1. interceptor 调用Spring容器中的bean

  在interceptor中常有需要调用Spring Bean的需要,其实很简单和Struts2的Action一样配置即可.

Spring中的配置

      4         
      5         
      6         
      
       7             
       
        *Modify,*Delete
       8         
      9     
     

Struts2中的配置

      3             
       5         
     

2. 如何获得当前Action名字　　

public String intercept(ActionInvocation aInvocation) throws Exception {　　// 获取请求的action名称　　String actionName = aInvocation.getInvocationContext().getName();

　　 　　//获取参数集合 　　Map parameters = aInvocation.getInvocationContext().getParameters();

　　 ....}

3. 方法拦截器黑白名单可以使用通配符

    拦截器代码:

　　

package xx.interceptor;import xx.action.ProjectAction;import xx.action.SysDefectAction;import xx.po.Project;import xx.po.SysDefect;import xx.po.User;import xx.service.IProjectService;import xx.service.ISysDefectService;import com.opensymphony.xwork2.Action;import com.opensymphony.xwork2.ActionContext;import com.opensymphony.xwork2.ActionInvocation;import com.opensymphony.xwork2.interceptor.MethodFilterInterceptor;import java.util.List;public class OperationInterceptor extends MethodFilterInterceptor {    private ISysDefectService defectService;    private IProjectService projectService;      protected String doIntercept(ActionInvocation actionInvocation) throws Exception {        boolean hasAuth = false;        String cunrrentId = "";        Object currentActon =actionInvocation.getAction();        ActionContext actionContext = actionInvocation.getInvocationContext();        User currentUser = (User)actionContext.getSession().get("currentUser");        if(currentUser == null                || currentUser.getEmployer()==null                || currentUser.getGroup() == null                || currentUser.getEmployer().getEmpId()+""==null        )        {            return Action.LOGIN;        }        //获取当前用户的epmId        String empId = currentUser.getEmployer().getEmpId() + "";        if(currentActon instanceof ProjectAction){            //是否第二次检查权限            List
     
       projectList = currentUser.getProjectList();            if (projectList==null || projectList.size()<1){                ProjectAction projectAction = (ProjectAction)currentActon;                cunrrentId = projectAction.getProjId();                projectList =  projectService.getProjectsByEmpId(empId);            }            //如果获取列表失败,则提示无权限            if(projectList==null || projectList.size()<1){                return "deny";            }else {                currentUser.setProjectList(projectList);            }            for(Project project:projectList){                if(cunrrentId.equals(project.getProjId()+"")){                    hasAuth = true;                }            }            if(hasAuth){                return actionInvocation.invoke();            }        }else if(currentActon instanceof SysDefectAction){            SysDefectAction sysDefectAction = (SysDefectAction)currentActon;            List
      
        sysDefectList =  defectService.getSysDefectsByEmpId(empId);            if(sysDefectList==null || sysDefectList.size()<1){                return "deny";            }else {                currentUser.setSysDefectList(sysDefectList);            }            for(SysDefect sysDefect:sysDefectList){                if(cunrrentId.equals(sysDefect.getDefId()+"")){                    hasAuth = true;                 }            }            if(hasAuth){                return actionInvocation.invoke();            }        }        return "deny";  //To change body of implemented methods use File | Settings | File Templates.    }    public ISysDefectService getDefectService() {        return defectService;    }    public void setDefectService(ISysDefectService defectService) {        this.defectService = defectService;    }    public IProjectService getProjectService() {        return projectService;    }    public void setProjectService(IProjectService projectService) {        this.projectService = projectService;    }}
