一.配置相关
iSignature_Cloud_API.lic:
认证文件,这个应该是有过期时间的。过期后可能会显示中间件授权相关提示。
Mypdffileresource.java:
关键实现类,金格操作会调用此处的方法进行操作。
pdfviewer.properties:
这个地方里面有个跨域配置可能需要注意在本地调试时,需配置上本地地址:
2. 如果你集成服务,他们会提供一个jsp后端项目。基本上像什么服务器之类的基本信息都给你了,需要对应改下位置就好,配置文件移动到和springboot的resource下
contorller
@Autowired
private MyPdfFileResource myPdfFileResource;
@RequestMapping(value = "/jingePdf",method = {RequestMethod.GET,RequestMethod.POST})
@ApiOperation("金格请求入口")
public void jingePdf(HttpServletRequest request, HttpServletResponse response) throws IOException, DataException {
request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");
String contentType = request.getContentType();
try {
PdfViewer.execute(request, response,myPdfFileResource);
} catch (Throwable e) {
if (ReqUtil.isStartWithApplicationJson(contentType)) {
JSONObject obj = new JSONObject();
obj.put("status", false);
obj.put("message", "程序异常,请联系管理员!");
response.getWriter().write(obj.toJSONString());
}
}
}
对于spring可以自动注入MyPdfFileResource.
3.前端
前端部分让他们提供一个vue项目。他们有vue的示例
我们要关注的是如何传参数。

<div class="UploadFile-container">
<template v-if="filePath && filePath.length > 0">

代码只是说明使用,结合具体业务封装组件。主要是通过this.open方法传,试过了这个地方没法使用对象传多个参数,看了下源码发现他就是一个string。所以要this.open只能传一个字符串。要么用拼接传过去,要么用json字符串传过去,这里简单使用拼接方式。
后端对应会填充到documentid.具体处理的话你们需要根据自己的规则写。
这是我的,可以参考。

效果
注意:
1.要把jsp的jar打包到自己的后端哪里。请使用maven的,现在我想应该没人还是直接用jar包直接丢的吧,怎么把jar打包一个maven库,请参考如下文章。
将多个jar打包成一个jar_练气期小修士的博客-CSDN博客
2.使用前端的seturl其实就是写自己后端的服务地址。
类似这样的,localhost:8080/api/file/jingePdf 具体就是要访问在pdf接口即可
