通用Mapper的使用（代码生成器）_java

一、添加依赖

 
        
            org.projectlombok
            lombok
            1.18.8
            provided
        
        
            tk.mybatis
            mapper-spring-boot-starter
            2.1.5

二、添加通用代码生成器插件


                org.mybatis.generator
                mybatis-generator-maven-plugin
                1.3.6
                
                    
                        src/main/resources/generator/generatorConfig.xml
                    
                    true
                    true
                
                
                    
                        mysql
                        mysql-connector-java
                        8.0.16
                    
                    
                        tk.mybatis
                        mapper
                        4.1.5

三、添加数据库配置属性

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/hello?serverTimezone=UTC
    username: root
    password: wcc@090208%
    #MySQL5.7.x及8.0以下   driver-class-name: com.mysql.jdbc.Driver
    #MySQL8.x    driver-class-name: com.mysql.cj.jdbc.Driver
    driver-class-name: com.mysql.cj.jdbc.Driver

四、配置通用mapper

在resource中创建文件夹generator及配置文件config.properties和generatorConfig.xml

config.properties

#jdbc.driverClass=com.mysql.cj.jdbc.Driver
jdbc.driverClass=com.mysql.cj.jdbc.Driver
#jdbc.url=jdbc:mysql://localhost:3306/hello?serverTimezone=Asia/Shanghai
jdbc.url=jdbc:mysql://localhost:3306/hello?serverTimezone=UTC
jdbc.user=root
jdbc.password=wcc@090208%

# 表名
tableName=user

generatorConfig.xml
