android中使用greedDao
一 工具说明
Greendao是一个在android中快速生成数据库操作的orm工具,最近在项目中使用到,具体操作记录如下,供以后使用快速集成。
该项目的源码在gitee的镜像地址为:【https://gitee.com/freewsf/greenDAO_1#add-greendao-to-your-project】
二 使用方式
1.在project的buildgrade中添加依赖仓库地址
buildscript { repositories { jcenter() google() mavenCentral() //greendao plugin托管在中央仓库,要添加这一个 } dependencies { classpath 'com.android.tools.build:gradle:3.5.3' classpath 'org.greenrobot:greendao-gradle-plugin:3.3.0' // 添加插件 // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } }
2. 在app的buildgradle中添加插件的应用规则及依赖
apply plugin: 'com.android.application' apply plugin: 'org.greenrobot.greendao' //应用插件 android { compileSdkVersion 30 buildToolsVersion "30.0.3" defaultConfig { applicationId "com.xxx.xxx" minSdkVersion 19 targetSdkVersion 30 versionCode 20210820 versionName "2.0" testInstrumentationRunner 'androidx.test.runner.AndroidJUnitRunner' ndk { // 设置支持的SO库架构,'armeabi' , 'x86', 'armeabi-v7a', 'x86_64', 'arm64-v8a' abiFilters 'armeabi','armeabi-v7a', 'arm64-v8a', 'x86' } sourceSets { main { jniLibs.srcDirs = ['libs'] } } } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } //so 库目录加入 sourceSets.main.jniLibs.srcDirs = ['libs'] //定义greendao 自动生成dao代码的路径和规则 greendao { //指定数据库schema版本号,迁移等操作会用到; schemaVersion 1 //dao的包名,包名默认是entity所在的包; daoPackage 'com.xxx.yyy.dbutil.dao' //生成数据库文件的目录; targetGenDir 'src/main/java' }
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar', '*.aar'], exclude: [])
androidTestCompile('androidx.test.espresso:espresso-core:3.1.0', {
exclude group: 'com.android.support', module: 'support-annotations'
})
implementation 'androidx.appcompat:appcompat:1.0.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'com.google.zxing:core:3.3.0'
testImplementation 'junit:junit:4.12'
//腾讯的键值对存储mmkv
implementation 'com.tencent:mmkv:1.0.22'
//添加lombok包支持
compile 'org.projectlombok:lombok:1.18.10'
annotationProcessor 'org.projectlombok:lombok:1.18.10'
//greenDao
implementation 'org.greenrobot:greendao:3.3.0'
//gson
implementation 'com.google.code.gson:gson:2.8.5'
}
3. 添加一个实体类,比如
import org.greenrobot.greendao.annotation.Entity; import org.greenrobot.greendao.annotation.Id; import java.io.Serializable; import java.util.Date; import lombok.Builder; import lombok.Data; import org.greenrobot.greendao.annotation.Generated; @Entity @Data @Builder public class MachineOrder implements Serializable { private static final long serialVersionUID = 1L; @Id(autoincrement = true) private Long id; private String machineOrderNo; private String uploadAlready; private String rawQrCodeInfo; private Date createTime; private Date uploadTime; }
4. 准备完毕,点击 Build->make project.
这时候可以看到,在我们配置的 daoPackage 'com.xxx.yyy.dbutil.dao' 这个目录下面,已经自动生成了
