1.配置项目下的build

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath ("org.jetbrains.kotlin:kotlin-gradle-plugin:1.9.0")
        classpath ("org.greenrobot:greendao-gradle-plugin:3.3.1") // 使用最新版本
    }
}

2.配置app下的build

id("org.jetbrains.kotlin.kapt")
id("org.greenrobot.greendao")

kapt {
    arguments {
        arg("daoPackage", "你的ApplicatinId")
        arg("databaseName", "你的数据库名称-db")
        arg("targetGenDir", "/src/main/java")
        arg("schemaVersion", "1")
    }
}

implementation("org.greenrobot:greendao:3.2.2")
kapt("org.greenrobot:greendao-generator:3.2.2")

3.初始化数据库

class App : Application() {

    private var myOpenHelper: MyOpenHelper? = null
    private var db: SQLiteDatabase? = null
    private var mDaoMaster: DaoMaster? = null
    private var mDaoSession: DaoSession? = null

    override fun onCreate() {
        super.onCreate()
        setDatabase()
    }

    private fun setDatabase() {
        myOpenHelper = MyOpenHelper(this, "你的数据库名称-db", null)
        db = myOpenHelper!!.writableDatabase
        mDaoMaster = DaoMaster(db)
        mDaoSession = mDaoMaster!!.newSession()
    }

    fun getmDaoSession(): DaoSession? {
        mDaoSession = mDaoMaster!!.newSession()
        return mDaoSession
    }

    inner class MyOpenHelper(context: Context?, name: String?, factory: CursorFactory?) :
        DaoMaster.OpenHelper(context, name, factory)

}

4.实体类

@Entity
public class TypeEntity {

    @Id(autoincrement = true)
    private Long id;
    private int color;
    private String type;
}

5.实例类写好之后锤子🔨锤一下就自动生成后续代码了 【快捷键忘了，如果有记得的同学，欢迎留言Thanks♪(･ω･)ﾉ 】。
