转:传智播客—jbpm与OA项目(七) 续一

如继往还需要一个FormDefinitionServiceFormDefinitionService,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。

 

DispatchAction

1.表单定义列表

/**

 * 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requestformDefinitionList属性中

    List<FormDefinition> formDefinitionList = formDefinitionService.findAll();

    request.setAttribute("formDefinitionList", formDefinitionList);

    return mapping.findForward("list"); // list.jsp

}

 

2.显示添加表单页面

/**

 * 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

}

 

3.添加表单

/**

 * 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;

    // ActionForm中的信息封装到FormDefinition

    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");

}

 

4.删除表单

/**

 * 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");

}
