jeecg3.7.1切换用postgres数据库后报错：org.hibernate.exception.SQLGr...

honjo

3.7.1非maven版源码，通过修改dbconfig, jeecg_database properties 配置及spring-minidao.xml 配置，切换使用postgres数据库（postgres数据库通过工具从mysql初始库转过来的），但程序启动时老是报如下错:  org.hibernate.exception.SQLGrammarException: 错误: 字段 this_.id 不存在 。 请问是jeecg框架的bug，还是切换postgres数据库时还需要更新其它地方的配置信息？但切换用mysql时，启动时正常不报错。

数据库区分大小写了吧？

honjo

admin 你好，数据库名都是小写的，dbconfig 配置如下：
#postgresSQL
hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
validationQuery.sqlserver=SELECT 1
jdbc.url.jeecg=jdbc:postgresql://localhost:5432/jeecg371
jdbc.username.jeecg=postgres
jdbc.password.jeecg=123456
jdbc.dbType=postgres

spring minidao.xml 相关配置如下：
<!-- MiniDao动态代理类 -->
        <bean id="miniDaoHandler" class="org.jeecgframework.minidao.factory.MiniDaoBeanScannerConfigurer">
                <!-- 是使用什么字母做关键字Map的关键字 默认值origin 即和sql保持一致,lower小写(推荐),upper 大写 -->
                <property name="keyType" value="lower"></property>
                <!-- 格式化sql -->
                <property name="formatSql" value="false"></property>
                <!-- 输出sql -->
                <property name="showSql" value="false"></property>
                <!-- 数据库类型 mysql-->
                <property name="dbType" value="postgres"></property>
                <!-- dao地址,配置符合spring方式 -->
                <property name="basePackage" value="org.jeecgframework.web,com.jeecg"></property>
                <!-- 使用的注解,默认是Minidao,推荐 Repository-->
                <property name="annotation" value="org.springframework.stereotype.Repository"></property>
        </bean>

sysConfig 相关配置如下：
#database type for spring jdbc
jdbc.url.jeecg=postgres

postgres区分大小写，百度

honjo

admin 你好，问题应该是 jeecg中hinbernate 生成的 sql 对于postges中大写列名没有加双引号 导致，jeecg中hinbernate生成的sql 如下：
select this_.ID as ID45_0_, this_.CLASS_NAME as CLASS2_45_0_, this_.CREATE_BY as CREATE3_45_0_, this_.CREATE_DATE as CREATE4_45_0_, this_.CREATE_NAME as CREATE5_45_0_, this_.CRON_EXPRESSION as CRON6_45_0_, this_.IS_EFFECT as IS7_45_0_, this_.IS_START as IS8_45_0_, this_.RUN_SERVER as RUN9_45_0_, this_.RUN_SERVER_IP as RUN10_45_0_, this_.TASK_DESCRIBE as TASK11_45_0_, this_.TASK_ID as TASK12_45_0_, this_.UPDATE_BY as UPDATE13_45_0_, this_.UPDATE_DATE as UPDATE14_45_0_, this_.UPDATE_NAME as UPDATE15_45_0_ from t_s_timetask this_

postgers 根据mysql 转换过来的字段名与mysql一样，列名也是大写的，如postgres从mysql 转换过来的 t_s_timetask表的列名（都为大写）

这个问题的解决办法 能通过 初始化postgres数据库 字段名表名为小写， 或通过配置jeecg的中相应配置让hibernate生成的sql 正常匹配到postgres中的大写的列名吗（因为mysql库的初始脚本中好些表的字段是大写的）？

admin

设置下数据库不区分大小写，这种问题多百度
