Question

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：

Answer 1

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）。

Answer 2

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();
    }
}

Answer 3

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。

Answer 4

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。

<init-param>
<param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
<param-value>true</param-value>
</init-param>

	</servlet>
	<servlet-mapping>
		<servlet-name>REST</servlet-name>
		<url-pattern>/rest/*</url-pattern>
	</servlet-mapping>
</web-app>

@GET
@Path("msg")
@Produces(MediaType.APPLICATION_JSON)
public HelloMessage getMessage() {
	HelloMessage obj = new HelloMessage();
	obj.setMessage("Hello World from object instance");
	return obj;
}
