Annotation Type Around


  • @Documented
    @Retention(RUNTIME)
    @Target({ANNOTATION_TYPE,TYPE,METHOD})
    @InterceptorBinding(kind=AROUND)
    public @interface Around

    Annotation stereotype to applied to other annotations to indicate the annotation provides Around advice.

    Around advice decorates a method invocation such that the method can be intercepted via a MethodInterceptor

    For example:

    
      @Around
      @Type(ExampleInterceptor.class)
      @Documented
      @Retention(RUNTIME)
       public @interface Example {
       }
     

    Note that the annotation MUST be RetentionPolicy.RUNTIME and the specified Type must implement MethodInterceptor

      • proxyTarget

        boolean proxyTarget

        By default Micronaut will compile subclasses of the target class and call super.foo(..) to invoke the original method since this is more efficient and allows proxied methods to work for calls from within the class.

        However certain cases it may be useful to be able to to instead proxy all public methods of the original implementation. By setting the value here to true the Interceptor can specify that it requires proxying of the class

        Generated subclasses will implement InterceptedProxy if this attribute is set to true

        Returns:
        True if the original implementation should be proxied. Defaults to false.
        See Also:
        InterceptedProxy
        Default:
        false
      • lazy

        boolean lazy

        By default Micronaut will initialize the proxy target eagerly when the proxy is created. This is better for performance, but some use cases may require the bean to be resolved lazily (for example for resolving the bean from a custom scope).

        If proxyTarget() is set to true then one can optionally set the of lazy to true

        Returns:
        True if the proxy target should be resolved lazily
        Default:
        false
      • cacheableLazyTarget

        boolean cacheableLazyTarget
        If true the proxy cache and reuse the target.
        Returns:
        True if the proxy target should be cacheable
        Since:
        3.1.0
        Default:
        false
