Question

我正在使用 Apache-ofbiz-13.07.03 。我用 ant 构建项目。我用mysql更改了数据库。当我想加载种子/演示数据时ant start，log显示错误。

***我正在使用mysql-connector-java-5.1.40-bin.jar进行jdbc连接

我的entityengin.xm就像

 <delegator name="default" entity-model-reader="main" entity-group-reader="main" entity-eca-reader="main" distributed-cache-clear-enabled="false">

     <group-map group-name="org.ofbiz" datasource-name="localmysql"/>
    <group-map group-name="org.ofbiz.olap" datasource-name="localmysqlolap"/>
    <group-map group-name="org.ofbiz.tenant" datasource-name="localmysqltenant"/>  

</delegator>

我的localmysql部分

我的服务器IP是 10.0.31.8

我想分享一下，我可以在本地计算机上成功运行此项目而不会有任何问题

Answer 1

请检查entityengine.xml是否配置正确。您可以在 -

找到该文件

/framework/entity/config/entityengine.xml

确保您已按照以下步骤操作 -

在mysql中创建数据库名称ofbiz，ofbizolap和ofbiztenant。

转到framework / entity / config / entityengine.xml并按如下所示进行更改。

<group-map group-name="org.ofbiz" datasource-name="localmysql"/>
<group-map group-name="org.ofbiz.olap" datasource-name="localmysqlolap"/>
<group-map group-name="org.ofbiz.tenant" datasource-name="localmysqltenant"/>

<group-map group-name="org.ofbiz" datasource-name="localmysql"/>
<group-map group-name="org.ofbiz.olap" datasource-name="localmysqlolap"/>
<group-map group-name="org.ofbiz.tenant" datasource-name="localmysqltenant"/>

<group-map group-name="org.ofbiz" datasource-name="localmysql"/>
<group-map group-name="org.ofbiz.olap" datasource-name="localmysqlolap"/>
<group-map group-name="org.ofbiz.tenant" datasource-name="localmysqltenant"/>

在datasource localmysql中，localmysqlolap，localmysqltenant更改了波纹管属性：

jdbc-username =“你的mysql用户名”

jdbc-password =“你的mysql用户密码”

希望这可能有所帮助（Y）

Answer 2

最后，我能够找到问题并能够解决我的问题。

jdbc-uri="jdbc:mysql://localhost/ofbiz?autoReconnect=true&amp;characterEncoding=UTF-8"

这就是这一行。每当我创建数据库模式时，我都将默认字符集设置为其他格式而不是 UTF-8

现在我可以连接我的数据库了。非常感谢你们所有人
