Java 缺少必需的请求正文

我在春天和休息时是新来的。 我写了这样一个简单的休息：

@RequestMapping(value = "/loginTest", method = RequestMethod.POST)
@ResponseBody
public Response loginTest(@RequestBody LoginRequest request) {
    System.out.println("enter loginTest.");
    String account = request.getAccount();
    String password = request.getPassword();
    Response res = new Response();
    return res;
}

public class LoginRequest {
    private String account;
    private String password;
    public String getAccount() {
        return account;
    }
    public void setAccount(String account) {
        this.account = account;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
}

登录请求如下所示：

@RequestMapping(value = "/loginTest", method = RequestMethod.POST)
@ResponseBody
public Response loginTest(@RequestBody LoginRequest request) {
    System.out.println("enter loginTest.");
    String account = request.getAccount();
    String password = request.getPassword();
    Response res = new Response();
    return res;
}

public class LoginRequest {
    private String account;
    private String password;
    public String getAccount() {
        return account;
    }
    public void setAccount(String account) {
        this.account = account;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
}

当我通过命令进行测试时：

curl -X POST "{"account": "aaa","password": "bbb"}" -H "Content-type:application/json" http://localhost:8080/user/loginTest

但我得到了结果：

[1/2]: account: aaa --> <stdout>
--_curl_--account: aaa
curl: (6) Could not resolve host: account; nodename nor servname provided, or not known
{
  "timestamp" : "2015-12-30T16:24:14.282+0000",
  "status" : 400,
  "error" : "Bad Request",
  "exception" : "org.springframework.http.converter.HttpMessageNotReadableException",
  "message" : "Bad Request",
  "path" : "/user/loginTest"
}

类LoginRequest是否需要注释？因为Jason无法转换为类？

有人能帮我解决这个问题吗？

请求正文应该在curl中的--data开关中发送

看到这个了吗

所以你的请求现在应该是

curl -X POST --data '{"account": "aaa","password": "bbb"}' -H "Content-Type:application/json"  http://localhost:8080/user/loginTest

另外，如果您可以在发送请求的机器上运行浏览器，那么您可以尝试一些REST客户端插件。它们更易于使用，并提供保存请求和历史记录功能。 检查
