@Table(name="table_name")
public class Entity{

}

2.实现 IDynamicTableName 接口

public class Entity   implements IDynamicTableName{

@Override
public String getDynamicTableName() {

    return “tableName”;
}
}

可以直接添加一个非数据库字段 使用 @Transient 注解  外部直接设置表名

 @Transient 
    private String tableName;

@Override
public String getDynamicTableName() {

    return  tableName;
}

IDynamicTableName 源码定义：
