使用mybatis-plus代码生成器

一.导入依赖

<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <parent> <artifactId>managementplatform</artifactId> <groupId>com.lqs</groupId> <version>0.0.1-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion>
 <artifactId>codeGenerator</artifactId> <dependencies>
 <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>3.1.1</version> </dependency> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-generator</artifactId> <version>3.1.1</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-freemarker</artifactId> </dependency> <!--mysql驱动--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency><!-- <dependency>--><!-- <groupId>org.slf4j</groupId>--><!-- <artifactId>slf4j-log4j12</artifactId>--><!-- </dependency>--> </dependencies>
 <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build>
</project>

二.编写生成类

package com.lqs.blog;

import com.baomidou.mybatisplus.core.exceptions.MybatisPlusException;import com.baomidou.mybatisplus.core.toolkit.StringPool;import com.baomidou.mybatisplus.core.toolkit.StringUtils;import com.baomidou.mybatisplus.generator.AutoGenerator;import com.baomidou.mybatisplus.generator.InjectionConfig;import com.baomidou.mybatisplus.generator.config.*;import com.baomidou.mybatisplus.generator.config.po.TableInfo;import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;
import java.util.ArrayList;import java.util.List;import java.util.Scanner;
// 演示例子，执行 main 方法控制台输入模块表名回车自动生成对应项目目录中public class CodeGenerator {
 /** * <p> * 读取控制台内容 * </p> */ 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.isNotEmpty(ipt)) { return ipt; } } throw new MybatisPlusException("请输入正确的" + tip + "！"); }
 /** * RUN THIS */ public static void main(String[] args) { // 代码生成器 AutoGenerator mpg = new AutoGenerator(); // 全局配置 GlobalConfig gc = new GlobalConfig(); String projectPath = System.getProperty("user.dir"); System.out.println("projectPath:" + projectPath);//projectPath:E:\springboot\ManagementPlatform gc.setOutputDir(projectPath + "/codeGenerator/src/main/java"); gc.setAuthor("codedog"); gc.setOpen(false); mpg.setGlobalConfig(gc);
 // 数据源配置 DataSourceConfig dsc = new DataSourceConfig(); dsc.setUrl("jdbc:mysql://localhost:3306/blog?useUnicode=true&useSSL=false&characterEncoding=utf8&serverTimezone=UTC"); // dsc.setSchemaName("public"); dsc.setDriverName("com.mysql.cj.jdbc.Driver"); dsc.setUsername("root"); dsc.setPassword("123456"); mpg.setDataSource(dsc);
 // 包配置 PackageConfig pc = new PackageConfig(); pc.setModuleName((scanner("模块名"))); pc.setParent("com.lqs.blog"); mpg.setPackageInfo(pc);
 // 自定义配置 InjectionConfig cfg = new InjectionConfig() { @Override public void initMap() { // to do nothing } };
 // 如果模板引擎是 freemarker String templatePath = "/templates/mapper.xml.ftl"; // 如果模板引擎是 velocity // String templatePath = "/templates/mapper.xml.vm";
 // 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 + "/codeGenerator/src/main/resources/mapper/" + pc.getModuleName() + "/" + tableInfo.getEntityName() + "Mapper" + StringPool.DOT_XML; } });
 cfg.setFileOutConfigList(focList); mpg.setCfg(cfg);
 // 配置模板 TemplateConfig templateConfig = new TemplateConfig(); templateConfig.setXml(null); mpg.setTemplate(templateConfig);
 // 策略配置 StrategyConfig strategy = new StrategyConfig(); strategy.setNaming(NamingStrategy.underline_to_camel); strategy.setColumnNaming(NamingStrategy.underline_to_camel); strategy.setEntityLombokModel(true);// strategy.setRestControllerStyle(true); strategy.setInclude(scanner("表名，多个英文逗号分割").split(",")); strategy.setControllerMappingHyphenStyle(true); strategy.setTablePrefix(pc.getModuleName() + "_"); mpg.setStrategy(strategy); // 选择 freemarker 引擎需要指定如下加，注意 pom 依赖必须有！ mpg.setTemplateEngine(new FreemarkerTemplateEngine()); mpg.execute(); }}
