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。

Java代码

1. @WebService
2. publicinterface IRegirstInfo {
3. publicvoid UserRegirstInfo();
4. }
8. @WebService
9. publicinterface ILoginInfo {
10. public String UserLoginDao(String token);
11. }

@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。

Java代码

1. @WebService
2. publicclass RegirstInfoService implements IRegirstInfo {
3. @Resource
4. private WebServiceContext wsContext;
5. private MessageContext mc;
6. private HttpSession session;
8. publicvoid UserRegirstInfo() {
9. // 获取上下文,保存request,session信息.
10. mc = wsContext.getMessageContext();
11. session = ((javax.servlet.http.HttpServletRequest) mc
12. .get(MessageContext.SERVLET_REQUEST)).getSession();
14. ((javax.servlet.ServletContext) mc.get(MessageContext.SERVLET_CONTEXT))
15. .setAttribute("session", session);// 把session放到ServletContext中。
17. String token = UUID.randomUUID().toString(); // 生成Token
19. session.setAttribute("token", token); // 将生成的token放入Session
20. //生成request，来获取客户端的IP
21. HttpServletRequest request = (HttpServletRequest) mc
22. .get("HTTP.REQUEST");
23. System.out.println("request:" + request.getRemoteAddr());
24. }
26. }

@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());   
    }   
  
}  

Java代码

1. @webservice
2. publicclass UserLoginService implements ILoginInfo {
3. @Resource
4. private WebServiceContext wsContext;
5. private MessageContext mc;
6. private HttpSession session;
8. public String UserLoginDao(String token) {
9. mc = wsContext.getMessageContext();
10. session = (HttpSession) ((javax.servlet.ServletContext) mc
11. .get(MessageContext.SERVLET_CONTEXT)).getAttribute("session");
12. System.out.println("Token:" + session.getAttribute("token"));
13. return"Success--->" + token;
14. }
16. }

@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

Xml代码

1. <context-param>
2. <param-name>contextConfigLocation</param-name>
3. <param-value>WEB-INF/beans.xml</param-value>
4. </context-param>
5. <listener>
6. <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
7. </listener>
8. <display-name>cxf</display-name>
9. <servlet>
10. <servlet-name>cxf</servlet-name>
11. <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
12. <load-on-startup>1</load-on-startup>
13. </servlet>
15. <servlet-mapping>
16. <servlet-name>cxf</servlet-name>
17. <url-pattern>/*</url-pattern>
18. </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

Xml代码

1. <importresource="classpath:META-INF/cxf/cxf.xml"/>
2. <importresource="classpath:META-INF/cxf/cxf-extension-soap.xml"/>
3. <importresource="classpath:META-INF/cxf/cxf-servlet.xml"/>
4. <!-- ===============具体服务实例============= -->
6. <beanid="userLoginService"class="com.dyc.impl.UserLoginService"/>
8. <beanid="regirstInfoService"class="com.dyc.impl.RegirstInfoService"/>
11. <!-- ===============对外发布服务============= -->
12. <jaxws:endpointid="loginService"implementor="#userLoginService"
13. address="/LoginService">
14. </jaxws:endpoint>
16. <jaxws:endpointid="regirstService"implementor="#regirstInfoService"
17. address="/RegirstService">
18. </jaxws:endpoint>
