Question

在Felix注释中，Servlet代码如下： sling.servlet.resourceTypes的定义为unbounded = PropertyUnbounded.ARRAY

@Component(metatype = true, label = "Test Servlet", description = "Test Servlet", configurationFactory = true, policy = ConfigurationPolicy.REQUIRE)
@Service
@Properties({
    @Property(name = "sling.servlet.resourceTypes", unbounded = PropertyUnbounded.ARRAY, label = "Sling Resource Type", description = "Sling Resource Type for the Home Page component or components."),
    @Property(name = "sling.servlet.selectors", value = "test-selector", propertyPrivate = true),
    @Property(name = "sling.servlet.extensions", value = "html", propertyPrivate = true),
    @Property(name = "sling.servlet.methods", value = "GET", propertyPrivate = true) })

但是当我按照以下方式将其更改为OSGI注释时，我找不到在@Component注释内初始化此sling.servlet.resourceTypes的方法

@Designate(ocd = TestServlet.Config.class)
@Component(name = "com.myproject.TestServlet", service = Servlet.class, property = {
    "service.description=Test Servlet", "sling.servlet.methods=GET",
    "sling.servlet.resourceTypes=" + ??, "sling.servlet.extensions=" + "html",
    "sling.servlet.selectors=" + "test-selector" }
)        
public final class TestServlet extends SlingSafeMethodsServlet {
 private String[] allowedResourceTypes;

 @Activate
protected void activate(Config config) {
       this.config = config;
       allowedResourceTypes = config.getResourceTypes();
       }

@ObjectClassDefinition(name="Test servlet config")
   public @interface Config {

     @AttributeDefinition(
                name = "Resource Types",
                description = "The set of resource types.",
                type = AttributeType.STRING
        )
        String[] getResourceTypes() ;
  }
}

更新：除了通过代码注册外，我找不到简单的解决方案。一个示例可能是core Adaptive component

如果您想拥有多种资源类型（基本上是一种资源类型的数组），则必须分别命名每一个：

@Designate(ocd = TestServlet.Config.class)
@Component(
  name = "com.myproject.TestServlet", 
  service = Servlet.class, property = {
    "service.description=Test Servlet", 
    "sling.servlet.methods=GET",
    "sling.servlet.resourceTypes=nt:file", 
    "sling.servlet.resourceTypes=project/components/mycomp", 
    "sling.servlet.extensions=html",
    "sling.servlet.selectors=" + "test-selector" 
  }
)        
public final class TestServlet extends SlingSafeMethodsServlet {
 private String[] allowedResourceTypes;

 @Activate
protected void activate(Config config) {
       this.config = config;
       allowedResourceTypes = config.getResourceTypes();
       }

@ObjectClassDefinition(name="Test servlet config")
   public @interface Config {

     @AttributeDefinition(
                name = "Resource Types",
                description = "The set of resource types.",
                type = AttributeType.STRING
        )
        String[] getResourceTypes() ;
  }
}

所以诀窍是要有多个 sling.servlet.resourceTypes 条目。

希望有帮助。
