一、开发环境
IntelliJ IDEA 2019.1.2 x64
jdk8
SpringBoot版本：2.3.4.RELEASE
水晶报表依赖版本：CR4ERL26_0-80004572
二、搭建SpringBoot并访问Jsp
1创建SpringBooot项目
pom.xml

2创建webapp文件夹
D:\workspace\idea\SpringBootCrystalReportsJspDemo\src\main\webapp\WEB-INF\web.xml
D:\workspace\idea\SpringBootCrystalReportsJspDemo\src\main\webapp
3创建jsp文件
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>首页</h1>
</body>
</html>4添加controller
@Controller
public class DemoController {
@RequestMapping("/index")
public String hello(Model m) {
m.addAttribute("now", DateFormat.getDateTimeInstance().format(new Date()));
//视图重定向index.jsp
return "index";
}
}5修改配置文件application.properties
spring.mvc.view.prefix=/
spring.mvc.view.suffix=.jsp6确认项目结构
如果不把webapp设置ResourceFolders中，找不到jsp文件。
7项目目录图示以及测试
三、SpringBoot项目中加入水晶报表组件
1下载水晶报表CR4ERL26_0-80004572
链接地址
https://origin.softwaredownloads.sap.com/public/site/index.html
2添加jar包到WEB-INF/lib目录并引入到项目
3拷贝crystalreportviewers和template目录中的CRConfig.xml
- crystalreportviewers需要该名称crystalreportviewers120
- 移动crystal-tags-reportviewer.tld到WEB-INF目录
- CRConfig.xml放在webapp目录下
位置如下图
四、测试
1创建空报表测试
test.rpt 的创建方法自行百度或者参考博客https://blog.csdn.net/cs373616511/article/details/109269674
