上一节中已经成功的发布了一个服务端webservice,这一部分将默认客户端调用webservice
这里我们重新建立了一个新的工程CXF-Client,把上一节中列举的jar包都搞过来即可,调用方式采用了和RMI类似的机制,即客户端直接服务器端提供的服务接口(interface),CXF通过运行时代理生成远程服务的代理对象,在客户端完成对webservice的访问
几个必填的字段:setAddress-这个就是我们发布webservice时候的地址,保持一致
HelloWorldService:需要服务器端提供单独的Jar文件过来
package com.crazycoder2010.webservice.cxf.client; import org.apache.cxf.interceptor.LoggingInInterceptor; import org.apache.cxf.interceptor.LoggingOutInterceptor; import org.apache.cxf.jaxws.JaxWsProxyFactoryBean; import com.crazycoder2010.webservice.cxf.server.HelloWorldService; public class Client { public static void main(String[] args) { JaxWsProxyFactoryBean bean = new JaxWsProxyFactoryBean(); bean.getInInterceptors().add(new LoggingInInterceptor()); bean.getInFaultInterceptors().add(new LoggingOutInterceptor()); bean.setServiceClass(HelloWorldService.class); bean.setAddress("http://localhost:9090/helloWorldService"); HelloWorldService helloWorldService = (HelloWorldService)bean.create(); String result = helloWorldService.sayHello("Kevin"); System.out.println(result); } }
运行输出:
2011-8-9 21:32:20 org.apache.cxf.service.factory.ReflectionServiceFactoryBean buildServiceFromClass 信息: Creating Service {http://server.cxf.webservice.crazycoder2010.com/}HelloWorldServiceService from class com.crazycoder2010.webservice.cxf.server.HelloWorldService 2011-8-9 21:32:41 org.apache.cxf.interceptor.AbstractLoggingInterceptor log 信息: Inbound Message ---------------------------- ID: 1 Response-Code: 200 Encoding: UTF-8 Content-Type: text/xml;charset="utf-8" Headers: {Content-type=[text/xml;charset="utf-8"], Transfer-encoding=[chunked]} Payload: <?xml version="1.0" ?><envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><body><sayhelloresponse xmlns:ns2="http://server.cxf.webservice.crazycoder2010.com/"><return>Hello Kevin</return></sayhelloresponse></body></envelope> -------------------------------------- Hello Kevin小结:这种调用service的好处在于调用过程非常简单,就几行代码就完成一个webservice的调用,但是客户端也必须依赖服务器端的接口,这种调用方式限制是很大的,要求服务器端的webservice必须是java实现--这样也就失去了使用webservice的意义

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
