javascript - Spring Boot不支持“删除”

Question

使用 Angular 8 和 Springboot 应用程序...通过 JSON 传递值出现错误: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;
        }

组件.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

看起来您正在调用 REST-Api 来通过 HTTP-GET 请求删除条目。您必须使用 HTTP-DELETE 调用此端点，这将防止出现“方法不允许”错误。假设您的 UI 有一个类似 get(/Emp/123) 的调用，它应该是 delete(/Emp/123)。
