我正在尝试使用 Jersey 运行 REST-FUL Java GET方法，没有任何问题，但是当我将任何方法从GET更改为POST时，我Web服务器抛出错误
java.lang.ClassNotFoundException: com.sun.jersey.core.spi.factory.ResponseImpl
这是我的代码类实现：
@Path("/entrega")
public class EntregaWebServiceREST extends WebServiceParentREST {
static Logger log = Logger.getLogger(EntregaWebServiceREST.class.getName());
private EntregaService entregaService;
public EntregaWebServiceREST() {
entregaService = context.getBean(EntregaService.class);
}
@POST
@Produces("text/plain")
@Consumes("text/xml")
@Path("/sendWorkerToClient")
public String setWorkerToClient(@RequestParam("xml")
String xml) {
try {
return entregaService.setWorkerToClient(xml);
} catch (Exception e) {
log.error(e);
e.printStackTrace();
return "ocurrio una excepcion: " + e.getMessage();
}
}
}
这是我的pom.xml：

问题似乎是类加载器选择与应用程序不兼容的类（因此J9VMInternal.verify失败）。要解决此问题，您需要指定类加载器顺序 - 首先使用本地类加载器加载类（父级最后一个）。
答案 1 :(得分：0)
如果您想要发布的结果，请在您的课程中添加以下方法：
@POST
@Produces("text/plain")
@Consumes("text/xml")
@Path("/sendWorkerToClient")
public String setWorkerToClient_post(@RequestParam("xml")
String xml) {
try {
return entregaService.setWorkerToClient(xml);
} catch (Exception e) {
log.error(e);
e.printStackTrace();
return "ocurrio una excepcion: " + e.getMessage();
}
}
答案 2 :(得分：0)
ClassNotFoundException意味着类加载器无法找到com.sun.jersey.core.spi.factory.ResponseImpl。在你的pom文件中，我没有看到对jersey core的依赖，所以你需要在你的maven pom中添加它。
答案 3 :(得分：0)
我遇到同样的问题，例如“错误500：java.lang.NoClassDefFoundError：com.sun.jersey.core.spi.factory.ResponseImpl”
但是当我将以下代码添加到web.xml文件时，它解决了这个问题。
