转：传智播客—jbpm与OA项目（七） 续一
如继往还需要一个FormDefinitionService和FormDefinitionService，不需要为它们添加任何额外实现直接继承自DaoBase就可以了，因为jbpm也使用hibernate哦！而我们的DaoBase是一个通用的数据库基本操作。
/**
?* 显示自定义表单列表
?*/
public ActionForward list(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response)
??????? throws Exception {
??? // 查询数据列表并将信息添加到request的formDefinitionList属性中
??? List<FormDefinition> formDefinitionList = formDefinitionService.findAll();
??? request.setAttribute("formDefinitionList", formDefinitionList);
??? return mapping.findForward("list"); // list.jsp
/**
?* 添加自定义表单页面
?*/
public ActionForward addUI(ActionMapping mapping, ActionForm form,
??????? HttpServletRequest request, HttpServletResponse response)
??????? throws Exception {
??? // 获取自定义表单需要使用的流程信息
??? List<String> processNameList = processDefinitionService
??????????? .findAllNameList();
??? // 将流程信息添加到request中，用于在页面显示
??? request.setAttribute("processNameList", processNameList);
??? return mapping.findForward("addUI"); // addUI.jsp
/**
?* 添加自定义表单
?*/
public ActionForward add(ActionMapping mapping, ActionForm form,
??????? HttpServletRequest request, HttpServletResponse response)
??????? throws Exception {
??? // 获取表单提单过来的信息
??? FormDefinitionActionForm actionForm = (FormDefinitionActionForm) form;
??? // 将ActionForm中的信息封装到FormDefinition中
??? FormDefinition formDefinition = new FormDefinition();
??? BeanUtils.copyProperties(formDefinition, actionForm);
??? // 下面就是用户自定义的所有表单字段
??? for (int i = 0; i < actionForm.getPropertyNameList().length; i++) {
??????? String name = actionForm.getPropertyNameList()[i];
??????? Class valueType = actionForm.getPropertyValueTypeList()[i];
??????? // 判断字段名称是否有效
??????? if (name != null && name.trim().length() > 0) {
??????????? formDefinition.getFieldDefinitionList().put(name, valueType);
??????? }
??? }
??? // 保存表单定义
??? formDefinitionService.save(formDefinition);
??? return mapping.findForward("toList");
/**
?* 删除自定义表单
?*/
public ActionForward del(ActionMapping mapping, ActionForm form,
??????? HttpServletRequest request, HttpServletResponse response)
??????? throws Exception {
??? // 获取将被删除的表单记录id
??? Long id = Long.parseLong(request.getParameter("id"));
??? formDefinitionService.delete(id);
??? return mapping.findForward("toList");
}
