When writing spring boot integrated jpa to write entity classes, the default naming strategy is to name fields separated by underscores. The following is the specific exception information

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.newInstance(NativeConstructorAccessorImpl.java:62) 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)

It has been verified that the default strategy used by springdatajpa is ImprovedNamingStrategy
, so modify the naming strategy of hibernate under the configuration and add
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming to the application.properties file. The PhysicalNamingStrategyStandardImpl
problem can be solved satisfactorily
