本篇文章给大家带来的内容是关于springboot2.0整合同时支持jsp+html跳转的方法介绍（附代码），有一定的参考价值，有需要的朋友可以参考一下，希望对你有所帮助。
说明一下 。整合会遇到的问题，
1、pom.xml文件同时放入thymeleaf 架包和jsp支持后， springboot的return模版会默认跳转到html ，
那怕是你并没有配置thymeleaf的属性
解决方案， 使用getRequestDispatcher方法来跳转到jsp页面， 就同时支持html和jsp了
立即学习“前端免费学习笔记（深入）”；
request.getRequestDispatcher("/WEB-INF/views/testJsp.jsp").forward(request, response);
2、另外 使用getRequestDispatcher跳转到html页面的时候，thymeleaf 模版接收参数可能会出现问题。
解决方案1：html放弃使用thymeleaf 模版，然后在页面主动请求接口数据(AJAX POST等)
解决方案2：html继续使用thymeleaf 模版，用return模版 返回来跳转页面

以上就完了。
另外附加一个return 模版的java代码配置， 可以配置return模版的优先级，后面的文件格式，当然只能用getRequestDispatcher来跳转了
在启动类中添加，另外，配置文件参数和代码可重复 但是代码优先于配置文件。
