android集成greendao 3.3.0

1. build.gradle(:app)配置,添加：

   apply plugin: 'org.greenrobot.greendao'

   添加引用：

   implementation 'org.greenrobot:greendao:3.3.0'

   添加greedao配置：

   greendao {
       schemaVersion 1
       daoPackage 'com.test.dao'
       targetGenDir 'src/main/java'
   }

   完整配置：

2. build.gradle(:My Application)配置，添加：

   buildscript {
       repositories {
           jcenter()
       }
       dependencies {
           classpath 'com.android.tools.build:gradle:7.1.2'
           classpath 'org.greenrobot:greendao-gradle-plugin:3.3.0'
       }
   }​

3. 在项目中的实体类中添加@Entity注解:

   @Entity
   public class TestUser {
       private Long userId;
       private String nickname;
       private String headIcon;
   }​

4. 重新构建一下项目第三步中的实体类变为：

   @Entity
   public class TestUser {
       private Long userId;
       private String nickname;
       private String headIcon;
       @Generated(hash = 1965623583)
       public TestUser(Long userId, String nickname, String headIcon) {
           this.userId = userId;
           this.nickname = nickname;
           this.headIcon = headIcon;
       }
       @Generated(hash = 925009630)
       public TestUser() {
       }
       public Long getUserId() {
           return this.userId;
       }
       public void setUserId(Long userId) {
           this.userId = userId;
       }
       public String getNickname() {
           return this.nickname;
       }
       public void setNickname(String nickname) {
           this.nickname = nickname;
       }
       public String getHeadIcon() {
           return this.headIcon;
       }
       public void setHeadIcon(String headIcon) {
           this.headIcon = headIcon;
       }
   }
   ​

   同时会在com.text.dao包下生成DaoMaster，DaoSession，TestUserDao三个类
