Question

我目前正在使用angularJS作为我的前端，我正在通过REST调用spring MVC来删除多个对象

在我的角度函数中，我有一个将返回的方法 “本地主机：9000 / API /部门/ deleteSelectedDepartments / 1517,1518”

   deleteSelectedDepartments(selectedDepartments: any): Observable<ResponseWrapper> {

    var id = "";
    var index = 0;

    for(const key in selectedDepartments) {
        if(index == (Object.keys(selectedDepartments).length - 1)) {
            id += key;
        } else {

            id += key;
            id += ",";
        }
        index++;
    }

    return this.http.delete(`${this.resourceDeleteDepartmentsUrl}/${id}`);
}

1517和1518表示部门ID。

但是，我在Spring MVC中收到错误，我不完全确定如何正确接收该对象。

目前在我的DepartmentResource.java（spring mvc）

中

@DeleteMapping("/departments/deleteSelectedDepartments/{ids}")
@Timed
public ResponseEntity<Void> deleteSelectedDepartments(@PathVariable String ids) {
    log.debug("REST request to delete Department : {}", ids);
    return ResponseEntity.ok().headers(HeaderUtil.createEntityDeletionAlert(ENTITY_NAME, "blank")).build();
}

我收到的错误消息是找不到错误404。

DELETE http://localhost:9000/api/departments/deleteSelectedDepartments/1589,1590 404 (Not Found)

如果有更好的办法，请指教！谢谢！

您的映射是错误的。你所拥有的不是请求参数（URL将是/api/departments/deleteSelectedDepartments?departmentIds=1517,1518）。

你有什么路径变量：

@DeleteMapping("/departments/deleteSelectedDepartments/{departmentIds}")
@Timed
public ResponseEntity<Void> deleteSelectedDepartments(@PathVariable String departmentIds) {

（Spring MVC）如何从Rest API中检索多个对象
