本篇文章为你整理了Springboot整合AOP和注解，实现丰富的切面功能（）的详细内容，包含有 Springboot整合AOP和注解，实现丰富的切面功能，希望能帮助你了解 Springboot整合AOP和注解，实现丰富的切面功能。
我们在文章《Spring AOP与AspectJ的对比及应用》介绍了AOP的使用，这篇文章讲解一下AOP与注解的整合，通过注解来使用AOP，会非常方便。为了简便，我们还是来实现一个计时的功能。
首先创建一个注解：
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface PkslowLogTime {
然后在一个Service中使用注解：
@Service
@Slf4j
public class TestService {
@PkslowLogTime
public void fetchData() {
log.info("fetchData");
try {
Thread.sleep(500);
} catch (InterruptedException e) {
throw new RuntimeException(e);
这个Service的方法会在Controller中调用：
@GetMapping("/hello")
public String hello() {
log.info("------hello() start---");
test();
staticTest();
testService.fetchData();
log.info("------hello() end---");
return "Hello, pkslow.";
接着是关键一步，我们要实现切面，来找到注解并实现对应功能：
@Aspect
@Component
@Slf4j
public class PkslowLogTimeAspect {
@Around("@annotation(com.pkslow.springboot.aop.PkslowLogTime) execution(* *(..))")
public Object doAround(ProceedingJoinPoint joinPoint) throws Throwable {
log.info("------PkslowLogTime doAround start------");
MethodSignature methodSignature = (MethodSignature) joinPoint.getSignature();
// Get intercepted method details
String className = methodSignature.getDeclaringType().getSimpleName();
String methodName = methodSignature.getName();
// Measure method execution time
StopWatch stopWatch = new StopWatch(className + "- " + methodName);
stopWatch.start(methodName);
Object result = joinPoint.proceed();
stopWatch.stop();
// Log method execution time
log.info(stopWatch.prettyPrint());
log.info("------PkslowLogTime doAround end------");
return result;
@Around("@annotation(com.pkslow.springboot.aop.PkslowLogTime) execution(* *(..))")这个表达式很关键，如果不对，将无法正确识别；还有可能出现多次调用的情况。多次调用的情况可以参考：Stackoverflow
这里使用了Spring的StopWatch来计时。
通过maven build包：
$ mvn clean package
日志可以看到有对应的织入信息：

启动应用后访问接口，日志如下：
通过注解可以实现很多功能，也非常方便。而且注解还可以添加参数，组合使用更完美了。
