'delete' 不支持 spring 启动

Question

使用 Angular 8 和 Springboot 应用程序...通过 JSON 传递值时出现错误：不支持请求删除这是错误：

This application has no explicit mapping for /error, so you are seeing this as a fallback.

Thu Dec 05 22:55:04 WET 2019 There was an unexpected error (type=Method Not Allowed, status=405). Request method 'GET' not supported

 @DeleteMapping("/Emp/{id}")
        public boolean deleteEmployee(@PathVariable Long id) {
         collaborateurRepository.deleteById(id);
            return true;
        }

Component.ts

 deleteEmployee() {
    this.employeservice.deleteEmployee(this.employee.id)
      .subscribe(data => console.log(data), error => console.log(error));

    this.gotoList();
  }

服务：

 deleteEmployee( id: number): Observable<Object> {
      return this.http.delete(`http://localhost:8080/api/Emp/`+id);
    }

Answer 1

您似乎正在调用 REST-Api 来删除带有 HTTP-GET 请求的条目。您必须使用 HTTP-DELETE 调用此端点，这将防止 Method not allowed 错误。假设您的 UI 有一个像 get(/Emp/123) 这样的电话，应该是 delete(/Emp/123).

Answer 2

我找到了答案，除了删除方法之外，我还必须添加获取方法谢谢你们:)

 @RequestMapping(value="/empdelete/{id}", method= {RequestMethod.DELETE, RequestMethod.GET})
 public boolean deleteEmployee( @PathVariable("id") Long id) {
     collaborateurRepository.deleteById(id);
        return true;
    }
