本文深入探讨了使用CXF与Spring框架进行整合时遇到的问题，包括客户端调用异常、WSDL绑定操作信息缺失及类型不匹配等，并提供了相应的解决策略。

1.见解

1.1 客户端的接口代码还一定要和服务端的接口代码一样,连注解都要一样,不够灵活

1.2 当客户端访问服务器的请求地址时,如果服务端没有对应的地址,就会报错,但是又没有cxf的异常捕获处理

1.3 address中的url是模糊匹配的

//服务端代码

2.UserBean.java

package cn.hk.bean;

public class UserBean {
	private int id;
	private String userName;
	private String password;
	public UserBean(){
		
		
	}
	public UserBean(int id, String userName, String password) {
		super();
		this.id = id;
		this.userName = userName;
		this.password = password;
	}
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getUserName() {
		return userName;
	}
	public void setUserName(String userName) {
		this.userName = userName;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	@Override
	public String toString() {
		return "UserBean [id=" + id + ", password=" + password + ", userName="
				+ userName + "]";
	}
	
	
}

3.IUserDao.java

package cn.hk.dao;

import java.util.List;

import javax.jws.WebParam;
import javax.jws.WebService;

import cn.hk.bean.UserBean;

@WebService
public interface IUserDao {

	public UserBean getUser(@WebParam(name="id") int id);
	public String getUserName(int id);
	public List<UserBean> getUserList();
}

4.IUserDaoImpl.java

package cn.hk.dao.impl;

import java.util.ArrayList;
import java.util.List;

import javax.jws.WebParam;
import javax.jws.WebService;

import cn.hk.bean.UserBean;
import cn.hk.dao.IUserDao;
@WebService
public class IUserDaoImpl implements IUserDao {

	@Override
	public UserBean getUser(@WebParam(name="id") int id) {
		
		 
		return new UserBean(id,"zhangsan","zhangsan");
	}

	@Override
	public List<UserBean> getUserList() {
		List<UserBean> list=new ArrayList<UserBean>();
		UserBean u1=new UserBean(1,"lisi","lisi");
		list.add(u1);
		u1=new UserBean(2,"wanwu","wanwu");
		list.add(u1);
		u1=new UserBean(3,"tiantian","tiantian");
		list.add(u1);
		return list;
	}

	@Override
	public String getUserName(int id) {
		
		return "id:"+id+"name:zhangsan";
	}

}

public interface IUserDao {

	public UserBean getUser(@WebParam(name="id") String  id);
	public String getUserName(String id);

3.InvokeUsersServices.java 调用

package cn.webservice.client;

import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;

import cn.hk.dao.IUserDao;

public class InvokeUsersServices {
	
	public static void main(String[] args) {
		
		JaxWsProxyFactoryBean factory=new JaxWsProxyFactoryBean();
		factory.setServiceClass(IUserDao.class);
		
		factory.setAddress("http://localhost:8085/cxfISprint/services/userss");
		IUserDao userDao=(IUserDao)factory.create();
		System.out.println(userDao.getUser("1"));
		System.out.println(userDao.getUserName("12"));
		System.out.println(userDao.getUserList().size());
	}
}

CXF整合Spring之JaxWsProxyFactoryBean调用异常

Exception in thread "main" java.lang.ClassCastException: org.apache.cxf.endpoint.ClientImpl cannot be cast to cn.hk.dao.IUserDao

at cn.webservice.client.InvokeUsersServices.main(InvokeUsersServices.java:13)

cause 是JaxWsProxyFactoryBean对象,不是JaxWsClientFactoryBean对象

Exception in thread "main" javax.xml.ws.WebServiceException: Could not find wsdl:binding operation info for web method getUserName.

at org.apache.cxf.jaxws.JaxWsClientProxy.invoke(JaxWsClientProxy.java:113)

at $Proxy17.getUserName(Unknown Source)

at cn.webservice.client.InvokeUsersServices.main(InvokeUsersServices.java:14)

cause 客户端的接口也庶加@WebService注解

object is not an instance of declaring class while invoking public java.lang.String cn.hk.dao.impl.IUserDaoImpl.getUserName(int) with params [10].

... 2 more

cause jaxws:serviceBean一定要引用接口的实现类
