拦截器调用后未填充Struts 2动作变量。 [英] Struts 2 action variables not populated after interceptor's invocation.invoke()
本文介绍了拦截器调用后未填充Struts 2动作变量。的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我的问题是,在使用invocation.invoke从拦截器中触发了动作的变量后,该变量没有被填充。我所知道的是,在使用拦截器之前,它可以正常工作(我从.jsp提交了一个表单,然后调用了一个动作,并且填充了每个变量)
My Problem is that the action's variables are not being populated after it is triggered from the interceptor using invocation.invoke. What i know is that before using an interceptor , it worked properly (From a .jsp i submitted a form and an action is called and every variable was populated)
Interceptor类:
Interceptor class:
public String intercept(ActionInvocation invocation) throws Exception {
final ActionContext context = invocation.getInvocationContext();
HttpServletRequest request = (HttpServletRequest) context.get(HTTP_REQUEST);
HttpSession session = request.getSession(true);
Object user = session.getAttribute(Constants.USER_HANDLE);
if (user == null) {
String signUp = request.getParameter(Constants.SIGN_UP);
if (!StringUtils.isBlank(loginAttempt)) {
if (processLoginAttempt(request, session)) {
return "login-success";
}
} else if (!StringUtils.isBlank(signUp)) {
return invocation.invoke();
}
return "login";
} else {
return invocation.invoke();
}
}
Struts XML文件:
Struts XML file :
<package name="defaultPackage" extends="struts-default">
<interceptors>
<interceptor name="login" class="com.spiddan.LoginInterceptor" />
<interceptor-stack name="defaultStack">
<interceptor-ref name="login"/>
</interceptor-stack>
</interceptors>
<default-interceptor-ref name="defaultStack"/>
<default-action-ref name="index"/>
<global-results>
<result name="login" type="redirect">/logIn.jsp</result>
<result name="login-success" type="redirect">index</result>
</global-results>
<action name="addUserAction" class="com.spiddan.action.UserAction" method="addUser">
<result name="input">/logIn.jsp</result>
<result name="success">/index.jsp</result>
<result name="error">/error.jsp</result>
</action>
动作类别:
public class UserAction extends ActionSupport implements ModelDriven {
private User user;
private int tempGender;
private String confirmPassword;
private UserDAO userDAO;
private PasswordEncrypter passwordEncrypter;
public Object getModel() {
return getUser();
}
public String addUser() throws Exception {
}
//Getter and setters ect
推荐答案
您仅在代码中指定了自定义拦截器,并排除了其他所有拦截器Struts2默认拦截器。改为尝试以下操作:
You've specified only your custom interceptor in your code and have excluded all the other Struts2 default interceptors. Try this instead:
<interceptors>
<interceptor name="login" class="com.spiddan.LoginInterceptor" />
<interceptor-stack name="defaultStackModified"> <!-- name doesn't override existing defaultStack-->
<interceptor-ref name="defaultStack"/> <!-- include the defaultStack this way-->
<interceptor-ref name="login"/>
</interceptor-stack>
</interceptors>
