日志切面;
日志的打印用切面拦截，切面中执行切点之前打印参数，执行切点之后打印返回的结果
方式一：用环绕通知把方法的请求，返回一起打印
@Pointcut("execution(* com.houbank.incoming.web.controller..*(..)) and @within(org.springframework.web.bind.annotation.Controller)")
private void anyAcesssAndResponseMethdod() {
}
@Around("anyAcesssAndResponseMethdod()")中打印请求参数，返回结果都在这一个环绕通知中
public Object doAround(ProceedingJoinPoint p) throws Throwable {
StringBuffer sb = new StringBuffer("类名:");
log.info(assemble(p,"doBefore"));
String targetName = p.getTarget().getClass().getName();
String methodName = p.getSignature().getName();
sb.append(targetName);
sb.append(".");
sb.append(methodName);
sb.append("()");
sb.append("--参数:");
Object result = null;
result = p.proceed();
try {
sb.append("serviceImpl_Result---"+ JSON.toJSONString(result));
sb.append("---serviceImpl_Result---END");
log.info(sb.toString());
} catch (Throwable e) {
log.error(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CommonLog.doAround()" + "-参数:" + sb + e.getMessage(),e);
}
log.info(assemble(p,"doAfter"));
return result;
}
方式二：用前置通知，后置通知分别打印请求，返回数
@Pointcut("execution(* com.houbank.incoming.service.impl.*.*(..))")
public void methodPointcut() {}
@Before("methodPointcut()")
public void before(JoinPoint joinPoint) {
Method method = ((MethodSignature) joinPoint.getSignature()).getMethod();
//查询不记录日志
if(method.getName().startsWith("select") || method.getName().startsWith("get") || method.getName().startsWith("query")) {
return;
}
StringBuilder sb = new StringBuilder();
sb.append(method.getDeclaringClass().getSimpleName()).append(".").append(method.getName()).append(" req:");
for(int i = 0; i < joinPoint.getArgs().length; i++) {
sb.append(joinPoint.getArgs()[i]);
}
log.info(sb.toString());
}
@AfterReturning(returning="rvt", pointcut="methodPointcut()")
public void after(JoinPoint joinPoint, Object rvt) {
Method method = ((MethodSignature) joinPoint.getSignature()).getMethod();
//查询不记录日志
if(method.getName().startsWith("select") || method.getName().startsWith("get") || method.getName().startsWith("query")) {
return;
}
log.info(method.getDeclaringClass().getSimpleName() + "."+ method.getName() + " resp:" + rvt);
}
然后异常通知打印异常时的日志
@AfterThrowing(value = "execution(* com.houbank.newapi.web.api..*.*(..))", throwing = "e")
public void doAfterThrowing(JoinPoint joinPoint, Throwable e) {
String errorMsg = assemble(joinPoint, "throwing") + e.getMessage();
log.error(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CommonLog.assemble()" + "-参数:" + errorMsg);
}
