Question

我无法在Tomcat7中获取数据库连接。我使用oracle linux作为操作系统。以下是我的数据库连接池配置。

server.xml中

<GlobalNamingResources>
<!-- Editable user database that can also be used by
     UserDatabaseRealm to authenticate users
-->
<Resource name="UserDatabase" auth="Container"
          type="org.apache.catalina.UserDatabase"
          description="User database that can be updated and saved"
          factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
          pathname="conf/tomcat-users.xml" />

<Resource name="jdbc/weblogin01"
    auth="Container"
    type="javax.sql.DataSource" 
    driverClassName="oracle.jdbc.OracleDriver"
    url="${resource.weblogin01.url}"
    username="${resource.weblogin01.username}"
    password="${resource.weblogin01.password}"
    initialSize="2"
    maxActive="20"
    maxIdle="10"
    minIdle="2"
    maxWait="-1" 
    testWhileIdle="true"
    timeBetweenEvictionRunsMillis="20000"
    validationQuery="select * from dual" />

<Resource name="jdbc/osswebportal"
    auth="Container"
    type="javax.sql.DataSource"
    driverClassName="oracle.jdbc.OracleDriver"
    url="${resource.osswebportal.url}"
    username="${resource.osswebportal.username}"
    password="${resource.osswebportal.password}" 
    initialSize="1"
    maxActive="20"
    maxIdle="10"
    maxWait="-1"
    testWhileIdle="true"
    timeBetweenEvictionRunsMillis="60000"
    validationQuery="select * from dual" />

的web.xml

 <resource-ref>
>         <res-ref-name>jdbc/osswebportal</res-ref-name>
>         <res-type>javax.sql.DataSource</res-type>
>         <res-auth>Container</res-auth>
>         <res-sharing-scope>Shareable</res-sharing-scope>
>     </resource-ref>
>     <resource-ref>
>         <res-ref-name>jdbc/weblogin01</res-ref-name>
>         <res-type>javax.sql.DataSource</res-type>
>         <res-auth>Container</res-auth>
>         <res-sharing-scope>Shareable</res-sharing-scope>
>     </resource-ref>

context.xml中

 <ResourceLink global="jdbc/weblogin01" name="jdbc/weblogin01" type="javax.sql.DataSource"/>
  <ResourceLink global="jdbc/osswebportal" name="jdbc/osswebportal" type="javax.sql.DataSource"/>

我还在tomcat的catalina.properties中定义了所有数据库细节

resource.osswebportal.url = JDBC：预言：瘦：@ test.com：1522：GPSP   resource.osswebportal.username =用户

resource.osswebportal.password =密码

resource.weblogin01.url = JDBC：预言：瘦：@ TEST2：1522：GSPS   resource.weblogin01.username =用户1

resource.weblogin01.password =密码

我还将jdbc jar放在tomcat的lib目录以及Applications的WEB_INF / lib目录中。

将Driver Jar文件放在服务器lib文件夹中，我认为这样可以解决您的问题。
