MyBatisPlus逆向工程
MyBatisPlus逆向工程
一、创建Springboot工程
二、引入pom依赖

三、配置数据库连接（application.properties）
# 应用名称
spring.application.name=TestMybatisPlus
#设置开发环境
spring.profiles.active=dev
#数据库连接配置
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/maomao?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8&useSSL=false
spring.datasource.username=mao
spring.datasource.password=123
#日志配置
mybatis-plus.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl
#配置逻辑删除
mybatis-plus.global-config.db-config.logic-delete-value=1
mybatis-plus.global-config.db-config.logic-not-delete-value=0
四、配置插件注册(MyBatisPlusConfig.java)
package com.mao.testmybatisplus.config;
import com.baomidou.mybatisplus.core.injector.ISqlInjector;
import com.baomidou.mybatisplus.extension.injector.LogicSqlInjector;
import com.baomidou.mybatisplus.extension.plugins.OptimisticLockerInterceptor;
import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;
import com.baomidou.mybatisplus.extension.plugins.PerformanceInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Profile;
public class MyBatisPlusConfig {
//注册乐观锁插件
@Bean
public OptimisticLockerInterceptor optimisticLockerInterceptor() {
return new OptimisticLockerInterceptor();
}
//注册分页插件
@Bean
public PaginationInterceptor paginationInterceptor() {
PaginationInterceptor paginationInterceptor = new PaginationInterceptor();
// 设置请求的页面大于最大页后操作， true调回到首页，false 继续请求 默认false
// paginationInterceptor.setOverflow(false);
// 设置最大单页限制数量，默认 500 条，-1 不受限制
// paginationInterceptor.setLimit(500);
// 开启 count 的 join 优化,只针对部分 left join
// paginationInterceptor.setCountSqlParser(new JsqlParserCountOptimize(true));
return paginationInterceptor;
}
//注册逻辑删除插件
@Bean
public ISqlInjector sqlInjector(){
return new LogicSqlInjector();
}
//注册性能插件
@Bean
// 设置 dev test 环境开启
@Profile({"dev","test"})
public PerformanceInterceptor performanceInterceptor() {
PerformanceInterceptor performanceInterceptor = new PerformanceInterceptor();
performanceInterceptor.setMaxTime(50);
//ms，超过此处设置的ms则sql不执行
//performanceInterceptor.setFormat(true);
return performanceInterceptor;
}
}
五、配置自动生成类（CodeGenerator.java）
1、控制台输入
public class CodeGenerator {
//0、读取控制台内容
public static String scanner(String tip) {
Scanner scanner = new Scanner(System.in);
StringBuilder help = new StringBuilder();
help.append("请输入" + tip + "：");
System.out.println(help.toString());
if (scanner.hasNext()) {
String ipt = scanner.next();
if (StringUtils.isNotBlank(ipt)) {
return ipt;
}
}
throw new MybatisPlusException("请输入正确的" + tip + "！");
}
public static void main(String[] args) {
//1、获取代码生成器对象
AutoGenerator mpg = new AutoGenerator();
//2、全局配置
GlobalConfig gc = new GlobalConfig();
//获取用户目录
String projectPath = System.getProperty("user.dir");
//代码生成路径
gc.setOutputDir(projectPath + "/src/main/java");
//作者信息
gc.setAuthor("黄果");
gc.setOpen(false);
//生成ID类型
gc.setIdType(IdType.AUTO);
gc.setDateType(DateType.ONLY_DATE);
gc.setFileOverride(true);
//去掉Servce前缀
gc.setServiceImplName("%sService");
mpg.setGlobalConfig(gc);
//3、数据源配置
DataSourceConfig dsc = new DataSourceConfig();
dsc.setUrl("jdbc:mysql://localhost:3306/school?useUnicode=true&useSSL=false&characterEncoding=utf8");
dsc.setDriverName("com.mysql.jdbc.Driver");
dsc.setUsername("root");
dsc.setPassword("123456");
dsc.setDbType(DbType.MYSQL);
mpg.setDataSource(dsc);
//4、包配置
PackageConfig pc = new PackageConfig();
//设置模块名 com.iflytek.project
//pc.setModuleName("project"); //没有第0步时此代码必写
pc.setModuleName(scanner("模块名")); //第0步省略时此代码可删
//5、设置工程名
pc.setParent("com.iflytek");
//设置包名
pc.setEntity("entity");
pc.setMapper("mapper");
pc.setService("service");
pc.setController("controller");
mpg.setPackageInfo(pc);
//6、自定义配置
InjectionConfig cfg = new InjectionConfig() {
@Override
public void initMap() {
// to do nothing
}
};
//7、如果模板引擎是 freemarker
String templatePath = "/templates/mapper.xml.ftl";
//8、自定义输出配置
List<FileOutConfig> focList = new ArrayList<>();
// 自定义配置会被优先输出
focList.add(new FileOutConfig(templatePath) {
@Override
public String outputFile(TableInfo tableInfo) {
// 自定义输出文件名 ， 如果你 Entity 设置了前后缀、此处注意 xml 的名称会跟着发生变化！！
return projectPath + "/src/main/resources/mapper/" + pc.getModuleName()
+ "/" + tableInfo.getEntityName() + "Mapper" + StringPool.DOT_XML;
}
});
cfg.setFileOutConfigList(focList);
mpg.setCfg(cfg);
//9、配置模板
TemplateConfig templateConfig = new TemplateConfig();
templateConfig.setXml(null);
mpg.setTemplate(templateConfig);
//10、策略配置
StrategyConfig strategy = new StrategyConfig();
//数据库表名优先映射,配置
strategy.setInclude("person");
//下划线转驼峰命名的策略
strategy.setNaming(NamingStrategy.underline_to_camel);
//数据库命名规则
strategy.setColumnNaming(NamingStrategy.underline_to_camel);
//自动生成lombok注解
strategy.setEntityLombokModel(true);
//自动添加控制结构
strategy.setRestControllerStyle(true);
//自动添加逻辑删除策略
strategy.setLogicDeleteFieldName("deleted");
//11、设置自动填充策略
TableFill gmtCreatereate = new TableFill("gmt_create", FieldFill.INSERT);
//设置自动更新时间策略
TableFill gmtModifiedodified = new TableFill("gmt_modified", FieldFill.UPDATE);
//获取自动填充对象
ArrayList<TableFill> tableFills = new ArrayList<>();
//添加填充策略
tableFills.add(gmtCreatereate);
tableFills.add(gmtModifiedodified);
strategy.setTableFillList(tableFills);
//12、设置乐观锁策略
strategy.setVersionFieldName("version");
//设置Restful风格
strategy.setRestControllerStyle(true);
//设置连接请求 http://localhost:8080/hello_id_2
strategy.setControllerMappingHyphenStyle(true);
//第0步省略，此行代码可删
strategy.setInclude(scanner("表名，多个英文逗号分割").split(","));
mpg.setStrategy(strategy);
mpg.execute();
}
}
2、无控制台输入
package com.mao;
import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.annotation.FieldFill;
import com.baomidou.mybatisplus.annotation.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.po.TableFill;
import com.baomidou.mybatisplus.generator.config.rules.DateType;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
import java.util.ArrayList;
public class CodeGenerator {
public static void main(String[] args) {
//1、获取代码生成器对象
AutoGenerator mpg = new AutoGenerator();
//2、全局配置
GlobalConfig gc = new GlobalConfig();
//获取用户目录
String projectPath = System.getProperty("user.dir");
//代码生成路径
gc.setOutputDir(projectPath + "/src/main/java");
//作者信息
gc.setAuthor("毛毛");
gc.setOpen(false);
//生成ID类型
gc.setIdType(IdType.AUTO);
gc.setDateType(DateType.ONLY_DATE);
gc.setFileOverride(true);
//去掉Servce前缀
gc.setServiceImplName("%sService");
mpg.setGlobalConfig(gc);
//3、数据源配置
DataSourceConfig dsc = new DataSourceConfig();
dsc.setUrl("jdbc:mysql://127.0.0.1:3306/maomao?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8&useSSL=false");
dsc.setDriverName("com.mysql.cj.jdbc.Driver");
dsc.setUsername("mao");
dsc.setPassword("123");
dsc.setDbType(DbType.MYSQL);
mpg.setDataSource(dsc);
//4、包配置
PackageConfig pc = new PackageConfig();
//设置模块名 com.mao.project
pc.setModuleName("project"); //没有第0步时此代码必写
//5、设置工程名
pc.setParent("com.mao");
//设置包名
pc.setEntity("pojo");
pc.setMapper("mapper");
pc.setService("service");
pc.setController("controller");
mpg.setPackageInfo(pc);
//6、策略配置
StrategyConfig strategy = new StrategyConfig();
//数据库表名优先映射,配置
strategy.setInclude("user","userinfo","student","tb_video_info");
//下划线转驼峰命名的策略
strategy.setNaming(NamingStrategy.underline_to_camel);
//数据库命名规则
strategy.setColumnNaming(NamingStrategy.underline_to_camel);
//自动生成lombok注解
strategy.setEntityLombokModel(true);
//自动添加控制结构
strategy.setRestControllerStyle(true);
//自动添加逻辑删除策略
strategy.setLogicDeleteFieldName("deleted");
//7、设置自动填充策略
TableFill gmtCreatereate = new TableFill("gmt_create", FieldFill.INSERT);
//设置自动更新时间策略
TableFill gmtModifiedodified = new TableFill("gmt_modified", FieldFill.UPDATE);
//获取自动填充对象
ArrayList<TableFill> tableFills = new ArrayList<>();
//添加填充策略
tableFills.add(gmtCreatereate);
tableFills.add(gmtModifiedodified);
strategy.setTableFillList(tableFills);
//8、设置乐观锁策略
strategy.setVersionFieldName("version");
//设置Restful风格
strategy.setRestControllerStyle(true);
//设置连接请求 http://localhost:8080/hello_id_2
strategy.setControllerMappingHyphenStyle(true);
mpg.setStrategy(strategy);
mpg.execute();
}
