Question

java.lang.NoSuchMethodException: Unknown property

java.lang.RuntimeException: NoSuchMethodException: java.lang.NoSuchMethodException: Unknown property '23' on dynaclass 'org.apache.commons.beanutils.BasicDynaClass@1e91485'
这是什么错？

Answer 1

抛出的运行时异常，看问题应该是你定义的某个属性不存在或值类型不匹配，你可以看看这个提示中的‘23’，在你的程序的哪个地方，然后顺藤摸瓜，找找beanutil类中哪个类方法和这个‘23’有关联。

Answer 2

运行时异常.... 调用了没有定义的方法(java.lang.NoSuchMethodException:
)

具体代码贴出来啊

追问

追答

仔细查看beanutils这个类中的方法，应该是调用方法的属性出错

追问

那是apache 的 我引进来的 不能有问题 啊 其他位置我排序还好好的呢！
