hibernate bug：ArrayIndexOutOfBoundsException on...

昨天给程序加上了2级缓存，今天打开查询统计页面，就报错： ava.lang.ArrayIndexOutOfBoundsException: 0 at org.hibernate.type.TypeHelper.disassemble(TypeHelper.java:146) at org.hibernate.cache.StandardQueryCache.put(StandardQueryCache.java:106) at org.hibernate.loader.Loader.putResultInQueryCache(Loader.java:2434) at org.hibernate.loader.Loader.listUsingQueryCache(Loader.java:2321) 才开始以为是java 版本换了的原因，最后直接搜索错误找到了这样个bug: ArrayIndexOutOfBoundsException on enabling cache for a Native SQL query 高版本的已经修订了这个错误，但换hibernate 版本肯定又一堆问题，所以在使用native sql query 的时候加上： q.setCacheable(false); 这样 就OK 了，2级缓存 语句缓存同意还是开启的，本地sql 查询禁用2级查询缓存就可以了 来源
