SSH 整合时 json报错 java.sql.SQLException: Positioned Update not supported
- 博客分类:

文章分类:Java编程 关键字: positioned update not supported异常解决备忘
今天在SSH项目中遇到运用JSON插件,产生如下异常:
该异常有两种解决方法:
第一:在struts.xml文件的配置中排除不要被JSON序列化的属性,例如:
其中functionsService就是不要被JSON序列化的属性。
第二:在Action文件中去除不要被JSON序列化的属性的get()方法,例如:
这样做functionsService同样不会被JSON序列化。

该异常有两种解决方法:
第一:在struts.xml文件的配置中排除不要被JSON序列化的属性,例如:
Java代码
- <action name="functions" class="getFunctionsAction" method="functions_getList">
- <result type="json">
- <param name="excludeProperties">functionsService</param>
- </result>
- </action>
<action name="functions" class="getFunctionsAction" method="functions_getList"> <result type="json"> <param name="excludeProperties">functionsService</param> </result> </action>
其中functionsService就是不要被JSON序列化的属性。
第二:在Action文件中去除不要被JSON序列化的属性的get()方法,例如:
Java代码
- public IFunctionsService getFunctionsService() {
- return functionsService;
- }
public IFunctionsService getFunctionsService() { return functionsService; }
这样做functionsService同样不会被JSON序列化。
