为什么设计拦截器？

为了在webservice请求中，可以主动操作请求和相应数据，CXF设计了拦截器。

拦截器分类：

1.按照所处的位置分：服务端拦截器、客户端拦截器；

2.按照消息的方向划分：入拦截器、出拦截器；

3.按照定义者划分：系统拦截器，自定义拦截器。

拦截器API

拦截器接口：

AbstractPhaseInterceptor

LoggingInInterceptor

LoggingOutInterceptor

那么我们就以日志拦截器为例，直接上代码：

服务端：

package com.service;

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService
public interface myWS {

	@WebMethod
	public String sayHello(String name);
	
}

package com.service;

import javax.jws.WebService;

@WebService
public class myWSImpl implements myWS {

	@Override
	public String sayHello(String name) {
		System.out.println("SERVER SAYHELLO!"+name);
		return "hello !"+name;
	}

}

package com.test;

import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.EndpointImpl;
import org.apache.cxf.phase.AbstractPhaseInterceptor;

import com.service.myWSImpl;

public class RRRR {

	public static void main(String[] args) {
		
		String address = "http://localhost:8989/sayHello";

		//发布服务端
		EndpointImpl epi = (EndpointImpl) EndpointImpl.publish(address, new myWSImpl());
		//服务端入拦截器添加一个日志入拦截器
		epi.getInInterceptors().add(new LoggingInInterceptor());
		//服务端出拦截器添加一个日志出拦截器
		epi.getOutInterceptors().add(new LoggingOutInterceptor());
		//发布服务
		System.out.println("WebService 发布成功 , address : " + address);
		
		
	}

}

可以通过日志看出服务端和客户端交互的数据。
