Question

我尝试使用JQuery连接到Jersey服务。但是，它没有连接到服务，因为我检查日志是否已经达到服务。有什么遗漏？

$('#update').click(function() {
    alert("updating the labelll");
    $.ajax({
        url:"/updatecontent",
        type: 'POST',
        dataType:"json",
        data:$( "#labels option:selected" ).text(),
        async:false,
        success:function(contentdata) { // Success Call Back Function.
            if(contentdata == "1") {
                alert("successfully updated");
            } else {
                alert("sorry.. failed in updating");
            }
        },
        error:function(){ // Error Call back function.
            alert("sorry.. failed in updating in Error call back");
        }
    });

});

服务 ---------

@Path("/updatecontent")
public class updatecontent {

private static final org.slf4j.Logger     LOGGER=org.slf4j.LoggerFactory.getLogger(updatecontent.class);

@Context
HttpServletRequest request;
@Context
HttpServletResponse response;
@POST
@Consumes(MediaType.APPLICATION_JSON)
public String updateStatus(String packet) throws JSONException {

    // Get the object from the UI.
    LOGGER.info("In the API class of updating content for review.");
    return "1";

}
}



 Web.xml 
---------
 <servlet>
 <servlet-name>jersey-serlvet</servlet-name>
 <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
 <init-param>
  <param-name>com.sun.jersey.config.property.packages</param-name>
  <param-value>net.my.services</param-value>
 </init-param>
 <init-param>
    <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
    <param-value>true</param-value>
 </init-param>
 <load-on-startup>6</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>jersey-serlvet</servlet-name>
 <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

我在这里遗漏了什么？应该有一个小问题。任何想法都将不胜感激。

您的web.xml有url-pattern

<url-pattern>/rest/*</url-pattern>

所以jQuery必须连接到

/rest/updatecontent

无法使用jquery调用Jersey服务
