Guice 简明教程
Google Guice - Inbuilt Bindings
Guice 为 java.util.logging.Logger 类提供内置绑定。Logger 的名称会自动设置为 Logger 被注入到的类的名称。请参见以下示例。
Guice provides inbuilt binding for java.util.logging.Logger class. Logger’s name is automatically set to the name of the class into which the Logger is injected. See the example below.
Example
创建名为 GuiceTester 的 Java 类。
Create a java class named GuiceTester.
GuiceTester.java
import java.util.logging.Logger;
import com.google.inject.AbstractModule;
import com.google.inject.Guice;
import com.google.inject.Inject;
import com.google.inject.Injector;
public class GuiceTester {
public static void main(String[] args) {
Injector injector = Guice.createInjector(new TextEditorModule());
TextEditor editor = injector.getInstance(TextEditor.class);
editor.makeSpellCheck();
}
}
class TextEditor {
private Logger logger;
@Inject
public TextEditor( Logger logger) {
this.logger = logger;
}
public void makeSpellCheck(){
logger.info("In TextEditor.makeSpellCheck() method");
}
}
//Binding Module
class TextEditorModule extends AbstractModule {
@Override
protected void configure() {
}
}
