我想測(cè)量從傳入 HTTP 請(qǐng)求開(kāi)始到應(yīng)用程序到達(dá)某個(gè)點(diǎn)的時(shí)間。這兩個(gè)時(shí)間點(diǎn)都位于不同的類中。我將如何啟動(dòng)和停止這些不同類的計(jì)時(shí)器。我看不到使用 MeterRegistry 中的“命名”計(jì)時(shí)器的方法。我該怎么辦？

您可以使用 AOP，如下所示：
@Aspect
@Component
public class ControllerMonitor {
protected static final Logger LOGGER = LoggerFactory.getLogger(ControllerMonitor.class);
@Before("execution(public * com.demo.controller.*Controller.*(..))")
public void logBeforeAccess(JoinPoint joinPoint) {
if(joinPoint!=null){
String packageName = joinPoint.getSignature()!=null?joinPoint.getSignature().getDeclaringTypeName():"LOG-404";
LOGGER.info(". . .A request initiated from controller [" + packageName + "."+ getMethodSignature(joinPoint) + "]. . .");
}
}
@After("execution(public * com.demo.controller.*Controller.*(..))")
public void logAfterAccess(JoinPoint joinPoint) {
if(joinPoint!=null){
String packageName = joinPoint.getSignature()!=null?joinPoint.getSignature().getDeclaringTypeName():"LOG-404";
LOGGER.info(". . .Request from controller [" + packageName + "."+ getMethodSignature(joinPoint) + "] completed. . .");
}
}
@AfterThrowing(pointcut = "execution(public * com.demo.controller.*Controller.*(..))",throwing="exception")
public void logAfterThrowing(Exception exception){
LOGGER.error("Exception caught:"+ exception.getMessage());
}
private String getMethodSignature(JoinPoint joinPoint){
if(joinPoint!=null){
String methodName = joinPoint.getSignature().getName();
Object[] arguments = joinPoint.getArgs();
StringBuilder sb=new StringBuilder();
if(arguments!=null){
for (Object param: arguments) {
sb.append(param).append(",");
}
sb =(sb.length()>1)?sb.deleteCharAt(sb.length()-1):sb;
}
methodName = methodName+"("+new String(sb)+")";
return methodName;
}else{
return "LOG-405";
}
}
}

使用 AOP ......無(wú)需在每個(gè)類級(jí)別上進(jìn)行更改。這將是一個(gè)地方配置..
