我正在尝试从HTML Form向Action类提交未知数字输入,并使用Action类中的request Method(Used ServletActionContext)获取Input参数信息。
但它的投掷
Unexpected Exception caught setting 'xx' on 'class classname Error setting expression 'xx' with value ['yy', ]
由于表单中的输入元素是使用JS动态添加的,因此我无法在Action类中使用getter和setter。
如何处理Action类而没有任何异常?

public class Timeprocess {
public String execute() {
HttpServletRequest request = ServletActionContext.getRequest();
String tt="tt";
String rf="rf";

for(int i=0;i<Integer.parseInt(request.getParameter("taskcount"));i++)

System.out.println("Task Type :"+ request.getParameter(tt+String.valueOf(i)));
System.out.println("Task Type :"+ request.getParameter(rf+String.valueOf(i)));

System.out.println("Task Type :"+ request.getParameter(eff+String.valueOf(i)));

您可以通过在动作配置中覆盖拦截器来控制Struts2的参数填充过程。
/home/mhb11/.virtualenvs/myenv/local/lib/python2.7/site-packages/django/contrib/admin/static//somefile.css
在那里修改location /static/admin/ {
alias /home/mhb11/.virtualenvs/myenv/local/lib/python2.7/site-packages/django/contrib/admin/static/;
}
拦截器的<action name="timesheetprocess" class="com.App.Controller.Timesheet.Timeprocess"
method="execute">
<interceptor-ref name="defaultStack">
<param name="params.excludeParams">.*</param>
</interceptor-ref>
<result name="success">Time.jsp</result>
</action>
属性,以排除通过OGNL处理的所有参数。
您不应以这种方式获得任何异常,但请确保已配置excludeParams
params
它应该从输出中删除不必要的警告。如果日志中仍然出现任何警告或异常,则应配置日志记录框架以禁止输出中的这些警告或错误。
