1、pom文件

  4.0.0  com.cun  plus  0.0.1-SNAPSHOT  jar  plus  Demo project for Spring Boot      org.springframework.boot    spring-boot-starter-parent    1.5.14.RELEASE             UTF-8    UTF-8    1.8              org.springframework.boot      spring-boot-starter-web              mysql      mysql-connector-java      runtime              org.springframework.boot      spring-boot-starter-test      test                  com.baomidou      mybatis-plus-boot-starter      2.3                      org.freemarker      freemarker      2.3.28                  com.alibaba      druid-spring-boot-starter      1.1.10                          org.springframework.boot        spring-boot-maven-plugin            

2、创建CodeGenerator.java

package com.cun.plus;import com.baomidou.mybatisplus.enums.IdType;import com.baomidou.mybatisplus.generator.AutoGenerator;import com.baomidou.mybatisplus.generator.config.DataSourceConfig;import com.baomidou.mybatisplus.generator.config.GlobalConfig;import com.baomidou.mybatisplus.generator.config.PackageConfig;import com.baomidou.mybatisplus.generator.config.StrategyConfig;import com.baomidou.mybatisplus.generator.config.rules.DbType;import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;public class CodeGenerator {  public static void main(String[] args) {    //1. 全局配置    GlobalConfig config = new GlobalConfig();    config.setActiveRecord(false) // 是否支持AR模式        .setAuthor("len") // 作者        .setOutputDir(".\\src\\main\\java") // 生成路径        .setFileOverride(true) // 文件覆盖        .setIdType(IdType.AUTO) // 主键策略        .setServiceName("I%sService") // 设置生成的service接口的名字的首字母是否为I        // IUserService        .setBaseResultMap(true)        .setBaseColumnList(true);    //2. 数据源配置    DataSourceConfig dsConfig = new DataSourceConfig();    dsConfig.setDbType(DbType.MYSQL) // 设置数据库类型        .setDriverName("com.mysql.jdbc.Driver")        .setUrl("jdbc:mysql://localhost:3306/mydatab?useSSL=true&verifyServerCertificate=false&allowMultiQueries=true&useUnicode=true&characterEncoding=UTF-8")        .setUsername("root")        .setPassword("lqq74561");    //3. 策略配置    //配置要生成的表的表名    String[] tableName = {"system_power_type","system_admin","company","power_api","power_action","power_action_api","power_action_group","power_admin_group","power_group"};    StrategyConfig stConfig = new StrategyConfig();    stConfig.setCapitalMode(true) //全局大写命名        .setDbColumnUnderline(true) // 指定表名 字段名是否使用下划线        .setNaming(NamingStrategy.underline_to_camel) // 数据库表映射到实体的命名策略        .setTablePrefix("tb_")        .setInclude(tableName); // 生成的表    //4. 包名策略配置    PackageConfig pkConfig = new PackageConfig();    pkConfig.setParent("com.cun.plus")        .setMapper("mapper")        .setService("service")        .setController("controller")        .setEntity("entity")        .setXml("mapper");    //5. 整合配置    AutoGenerator ag = new AutoGenerator();    ag.setGlobalConfig(config)        .setDataSource(dsConfig)        .setStrategy(stConfig)        .setPackageInfo(pkConfig);    //6. 执行    ag.setTemplateEngine(new FreemarkerTemplateEngine());    ag.execute();  }}

3、在application.yml中配置mybatis-plus

#mybatis-plusmybatis-plus: #xml mapper-locations: classpath:/mapper/*Mapper.xml #bean typeAliasesPackage: com.cun.plus.entity global-config:  # 3:"UUID";  id-type: 3  field-strategy: 2  db-column-underline: true  key-generator: com.baomidou.mybatisplus.incrementer.OracleKeyGenerator  logic-delete-value: 1  logic-not-delete-value: 0  sql-injector: com.baomidou.mybatisplus.mapper.LogicSqlInjector configuration:  map-underscore-to-camel-case: true  cache-enabled: false  #JdbcTypeForNull  jdbc-type-for-null: 'null'

4、创建MybatisPlusConfig.java文件

package com.cun.plus.conf;import org.mybatis.spring.annotation.MapperScan;import org.springframework.context.annotation.Configuration;@Configuration@MapperScan("com.cun.plus.mapper")public class MybatisPlusConfig {}

其他

Wrapper：MP内置条件封装器。

Sql分析器：（MybatisPlusConfig.java中）

/** * SQL执行效率插件 */@Bean@Profile({"dev","test"})// 设置 dev test 环境开启public PerformanceInterceptor performanceInterceptor() {  return new PerformanceInterceptor();}
