向数据库插入数据报错Error updating database. Cause: java.sql.SQLException: Incorrect string value: '\xE5\xA4\

之前连接数据库都没问题，可是今天新加一个表之后，向这个表中加入数据就报错：

2018-08-25 14:54:59.082  WARN 8136 --- [nio-8090-exec-7] .m.m.a.ExceptionHandlerExceptionResolver : Resolved exception caused by Handler execution: org.springframework.jdbc.UncategorizedSQLException:

 WHERE  (EXEC_STATUS = ? AND EXEC_PROGRESS = ? AND EXEC_TIME < ?)

后来找到原因：

之前我的数据库连接设置：jdbc:mysql://192.168.1.230:3306/trafficlight?useUnicode=true&characterEncoding=utf-8&useSSL=true

之后改为：jdbc:mysql://192.168.1.230:3306/trafficlight?useUnicode=true&characterEncoding=utf-8&useSSL=true

就OK了，注意将表的字符集和校验规则设置成UTF_8
