org.springframework.beans.BeanUtils的一个demo.可以很优雅的实现将父类字段的值copy到子类中 下面例子的输出结果(子类使用父类的toString方法,有点意思吧): true Person{name='people'} import org.springframework.beans.BeanUtils; public class Test { public static void main(String[] args) { Person person =…

知识点 org.springframework.beans.BeanUtils与org.apache.commons.beanutils.BeanUtils都提供了copyProperties方法,作用是将一个Bean对象中的数据封装到另一个属性结构相似的Bean对象中 1)两者的copyProperties方法参数位置不同 org.springframework.beans.BeanUtils: copyProperties(sourceDemo, targetDemo) org.apache…

解决方法为将selenium-server-standalone-2.37.0.jar升级至selenium-server-standalone-2.41.0.jar即可. 下载地址:http://selenium-release.storage.googleapis.com/2.41/selenium-server-standalone-2.41.0.jar 这里是因为更新firefox所导致的问题,从27更新到28.0所致. 错误如下: WARN <init>, HHH000409: Us…

花费了一下午都没有搜索到相关解决方案的原因,一是我使用的 UnsatisfiedDependencyException 这个比较上层的异常(在最前面)来进行搜索, 范围太广导致没有搜索到,而且即便是有人提出是包扫描的问题,但是我spring的基础太差,所以也不知道该怎么操作, 然后这次又印证了我之前的那篇博客,即碰到异常一定要找到根异常,参考我之前的文章: java spring 等启动项目时的异常 或 程序异常的解决思路: 根异常一般在异常行的末尾,这次就是搜索末尾的 {@org.spring…
