我们正在将Struts 1.2项目从JDK 1.6迁移到1.8，并将应用程序服务器jboss5.1迁移到tomcat 8.5。因此，我们开始将JNDI数据源链接到tomcat，但似乎由于缺少错误而丢失了某些内容"java.sql.SQLException: No suitable driver"，但我添加了ojdbc驱动程序和配置。
数据库是Oracle 12C。
以下是完成此操作的步骤
-
在tomcat / conf下的context.xml中添加了数据库配置
<Resource name="jdbc/Test" auth="Container" type="javax.sql.DataSource" maxTotal="100" maxIdle="30" maxWaitMillis="10000" username="xxxxx" password="xxxxx" driverClassname="oracle.jdbc.OracleDriver" url="jdbc:oracle:thin:@xxxx:1527:xxxx" /> -
在{project} /WEB-INF/web.xml
下的web.xml中添加了数据源引用。<resource-ref> <description>Oracle Datasource</description> <res-ref-name>jdbc/Test</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> -
示例代码
public static void dbInit(String dataSourceRef) throws Exception { Context ctx = new InitialContext(); static DataSource ds = (DataSource) ctx.lookup("java:comp/env/" + dataSourceRef); } - 在tomcat / lib下添加了
ojdbc8.jar文件。

测试代码：
我正在尝试使用以下代码，并且工作正常，没有任何问题。但是通过JNDI连接仍然有问题。
try (Connection conn = DriverManager.getconnection(
"jdbc:oracle:thin:@localhost:1521:orcl","system","Password123")) {
if (conn != null) {
System.out.println("Connected to the database!");
} else {
System.out.println("Failed to make connection!");
}
} catch (SQLException e) {
System.err.format("SQL State: %s\n%s",e.getSQLState(),e.getMessage());
} catch (Exception e) {
e.printStackTrace();
}
