Question

这是我第一次使用REST和Spring，在此之前我总是使用JAX RS和Guice实现。

无论如何，这是我的控制器

@Controller
@Api(value = "Redis Data Structures Service", description = "Spring REST Controller that handles all the HTTP requests for the Redis Data Structures Service.", position = 1)
@ManagedResource(description = "Redis Data Structures Service REST Controller")
@RestController
@EnableAutoConfiguration
@EnableSwagger
@RequestMapping("/datastructures/v1")
public class MyResource{
   @RequestMapping(value = "/process", method = RequestMethod.POST, produces = "application/json", consumes="application/json")
   public ResponseEntity<Operation> batch(@RequestBody Operation operation) throws JSONException{
       //this is just for testing
       operation.operationId = 123;
       return new ResponseEntity<Operation>(operation, HttpStatus.OK);
   }
}

这是Pojo of Operation类：

public class Operation{
   public int operationId;
   //get & set
}

以下是我从Advance Rest Client Google Chrome扩展程序调用的其他电话：

PATH : 
      <server:port>/datastructures/v1/process/
BODY : 
     {
       "operationId":10
     }
METHOD :
     POST
CONTENT TYPE : 
     application/json

在调用时，这是我得到的例外，

Required request body content is missing....with stack trace

这真是令人沮丧，这个简单的电话是杀死应用程序，:)。请帮助，提前谢谢

我删除了您的@Api和@EnableSwagger注释，因为我不知道他们来自哪个库。

此代码对我有用：

@Controller
@ManagedResource(description = "Redis Data Structures Service REST Controller")
@RestController
@EnableAutoConfiguration
@RequestMapping("/datastructures/v1")
public class Main {
    @RequestMapping(value = "/process", method = RequestMethod.POST, produces = "application/json", consumes="application/json")
    public ResponseEntity<Operation> batch(@RequestBody Operation operation) {
        //this is just for testing
        operation.operationId = 123;
        return new ResponseEntity<Operation>(operation, HttpStatus.OK);
    }

    public static void main(String[] args) {
        SpringApplication.run(Main.class, args);
    }

}

使用HTTPie：

$ http localhost:8080/datastructures/v1/process << EOF
heredoc : {
heredoc : "operationId": 5
heredoc : }
heredoc : EOF

HTTP/1.1 200 OK
Content-Type: application/json;charset=UTF-8
Date: Mon, 27 Apr 2015 05:55:37 GMT
Server: Apache-Coyote/1.1
Transfer-Encoding: chunked

{
    "operationId": 123
}

Spring boot 1.2.3.RELEASE

您的控制器上确实有@Controller和@RestController，这是不必要的，但不应该是您的问题的原因。检查您是否导入了正确的注释。
