java.lang.Object

com.fr.stable.db.extra.interceptor.impl.EmptyDBInterceptor

com.fr.stable.db.extra.interceptor.impl.ClobLengthFixForOracle9iInterceptor

所有已实现的接口:

DBInterceptor, com.fr.third.org.hibernate.Interceptor

public class ClobLengthFixForOracle9iInterceptor
extends EmptyDBInterceptor

Created by loy on 2018/8/3. 转换clob类型字符串长度的拦截器，在oracle 9i版本，clob类型存长度1000-2000的字符串会有错误：ORA-01461 原理：在插入和更新时，若字段长度在1000-2000之间，就填充空格至2000长度以上
