MyBatis Plus Code Generation

本文代码来自MyBatis Plus官网

1. 配置依赖

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation group: 'com.baomidou', name: 'mybatis-plus-boot-starter', version: '3.5.4'
    implementation group: 'com.baomidou', name: 'mybatis-plus-generator', version: '3.5.6'
// change before version 2.3.9 
// maybe have a error in init,so update the version 
    implementation group: 'freemarker', name: 'freemarker', version: '2.3.31'


    compileOnly 'org.projectlombok:lombok'
    runtimeOnly 'com.oracle.database.jdbc:ojdbc8'
    annotationProcessor 'org.projectlombok:lombok'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

2. 编写生成器类

演示例子，执行 main 方法控制台输入 模块名 表名 回车自动生成对应项目目录中

public class NewCodeGenerator {

    static final String URL = "jdbc:oracle:thin:@192.168.3.161:1521:jc";
    static final String USERNAME = "jc";
    static final String PASSWORD = "123456";

    public static void main(String[] args) {
        generate();
    }


    private static void generate() {
        FastAutoGenerator.create(URL, USERNAME, PASSWORD)
                .globalConfig(builder ->
                        builder.author("xx")
                                .commentDate("yyyy-MM-dd")
                                .disableOpenDir()
                                .outputDir(System.getProperty("user.dir")+"\\src\\main\\java")
                                .dateType(DateType.TIME_PACK)
                                .disableServiceInterface()
                )
                .packageConfig(builder ->
                        builder.parent("com.whalefall541.mybatisplus.samples.generator")
                                .moduleName("system")
                                .entity("po")
                                .serviceImpl("service.impl")
                                .pathInfo(Collections.singletonMap(OutputFile.xml, System.getProperty("user.dir")+"\\src\\main\\resources\\mapper\\test")))
            
                .strategyConfig(builder ->
                        builder.addInclude("table_a")
                                .controllerBuilder()
                                .enableFileOverride()
                                .enableRestStyle()
                                .disable()

                                .entityBuilder()
                                .enableFileOverride()
                                .enableLombok()
                                .disableSerialVersionUID()
                                .enableTableFieldAnnotation()
                                .enableActiveRecord()
                                .enableFileOverride()
//                                .addTableFills(new Column("timecolunmn", FieldFill.INSERT))
                                .formatFileName("%sPO")

                                .serviceBuilder()
                                .disable()
                                .enableFileOverride()
                                .formatServiceImplFileName("%sServiceImpl")

                                .mapperBuilder()
                                .enableFileOverride()
                                .mapperAnnotation(Mapper.class)

                ).templateEngine(new FreemarkerTemplateEngine()).execute();
    }

}
