I'm creating a database record edit form using Struts. <s:select id="status" name="newRecord.status" list="statusTypes" listKey="id" listValue="description" label="Status:" value="" /><br /> Example list: Status' list: 1 Open 2 Closed 3 Pending I want to set a default value on the status field as the current status which is stored in record.status which contains the string representation e.g. "Open" . If I set value="%{record.status} it doesn't work because that's not any list key. Is there a way I can set this value when I only have the string representation to work with? Or should I redesign

We are using Struts 2 validators @FieldExpressionValidator and @ExpressionValidator . These validators check on OGNL expression. There are lots of cases where we deal with Strings in these expressions. expression="(captcha=='' && captcha== null || ....) We find it is very useful if we can use StringUtils ( isEmpty ,trimToEmpty,... ) here. As we set the struts.ognl.allowStaticMethodAccess to false, for security issues, we tried to solve it by adding this getter to action public StringUtils getStringUtils(){ return new StringUtils(); } and then stringUtils.isEmpty(captcha) in the expression. But

在 mybatis 的映射 xml 文件调用 java 类的方法：使用的是 OGNL 表达式，表达式格式为： ${@prefix@methodName(传递参数名称)} 因为我比较懒,每次都要手动给 createBy 赋值，想有没有一种简单的方法,百度一番,搜到了 mybatis 还可以调用 java 类的方法 调用saveDoc方法的时候，才会去调用SecurityUtils类的getUserId方法 <insert id="saveDoc"> INSERT INTO `doc`( `phone`, `create_by`, `create_time`) VALUES ( '1541234512','${@com.xxx.common.utils.SecurityUtils@getUserId()}', now()); </insert> 注意: 方法必须为 静态 方法 MyBatis常用OGNL表达式 e1 or e2 e1 and e2 e1 == e2,e1 eq e2 e1 != e2,e1 neq e2 e1 lt e2：小于 e1 lte e2：小于等于，其他gt（大于）,gte（大于等于） e1 in e2 e1 not in e2 e1 + e2,e1 * e2,e1/e2,e1 - e2,e1%e2 !e,not e：非，求反 e.method(args

I want list of items to be displayed along with each having a blank textfield to fill amount on my JSP page and once I fill the required items amount, I will submit. I have ExampleAction class as below, where I have populate() method which I fire first so that items are filled. I fire URL : http://localhost:8084/WebExample/populate.action. Same ExampleAction has execute mtd which I call on SUBMIT button action from JSP page. But my problem is in execute method, I am unable to get the objects in list i.e. exList. Is this because an instance of the action class is associated with just one

我之前虽然会用，但是一直分不清彼此之间有什么区别，所以查找资料，将它们进行整合区分，加深了解， 一 介绍 1．Struts2的作用 Struts2标签库提供了主题、模板支持，极大地简化了视图页面的编写，而且，struts2的主题、模板都提供了很好的扩展性。实现了更好的代码复用。Struts2允许在页面中使用自定义组件，这完全能满足项目中页面显示复杂，多变的需求。 Struts2的标签库有一个巨大的改进之处，struts2标签库的标签不依赖于任何表现层技术，也就是说strtus2提供了大部分标签，可以在各种表现技术中使用。包括最常用的jsp页面，也可以说Velocity和FreeMarker等模板技术中的使用 2．Struts2分类 （1）UI标签：（User Interface, 用户界面）标签，主要用于生成HTML元素标签，UI标签又可分为表单标签非表单标签 （2）非UI标签，主要用于数据访问，逻辑控制等的标签。非UI标签可分为流程控制标签（包括用于实现分支、循环等流程控制的标签）和数据访问标签（主要包括用户输出ValueStack中的值，完成国际化等功能的） （3）ajax标签 3．Struts2标签使用前的准备： （1）在要使用标签的jsp页面引入标签库： <%@ taglib uri="/struts-tags" prefix="s"%> （2）在web
