springboot、mybatisplus框架整合搭建

springboot、mybatisplus框架整合搭建

目录结构

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

 <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus</artifactId>
            <version>3.1.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity-engine-core</artifactId>
            <version>2.0</version>
        </dependency>
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>

            <scope>runtime</scope>
            <version>8.0.13</version>
        </dependency>

3. 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

4. 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!");
	}

}
