎都已就位，但为什么我收到 400 错误？

Answer 1

请在学生前添加斜杠:

@Controller
@RequestMapping("/student")
public class StudentController {
...
}

此外，我希望您的构建工件将是 TestProject.war，因为这是您路径的一部分。
