cxf动态调用wsdl的一个冲突以及解决

时间：2022-10-25 19:54:14

cxf发布服务，调用服务的博客很多，这里也就简单贴一下代代码。

环境如下：spring+cxf (maven环境)

<cxf.version>2.7.11</cxf.version>

<!-- SOAP begin -->

        <dependency>

            <groupId>org.apache.cxf</groupId>

            <artifactId>cxf-rt-core</artifactId>

            <version>${cxf.version}</version>

            <exclusions>

                <!-- use javax.mail.mail instead -->

                <exclusion>

                    <groupId>org.apache.geronimo.specs</groupId>

                    <artifactId>geronimo-javamail_1.4_spec</artifactId>

                </exclusion>

                <!-- use javax.activation.activation instead -->

                <exclusion>

                    <groupId>org.apache.geronimo.specs</groupId>

                    <artifactId>geronimo-activation_1.1_spec</artifactId>

                </exclusion>

            </exclusions>

        </dependency>

        <dependency>

            <groupId>org.apache.cxf</groupId>

            <artifactId>cxf-rt-frontend-jaxws</artifactId>

            <version>${cxf.version}</version>

            <exclusions>

                <!-- see above -->

                <exclusion>

                    <groupId>org.apache.geronimo.specs</groupId>

                    <artifactId>geronimo-javamail_1.4_spec</artifactId>

                </exclusion>

                <exclusion>

                    <groupId>org.apache.geronimo.specs</groupId>

                    <artifactId>geronimo-activation_1.1_spec</artifactId>

                </exclusion>

            </exclusions>

        </dependency>

        <dependency>

            <groupId>org.apache.cxf</groupId>

            <artifactId>cxf-rt-transports-http</artifactId>

            <version>${cxf.version}</version>

        </dependency>

        <!-- SOAP end -->

服务端（jetty环境）：

@WebService

public interface ICommand {

    /**

     * 通用调用

     * @param fromApp

     * @return

     */

    public String isConnection(@WebParam(name="fromApp") String fromApp);

    public String sendCommand(@WebParam(name="fromApp")String fromApp, @WebParam(name="command")String command);

}
@WebService

public class CommandImpl implements ICommand {

    private final static Logger logger = LoggerFactory.getLogger(CommandImpl.class);

    @Override

    public String isConnection(String fromApp) {

        logger.info("from:" + fromApp);

        return "ok";

    }

    @Override

    public String sendCommand(String fromApp, String command) {

        logger.info("from:" + fromApp + ",name:" + command);

        // 调用自己生

        return "response:[" + command + "]";

    }

}

spring配置：

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"

 http://www.springframework.org/schema/context/spring-context.xsd

 http://cxf.apache.org/jaxws

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

  <!--CXF配置-->

   <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"/>

      <!--服务端发布的webservice 和下面的配置一样

      <jaxws:endpoint id="command" implementor="cn.edu.bupt.service.soa.CommandImpl" address="/Command"/>

-->

    <bean id="command" class="cn.edu.bupt.service.soa.CommandImpl"/>

    <jaxws:endpoint id="commandWebService" address="/Command" implementorClass="cn.edu.bupt.service.soa.CommandImpl">

        <jaxws:implementor ref="command"/>

    </jaxws:endpoint>

</beans>

客户端配置：

 <jaxws:client id="commandClient" address="http://localhost:8088/virtual-network/webservice/Command" serviceClass="cn.edu.bupt.service.soa.ICommand"/>

采用bean调用：

public static void main(String[] args){

   ApplicationContext context = new ClassPathXmlApplicationContext("spring-cxf.xml");

  ICommand helloWorld=(ICommand)context.getBean("commandClient");

  System.out.println(helloWorld.sendCommand("helloworld","Test"));

}

这边准备用cxf动态调用：

 public static void main(String[] args){

JaxWsDynamicClientFactory  factory =JaxWsDynamicClientFactory.newInstance();

     String url = "http://localhost:8088/virtual-network/webservice/Command?wsdl";

     org.apache.cxf.endpoint.Client client =factory.createClient(url);

      //url为调用webService的wsdl地址

    //QName也可以

     //QName name=new QName("http://soa.service.bupt.edu.cn/","isConnection");

     try {

//         Object[] obj =client.invoke(name, "helloworld");

         Object[] obj =client.invoke("isConnection", "helloworld");

         System.out.println("resp:"+obj[0]);

     } catch (Exception e) {

      e.printStackTrace();

     }

 }

由于我客户端和服务端是一起运行，报出异常：

Caused by: java.lang.reflect.InvocationTargetException

    at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)

    at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:57)

    ... 23 more

    at com.sun.xml.internal.bind.v2.model.core.Adapter.<init>(Adapter.java:73)

这个是为什么，因为项目引入的tools.jar与jaxb-impl.jar冲突了。

用mvn dependency:tree > tree.txt 导入包引用路径，发现是druid引入的tools导致的

[INFO] +- com.alibaba:druid:jar:1.0.9:compile

[INFO] |  +- com.alibaba:jconsole:jar:1.8.0:system

[INFO] |  \- com.alibaba:tools:jar:1.8.0:system

排除一下

<dependency>

            <groupId>com.alibaba</groupId>

            <artifactId>druid</artifactId>

            <version>${druid.version}</version>

            <exclusions>

                <exclusion>

                  <groupId>com.alibaba</groupId>

                  <artifactId>jconsole</artifactId>

                </exclusion>

                <exclusion>

                  <groupId>com.alibaba</groupId>

                  <artifactId>tools</artifactId>

                </exclusion>

            </exclusions>

</dependency>

就解决了该冲突。
