最近一直在练习SpringBoot,但是呢,由于习惯使用了SpringMVC+jsp开发项目,所以页面希望用jsp来实现,但是springBoot默认不支持jsp,而是使用自己家族里面的模板技术,所以如果我们需要使用jsp,那需要利用springBoot整合jsp,接下来就简单的整合下JSP,虽然官方并不推荐......
本实例Github地址10-jsp
注意:其中webapp为自己建的目录,包括WEB-INF、jsp、hello.jsp、web.xml都是自己建的

这个应该就很熟悉了

到这里呢,基本就算是完成了,下边要特别注意运行方式,否则会一直404,看到很多小伙伴都是错在这里.......
如上图所示,要使用maven projects里的spring-boot:run方式运行,运行成功如下图所示:
成功之后访问下写好的jsp页面:
ok,简单的整合jsp完毕~
