IBM Worklight - 使用IP地址而不是localhost时无法连接到数据库

标签： mysql ibm-mobilefirst worklight-adapters

我目前正在创建一个Worklight应用程序，它从我的计算机的MySQL数据库中检索一些数据。

当我尝试运行应用程序时，它无法连接到数据库。当我将数据库的URL更改为IP地址（192.168.6.1（我的计算机的本地主机））时，会发生错误。

当我通过调用worklight过程（地址是localhost）从我的计算机上测试它时它工作正常，但当我将URL更改为IP地址时，它显示错误：

以下是适配器XML的连接设置：

<?xml version="1.0" encoding="UTF-8"?>
...
...
  <connectivity>
    <connectionPolicy xsi:type="sql:SQLConnectionPolicy">
      <!-- Example for using a JNDI data source, replace with actual data source name -->
      <!-- <dataSourceJNDIName>java:/data-source-jndi-name</dataSourceJNDIName> -->

      <!-- Example for using MySQL connector, do not forget to put the MySQL connector library in the project's lib folder -->
      <dataSourceDefinition>
        <driverClass>com.mysql.jdbc.Driver</driverClass>
        <url>jdbc:mysql://192.168.6.1:3306/barcode</url>
          <user>root</user>

      </dataSourceDefinition>
    </connectionPolicy>
    <loadConstraints maxConcurrentConnectionsPerNode="5" />

我不知道您正在使用哪个数据库前端，但您需要转到用户创建/权限屏幕，并确保您已授予用户“root”权限以连接到{{1} }和localhost（全部），以便接受IP地址。

例如：%而不是/ root@%。

提到in slide #14 of the SQL adapter training module。

顺便说一句，您可以将其保留为localhost而不是IP地址（只要您在本地网络中进行测试）。它应该对设备无关紧要。你试过吗？
