基于Axis 1.4的Web Service入门

最近有个客户使用的是Axis 1.4创建的Web Service，很久没用了，所以整理下这块的知识。

基于JDK 1.8和Eclipse Mars开发一个简单的Hello world Web Service

public interface HelloService {

  String hello(String name);
}

public class HelloServiceImpl implements HelloService{

  @Override
  public String hello(String name) {
    return String.format("%s, 您好",name);
  }

}

右键单击HelloService的实现类，选择Web Services -> Create Web Service, 经过下面的配置后，一路Next基本就可以创建客户端项目了。

常规调用方式1：

private HelloServiceImplProxy helloServiceImplProxy = new HelloServiceImplProxy();

String helloTerry = helloServiceImplProxy.hello("程英华的博客");

其他方式：以使用HttpClient为例,这里的重点不是请求方式，而是工具SOAP UI 让我们快速的基于wsdl来创建请求，查看响应。这个工具是本人认为是其他方式的重点。

StringBuilder params = new StringBuilder();
params.append("<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:impl=\"http://impl.soap.hello.penguin.org\">\n" +
" <soapenv:Header/>\n" +
" <soapenv:Body>\n" +
" <impl:hello>\n" +
" <impl:name>兰博</impl:name>\n" +
" </impl:hello>\n" +
" </soapenv:Body>\n" +
"</soapenv:Envelope>");

WebServiceClientUtil webServiceClientUtil = new WebServiceClientUtil();
Result<?> result= webServiceClientUtil.createOaSoap(params.toString());
