通过https://start.spring.io创建spingboot项目并导入idea
maven添加mybatisplus、spring、mysql依赖

com.baomidou mybatis-plus 3.1.0 org.apache.velocity velocity-engine-core 2.0 com.baomidou mybatis-plus-boot-starter 3.0.7.1 com.baomidou mybatis-plus-generator 3.0.7.1 org.freemarker freemarker 2.3.23 mysql mysql-connector-java >runtime 8.0.13

application.yml配置mybatisplus配置和数据库配置

#MybatisPlus配置 mybatis-plus: mapper-locations: classpath*:/mapping/**/*.xml type-aliases-package: com.love.entity type-aliases-super-type: java.lang.Object server: port: 8081 ##数据库url spring: datasource: url: jdbc:mysql://127.0.0.1:3306/****?characterEncoding=utf8&useSSL=false username: *** password: *** driver-class-name: com.mysql.cj.jdbc.Driver

主函数配置注解

@SpringBootApplication(scanBasePackages = {"com.dkd.*"}) @EnableCaching @MapperScan("com.dkd.mapper")// 指定mapper public class BootShiroApplication { public static void main(String[] args) { SpringApplication.run(BootShiroApplication.class, args); System.out.println("success!"); }}
