有配置文件吗 我想看看 我配置文件配置了过后就报错 不晓得哪里配置错了

hibernate方言包配了吗

<property name=“dialect”>org.hibernate.dialect.DmDialect</property>

加个这个属性看看

spring.jpa.hibernate.naming.physical-strategy=com.example.demo_jpa.CustomNamingStrategyConfig

import org.hibernate.boot.model.naming.Identifier;
import org.hibernate.engine.jdbc.env.spi.JdbcEnvironment;
import org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy;

public class CustomNamingStrategyConfig extends SpringPhysicalNamingStrategy {


    @Override
    public Identifier toPhysicalTableName(Identifier name, JdbcEnvironment jdbcEnvironment) {
        String tableName = name.getText().toUpperCase();
        return name.toIdentifier(tableName);


    }


    @Override
    public Identifier toPhysicalColumnName(Identifier name, JdbcEnvironment jdbcEnvironment) {
        String ColumnName = name.getText().toUpperCase();
        return name.toIdentifier(ColumnName);

    }

}
