关于myabtis拦截器反射捕获异常问题

Question

myabtis自定义拦截器，如何捕获数据库连接异常，如下代码能否捕获

@Override

public Object intercept(Invocation invocation) {
    Object target = invocation.getTarget();
    SqlCount.increment();
    System.out.println("current sql count = " + SqlCount.getValue());
    long startTime = System.currentTimeMillis();
    StatementHandler statementHandler = (StatementHandler) target;
    try {
        return invocation.proceed();
    }catch (Exception e){
        logger.info("-------------------------------------");
        System.out.println(e.getClass());
        return "fail";
    }finally {
        long endTime = System.currentTimeMillis();
        long timeCount = endTime - startTime;
        logger.info("执行 SQL：[ ]执行耗时[ {} ms]", timeCount);
    }
}

我在本地测试，关闭数据库后此实现并不能捕获netException

有什么方式可以在拦截器层面进行数据库连接异常的捕获吗

你拦截StatementHandler 那怎么能行，拦截Executor那才稳妥
