发送请求到spring rest api

Question

我正在使用intelliJIDEA，这是我的控制器：

@RequestMapping(value = "/api/authors", method = RequestMethod.POST)
public AuthorDTO addNewAuthor(@RequestBody AuthorDTO authorDTO) {
    return authorService.add(authorDTO);
}

（authorService.add返回AuthorDTO类型。）

AuthorDTD.java：

public class AuthorDTO {

public AuthorDTO() {
}

public AuthorDTO(Author author) {
    this.id = author.getId();
    this.first_name = author.getFirstName();
    this.last_name = author.getLastName();
}

public AuthorDTO(Long id, String first_name, String last_name) {
    this.id = id;
    this.first_name = first_name;
    this.last_name = last_name;
}

private Long id;
private String first_name;
private String last_name;
//getter/setters
 }

这是我的休息测试窗口：

但是当我发送POST请求时，没有任何反应！

json已发送：{"id":"12"}, {"first_name":"aaaa"}, { "last_name": "gggg"}

输出：

响应窗口：<Response body is empty>

运行日志：

Answer 1

检查JSON的格式，它应该是，

{"id":12, "first_name":"aaaa",  "last_name": "gggg"}

确保Content-Type标头设置为application/json
