我在将 JSON 发布到 Jersey REST 服务时遇到问题 - GET 运行良好,但 POST 似乎很棘手。我一直在研究这个问题一段时间,到目前为止还没有解决方案。任何帮助深表感谢!
似乎找不到发送 json 的 URL?这是 FireBug 控制台显示的内容:
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

我正在按如下方式进行 POST:
<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>
带有@XmlRootElement 的Javabean 类:
@XmlRootElement
public class StatusBean {
private String name;
public StatusBean() {
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
资源方式:
@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;
}
}
使用 Grizzly 设置的服务器:
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();
}
}
