问题描述

有人可以帮助我..吗? 我正在尝试使用JAX-RS创建Web服务，但这给了我这个例外:

Can anyone help me .. ? i m trying to create a Web Service with JAX-RS but it gives me this exception : 

SEVERE: Missing dependency for field: private    org.glassfish.jersey.server.wadl.WadlApplicationContext

org.glassfish.jersey.server.wadl.internal.WadlResource.wadlContext

org.glassfish.jersey.server.wadl.internal.WadlResource.wadlContext

这是我的Java类代码:

here is my java classe's code: 

@Path("/DataJson")
public class Ressources {

@GET
@Produces(MediaType.APPLICATION_JSON)
public Response test(){

String result = "@Produces(\"application/json\") Output: \n\nF to C Converter Output:     \n\n TEST SUCCESFUL";

return Response.status(200).entity(result).build();
}
}

-Web.xml部分:

--- Web.xml part : 

<servlet>
    <servlet-name>Jersey Web Application</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>

</servlet>
<servlet-mapping>
    <servlet-name>Jersey Web Application</servlet-name>
    <url-pattern>/ws/*</url-pattern>
</servlet-mapping>

----使用的罐子是:

---- the jar used are :

  • javax.annotation-api-1.2.jar
  • javax.ws.rs-api-2.0.jar
  • jersey-bundle-1.17.jar
  • jersey-client-2.0.jar
  • jersey-common-2.0.jar
  • jersey-container-servlet.jar
  • jersey-multipart-1.14.jar
  • jersey-server-2.0.jar
  • json.jar
  • mimepull-1.9.jar
  • asm-3.3.1.jar
  • javax.annotation-api-1.2.jar
  • javax.ws.rs-api-2.0.jar
  • jersey-bundle-1.17.jar
  • jersey-client-2.0.jar
  • jersey-common-2.0.jar
  • jersey-container-servlet.jar
  • jersey-multipart-1.14.jar
  • jersey-server-2.0.jar
  • json.jar
  • mimepull-1.9.jar
  • asm-3.3.1.jar

-----而且这正是我的例外情况:

----- AND this is exactly the exception i have :

推荐答案

似乎缺少一个初始化参数，您在其中指定了要在其中搜索带注释的WS资源的程序包.

Seems like you are missing an init param, where you specify the package where to search for annotated WS resources.

<servlet>
    <servlet-name>Jersey Web Application</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>package.to.your.class</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Jersey Web Application</servlet-name>
    <url-pattern>/ws/*</url-pattern>
</servlet-mapping>
