spring-aop

I know about @Valid annotation to instruct spring to validate for example a Controller argument according to JSR-303 in such this example: @GetMapping("/test") public TestDTO testDTO(@Valid TestDTO testDTO){ return testDTO; } But I would like to be able to configure Spring in some way to enable validation in all my controllers without specify explicitly the @Valid annotation. Is that possible in any way? Some Spring configuration? Making use of AOP?... I have finally came across with a working solution which may be not the optimal from the point of view of Spring configuration (as I said I'm

I am using Spring 3 AOP, and I have an aspect that requires access to the HttpServletRequest. It looks something like this: @Aspect public class MyAspect { @Autowired private HttpServletRequest httpServletRequest; public void init() { // Do something once... } @Before("my pointcut here...") private void myMethod() { // I need the httpServletRequest... } @After("my pointcut here...") private void myOtherMethod() { // I need the httpServletRequest... } } And is configured like this: <bean id="myAspect" class="com.some.package.MyAspect" init-method="init" /> Is the init method only called once

I'm having trouble with a pointcut definition in Spring (version 2.5.6). I'm trying to intercept all method calls to a class, except for a given method (someMethod in the example below). <aop:config> <aop:advisor pointcut="execution(* x.y.z.ClassName.*(..)) AND NOT execution(* x.y.x.ClassName.someMethod(..))" /> </aop:config> However, the interceptor is invoked for someMethod as well. Then I tried this: <aop:config> <aop:advisor pointcut="execution(* x.y.z.ClassName.(* AND NOT someMethod)(..)) )" /> </aop:config> But this does not compile as it is not valid syntax (I get a

I'm looking for a feature or software, who will allow me to easily profile my method execution time and choose what to profile by package filter. I know, it's profiler 101. I use the TPTP profiler. But I'm not happy with it. To be frank I just don't understand how it works, and when I profile my application (launch the server in profiling mode), it takes forever to do nothing. (well, not what I expect: a simple output of execution time) So I do the profiling myself with system time (add a line at beginning and at ending of methods). It's not so bad. My question is : I want to measure system

I have a service interface with many methods, all of which take a Request object and return a Response object. All request objects have a common ancestor and all response objects have a different common ancestor (which has a success flag and a message field). Now I want to have an around aspect that checks permissions etc, performs the service call and returns a Response object with a failure code if anything fails. The problem is: I need to know what type of Response object to create. Is there a pointcut expression that gives me access to the return type? Something like this, perhaps? @Around

I am not able to @Autowire the Service Layer Instance in Aspect. In Aspect the reference to the @Autowired bean is NULL and it throws NullPointerException . Any help will be much appreciated. I think, I messed up with configuration. Following is my servlet-context.xml : <!-- Activates various annotations to be detected in bean classes --> <context:annotation-config /> <context:spring-configured /> <!-- Scans the classpath of this application for @Components to deploy as beans --> <context:component-scan base-package="xx.yy" /> <!-- an @AspectJ aspect will be interpreted as an aspect by Spring
