泛微OA-E9与第三方系统集成开发企业级实战记录（八）

说明：

今天的实战记录要实现的是：金蝶ERP单据抛到OA审批，OA审批结束后回写审批状态。

实现思路：

1）编写2个自定义类文件（一个是传递审批通过的类文件，一个是传递审批不通过的类文件），类一定要继承BaseBean类或者实现Action接口，并在类中重写execute方法。在execute方法中发送Post请求调用金蝶提供的回写审批状态的接口。

2）将编译后的class文件（源文件也可以，重启后会自动编译成class文件）放到weaver/ecology/classbean目录下，重启服务。

3）配置附加操作，在流程节点"同意归档"节点点击"节点前附加操作"，将传递审批通过的类路径配置上去；在流程节点"驳回归档"节点点击"节点前附加操作"，将传递审批不通过的类路径配置上去。

实现过程：

1）新建传递审批通过的自定义类文件

    BufferedReader in = null;
    String result = "";
    try {
      URL realUrl = new URL(url);
      HttpURLConnection conn = null;

      conn = (HttpURLConnection)realUrl.openConnection();

      conn.setRequestMethod("POST");

      conn.setDoInput(true);

      conn.setRequestProperty("accept", "*/*");
      conn.setRequestProperty("connection", "Keep-Alive");

      out.flush();

      in = new BufferedReader(new InputStreamReader(conn.getInputStream(), "UTF-8"));
      String line;
      while ((line = in.readLine()) != null)
      {

          in.close();
      }
      catch (IOException ex) {
        ex.printStackTrace();

      }
      catch (IOException ex) {
        ex.printStackTrace();
      }
    }
    return result;
  }
}

3）将代码文件放到OA服务器

根据代码文件里的包路径：package weaver.interfaces.workflow;

将编译后的class文件或者java源文件放到如下目录：weaver/ecology/classbean/weaver/interfaces/workflow

重启OA应用服务

4）配置节点前附加操作

将审批通过的代码类路径配置到"同意归档"，将审批不通过的代码类路径配置到"驳回归档"节点的"节点前附加操作"，类路径为包路径+类名称，示例如下：

审批通过的类路径：weaver.interfaces.workflow.AgreeAction

审批不通过的类路径：weaver.interfaces.workflow.RejectAction
