1、首先编写Wsdl（基于契约优先的方式），要注意的是命名空间（若是使用include或import）最好使用一致的，代码如下：
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
xmlns:tns="http://www.xiaoqiaolv/ws"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
name="UserServiceImpl"
targetNamespace="http://www.xiaoqiaolv/ws">
<wsdl:types>
<xsd:schema targetNamespace="http://www.xiaoqiaolv/ws">
<!-- <xsd:include schemaLocation="UserSchema.xsd"/> -->
<!-- <xsd:import namespace="http://www.xiaoqiaolv/ws" schemaLocation="UserSchema.xsd"/>--> <xsd:element name="add" type="tns:add"/>

<xsd:element name="delete" type="tns:delete"/>
<xsd:element name="deleteResponse" type="tns:deleteResponse"/>
<xsd:element name="login" type="tns:login"/>

<wsdl:port binding="tns:userBinding" name="UserServiceImplPort">
<soap:address location="http://localhost:9999/ws"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>
2、实现服务器端的应用实现，这个就不加代码了，根据wsdl文档用wsimport生成服务，只取出接口service，然后其他的和我们正常的web开发都一致。
3、服务端发布服务：public static void main(String[] args) {
Endpoint.publish("http://localhost:9999/ws", new UserServiceImpl());
}
4、实现客户端：根据服务网址http://localhost:9999/ws，生成服务，得到所有以.java为后缀的类，把整个包包含在自己的项目中
5、编写测试类：代码如下：
public class Test {
private UserService userService;
private UserServiceImpl userServiceImpl;
public void testWsdl(){
try {
URL url = new URL("http://localhost:9999/ws?wsdl");
QName qname = new QName("http://www.xiaoqiaolv/ws","UserServiceImpl");
userServiceImpl = new UserServiceImpl(url,qname);
userService = userServiceImpl.getUserServiceImplPort();
User user = new User();
user.setUsername("aaa");
user.setPassword("1111");
user.setId(21212);
userService.add(user);
List<User> list = userService.list();
for(User u:list){
System.out.println(u.getUsername());
}
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static void main(String[] args) {
new Test().testWsdl();
}
}
6、有问题的话可以打开tcpmon，对接口服务进行监听，查看客户端与服务端传递的信息java -jar tcpmon.jar
