webservice（七）发布webservice为tomcat服务的方法

夜勿眠

　　操作循序：
　　此顺序基于契约优先原则，在我之前写过的webservice（六）的基础上进行修改
　　1.将wsdl拷贝到webContent下的WEB-INF中（导入JAX-RI包）

在wsdl中就可以使用include方式来导入了(暂时先不要进行导入，经测试发现导入可能引发问题)

修改实现类中的wsdlLocation的目录名
2.在web-inf下创建一个文件名为：sun-jaxws.xml

并进行如下修改：

<?xml version="1.0" encoding="UTF-8"?>

<endpoints xmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime"

version="2.0">

<!-- 1.Servlet中所需要对应的名称2.实现类3.浏览器的后缀 -->

<endpoint name="UserService" implementation="cn.edu.zttc.service.UserServiceImpl"

url-pattern="/us" />

</endpoints>
3.配置web.xml

加入监听器

<listener>

<listener-class>com.sun.xml.ws.transport.http.servlet.WSServletContextListener</listener-class>

</listener>

<servlet>

<servlet-name>UserService</servlet-name>

<servlet-class>com.sun.xml.ws.transport.http.servlet.WSServlet</servlet-class>

</servlet>

<servlet-mapping>

<servlet-name>UserService</servlet-name>

<url-pattern>/us</url-pattern>

</servlet-mapping>
　　

　　具体实例如下：
　　服务器端：

　　user.wsdl
