显示图片的步骤

  1. 在service层，根据deploymentid和图片的路径获取到一个输入流，也就是说service层的该方法应该返回一个inputStream。
  2. 在action层，有一个属性：inputStream，service层的方法的返回值应该赋值给inputStream。
  3. 在页面上利用window.open打开一个窗口，让输出流流入这个窗口中。

下载模板经过的步骤

  1. 根据ftid查找到formTemplate对象
  2. 根据该对象查找到url
  3. 根据url创建一个FileInputStream
  4. 在action类中，有一个属性：inputStream，把上面步骤得到的返回值赋值给action的inputStream。
  5. 在struts2的配置文件中，结果集类型为”stream”，设置下载文件输入流参数，fileName来自map栈。

发起申请和审批处理的需求分析

当启动流程实例的时候 ，把form对象放入流程变量中。

审批处理中，该登录人正在审批处理的表单：

登录人—->当前登录人正在执行的任务—->遍历每一个任务—->task—->executionId,”form”—->从当前流程实例中把form提取出来。

步骤分析：

发起申请

表单模板的列表页面

提交申请页面

提交：

  1. 完成上传表单的功能

    需要一个参数：File 该参数从action中可以传递过来

  2. 在form表中插入一行数据

    applicator：申请人 从session中可以获取到 applicateTime：申请时间 就是当前时间

    state：审批中 ftid：表单模板id

    piid：该值只能在启动完流程实例才能赋

  3. 关于工作流

    1. 启动流程实例

      根据pdkey启动流程实例，在启动流程实例的时候可以返回一个pi—->piid

      当启动完流程实例以后可以重新给form对象的piid赋值

    2. 完成请假申请的任务

      需要一个”taskId”

      pi—->piid—->唯一的一个任务—->taskId

发起申请管理
