我的适配器.xml

<?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 -->
            <!-- <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:3036/test</url>
                <user>root</user>
                <password>root</password>
            </dataSourceDefinition>
        </connectionPolicy>
        <loadConstraints maxConcurrentConnectionsPerNode="5" />
    </connectivity>

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

</wl:adapter>

和适配器-impl.js

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

我下载了连接器驱动程序并在文件夹.jar中找到它server/lib。我不明白什么可能是错的。。

编辑：下面我在worklight移动浏览器模拟器中运行应用程序时发布控制台javascript的消息

我解决了这个问题。我在文件中编辑了 url 的端口.xml（是 3306 而不是 3036），我还更正select(statement)了select().

下面的两个文件更正。

适配器.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"/>

适配器-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: []
    });
}
