Spring AOP works without @EnableAspectJAutoProxy?
The @SpringBootApplication
annotation contains the @EnableAutoConfiguration
annotation. This autoconfiguration is one of the attractions of Spring Boot and makes configuration simpler. The auto configuration uses @Conditional
type annotations (like @ConditionalOnClass
and @ConditionalOnProperty
) to scan the classpath and look for key classes that trigger the loading of 'modules' like AOP.
Here is an example AopAutoConfiguration.java
import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.reflect.Advice;import org.aspectj.weaver.AnnotatedElement;@Configuration@ConditionalOnClass({ EnableAspectJAutoProxy.class, Aspect.class, Advice.class, AnnotatedElement.class })@ConditionalOnProperty(prefix = "spring.aop", name = "auto", havingValue = "true", matchIfMissing = true)public class AopAutoConfiguration { @Configuration @EnableAspectJAutoProxy(proxyTargetClass = false) @ConditionalOnProperty(prefix = "spring.aop", name = "proxy-target-class", havingValue = "false", matchIfMissing = false) public static class JdkDynamicAutoProxyConfiguration { } @Configuration @EnableAspectJAutoProxy(proxyTargetClass = true) @ConditionalOnProperty(prefix = "spring.aop", name = "proxy-target-class", havingValue = "true", matchIfMissing = true) public static class CglibAutoProxyConfiguration { }}
As you can see, if you add one of the above aop classes to your class path (or property), Spring will detect it and effectively behave as if you had the @EnableAspectJAutoProxy annotation on your main class.
Your project has a file LoggerHogger which has an @Aspect.
