hibernate 查询出来的结果 id 是int类型,xml文件配置的是int, 在jython 中调用hibernate 进行查询。字段的类型是java.lang.Long, 直接将id 传进去,报java.lang.Integer can not be cast to java.lang.Long 异常。将 id 进行强转,(Long)id,传进去,正常了。
你的代码估计是 jsonobject jo = （JSonObject)str;//将字符串强转成jsonobject，此时会上述错误。解决此错误的思路是：将一个字符串转成json对象，并不能使用强转，而应该使用相关的json包，它们提供了字符串和jsonobject、jsonarry等对象转换的api。google一下字符串和json对象互转，即可找到解决方案。

(In this code, the phrase String s is the type pattern.) The meaning is intuitive. The instanceof operator matches the target obj to the type pattern as follows: If obj is an instance of String, then it is cast to String and the value is assigned to the variable s. Rather than usin...
