我要评论一、加入pom依赖
<dependency>
<groupid>org.springframework.boot</groupid>
<artifactid>spring-boot-starter-aop</artifactid>
</dependency>
二、切面类和注解
import java.lang.annotation.*;
@retention(retentionpolicy.runtime)
@target({elementtype.method})
@documented
public @interface aroundruntime {
string flag() default "";
}
import lombok.extern.slf4j.slf4j;
import org.aspectj.lang.proceedingjoinpoint;
import org.aspectj.lang.annotation.around;
import org.aspectj.lang.annotation.aspect;
import org.aspectj.lang.reflect.methodsignature;
import org.springframework.stereotype.component;
import java.lang.reflect.method;
import java.text.simpledateformat;
import java.util.date;
@aspect
@slf4j
@component
public class aroundaspect {
@around("@annotation(aroundruntime)")
public object aroundlog(proceedingjoinpoint point, aroundruntime aroundruntime) {
stringbuilder sb = new stringbuilder();
long start = 0;
try {
methodsignature signature = (methodsignature) point.getsignature();
method method = signature.getmethod();
sb.append("\n<===================================start===================================>\n");
sb.append("运行时间:>").append(getstringbydate(new date())).append("\n");
string methodname = method.getname();
sb.append("方法:> ").append(method.getdeclaringclass().getname() + "." + methodname).append("\n");
start = system.currenttimemillis();
object proceed = point.proceed();正常执行方法
return proceed;
} catch (runtimeexception e) {
sb.append("runtimeexception:>").append(e.getmessage()).append("\n");
throw e;
} catch (throwable throwable) {
sb.append("throwable:>").append(throwable.getmessage()).append("\n");
throw new runtimeexception("系统异常!");
}finally {
long end = system.currenttimemillis();
long time = end-start;
sb.append("运行时间 :> ").append("方法运行时间为"+(time/1000)+"." + (time%1000)+"秒").append("\n");
sb.append("<====================================end====================================>\n");
log.info(sb.tostring());
}
}
public static string getstringbydate(date date) {
try {
return new simpledateformat("yyyy-mm-dd hh:mm:ss").format(date);
} catch (exception e) {
e.printstacktrace();
}
return null;
}
}
三、执行方法
@aroundruntime
@getmapping("test")
public void test() throws exception {
thread.sleep(1000);
}
输出台结果
<===================================start===================================>
运行时间:>2024-08-05 19:34:47
方法:> com.qbh.controller.testcontroller.test
运行时间 :> 方法运行时间为1.15秒
<====================================end====================================>
