Struts2 Hibernate（返回一个列表，导致 hibernate 从所有关系中获取数据）

Question

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？

JSP页面

<s:url id="remoteurl" action="getLists"/> 
<sj:select 
 href="%{remoteurl}" 
 id="lob" 
 onChangeTopics="reloadsecondlist" 
 name="lobId" 
 list="lobList"
 listKey="lobId"
 listValue="lobDescription"
 headerKey="-1" 
 headerValue="Please Select a Line of Business"
/>

Answer 1

我遇到了同样的问题。

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。

为了防止这种情况，我建议您为您的数据创建一个包装器（即，您创建一个仅包含您要使用的键和值的 LobJSONWrapper 类），并且返回包装器实例的列表，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”此处

Answer 2

您只需要从结果对象中删除您的服务对象，为此您需要在操作映射上编写代码。

<param name="excludeMethods">serviceObject</>
