Question

我尝试使用jersey moxy来测试json，我的maven依赖只有版本为2.22.2的'jersey-media-moxy'。

web.xml如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>webapp</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>

<servlet>
    <servlet-name>Jersey REST Service</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>    
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Jersey REST Service</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>
</web-app>

Json服务类是：

@Path("/json")
public class JsonService {

    @GET
    @Path("/get")
    @Produces(MediaType.APPLICATION_JSON)
    public JsonObject getJson() {
        JsonObject obj = new JsonObject();
        obj.setId(1);
        obj.setName("json_test");
        return obj;
    }

    @POST
    @Path("/post")
    @Consumes(MediaType.APPLICATION_JSON)
    public Response createJson(JsonObject obj) {

        String result = "json object saved : "+obj;
        return Response.status(201).entity(result).build();
    }
}

但是，当我在eclipse中使用Tomcat 8.0运行此项目时，请键入

http://localhost:8080/webapp/rest/json/get

抛出以下错误：

A MultiException has 2 exceptions.  They are:
1. java.lang.NoSuchFieldError: WADL
2. java.lang.IllegalStateException: Unable to perform operation: create on org.glassfish.jersey.server.wadl.processor.WadlModelProcessor

    org.jvnet.hk2.internal.ClazzCreator.create(ClazzCreator.java:394)
    .........

root cause
java.lang.NoSuchFieldError: WADL
    org.glassfish.jersey.server.wadl.processor.WadlModelProcessor.<init>(WadlModelProcessor.java:96)
    .........

我的pom如下：

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        <artifactId>jersey-media-moxy</artifactId>

    </dependency>
  </dependencies>
</project>

有什么问题？
