Caused by: org.postgresql.util.PSQLException: 错误: 语法错误 在 “order“ 或附近的 位置：345_idea 报org.postgresql.util.psqlexception: :-程序员宅基地

技术标签： spring  java  postgresql  

此错误一般是由于postgres的数据库表字段名定义与关键字重名导致的错误；

我的表名有order，修改表名。

后来发现是因为改了表名，路由配置错误

spring.shardingsphere.sharding.tables.order.actual-data-nodes=ds$->{0..1}.order

改了名字

spring.shardingsphere.sharding.tables.db_order.actual-data-nodes=ds$->{0..1}.db_order

成功！
