使用WebSphere Liberty Profile 8.5设置数据源

标签: jdbc jndi websphere-liberty

我的网络应用程序从JNDI获取数据源:

javax.naming.InitialContext ctx = new javax.naming.InitialContext();
javax.sql.DataSource ds = (javax.sql.DataSource) 
    ctx.lookup("java:comp/env/jdbc/db");

在应用的WEB-INF/web.xml中,我有:

<resource-ref>
    <description>DataSource</description>
    <res-ref-name>jdbc/db</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
</resource-ref>

在应用的WEB-INF/ibm-web-bnd.xml中,我有:

<web-bnd
    xmlns="http://websphere.ibm.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://websphere.ibm.com/xml/ns/javaee http://websphere.ibm.com/xml/ns/javaee/ibm-web-bnd_1_0.xsd"
    version="1.0">
    <virtual-host name="default_host"/>
    <resource-ref name="jdbc/db" binding-name="jdbc/db"/>
</web-bnd>

在WebSphere Liberty Profile的server.xml中,我(保留相关部分):

<server description="new server">

    <featureManager>
        <feature>jsp-2.2</feature>
        <feature>jdbc-4.0</feature>
    </featureManager>

    <library id="oracle-lib">
        <fileset dir="lib" includes="ojdbc5_g.jar"/>
    </library>

    <dataSource jndiName="jdbc/db" jdbcDriverRef="oracle-driver" type="javax.sql.DataSource">
        <jdbcDriver libraryRef="oracle-lib" id="oracle-driver"/>
        <connectionManager numConnectionsPerThreadLocal="10" id="ConnectionManager" minPoolSize="1"/>
        <properties user="user" password="password"
                    url="jdbc:oracle:thin:@//db-server:1521/db"/>
    </dataSource>

</server>

当应用程序尝试从JNDI获取数据源时,它会失败,并显示以下错误:

CWNEN0030E: The @Resource factory encountered a problem getting
the object instance jdbc/oracle binding object.  The exception message was: 
failed to resolve jdbc/oracle to javax.sql.DataSource: 
javax.naming.NameNotFoundException: 
Intermediate context does not exist: jdbc/oracle

我在这里缺少什么?

WebSphere server.xml

<server>    
    <featureManager>
        <feature>jndi-1.0</feature>
        <feature>jdbc-4.1</feature>
    </featureManager>

    <httpEndpoint id="defaultHttpEndpoint"
                  host="localhost"
                  httpPort="9080"
                  httpsPort="9443" />

    <library id="oracle-lib">
        <fileset dir="lib" includes="ojdbc6_g.jar"/>
    </library>

    <dataSource jndiName="jdbc/oracle">
        <jdbcDriver libraryRef="oracle-lib"/>
        <properties.oracle user="orbeon" password="password"
                           url="jdbc:oracle:thin:@//localhost:1521/orbeon"/>
    </dataSource>

    <application name="orbeon" location="war/orbeon" type="war">
        <classloader commonLibraryRef="oracle-lib"/>
    </application>    
</server>

WEB-INF / IBM的Web-bnd.xml

<web-bnd version="1.0"
        xmlns="http://websphere.ibm.com/xml/ns/javaee"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://websphere.ibm.com/xml/ns/javaee http://websphere.ibm.com/xml/ns/javaee/ibm-web-bnd_1_0.xsd">
    <virtual-host name="default_host"/>
    <resource-ref name="jdbc/oracle" binding-name="jdbc/oracle"/>
</web-bnd>

WEB-INF / web.xml中

<resource-ref>
    <res-ref-name>jdbc/oracle</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
</resource-ref>

资源注入(而不是web.xml + ibm-web-bnd.xml):

@Resource(lookup = "jdbc/oracle")
DataSource ds;

我们在Liberty 8.5.5上使用DB2,我们在 server.xml

中使用
<dataSource id="db2" isolationLevel="TRANSACTION_READ_COMMITTED" jndiName="jdbc/db2" type="javax.sql.DataSource">
    <jdbcDriver>
        <library>
            <fileset dir="/usr/lib/java/ibm-db2-universal-driver" includes="db2jcc4.jar, db2jcc_license_cisuz.jar, db2jcc_license_cu.jar"/>
        </library>
    </jdbcDriver>

    <properties.db2.jcc databaseName="DB2T" portNumber="21020" serverName="db2t.lvm.de"/>
    <containerAuthData password="{xor}KzspMC04" user="tdvorg"/>
</dataSource>

也许有帮助。

在我的情况下,下面的解决方案适合我。

我在Eclipse中创建了一个名为“Resources”的“Generic project”。在这个项目中,我创建了一个文件function downloadFile () { var data = new blob([$scope.document.base64Code], {type: $scope.document.mimeType+';base64'}); var config = { data: data, filename: $scope.documentSaveAs ? $scope.documentSaveAs : $scope.document.FileName } fileSaver.saveAs(config); } ,内容如下:

dataSource.xml

我将这个文件拖放到Eclipse中进行服务器配置,或者在<server> <dataSource id="ccm" jndiName="jdbc/ccm" type="javax.sql.DataSource"> <jdbcDriver id="oracle-driver" libraryRef="oracle-lib"/> <connectionManager id="ConnectionManager" minPoolSize="1" numConnectionsPerThreadLocal="10"/> <properties.oracle password="password" url="jdbc:oracle:thin:@128.1.30.150:1521:ccmdes" user="ccm"/> </dataSource> <library id="oracle-lib"> <fileset dir="C:\Oracle\product\10.1.0\Client_1\jdbc\lib" includes="ojdbc14_g.jar"/> </library> <jdbcDriver id="oracle" libraryRef="oracle-lib"/> </server> 中创建一行:

server.xml

文件<include location="${shared.config.dir}/dataSource.xml"/> 是这样的:

server.xml
