CXF客户端添加拦截器报错

悠悠 2022-07-15 13:17 289阅读 0赞

**（1）错误类型：not a proxy instance**

Exception in thread "main" java.lang.IllegalArgumentException: not a proxy instance
    	at java.lang.reflect.Proxy.getInvocationHandler(Proxy.java:811)
    	at org.apache.cxf.frontend.ClientProxy.getClient(ClientProxy.java:93)
    	at lee.ClientMain.main(ClientMain.java:18)

**        错误代码如下：**

//这是 wsdl2java 命令生成的类，该类的实例可当成工厂来使用
    HelloWorldWs factory = new HelloWorldWs();
    //下面三行代码完成拦截
    Client client = ClientProxy.getClient(factory);
    client.getInInterceptors().add(new LoggingInInterceptor());
    client.getOutInterceptors().add(new LoggingOutInterceptor());
    //无参的方法，返回的是远程Web Service服务端的代理
    HelloWorld helloWorld = factory.getHelloWorldWsPort();
    //完成要实现的功能
    StringFood allFoods = helloWorld.getAllFoods();

**        错误原因：没有一个代理实例**

**        正确代码如下：**

//这是 wsdl2java 命令生成的类，该类的实例可当成工厂来使用
    HelloWorldWs factory = new HelloWorldWs();
    //无参的方法，返回的是远程Web Service服务端的代理
    HelloWorld helloWorld = factory.getHelloWorldWsPort();
    //下面三行代码完成拦截
    Client client = ClientProxy.getClient(helloWorld);
    client.getInInterceptors().add(new LoggingInInterceptor());
    client.getOutInterceptors().add(new LoggingOutInterceptor());
    //完成要实现的功能
    StringFood allFoods = helloWorld.getAllFoods();

**（2）错误类型：缺少客户端运行必需的 jar 包（将服务端所有的 jar 包都导入客户端肯定不会报错，我写的服务端 jar 包地址：http://pan.baidu.com/s/1jHJ56BW ）**

**        最简单的客户端需要4个 jar 包：cxf-2.4.jar、neethi-3.0.0.jar、wsdl4j-1.6.2.jar、xmlschema-core-2.0.jar**

**        缺少第一个 jar 包拦截器无法写入程序；**

**        缺少第二个 jar 包报错：**
