IBM Worklight SQL適配器 - 無法連接到數據庫。無法加載JDBC驅動程序類 'com.mysql.jdbc.Driver'

我adapter.xmlIBM Worklight SQL適配器 - 無法連接到數據庫。無法加載JDBC驅動程序類 'com.mysql.jdbc.Driver'

<?xml version="1.0" encoding="UTF-8"?> 
<wl:adapter name="DbConnect" 

    <displayName>DbConnect</displayName> 
    <description>DbConnect</description> 
    <connectivity> 
     <connectionPolicy xsi:type="sql:SQLConnectionPolicy"> 
      <!-- Example for using a JNDI data source, replace with actual data source name -->

    </connectivity> 

    <!-- Replace this with appropriate procedures --> 
    <procedure name="select"/> 

</wl:adapter>

和適配器impl.js

var statement = WL.Server.createSQLStatement("select * from categorie"); 
    function select(statement) { 
     return WL.Server.invokeSQLStatement({ 
      preparedStatement : statement 
     }); 
    }

我下載的連接器.jar驅動程序，並找到它在server/lib文件夾中。我不明白，這可能是錯的..

編輯：下面我發佈的JavaScript當我運行的應用程序的工作燈移動瀏覽器模擬器

你在哪裏找到的連接器？你下載了哪一個？另外 - 嘗試刪除.jar並將其重新放回，它幫助我一次。 –

@nute我解決了這個問題。我編輯了url的端口（是3306而不是3036），我還在'select（）中更正了函數'select（statement）'' –

你能寫出這個答案作爲答案並將其標記爲已答覆嗎？謝謝。 –

我解決了這個問題控制檯的消息。我在.xml文件（是3306而不是3036）中編輯了url的端口，我還修正了select()中的函數select(statement)。

下面的兩個文件更正。

adapter.xml

<displayName>DbConnect</displayName> 
    <description>DbConnect</description> 
    <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://localhost:3306/test</url> 
       <user>root</user> 
       <password>mysql</password> 
      </dataSourceDefinition> 
     </connectionPolicy> 
     <loadConstraints maxConcurrentConnectionsPerNode="5" /> 
    </connectivity> 

    <!-- Replace this with appropriate procedures --> 
    <procedure name="remoteDbSize"/>

適配器impl.js

var statement = WL.Server.createSQLStatement("SELECT SUM(data_length + index_length) FROM information_schema.TABLES WHERE table_schema = \"test\" GROUP BY table_schema"); 
function remoteDbSize() { 
    return WL.Server.invokeSQLStatement({ 
     preparedStatement : statement, 
     parameters: [] 
    }); 
}
