Tomcat上配置连接池{ connect error=Name [jdbc/OracleDB] is not bound in this Context. Unable to find [jdbc]}

. 在学习期间,从未实践过在tomcat上配置连接池,今天终于实现一次,在tomcat玩了一把,不知道你是否现在有和我一样的困境。废话少说直接上代码
 
java 
 public static Connection getConnection_tomcat() {	        Connection conn = null;	        try {	            Context initCtx = new InitialContext();	            Context ctx = (Context) initCtx.lookup("java:comp/env");	       	            Object obj = (Object) ctx.lookup("jdbc/OracleDB");	            javax.sql.DataSource ds = (javax.sql.DataSource) obj;	            return conn = ds.getConnection();	        }	        catch (Exception e) {	           	            System.out.println("connect error=" + e.getMessage());	            return null;	        }	    }

在tomcat->conf->server.xml

  <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" />		<!-- 在tomcat 配置连接池 -->					  	<Resource name="jdbc/OracleDB"  auth="Container"                         type="javax.sql.DataSource"  			  driverClassName="oracle.jdbc.driver.OracleDriver"    			  url=""  			  maxActive="50"    			  maxldle="10"    			  maxWait="5000"  			  username=""  			  password="" />    </GlobalNamingResources>

在tomcat->conf->context.xml 

<Context>    <WatchedResource>WEB-INF/web.xml</WatchedResource>	<!-- 在配置一个连接池 -->	<ResourceLink global="jdbc/OracleDB" name="jdbc/OracleDB" type="javax.sql.DataSource"/>  </Context>

这样就大功告成了!
