proceedJoinPoint.proceed();

`proceedJoinPoint.proceed();` 是一个在 Aspect-oriented Programming (AOP) 中常见的表达式。它表示在切面中继续执行目标方法。当程序执行到该语句时,会继续执行目标方法,并将控制权交还给被拦截的方法。这样,切面可以在目标方法执行前后进行一些额外的操作或者修改返回结果。这种方式可以实现横切关注点的复用和解耦。请问还有其他问题吗?

这段代码中出现了一个空指针异常(NullPointerException)。
根据异常堆栈信息,异常发生在`com.datech.web.controller.system.TbappController`类的`remove`方法的第667行。
空指针异常通常是因为尝试在一个空对象上进行操作或访问了一个空引用导致的。你需要检查代码中的`TbappController`类的`remove`方法,在第667行附近,确认是否有可能出现空引用的情况。
可能的原因包括:
1. 某个对象没有正确初始化或赋值,导致为空。
2. 某个对象在使用之前被释放或销毁。
3. 某个方法返回了一个空对象。
你可以仔细检查代码,并使用调试工具来确定引发空指针异常的确切位置,进一步排查和修复问题。

这是一个Java异常信息,看起来是在获取日结单数据时出现了错误。具体原因需要查看代码并进行调试,可能是数据访问层或业务逻辑层出现了问题。建议先检查数据源配置是否正确,然后检查SQL查询语句是否正确,最后检查代码逻辑是否正确。如果还无法解决问题,可以考虑使用日志记录工具来查看更详细的错误信息,以便更好地定位和解决问题。
