struts2拦截器 获得请求方法名+获得请求参数

struts2拦截器里如何知道你请求的是那个方法

使用:invocation.getInvocationContext().getName(); //输出Priv_queryPriv,这正是我访问的Action中的方法。

 

1.struts.xml中这么定义的

Xml代码  


<struts>  

    <!-- character filter -->  

    <constant name="struts.i18n.encoding" value="utf-8" />  

    <constant name="struts.multipart.saveDir" value="/tmp" />  

    <constant name="struts.multipart.maxSize" value="1000000000" />  

    <!-- CONFIG Global Exception -->  

      

    <package name="basePriv" extends="struts-default">  

        <interceptors>  

            <interceptor name="myPrivInterceptor" class="PrivInterceptor"/>  

            <interceptor-stack name="b2cplatPrivInterceptor">  

                <interceptor-ref name="myPrivInterceptor">  

                    <param name="includeMethods"></param>  

                    <param name="excludeMethods">  

                        loginMain,loginTop,loginSwitch,loginRight,login,leftMenuShow,  

                        queryCityList,queryInOrOutAreaList,queryDistricts  

                    </param>  

                </interceptor-ref>  

                <interceptor-ref name="defaultStack"/>  

            </interceptor-stack>  

        </interceptors>  

          

        <default-interceptor-ref name="b2cplatPrivInterceptor"/>  

          

        <global-results>  

            <result name="privError">/errorPrivPage.jsp</result>  

            <result name="updateEmpPassword">/jsp/phone/xxxx.jsp</result>  

            <result name="loginPage" type="redirect">/jsp/phone/login/trunToLogin.jsp</result>  

        </global-results>  

          

        <global-exception-mappings>  

            <exception-mapping result="error" exception="java.lang.Exception">/errorPage.jsp  

            </exception-mapping>  

        </global-exception-mappings>  

    </package>  

      

      

<package name="managerPlatform" extends="basePriv" namespace="/">  

    <action name="*_*" class="{1}Action" method="{2}">  

        <result name="success">${successPath}</result>  

        <result name="error">${errorPath}</result>  

        <result name="input">${inputPath}</result>  

        <result name="redirectAction" type="redirectAction">${redirectActionPath}</result>  

        <result name="doChain" type="chain">${chainPath}</result>  

        <result name="redirect" type="redirect">${redirectPath}</result>  

        <result name="print" type="stream">  

            <param name="contentType">application/vnd.ms-excel</param>  

            <param name="inputName">inputStream</param>  

            <param name="contentDisposition">filename="${printFileName}"</param>  

            <param name="bufferSize">1024</param>  

        </result>  

    </action>  

</package>  

          

</struts>  

 2.Action这么写

Java代码  


/** 

 * 权限信息控制 

 * @author  ken 

 * @date 2011-9-13 下午15:00:46 

 */  

@Scope("prototype")  

@Controller("PrivAction")  

public class PrivAction extends BaseAction{  

  

    private static final long serialVersionUID = 1L;  

    static final Logger log = Logger.getLogger(PrivAction.class);  

      

    @Autowired  

    private PrivService privService;  

      

    /* 权限模型 */  

    private TEmployeePriv employeePriv;  

      

    /** 

     * 权限查询 

     * @return 

     */  

    public String queryPriv(){  

        if(employeePriv==null){  

            employeePriv = new TEmployeePriv();  

            successPath = "/jsp/phone/priv/priv/privList.jsp";  

            return SUCCESS;  

        }  

        try {  

            entitys = this.privService.queryAllPriv(employeePriv);  

        } catch (Exception e) {  

            log.error("",e);  

        }  

          

        successPath = "/jsp/phone/priv/priv/privList.jsp?flag=true";  

        return SUCCESS;  

    }  

}
