Android greenDAO使用demo

Android greenDAO使用的demo，实现数据库的增删改查

package com.example;

import de.greenrobot.daogenerator.DaoGenerator;
import de.greenrobot.daogenerator.Entity;
import de.greenrobot.daogenerator.Schema;

public class Generator {
    public static void main（String[] args） throws Exception {

        int version=1;
        String defaultPackage=“test.greenDAO.bean“;
        //创建模式对象，指定版本号和自动生成的bean对象的包名
        Schema schema=new Schema（versiondefaultPackage）;
        //指定自动生成的dao对象的包名不指定则都DAO类生成在“test.greenDAO.bean“包中
        schema.setDefaultJavaPackageDao（“test.greenDAO.dao“）;

        //添加实体
        addEntity（schema）;

        String outDir=“D:/adt-bundle-windows-x64/workspace/studio/frame/study_demo/testgreendao/src/main/java-gen“;
        //调用DaoGenerator（）.generateAll方法自动生成代码到之前创建的java-gen目录下
        new DaoGenerator（）.generateAll（schemaoutDir）;

    }

    private static void addEntity（Schema schema） {
        //添加一个实体，则会自动生成实体Entity类
        Entity entity = schema.addEntity（“Entity“）;
        //指定表名，如不指定，表名则为 Entity（即实体类名）
        entity.setTableName（“student“）;
        //给实体类中添加属性（即给test表中添加字段）
        entity.addIdProperty（）.autoincrement（）;//添加Id自增长
        entity.addStringProperty（“name“）.notNull（）;//添加String类型的name不能为空
        entity.addIntProperty（“age“）;//添加Int类型的age
        entity.addDoubleProperty（“score“）;//添加Double的score
    }
}
