本文详细介绍了如何通过CXF在Java环境中实现基于JAX-WS的Web服务，包括配置文件、服务接口、实现类以及依赖库的引入。展示了如何将服务部署到Servlet容器并使用Spring进行初始化，最终通过浏览器访问服务实现互操作。

CXF 不支持 RPC/encoding 风格. RPC/literal 是WS-l BP 中定义的, 唯一一种能够用于互操作的.

CXF 有多种运行方式, 以下描述, 依赖 Servlet容器和 spring 的运行方式.

JAX-WS = JAX-RPC 2.0

Hi.java

@WebService
public interface Hi {
	String sayHi(String text);
}

HiImpl.java

package hi;

@WebService(endpointInterface = "hi.Hi")
public class HiImpl implements Hi {

	public String sayHi(String msg) {
		return "Hi " + msg;

附件提供一个可运行的例子. 字符行下进入项目目录, 运行 mvn package jetty:run, 浏览器打开 http://localhost:8080/service 即可看到服务列表.

默认生成的服务是 document/literal 风格的

enjoy it! that's all

wsdl > service
