JPA 默认会将实体中的 TABLE_NAME 转成小写如

@Entity
@Table(name = "EMPLOYEE")
public class Employee {

@Id
private String id;

会报:java.sql.SQLSyntaxErrorException: Table 'mysql.employee' doesn't exist 表名已经被转成了小写

可以添加一个策略解决此问题

package com.iron.config;

import org.hibernate.boot.model.naming.Identifier;
import org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl;
import org.hibernate.engine.jdbc.env.spi.JdbcEnvironment;

/**
* Created by Jimmy on 2020/3/13.
*/
public class UpperTableStrategy extends PhysicalNamingStrategyStandardImpl {

private static final long serialVersionUID = 1383021413247872469L;


@Override
public Identifier toPhysicalTableName(Identifier name, JdbcEnvironment context) {
// 将表名全部转换成大写
String tableName = name.getText().toUpperCase();

return name.toIdentifier(tableName);
}
}

application.yml 配置文件中添加相应的配置,启用上面的策略
