我正在使用 Struts2 jquery 创建依赖下拉菜单。问题是操作类中的 getLobList() 方法导致 hibernate 获取 lob 的所有数据。如果我删除该 getter 方法，则不会创建这些日志。为什么会出现这种情况，有什么办法可以解决吗？

最佳答案
我也遇到了同样的问题。
发生这种情况是因为负责创建 JSON 结果的 JSON 插件尝试序列化整个对象及其所有关系。
为了防止出现这种情况，我建议您为数据创建一个包装器(即，创建一个仅包含要使用的键和值的 LobJSONWrapper 类)，并返回包装器实例列表，而不是 Lob 实例。
您还可以阻止 JSON 插件序列化字段:请参阅“排除属性”here
关于java - Struts2 Hibernate(返回一个列表，导致 hibernate 从所有关系中获取数据)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/3376716/
