最近，同事在做一个功能，通过java程序将mysql中的一张表的数据同步到pgsql中，在同步过程中，插入到pgsql中出现了如下错误：
`### Error updating database. Cause: org.postgresql.util.PSQLException: ERROR: invalid byte sequence for encoding "UTF8": 0x00
在位置：unnamed portal parameter $13
The error may involve com.absin.modules.shop.dao.UprodCollectionProductDao.insert-Inline
The error occurred while setting parameters

和他一起通过查看一些资料，和咨询了公司的DBA定位到了问题，问题出现的原因是mysql的表中有些字段有转义字符 \0, 导致获取到数据后同步到pgsql中报错。
解决方法：在java中将从mysql中获取到的String类型的字段里的 \0 替换成 ""（空字符串）：str.replaceAll("\0",""); 然后再插入到pgsql中。
