springboot、mybatisplus框架整合搭建

目录结构
springboot、mybatisplus框架整合搭建

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

  1. 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
  1. 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!");
	}

}
