axis2--一个简单的webService

1. 选择合适的版本下载axis2 .

   下载地址：http://axis.apache.org/axis2/java/core/.
   需要的文件为：axis2-1.7.3-bin.zip 和 axis2-1.7.3-war.zip

2. 环境初始化.

   (1).将axis2-1.7.3-war.zip解压.
   (2).将文件axis2.war放在tomcat的…\webapps\下.
   (3).启动tomcat,通过浏览器访问 http://127.0.0.1:8080/axis2.

3. 编写服务端代码.

MyService.java

public class MyService {
    public String HelloWebService(String str){
        //返回字符串
        return "Hello WebService, " + str;
    }   

}

将MyService.java编译后的MyService.class 放在tomcat下的…\webapps\axis2\WEB-INF\pojo(如果没有pojo则创建)中.

4.查看service的URL等信息.

浏览器访问http://127.0.0.1:8080/axis2/services/MyService?wsdl.
可以看到service的url 为http://127.0.0.1:8080/axis2/services/MyService.
方法名是HelloWebService.
5.编写客户端代码.
用到的jar包：http://download.csdn.net/detail/sinat_18831033/9554741.
ServiceClient.java

import javax.xml.namespace.QName;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.rpc.client.RPCServiceClient;


public class ServiceClient {
    public static void main(String[] args) {
        getString("I Coming !");
    }

    public static void getString(String str){
        try {
            //使用RPC方式调用WebService
            RPCServiceClient serviceClient = new RPCServiceClient();  
            Options options = serviceClient.getOptions();
            //指定调用WebService的URL 
            EndpointReference targetEPR = new EndpointReference(  
                    "http://127.0.0.1:8086/axis2/services/MyService");  
            options.setTo(targetEPR);
            // 指定参数值 
            Object[] opAddEntryArgs =
                    new Object[] {str}; 
        // 指定返回值的数据类型的Class对象 
            Class[] classes = new Class[] {String.class};
        // 指定要调用的方法及WSDL文件的命名空间 
            QName opAddEntry = new QName("http://ws.apache.org/axis2", "HelloWebService");
        // 调用方法并输出该方法的返回值 
            String reStr  =  serviceClient.invokeBlocking(
                    opAddEntry, opAddEntryArgs, classes)[0].toString();
            System.out.println(reStr);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

运行后输出：Hello WebService, I Coming !
