我正在使用Spring Boot和MongoDB构建一个Web应用程序，它将仅对员工文档执行CRUD操作。
"Request method 'POST' not supported"当我尝试使用json命中create employee端点时出现此错误。
"Request method 'POST' not supported"
我的控制器类是：
@RestController @RequestMapping("/employeeapp/employees") public class EmployeeController { private final EmployeeService service; @Autowired public EmployeeController(EmployeeService service) { this.service = service; } @RequestMapping(method = RequestMethod.POST) @ResponseStatus(HttpStatus.CREATED) public @ResponseBody Employee create(@RequestBody @Valid Employee employeeEntry) { return service.create(employeeEntry); } @RequestMapping(value = "{id}", method = RequestMethod.DELETE) public Employee delete(@PathVariable("id") long id) { return service.delete(id); } @RequestMapping(method = RequestMethod.GET) public List<Employee> findAll() { return service.findAll(); } @RequestMapping(value = "{id}", method = RequestMethod.GET) public Employee findById(@PathVariable("id") long id) { return service.findById(id); } @RequestMapping(value = "{id}", method = RequestMethod.PUT) public Employee update(@RequestBody @Valid Employee employeeEntry) { return service.update(employeeEntry); } @ExceptionHandler @ResponseStatus(HttpStatus.NOT_FOUND) public void handleEmployeeNotFound(EmployeeNotFoundException exception) { } }
应用类别：
@SpringBootApplication public class Application { public static void main(String[] args) throws Exception { SpringApplication.run(Application.class, args); } }
我尝试禁用csrf，添加@ResponseBody了方法，但似乎没有任何效果。
csrf
@ResponseBody

我遇到http://localhost:8080/employeeapp/employees了POST请求。标题包含Content-Type : application/json，并在正文中包含以下json：
http://localhost:8080/employeeapp/employees
Content-Type : application/json
{ "id" : 1, "name" : "nikhil", "dept" : "DCX" }
另外，这是我通过POST请求点击上述URL时在日志中看到的内容。

我检查了Spring引导日志，结果是未生成映射，而是spring映射到默认服务。知道为什么会发生吗？
