java Roboguice抛出ClassNotFoundException:AnnotationDatabaseImpl
我有一个多模块项目,它有一个从RoboActivity派生的类,带有一些注入的pojo字段
这些字段的类也注入了字段,而这些字段反过来也注入了字段。其中一些类生活在不同的模块中,所以我需要的是跨模块注入
我按照Robo Blenders wiki(据说)中的说明操作,但在尝试运行应用程序时,我得到了“ClassNotFoundException:AnnotationDatabaseImpl”,应用程序停止了
以下是类(未显示接口):
@ContentView(R.layout.activity_about)
public class AboutActivityImpl extends AbstractActivityImpl implements AbstractActivity, AboutActivity {
@InjectView(R.id.app_name) private TextView app_name;
@InjectView(R.id.app_copyright) private TextView app_copyright;
@InjectView(R.id.app_version) private TextView app_version;
// MVP
@Inject
AboutPresenter presenter; //IS INJECTED
// MVP
@Override
protected MvpEvent setPresenter() {
setPresenter(presenter);
return new AboutActivityInitEvent();
}
.
.
.
}
public class AboutPresenterImpl extends AbstractPresenterImpl implements AboutPresenter {
@Inject
AppInfo appInfo; //IS INJECTED
@SuppressWarnings("unused")
@Inject @Config(Property.APP_COPYRIGHT) //IS INJECTED
private String appCopyright;
.
.
.
}
public class AppInfoImpl implements AppInfo {
@Inject
AppInfoApi appInfoApi; //IS NOT INJECTED!!
public AppInfoImpl() {
}
.
.
.
}
public class AppInfoApiImpl implements AppInfoApi {
@Inject
Application application; //IS NOT INJECTED!!
public AppInfoApiImpl() {
}
.
.
.
}
Roboguice模块如下所示:
public class AppModule extends AbstractModule {
@Override
protected void configure() {
bind(AboutPresenter.class).to(AboutPresenterImpl.class);
}
}
public class DomainModule extends AbstractModule {
@Override
protected void configure() {
bind(AppInfo.class).to(AppInfoImpl.class);
}
}
public class PlatformModule extends AbstractModule {
@Override
protected void configure() {
bind(AppInfoApi.class).to(AppInfoApiImpl.class);
}
}
清单如下:
<manifest xmlns:安卓="http://schemas.安卓.com/apk/res/安卓"
package="ar.com.abimobileapps.安卓app">
<application
安卓:allowBackup="true"
安卓:icon="@mipmap/ic_launcher"

安卓:supportsRtl="true"
安卓:theme="@style/AppTheme">

这些是构建的模块。gradle文件(片段):
建造。gradle(应用程序模块):
dependencies {
.
.
.
// Roboguice
compile 'org.roboguice:roboguice:3.0.1'
provided 'org.roboguice:roboblender:3.0.1'
// Modules
compile project(':domain')
compile project(':platform')
compile project(':configuration')
}
project.tasks.withType(JavaCompile) { task ->
options.compilerArgs << "-AguiceAnnotationDatabasePackageName=ar.com.abimobileapps.安卓app"
}
建造。gradle(域模块):
dependencies {
.
.
.
// Roboguice
compile 'org.roboguice:roboguice:3.0.1'
provided 'org.roboguice:roboblender:3.0.1'
// Modules
compile project(':persistence')
compile project(':platform')
}
project.tasks.withType(JavaCompile) { task ->
options.compilerArgs << "-AguiceAnnotationDatabasePackageName=ar.com.abimobileapps.安卓app.domain"
}
建造。gradle(持久性模块):
dependencies {
.
.
.
// Roboguice
compile 'org.roboguice:roboguice:3.0.1'
provided 'org.roboguice:roboblender:3.0.1'
}
project.tasks.withType(JavaCompile) { task ->
options.compilerArgs << "-AguiceAnnotationDatabasePackageName=ar.com.abimobileapps.安卓app.persistence"
}
建造。gradle(平台模块):
dependencies {
.
.
.
// Roboguice
compile 'org.roboguice:roboguice:3.0.1'
provided 'org.roboguice:roboblender:3.0.1'
}
project.tasks.withType(JavaCompile) { task ->
options.compilerArgs << "-AguiceAnnotationDatabasePackageName=ar.com.abimobileapps.platform"
}
注释数据库impl。类文件是为包ar.com生成的。abimobileapps。安卓app,ar.com。abimobileapps。安德洛伊达普。域名,ar.com。abimobileapps。安德洛伊达普。持久性和ar.com。abimobileapps。站台检查其源代码时,我看到所有注入类和“to inject”类都被引用
因此,我无法理解为什么在运行应用程序时会出现“ClassNotFoundException:AnnotationDatabaseImpl”
正确注入的类(AboutActivityImpl、AboutPresentImpl和AppModule)位于同一个项目模块中,而其他两个类(失败的类)位于两个不同的项目模块中(一个模块中的AppInfo/DomainModule,另一个模块中的AppInfoApi/PlatformModule)
Roboguice是3.0.1版
知道吗
# 1 楼答案
您可以设置
Roboguice.setUseAnnotationDatabases(false)
以防止出现异常。另外,我建议您转到Roboguice 4.0。你可以在Github上的Roboguice项目中找到Roboguice 4.0作为分支rg-4-final
。Rg 4.0更轻,因此性能更好
