1.首先在Androidstudio 项目的build.grad 文件中引入一下文件

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.1'
        classpath 'org.greenrobot:greendao-gradle-plugin:3.2.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

2.在module的build.gradle文件中添加greenDAO的插件，并引入相关类库

apply plugin: 'com.android.application'
apply plugin: 'org.greenrobot.greendao'
apply plugin: 'android-apt'
android {
    compileSdkVersion 24
    buildToolsVersion "24.0.2"
    defaultConfig {
        applicationId "com.mvp.observer"
        minSdkVersion 15
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    greendao{
        schemaVersion 1

    daoPackage '自己的项目名.gen'

targetGenDir 'src/main/java'

}

dependencies {

androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2',

{

exclude group: 'com.android.support', module: 'support-annotations'

})

compile 'com.android.support:appcompat-v7:24.2.1'

testCompile 'junit:junit:4.12'

compile 'org.greenrobot:greendao:3.2.0'

compile 'com.android.support:recyclerview-v7:24.2.1'}

3 .在项目包下创建实体类

@Entity
public class User {

只创建红色部分其他的编译过后自动生成 还会生成三个类分别是在gen里的DaoMaster和DaoSession和UsereDao
    @Id
    Long id;
    @Property(nameInDb = "name")
    String name;
    @Generated(hash = 873297011)
    public User(Long id, String name) {
        this.id = id;
        this.name = name;
    }
    @Generated(hash = 586692638)
    public User() {
    }
    public Long getId() {
        return this.id;
    }
    public void setId(Long id) {
        this.id = id;
    }
    public String getName() {
        return this.name;
    }
    public void setName(String name) {
        this.name = name;
    }
   
}
