关于用jsp启动Spring

spring spring-boot jsp

关于用jsp启动Spring,spring,spring-boot,jsp,controller,pom.xml,Spring,Spring Boot,Jsp,Controller,Pom.xml,我不熟悉java和spring boot。现在我正在做一个基于Spring boot、security和MVC视频的项目。我正在使用MySql数据库。我已经成功地完成了，使用邮递员以下的视频。我想用jsp文件做这个项目。但我不知道怎么做。我遇到了大约500个错误（异常处理模板“索引”：错误解析模板[index]，模板可能不存在或任何配置的模板解析程序都无法访问）。请任何人给我任何解决方案 @RestController @RequestMapping("/api/auth")

这是我的jsp

您的“索引”方法似乎很好

但我认为您的问题来自于使用@RestController而不是@Controller

如果我没有记错SpringMVC是如何工作的，当在@Controller中使用返回字符串的方法时，spring将查找一个视图，返回的字符串作为它的ID。如果找到，它将转发到该视图

@再
