java 调用 wsdl形式的webservice

来源：互联网发布：滤波算法编辑：程序博客网时间：2024/06/06 02:37

项目中有这样一个需求，调用运营商接口，给用户充值流量。但是接口地址是wsdl形式的。之前只是在.net开发的时候用WCF调用过接口。那么java如何实现调用wsdl形式的webservice呢？

网上有许多类似的问题，也有一些解决方法，有的说用了XFire解决了，有的说用了AXIS。于是我采用了第二种。

一、问题解决过程

1、下载AXIS2类库，AXIS2是目前java调用webservice的一个主要方法

首先说一下使用AXIS调用WSDL文件时需要的JAR包：
（1）axis 其中包括axis.jar、axis-ant.jar、commons-discovery-0.2.jar、commons-logging-1.0.4.jar、jaxrpc.jar、log4j-1.2.8.jar、log4j.properties、saaj.jar、wsdl4j-1.5.1.jar。
（2）mail.jar。
（3）activation.jar。

2、由于是第三方webservice，直接引入AXIS2的包就可以了。在调用和调错期间，我主要引了这么多的jar包：

3、代码：

    /**     * description：调用运营商充值接口方法     * author：xuxiaoguai     * 2015-12-1 10:32:04     * @return 返回值参数代码     */    public String invokeRemoteFuc() {        String endpoint="http://^^^^";        String result="no result!";        System.out.println(result);        Service service =new Service();        Call call;        Object[] object=new Object[4];  //Object用来存储方法的参数        object[0]="XXX";  //相应的参数，由于保密        object[1]="XXX";        object[2]="XXX";        object[3]="10M";        try {            call=(Call)service.createCall();            call.setTargetEndpointAddress(endpoint); //远程调用路径            call.setOperationName("methodname");  //调用的方法名            //设置参数名:            call.addParameter("XX", //参数名                    XMLType.XSD_STRING,//参数类型：String                    ParameterMode.IN); //参数模式：'IN' or 'OUT'            call.addParameter("XX", XMLType.XSD_STRING,ParameterMode.INOUT);            call.addParameter("XX", XMLType.XSD_STRING,ParameterMode.INOUT);            call.addParameter("XX", XMLType.XSD_STRING,ParameterMode.INOUT);            //设置返回值类型：            call.setReturnType(XMLType.XSD_STRING);   //返回值类型：String            result=(String) call.invoke(object);  //远程调用        }catch (ServiceException e) {            e.printStackTrace();        }catch (RemoteException e){            e.printStackTrace();        }        return result;    }    //测试充值接口方法-xuxiaoguai-2015年11月30日17:13:04    public static void main(String[] args){        BusinessController t=new BusinessController();        String result =t.invokeRemoteFuc();        System.out.println(result);    }

代码说明：由于接口和参数很重要，不能外漏，所以小编用了XX代替，在object数组中是对应参数的值，在

                   call.addParameter("XX", XMLType.XSD_STRING,ParameterMode.INOUT);

中对应的XX是指接口参数名称，我们还是分清一些的好。

二、一些错误

当然，小编也遇到了一些错误，都是一些缺少包的情况，我们去下载导入相应的jar包就好，但是还有一个问题作为附件吧，贴上来：

解决的方法是：去掉接口地址的 ?wsdl

中间还会报一些其他的错误，也就是参数不对应等参数错误了……

这种方式是直接直接AXIS调用远程的web service ，还有直接SOAP调用远程的webservice 的方法，还有使用wsdl2java把WSDL文件转成本地类，然后像本地类一样使用，但是后两种方法小编还没有尝试。
