代码：

public class CodeGenerator  {

    public static void main(String[] args) {
        // 需要构建一个代码自动生成器对象
        AutoGenerator mpg = new AutoGenerator();

        // 配置策略
        // 1、全局配置
        GlobalConfig gc = new GlobalConfig();
        String projectPath = System.getProperty("user.dir");
        gc.setOutputDir(projectPath + "/src/main/java");
        gc.setAuthor("你的名字");
        gc.setOpen(false);
        gc.setFileOverride(false);
        // 去掉Service的I前缀
        gc.setServiceName("%sService");
        gc.setIdType(IdType.ID_WORKER);
        gc.setDateType(DateType.ONLY_DATE);
        gc.setSwagger2(true);
        mpg.setGlobalConfig(gc);

        // 2、设置数据源
        DataSourceConfig dsc = new DataSourceConfig();
        dsc.setUrl("jdbc:mysql://localhost:3306/mybatis_plus?useSSL=false&useUnicode=true&characterEncoding=utf-8&serverTimezone=GMT%2B8");
        dsc.setDriverName("com.mysql.cj.jdbc.Driver");
        dsc.setUsername("root");
        dsc.setPassword("root");
        dsc.setDbType(DbType.MYSQL);
        mpg.setDataSource(dsc);

        // 3、包的配置
        PackageConfig pc = new PackageConfig();
        pc.setModuleName("blog");
        pc.setParent("cn.com.dwr");
        pc.setEntity("pojo");
        pc.setMapper("mapper");
        pc.setService("service");
        pc.setController("controller");
        mpg.setPackageInfo(pc);

        // 4、策略配置
        StrategyConfig strategy = new StrategyConfig();
        // 设置要映射的表名
        strategy.setInclude("student");
        strategy.setNaming(NamingStrategy.underline_to_camel);
        strategy.setColumnNaming(NamingStrategy.underline_to_camel);
        // 自动lombok
        strategy.setEntityLombokModel(true);
        strategy.setLogicDeleteFieldName("deleted");
        // 自动填充配置
        TableFill createTime = new TableFill("create_time", FieldFill.INSERT);
        TableFill updateTime = new TableFill("update_time", FieldFill.INSERT_UPDATE);
        List<TableFill> tableFillList = new ArrayList<>();
        tableFillList.add(createTime);
        tableFillList.add(updateTime);
        // 乐观锁
        strategy.setVersionFieldName("version");
        strategy.setRestControllerStyle(true);
        strategy.setControllerMappingHyphenStyle(true);
        mpg.setStrategy(strategy);

        // 执行
        mpg.execute();
    }
}

生成效果：

数据库：

Student类：

@Data
@EqualsAndHashCode(callSuper = false)
@Accessors(chain = true)
@ApiModel(value="Student对象", description="")
public class Student implements Serializable {

    private static final long serialVersionUID = 1L;

    @ApiModelProperty(value = "id")
    @TableId(value = "id", type = IdType.ID_WORKER)
    private Integer id;

    @ApiModelProperty(value = "姓名")
    private String name;

    @ApiModelProperty(value = "年龄")
    private Integer age;

    @ApiModelProperty(value = "性别")
    private Integer sex;

    @ApiModelProperty(value = "邮箱")
    private String email;

    @ApiModelProperty(value = "版本")
    @Version
    private Integer version;

    @ApiModelProperty(value = "逻辑删除")
    @TableLogic
    private Integer deleted;

    @ApiModelProperty(value = "创建时间")
    @TableField("createTime")
    private Date createTime;

    @ApiModelProperty(value = "更新时间")
    @TableField("updateTime")
    private Date updateTime;

}

StudentMapper类：

public interface StudentMapper extends BaseMapper<Student> {

}

StudentMapper.xml：

DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="cn.com.dwr.blog.mapper.StudentMapper">

mapper>

StudentService类：

public interface StudentService extends IService<Student> {

}

StudentServiceImpl类：

@Service
public class StudentServiceImpl extends ServiceImpl<StudentMapper, Student> implements StudentService {

}

Controller类：

@RestController
@RequestMapping("/blog/student")
public class StudentController {

}

需要时直接复制代码，修改数据源和要生成的表名即可。
