在接口中修改@Inject getter (从AEM传入)是指在Adobe Experience Manager (AEM)中通过@Inject注解来获取并修改接口中的getter方法。
具体步骤如下:
public interface MyInterface {
String getExampleProperty();
void setExampleProperty(String exampleProperty);
}
@Component(service = Servlet.class)
public class MyServlet extends SlingSafeMethodsServlet {
@Inject
private MyInterface myInterface;
@Override
protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException {
// 通过myInterface对象获取属性值
String exampleProperty = myInterface.getExampleProperty();
// 修改属性值
myInterface.setExampleProperty("new value");
// 其他处理逻辑...
}
}
@Component(
service = {MyInterface.class},
configurationPolicy = ConfigurationPolicy.REQUIRE
)
@Designate(ocd = MyInterfaceImpl.Config.class)
public class MyInterfaceImpl implements MyInterface {
private String exampleProperty;
@Override
public String getExampleProperty() {
return exampleProperty;
}
@Override
public void setExampleProperty(String exampleProperty) {
this.exampleProperty = exampleProperty;
}
@ObjectClassDefinition(name = "My Interface Configuration")
public @interface Config {
@AttributeDefinition(name = "Example Property", description = "Example property description")
String exampleProperty() default "default value";
}
}
在配置页面中,可以修改属性"exampleProperty"的值。
总结: 通过在接口中使用@Inject注解,可以从AEM中获取并修改属性值。这种方式可以灵活地配置和管理接口的属性,使得在使用接口的类中可以直接访问并修改属性的值。在AEM中,推荐使用Sling框架提供的@Inject注解来实现属性的注入和修改。
