很明显，类的和字段为空值，因为它们不存在于，但你可以看到的所有其他属性都是空的。我无法找到我做错了什么！selectedrenditionInfoFetchedContentSearchContentContent

任何指针都会非常有帮助。

答案 1

Java 中有两个 BeanUtils.copyProperties（parameter1， parameter2）。

一个是

org.apache.commons.beanutils.BeanUtils.copyProperties（Object dest， Object orig)

另一个是

org.springframework.beans.BeanUtils.copyProperties（Object source， Object target)

注意参数的相反位置。

答案 2

如果要从 searchContent 复制到内容，则代码应如下所示

BeanUtils.copyProperties(content, searchContent);

您需要在代码中反转上述参数。

从 API，

public static void copyProperties(Object dest, Object orig)
                           throws IllegalAccessException,
                                  InvocationTargetException)

参数：

dest - 属性已修改的目标 Bean

orig - 检索其属性的原产地豆
