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";
}
}
}
