本文介绍了如何在Spring框架中配置Thymeleaf并集成JSP页面，包括配置缓存、视图解析器、数据源及MyBatis映射文件的位置。此外还展示了如何通过Controller处理请求并返回数据。

yaml配置

spring:
  #添加Thymeleaf配置，除了cache在项目没上线前建议关了，其它配置都可以不用配的，本博客只是列举一下有这些配置
  thymeleaf:
    cache: false # 开发时关闭缓存,不然没法看到实时页面
    mode: HTML # 用非严格的 HTML
    encoding: UTF-8
    servlet:
      content-type: text/html

  datasource:
    url: jdbc:mysql://localhost:3306/testyxt?useUnicode=true&characterEncoding=UTF-8&useSSL=false
    username: root
    password: root
    driver-class-name: com.mysql.cj.jdbc.Driver
  mvc:
    view:
      # 页面默认前缀目录
      prefix: /
      # 响应页面默认后缀
      suffix: .jsp

mybatis:
  mapper-locations: classpath:mapper/*Mapper.xml

import javax.annotation.Resource;
import java.util.List;

@Controller //等效于 @Controller加上 @ResponseBody
@RequestMapping("/user")
public class HelloController {
    @Resource
    private UserService userService;
    @RequestMapping("find1")
    @ResponseBody
    public String get(){
//       String list11="22";
//        modelAndView.setViewName("index");
//        return modelAndView;
        return "/main";
    }

    @RequestMapping("find")
    @ResponseBody
    public List<User> findAll(){
        return  userService.findAll();
    }
