org.springframework.aop.framework.AopProxyUtils 是Spring框架中的一个工具类,用于处理动态代理相关的操作。它提供了一些常用方法,可以用于获取代理对象的真实目标对象或者检查一个对象是否是动态代理对象。如果不使用 AopProxyUtils,你可能需要自己处理动态代理相关的逻辑,比如通过反射获取代理对象的真实目标对象。可以使用 AopProxyUtils.getSingletonTarget() 方法获取 targetSource 对象,或者使用 ReflectionUtils.makeAccessible(ctor) 方法来设置反射对象的可访问性。

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。
