mybatisPlus 逆向工程-通过表格创建实体类

1、引入依赖

　　

<!-- SpringBoot集成mybatis-plus框架 -->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
        </dependency>

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>

        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-generator</artifactId>
        </dependency>
        <dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity-engine-core</artifactId>
        </dependency>

 

2、配置数据库，项目路径等

　　

public class MybatisPlusCodeGenerator {

    public static void main(String[] args) {
        //
        final String projectPath = System.getProperty("user.dir");
        final String moduleName = scanner("模块名");
        final String tableName = scanner("表名，多个英文逗号分割");
        AutoGenerator mpg = new AutoGenerator()
                .setGlobalConfig(
                        // 全局配置
                        new GlobalConfig()
                                .setOutputDir(projectPath + "/cloud-provider-8001/src/main/java") //项目路径
                                .setFileOverride(true)
                                .setAuthor("junHong") 
                                .setOpen(false)
                                .setBaseResultMap(true)
                                .setBaseColumnList(true)
                ).setDataSource(
                        // 数据源配置
                        new DataSourceConfig()
                                .setUrl("jdbc:mysql://192.168.1.1:3306/db1?useUnicode=true&useSSL=false&characterEncoding=utf8")
                                .setDriverName("com.mysql.cj.jdbc.Driver")
                                .setUsername("自己的数据库用户名")
                                .setPassword("摸吗"))
                .setPackageInfo(
                        // 包配置
                        new PackageConfig()
                                .setParent("com.casaba.provider")
                                .setEntity("domain." + moduleName)
                                .setMapper("mapper." + moduleName)
                                .setService("service." + moduleName)
                                .setServiceImpl("service." + moduleName + ".impl")
                ).setStrategy(
                        // 策略配置
                        new StrategyConfig()
                                .setNaming(underline_to_camel)
                                .setColumnNaming(underline_to_camel)
                                .setSuperEntityClass("com.casaba.provider.domain.BaseDomain")
                                .setSuperEntityColumns(new String[]{"create_at", "update_at"})
                                .setEntityLombokModel(true)
                                .setEntityBooleanColumnRemoveIsPrefix(true)
                                .setEntityTableFieldAnnotationEnable(true)
                                .setInclude(StringUtils.split(tableName, ","))
                                .setTablePrefix("t")
                ).setCfg(
                        // 注入自定义配置，可以在 VM 中使用 cfg.abc 设置的值
                        new InjectionConfig() {
                            @Override
                            public void initMap() {
                            }
                        }.setFileOutConfigList(Collections.singletonList(new FileOutConfig("/templates/mapper.xml.vm") {
                            // 自定义输出文件目录
                            @Override
                            public String outputFile(TableInfo tableInfo) {
                                return projectPath + "/cloud-provider-8001/src/main/resources/mapper/" + moduleName + "/" + tableInfo.getEntityName() + "Mapper" + StringPool.DOT_XML;
                            }
                        }))
                ).setTemplate(new TemplateConfig()
                        .setController(null)
                        .setXml(null));

        mpg.execute();
    }
