我有一個將JSON發佈到Jersey REST服務的問題 - GET工作正常,但POST看起來很棘手。我一直在研究這個問題一段時間,目前還沒有解決方案。任何幫助深表感謝! ?發佈POST JSON到Jersey REST服務
看來它不能找到在U RL發送JSON這裏是螢火控制檯顯示:
POST http://localhost:9998/data 400 Bad Request
Post source: name=Tony
**Response Headers**
Connection close
Content-Length 0
Content-Type text/html; charset=iso-8859-1
Date Fri, 20 Apr 2012 10:13:24 GMT
**Request Headers**
Accept application/json, text/javascript, */*; q=0.01
Accept-Encoding gzip, deflate
Accept-Language sv-se,sv;q=0.8,en-us;q=0.5,en;q=0.3
Connection keep-alive
Content-Length 9
Content-Type application/json; charset=UTF-8
Host localhost:9998
Referer http://localhost:9998/static/page.html
User-Agent Mozilla/5.0 (Windows NT 6.1; WOW64; rv:11.0) Gecko/20100101 Firefox/11.0
X-Requested-With XMLHttpRequest
我做的是POST如下:
<button id='btn' value="knapp" name="knapp" />
<script type="text/javascript">
$('#btn').click(function(){
$.ajax({
url: '/data',
type: 'POST',
contentType: 'application/json',
data: {name:"Tony"},
dataType: 'json'
});
})
</script>
JavaBean類與@XmlRootElement:
@XmlRootElement
public class StatusBean {
private String name;
public StatusBean() {
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
資源方法:
@Path("/data")
public class PostData {
@POST
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public StatusBean post(StatusBean sb) {
System.out.println(sb);
return sb;
}
}
的服務器,建立與灰熊:
public class Main {
public static final URI BASE_URI = getBaseURI();
public static void main(String[] args) throws IOException {
HttpServer httpServer = startServer();
Map<String,String> initParams = new HashMap<String, String>();
initParams.put("com.sun.jersey.config.property.packages", "server");
SelectorThread selector = GrizzlyWebContainerFactory.create("http://localhost:9998/", initParams);
System.out.println(String.format("Jersey app started with WADL available at "
+ "%sapplication.wadl\nTry out %shelloworld\nHit enter to stop it...",
BASE_URI, BASE_URI));
System.in.read();
httpServer.stop();
}
protected static HttpServer startServer() throws IOException {
System.out.println("Starting grizzly...");
ClassNamesResourceConfig rc = new ClassNamesResourceConfig(PostData.class);
// rc.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, true);
HttpServer server = GrizzlyServerFactory.createHttpServer(BASE_URI, rc);
server.getServerConfiguration().addHttpHandler(new StaticHttpHandler(new File(".").getAbsolutePath()), "/static");
return server;
}
private static int getPort(int defaultPort) {
String port = System.getProperty("jersey.test.port");
if (null != port) {
try {
return Integer.parseInt(port);
} catch (NumberFormatException e) {
}
}
return defaultPort;
}
private static URI getBaseURI() {
return UriBuilder.fromUri("http://localhost/").port(getPort(9998)).build();
}
}
檢查服務器日誌,還有什麼存在 - 找一個異常和粘貼堆棧跟蹤。 – 2012-04-20 11:28:52
沒有在服務器日誌中,這就是問題 – nihulus 2012-04-20 11:31:03
你可以發佈你的web.xml,所以我們可以看到JAX-RS配置? – 2012-04-20 11:33:03
