spring + springmvc + cxf 实现webservice restful

cxf-server.xml cxf 服务器端的配置这里我没有和spring的配置放在一起，而是独立出来的

workflow-servlet.xml sprinmvc 配置文件也贴出来吧

所需要的jar包全部截图：

例子很简单没有涉及业务

接口：

package com.weir.webservice;

import javax.jws.WebService;
import javax.ws.rs.GET;
import javax.ws.rs.Path;

//@WebService
@Path(value="/userexit")
public interface UserExit {

	@GET
	@Path("/exitUser")
	public boolean exitUser();
}

实现：

package com.weir.webservice;

import javax.jws.WebService;
import javax.ws.rs.GET;
import javax.ws.rs.Path;

//@WebService(endpointInterface="com.weir.webservice.UserExit")
@Path(value="/userexit")
public class UserExitImpl implements UserExit {

	@GET
	@Path("/exitUser")
	public boolean exitUser() {
		System.out.println("lllll");
		return false;
	}

}

启动tomcat就可以了：
