CXF session问题

说明：CXF作为Webservice很好的实现框架，让Webservice的开发变得极期方便（Xfire框架居说目前已经不再维护，使用越来越少了），然后在使用中也遇到很多细节问题，如Session会话问题就是其中一个，由于网上好多解决方法试了都不好用，最近刚刚解决了在此备份一下，以便以后使用方便。

 

一、建立Web工程，加入CXF的jar包，项目中使用的版本为cxf2.6.0。

 

 

二、定义两个接口IRegirstInfo、ILoginInfo； IRegirstInfo接口定一个注册方法，ILoginInfo定义一个登录方法。

 

 

@WebService
publicinterface IRegirstInfo {
publicvoid UserRegirstInfo();
}



@WebService
publicinterface ILoginInfo {
public String UserLoginDao(String token);
}

@WebService
public interface IRegirstInfo {
	public void UserRegirstInfo();
}



@WebService
public interface ILoginInfo {
	public String UserLoginDao(String token);
}

 

三、定义两个接口的实现类RegirstInfoService、UserLoginService ； RegirstInfoService服务类里生成一个Token信息，然后将它放到Session里，然后在UserLoginService 服务里我们从Session里取出这个Token信息。

 

 

@WebService
publicclass RegirstInfoService implements IRegirstInfo {
@Resource
private WebServiceContext wsContext;
private MessageContext mc;
private HttpSession session;

publicvoid UserRegirstInfo() {
// 获取上下文,保存request,session信息.
mc = wsContext.getMessageContext();
session = ((javax.servlet.http.HttpServletRequest) mc
.get(MessageContext.SERVLET_REQUEST)).getSession();

((javax.servlet.ServletContext) mc.get(MessageContext.SERVLET_CONTEXT))
.setAttribute("session", session);// 把session放到ServletContext中。

String token = UUID.randomUUID().toString(); // 生成Token

session.setAttribute("token", token); // 将生成的token放入Session
//生成request，来获取客户端的IP
HttpServletRequest request = (HttpServletRequest) mc
.get("HTTP.REQUEST");
System.out.println("request:" + request.getRemoteAddr());
}

}

@WebService  
public class RegirstInfoService implements IRegirstInfo {   
    @Resource  
    private WebServiceContext wsContext;   
    private MessageContext mc;   
    private HttpSession session;   
  
    public void UserRegirstInfo() {   
        // 获取上下文,保存request,session信息.   
        mc = wsContext.getMessageContext();   
        session = ((javax.servlet.http.HttpServletRequest) mc   
                .get(MessageContext.SERVLET_REQUEST)).getSession();   
  
        ((javax.servlet.ServletContext) mc.get(MessageContext.SERVLET_CONTEXT))   
                .setAttribute("session", session);// 把session放到ServletContext中。   
  
        String token = UUID.randomUUID().toString(); // 生成Token   
  
        session.setAttribute("token", token); // 将生成的token放入Session   
        //生成request，来获取客户端的IP   
        HttpServletRequest request = (HttpServletRequest) mc   
                .get("HTTP.REQUEST");   
        System.out.println("request:" + request.getRemoteAddr());   
    }   
  
}  

 

 

@webservice
publicclass UserLoginService implements ILoginInfo {
@Resource
private WebServiceContext wsContext;
private MessageContext mc;
private HttpSession session;

public String UserLoginDao(String token) {
mc = wsContext.getMessageContext();
session = (HttpSession) ((javax.servlet.ServletContext) mc
.get(MessageContext.SERVLET_CONTEXT)).getAttribute("session");
System.out.println("Token:" + session.getAttribute("token"));
return"Success--->" + token;
}

}

@webservice  
public class UserLoginService implements ILoginInfo {   
    @Resource  
    private WebServiceContext wsContext;   
    private MessageContext mc;   
    private HttpSession session;   
  
    public String UserLoginDao(String token) {   
        mc = wsContext.getMessageContext();   
        session = (HttpSession) ((javax.servlet.ServletContext) mc   
                .get(MessageContext.SERVLET_CONTEXT)).getAttribute("session");   
        System.out.println("Token:" + session.getAttribute("token"));   
        return "Success--->" + token;   
    }   
  
}  

 

四、web.xml

 

 

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>WEB-INF/beans.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<display-name>cxf</display-name>
<servlet>
<servlet-name>cxf</servlet-name>
<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>cxf</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>

<context-param>  
        <param-name>contextConfigLocation</param-name>  
        <param-value>WEB-INF/beans.xml</param-value>  
    </context-param>  
    <listener>  
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
    </listener>  
    <display-name>cxf</display-name>  
    <servlet>  
        <servlet-name>cxf</servlet-name>  
        <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>  
        <load-on-startup>1</load-on-startup>  
    </servlet>  
  
    <servlet-mapping>  
        <servlet-name>cxf</servlet-name>  
        <url-pattern>/*</url-pattern>  
    </servlet-mapping>  

 

五、还有一个bean.xml是用来发布服务的

 

 

<importresource="classpath:META-INF/cxf/cxf.xml"/>
<importresource="classpath:META-INF/cxf/cxf-extension-soap.xml"/>
<importresource="classpath:META-INF/cxf/cxf-servlet.xml"/>
<!-- ===============具体服务实例============= -->

<beanid="userLoginService"class="com.dyc.impl.UserLoginService"/>

<beanid="regirstInfoService"class="com.dyc.impl.RegirstInfoService"/>


<!-- ===============对外发布服务============= -->
<jaxws:endpointid="loginService"implementor="#userLoginService"
address="/LoginService">
</jaxws:endpoint>

<jaxws:endpointid="regirstService"implementor="#regirstInfoService"
address="/RegirstService">
</jaxws:endpoint>
