客户端和服务器之间的连接正常,并且在服务器上调用了正确的函数addEpic。问题是,只在服务器上创建了一个新的Epic实例,但不使用客户端的属性。 @RequestBody似乎是个问题。不应该自动将@RequestBody从json数据转换为指定的类? Epic是@Entity类的根本问题是什么?
也可能是客户端错误地生成了正文。 console.log(正文)显示:
{"epic":{"id":"f97d885a-410f-fa6d-7adc-291e63d35341", "name":"OurName"}}
但我的招摇 - ui显示身体模型shema:
{"id":"string", "name":"string"}
客户端
addEpic(epic:Epic):Observable<any> {
let body = JSON.stringify({epic});
let headers = new Headers({'Content-Type': 'application/json'});
let options = new RequestOptions({headers: headers});
return this.http.post(url + "addEpic", body, options)
.map(this.extractHeader)
.catch(this.handleError);
}
export class Epic {
id: string;
name: string;
}
服务器
@RequestMapping(value="/addEpic", method = RequestMethod.POST)
public ResponseEntity<Void> addEpic(@RequestBody Epic epic) {
// Here it seems that constructor of epic is called and a new instance is created
epicRepository.saveAndFlush(epic);
return new ResponseEntity<Void>(HttpStatus.CREATED);
}

答案 0 :(得分:3)
您的实体Epic有两个属性&#39; id&#39;并且&#39; name&#39;。 在JSON中:
{"id":"string", "name":"string"}
这正是Swagger向您展示的内容。
所以你的客户做错了,你应该像那样创建JSON
let body = JSON.stringify(epic);
只需删除史诗般的超级{}。
