我试图得到一个简单的Jetty / SpringMVC示例，并遇到了一个我无法解决的问题。
我使用的类看起来像这样：
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.servlet.ServletContextHandler;
import org.eclipse.jetty.servlet.ServletHolder;
import org.springframework.web.context.ContextLoaderListener;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.servlet.DispatcherServlet;
public class JettyTest {
public static void main(String[] args) throws Exception {
AnnotationConfigWebApplicationContext spring = new AnnotationConfigWebApplicationContext();
spring.scan("controllers");
DispatcherServlet servlet = new DispatcherServlet(spring);
ServletHolder servletHolder = new ServletHolder(servlet);
servletHolder.setName("spring");
ServletContextHandler springHandler = new ServletContextHandler(
ServletContextHandler.NO_SESSIONS);
springHandler.setContextPath("/");
springHandler.addServlet(servletHolder, "/*");
springHandler.setErrorHandler(null);
springHandler.addEventListener(new ContextLoaderListener(spring));
Server server = new Server(5050);
server.setHandler(springHandler);
server.setStopAtShutdown(true);
server.start();
server.join();
}
}
控制器：
package controllers;
import model.MessageRequest;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class TestController {
@RequestMapping(value = "/message", method = RequestMethod.POST, consumes = "application/json")
public ResponseEntity<String> testPost(@RequestBody MessageRequest messageRequest) {
return new ResponseEntity<>("POST Response: " + messageRequest.getMessage(), null,
HttpStatus.OK);
}
}
最后是MessageRequest类：
package model;
public class MessageRequest {
private String message;
public void setMessage(String message) {
this.message = message;
}
public String getMessage() {
return message;
}
}
但是，当我启动此应用程序并使用以下请求正文发送POST请求时：
{
"message" : "test"
}
我收到以下回复：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8"/>
<title>Error 415 Unsupported Media Type</title>
</head>
<body>
<h2>HTTP ERROR 415</h2>
<p>Problem accessing /message. Reason:
<pre> Unsupported Media Type</pre>
</p>

我究竟做错了什么？我有一个类似的例子与Springboot合作，但在这里我不知何故失去了。
尝试添加
produces = "application/json"
同样。
