struts2拦截器 获得请求方法名+获得请求参数
SSI框架为基础开发的，hulian平台
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
loginMain,loginTop,loginSwitch,loginRight,login,leftMenuShow, queryCityList,queryInOrOutAreaList,queryDistricts /errorPrivPage.jsp /jsp/phone/xxxx.jsp /jsp/phone/login/trunToLogin.jsp /errorPage.jsp ${successPath} ${errorPath} ${inputPath} ${redirectActionPath} ${chainPath} ${redirectPath} application/vnd.ms-excel inputStream filename="${printFileName}" 1024
2.Action这么写
/**
* 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;
}
}3.struts2拦截器

@SuppressWarnings("serial")
@Component( "PrivInterceptor" )
@Scope("prototype")
public class PrivInterceptor extends MethodFilterInterceptor{
@Resource(name = "EmployeeService")
private EmployeeService empSafeService;//工号安全Service
@Resource(name="EmployeeRoleService")
private EmployeeRoleService empRoleService;

System.out.println("执行到拦截器里。。。。");
ActionContext act = invocation.getInvocationContext();
//获得session
Map session = invocation.getInvocationContext().getSession();
TEmployeeInfo sessionInfo = (TEmployeeInfo) session.get("user");
String employee_id="";
/**

*/
try
{
employee_id = sessionInfo.getEmployeeId();
}
catch( NullPointerException e )
{
act.put("message", "Session过期，请重新登录！");
return "loginPage";
}
/*=========================================================单点登录判断============================================*/
HashMap map = (HashMap) ServletActionContext.getServletContext().getAttribute("userList");
String sessionID_User = map.get( employee_id ); //登录用户session的ID
String sessionID_Now = ServletActionContext.getRequest().getSession().getId(); //当前session的ID
if( ! sessionID_User.trim().equals(sessionID_Now) )
{
act.put("message", "此账号已登录！");
return "privError";
}
/*=========================================================单点登录判断============================================*/
/**
* 二、登录成功后，根据URL进行权限判断
*/
if( !"".equals(employee_id.trim()) && null!=employee_id )
{
/**
* 2.1判断工号登录后，业务密码是否为123456，是跳转到商户安全设置，修改业务密码
*/
/*TEmployeeSafe empSafe = empSafeService.queryEmployeSafe(employee_id);
if( null!=empSafe )
{
String MD5password = KeyedDigestMD5.getKeyedDigest("123456","").toUpperCase();//获得123456的MD5值
String employeePass = empSafe.getEmployeePass();//获得登录密码
String employeePass2 = empSafe.getEmployeePass2();//获得工号业务密码
if( MD5password.equals(employeePass) || MD5password.equals(employeePass2) )
{
act.put("message", "欢迎使用本系统，您的登录密码、业务密码过于简单，请修改！");
return "updateEmpPassword";
}
}*/
/**
* 2.2截取请求URL
*/
HttpServletRequest request = ServletActionContext.getRequest();
String currentURL = request.getRequestURI();
String targetURL = "";
if( -1 != currentURL.indexOf("?") )//普通 输出：
16:05:35,813 INFO [STDOUT] ============Priv_queryPriv
16:05:35,813 INFO [STDOUT] ============zh_CN
16:05:35,813 INFO [STDOUT] ============{}
16:05:35,813 INFO [STDOUT] 执行到拦截器里。。。。
16:05:35,813 INFO [STDOUT] 请求路径URL:/Priv_queryPriv

struts2 拦截拦截器怎么样获得action 后面的参数 例如 login.action? user.user_name='aaaaa'
我想获得到action 后面的参数再做判断，请问怎么样获得呢
问题补充：
我想在拦截器里面得到传入的user.user_name
最佳答案
先在拦截器intercept（）方法中获取parameters对象：
Map paramMap = invocation.getInvocationContext().getParameters();
然后用parameters对象获取参数(是一个字符串数组)：
String[] names = (String[]) paramMap.get("user.user_name");
String username=names[0];
