我是 Spring and Rest 的新手。 我像这样写了一个简单的休息:

@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; 
} 

LoginRequest 是这样的:

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; 
    } 
} 

当我通过命令测试它时:

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

但是我得到了结果:

[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" 
} 

还有在 eclipse 控制台中:

Failed to read HTTP message: org.springframework.http.converter.HttpMessageNotReadableException: Required request body is missing: public com.test.response.Response com.test.service.UserService.loginTest(com.test.model.request.LoginResquest) 

类 LoginRequest 是否需要注解？因为 Jason 无法转换为类？ 谁能帮我解决这个问题？

请您参考如下方法:

请求体应该在--data开关中发送，在curl中。

查看此 https://superuser.com/questions/149329/what-is-the-curl-command-line-syntax-to-do-a-post-request

所以你的请求现在应该变成

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

此外，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this plugin
