基于SpringBoo防止接口重复提交代码示例

package com.example.demo2; import com.google.common.cache.Cache; import com.google.common.cache.CacheBuilder; import org.aspectj.lang.ProceedingJoinPoint; import org.aspectj.lang.annotation.Around; import org.aspectj.lang.annotation.Aspect; import org.aspectj.lang.annotation.Pointcut; import org.aspectj.lang.reflect.MethodSignature; import org.springframework.stereotype.Component; import java.lang.reflect.Method; import java.util.concurrent.TimeUnit; @Aspect @Component public class LockAspect { public static final Cache CACHES = CacheBuilder.newBuilder() .maximumSize(50) .expireAfterWrite(5, TimeUnit.SECONDS) .build(); @Pointcut("@annotation(com.example.demo2.LockCommit)&&execution(* com.example.demo2.*.*(..))") public void pointCut(){} @Around("pointCut()") public Object Lock(ProceedingJoinPoint joinPoint){ MethodSignature methodSignature = (MethodSignature) joinPoint.getSignature(); Method method = methodSignature.getMethod(); LockCommit lockCommit = method.getAnnotation(LockCommit.class); String key = lockCommit.key(); if(key!=null &&!"".equals(key)){ if(CACHES.getIfPresent(key)!=null){ throw new RuntimeException("请勿重复提交"); } CACHES.put(key,key); } Object object = null; try { object = joinPoint.proceed(); } catch (Throwable e) { e.printStackTrace(); } return object; } }
