問題描述

  這兩天在編寫spring Boot整合jpa編寫實體類的時候，預設使用的命名策略是下劃線分隔的欄位命名,以下為具體異常資訊

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'appversion0_.app_version' in 'field list'
    at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
    at sun.reflect.NativeConstructorAccessorImpl

    at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45)
    at java.lang.reflect.Constructor.newInstance(Constructor.java:423)
    at com.mysql.jdbc.Util.handleNewInstance(Util.java:425)
    at com
 
.mysql.jdbc.Util.getInstance(Util.java:408)
    at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:943)
    at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:3970)
    at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:3906)
    at com.mysql.jdbc.MysqlIO.sendCommand(MysqlIO.java:2524)
 

經查證springdatajpa使用的預設策略是ImprovedNamingStrategy
所以修改配置下下hibernate的命名策略就可以了在application.properties檔案中加入
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
問題就可以圓滿解決了
