mysql - Ofbiz:无法与 helperName [localmysql] 的数据库建立连接

Question

我正在使用 Apache-ofbiz-13.07.03。我用 ant 构建项目。我用 mysql 更改数据库。当我想加载种子/演示数据或ant 启动，日志显示错误。

*** 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>

还有我的localmysql部分

我的服务器 ip 是 10.0.31.8

我想分享一下，我可以在我的本地机器上成功运行这个项目，没有任何问题

Answer 1

请检查entityengine.xml配置是否正确。您可以在 -

/framework/entity/config/entityengine.xml

确保您已遵循以下步骤 -

1. 在 mysql 中创建数据库名称 ofbiz、ofbizolap 和 ofbiztenant。

2. 转到 framework/entity/config/entityengine.xml 并将其更改如下。

   <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"/>
   

并在数据源 localmysql、localmysqlolap、localmysqltenant 中更改以下属性:

jdbc-username="your mysql username"

jdbc-password="your mysql user password"

希望这会有所帮助(是)
