分析思路：一看到Unhandled exception:
javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCException: could not execute statement，就知道是某个sql语句执行不了，具体是哪个sql呢，这个直接是看不出来的，只能根据业务代码判定，再看Caused by: java.sql.SQLException: ORA-01461: can bind a LONG value only for insert into a LONG column，百度下原因是插入的内容字符长度大于数据库存储长度转变成Long型插入数据库造成，具体不知道是哪个字段，然后只能对比数据筛选，连蒙带猜终于找到了那个类型为NVARCHAR2(2000)的字段，然后问题又来了，根据这个字段类型，按道理是在任何版本的任何字符集下都是可以支持2000个字符的，可实际是只能插入1000个字符，超过1000就报错，后来分析出来可能是项目问题，这个oracle库版本是Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production，而项目里使用的是ojdbc6-11.2.0.4.jar，在连接Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production时，项目是可以插入2000个字符的，所以我猜测可能是这个jar的版本和12.2的数据库不匹配导致。这个是个产线问题，从发现问题到最后找到问题总共花了一天一夜的时间，才最终解决。所以值得记录下。
