argument type mismatch

今天在进行编辑的时候，用断点调试去执行MyBeanUtils.copyBeanNotNull2Bean(tShzz, t);这行代码的时候，会报参数不匹配异常，不知道有哪位大神遇到过，   小弟 实体类中 日期的类似是 java.util.Date,   数据库中日期的类型为datetime，麻烦求大神指点。 TKS！！

你好，MyBeanUtils.copyBeanNotNull2Bean(tShzz, t)中的tShzz，t两个对象是不是同一个类？方便的话请将这两个类打包上传到这里我帮你看一下；
或者是将copyBeanNotNull2Bean换成copyBean2Bean方法试一下

您好！我换成copyBean2Bean 就可以了。 谢谢啊    可能是copyBeanNotNull2Bean不支持日期类型的转换
