Struts hasFieldErrors() and hasActionMessages

由 早过忘川 提交于 2019-12-09 23:00:19
首先请看如下代码： <s: if test= "hasFieldErrors()" > <s:iterator value= "fieldErrors" > <s:iterator value= "value" > <script language= "JavaScript" > alert( '<s:property/>' ); </script> </s:iterator> </s:iterator> </s: if > [java] view plain copy print ? <s: if test= "hasFieldErrors()" > <s:iterator value= "fieldErrors" > <s:iterator value= "value" > <script language= "JavaScript" > alert( '<s:property/>' ); </script> </s:iterator> </s:iterator> </s: if > 这样当有field错误,就会弹出错误提示！当然不alert的话 也可以在外面之间套上div,控制输出格式 但问题来了 如果有多个field错误 就会不断地弹出消息窗口 我想把所有的错误消息全部显示在一个对话框中 每条错误消息占一行 怎么才能做到呢？ 经过很长时间的摸索 问题终于给解决了

How to secure BIRT Report Viewer

由 不羁岁月 提交于 2019-12-09 13:21:26
问题 I need to implement authentication of user for birt report viewer while opening the reports, so that we should not be able to run the report and user authentication should also be done before opening the report. 回答1: As Iswanto San already mentioned in his comment - I would use Spring Security as well. But it really depends on your skill set - and what you are deploying your viewer to. If you use Tomcat - you can create a simple form authentication by following this step-by-step guide from

<html:errors> struts tutorial or example

问题 I'm trying to make a login page in Struts. The idea is to validate if the user exists, etc, and then if there is an error, return to the login page with the errors in red (the typical login or any form page validation). I would like to know if someone knows an errors management tutorial in Struts. I'm looking specially for a tutorial (or example) of the <html:errors> tag, which I think would solve my problem. 回答1: Here's a quick summary. You have an ActionForm class, say MyForm : <form-bean

Difference between Interceptors and Filters - Is this right?

由 自作多情 提交于 2019-12-09 04:42:30
问题 I'm researching this so that I can respond better in interviews. I've been searching around for a clear and concise answer. So far, and by all means correct me if I am wrong or lacking in detail: Filters are part of the Servlet API, Interceptors are Struts 2. (Seems obvious though) The Interceptor stack fires on requests in a configured package while filters only apply to their mapped URLs. Interceptors can be configured to execute or not depending on specific target action methods via

struts2 adding interceptors in struts.xml for all action class

由 荒凉一梦 提交于 2019-12-09 00:34:33
问题 I've used the Struts 2 framework and I have created a web application which has a Login Page. I have three different Action classes named Action1 , Action2 , Action3 , and different views for JSP pages which are rendered by running some business logic in the Action classes. Now, I want to check whether a user has logged in before the Action class carries out processing. So, I created an interceptor below that works fine. public String intercept(ActionInvocation invocation) throws Exception {

How can I refactor HTML markup out of my property files?

问题 I've recently inherited a internationalized and text-heavy Struts 1.1 web application. Many of the JSP files look like: <p> <bean:message key="alert" /> </p> and the properties files look like: messages.properties alert=Please update your <a href="/address.do">address</a> and <a href="/contact.do">contact information</a>. with the appropriate translations in N other languages (messages_fr.properties, etc). Problems: DRY violation - I have N references to my Struts action URLs instead of 1,
