在底层dao自己添加id=1

报错：java.lang.Long cannot be cast to java.lang.Integer
id对应的数据库的id，是不是这里定义为long，数据库的id不能用int啊！
不知道如何去排查这个错误！

还发现：数据库都查询了

DetachableCriteria(CriteriaImpl(com.pdcss.dbzx.survey.entity.SurveyProblems:this[][id=1])) Hibernate: select this_.id as id1_10_0_, this_.analysis as analysis2_10_0_, this_.answer as answer3_10_0_, this_.bank_id as bank_id4_10_0_, this_.createtime as createti5_10_0_, this_.img as img6_10_0_, this_.problem_name as problem_7_10_0_, this_.type as type8_10_0_, this_.typeStr as typeStr9_10_0_ from survey_problems this_ where this_.id=? 

但是为什么会报错？

已经解决，数据库改成bigint，跟long对应，就ok了！
