Apache CXF
Web Service的使用
- java有提供webservice规范、实现支持。
可参考文档
- 一般在开发时候，都是使用一些框架进行webservice开发。例如：ApacheCXF
WebService框架的性能测试 : https://blog.csdn.net/ck4438707/article/details/53610124
Apache CXF使用WebService(jax-ws规范)
独立程序的使用
服务端
- 添加依赖
- 如果是一个独立程序,比如jar,就需要内置服务器
- 注意使用webService,jre环境必须要是1.5以上

jax.setAddress("http://127.0.0.1:9999/Hello");

//添加日志拦截器,观察soap协议内容

//发布服务
jax.create();
System.out.println("服务开启成功!!端口号:9999");
}
}- 打开address的wsdl

接口

}- 远程调用服务
/**

*/
public class Client {
/**

JaxWsProxyFactoryBean jax = new JaxWsProxyFactoryBean();
//设置远程访问的服务的地址

jax.setServiceClass(UserServer.class);
//生成服务接口的代理对象
UserServer userService = jax.create(UserServer.class);
//通过代理对象,远程调用服务方法
String welcome = userService.welcome("Hello");
//测试
System.out.println(welcome);
}
}客户端输出
Hello,welcome!!服务端输出
- 观察SOAP协议的内容
- boby的请求参数是Hello
- 返回的参数是Hello,welcome!!
