本文链接：https://blog.youkuaiyun.com/zhaokai621/article/details/120698004

该博客详细介绍了如何在Spring Boot项目中集成Thymeleaf模板引擎、MyBatis、Druid数据源、MySQL数据库、Redis缓存、JWT令牌认证以及PageHelper分页助手。还展示了配置application.yml文件，以及MyBatis的配置文件mybatis-config.xml的编写。此外，提到了资源过滤、MyBatis自动生成代码插件的使用，并引入了热部署和日志管理的相关依赖。

2.创建application.yml

server:
  port: 8081
#整合mybatis（实体类别名）
mybatis:
  type-aliases-package: com.spring.pojo
  mapper-locations: classpath:mapper/*.xml #mapper路径
  config-location: classpath:mybatis/mybatis-config.xml #配置一些mybatis属性

3.resource目录下创建mapper和mybatis文件夹，mapper放xxmapper，

mybatis下创建mybatis-config.xml文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
	
	<settings>
		<setting name="cacheEnabled"             value="true" />  <!-- 全局映射器启用缓存 -->
		<setting name="useGeneratedKeys"         value="true" />  <!-- 允许 JDBC 支持自动生成主键 -->
		<setting name="defaultExecutorType"      value="REUSE" /> <!-- 配置默认的执行器 -->
		<setting name="logImpl"                  value="SLF4J" /> <!-- 指定 MyBatis 所用日志的具体实现 -->
		<!-- <setting name="mapUnderscoreToCamelCase" value="true"/>  驼峰式命名 -->
	</settings>
	
</configuration>
