java - cxf rest服务jboss部署异常

Question

致力于 CXF 休息服务。

这是界面

 import javax.ws.rs.GET;
    import javax.ws.rs.Path;
    import javax.ws.rs.PathParam;
    import javax.ws.rs.Produces;

    @Path("/example")
    @Produces("application/json")
    public interface TrackerService {

        @GET
        @Path("/{id}")
        public String get(@PathParam("id") String id);

    }

实现类

import org.springframework.stereotype.Service;

import com.service.TrackerService;

@Service("trackerService")
public class TrackerImpl implements TrackerService {

    public String get(String id) {
        // TODO Auto-generated method stub
        return "HELLO";
    }

web.xml，其中定义了 CXF servlet

<?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">

    <welcome-file>default.html</welcome-file>

  </welcome-file-list>

  <context-param>
        <param-name>contextConfigLocation</param-name>

    </context-param>

    <!-- Creates the Spring Container shared by all Servlets and Filters -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>



      <servlet>
        <servlet-name>CXFServlet</servlet-name>
        <servlet-class>
            org.apache.cxf.transport.servlet.CXFServlet
        </servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>CXFServlet</servlet-name>
        <url-pattern>/services/*</url-pattern>
    </servlet-mapping>


</web-app>

cxf-service.xml，其中注册了bean

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:jaxrs="http://cxf.apache.org/jaxrs"
       xmlns:cxf="http://cxf.apache.org/core"

       xsi:schemaLocation="

                        http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd">

    <context:component-scan base-package="com" />

    <jaxrs:server id="trackerCxfServer" address="/">
        <jaxrs:serviceBeans>
            <ref bean="trackerService"/>
        </jaxrs:serviceBeans>
        <jaxrs:extensionMappings>
            <entry key="json" value="application/json"/>
        </jaxrs:extensionMappings>
        <jaxrs:features>
            <cxf:logging/>
        </jaxrs:features>
        <jaxrs:providers>
            <bean class="com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider" />
        </jaxrs:providers>
    </jaxrs:server>

</beans>

将其添加到 jboss-6.2 eap 中，运行后出现以下异常

Answer 1

你应该添加这个库“cxf-rt-transports-http-x.x.x.jar”

我看到在你的 spring 配置中缺少这个导入

<import resource="classpath:META-INF/cxf/cxf.xml" /> 
<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" /> 
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />

E.G 来自 http://cxf.apache.org/docs/servlet-transport.html

<beans xmlns="http://www.springframework.org/schema/beans"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xmlns:jaxws="http://cxf.apache.org/jaxws"
      xmlns:jaxrs="http://cxf.apache.org/jaxrs"
      xsi:schemaLocation="
         http://www.springframework.org/schema/beans
         http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
         http://cxf.apache.org/jaxws
         http://cxf.apache.org/schemas/jaxws.xsd
         http://cxf.apache.org/jaxrs
         http://cxf.apache.org/schemas/jaxrs.xsd">

  <import resource="classpath:META-INF/cxf/cxf.xml"/>
  <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml"/>
  <import resource="classpath:META-INF/cxf/cxf-extension-jaxrs-binding.xml"/>
  <import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>

  <jaxws:endpoint id="greeter"
      implementor="org.apache.hello_soap_http.GreeterImpl"
      address="/Greeter1"/>

  <jaxrs:server id="greeterRest"
      serviceClass="org.apache.hello_soap_http.GreeterImpl"
      address="/GreeterRest"/> 

</beans>

通过 maven 依赖项 .. 我使用这些依赖项。
