我正在开发一个在 Tomcat 8.0 上运行的 JAX-RS 服务，当尝试访问我服务器上的 Mysql 数据库时出现异常。这是我得到的例外：

这是我的代码：context.xml 来配置 Mysql 连接
<Context>
<Resource name = "jdbc/vishipel"
auth="Container" type="javax.sql.DataSource"
maxActive="25" maxIdle="10" maxWait="10000"
maxTotal="50" removeAbandonedTimeout="300"
defaultAutoCommit="true"

username="cavnus" password="cavnus2016#"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/vishipel"/>
</Context>
在 web.xml 中定义资源引用
<resource-ref>
<description>MySQL DataSource</description>
<res-ref-name>jdbc/vishipel</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
这是我用来初始化 DataSource 的代码
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.sql.DataSource;
import org.apache.log4j.Logger;
public class Database {
static Logger logger = Logger.getLogger(Database.class);
private static DataSource ds = null;
static {
logger.info("Inside Database() static method...");
Context context = null;
try {
context = new InitialContext();
ds = (DataSource) context.lookup("java:comp/env/jdbc/vishipel");
} catch (NamingException e) {
// TODO: handle exception
logger.error("Unable to get DataSource..." + e);
e.printStackTrace();
}
}
public static DataSource getDataSource(){
return ds;
}
}
使用此代码在我的本地也可以使用。但是当我使用从我的项目导出的war文件部署到我的服务器上的Tomcat时，我得到了这个异常。
我的服务器正在运行 Window Server 2012 R2 Standard 64 位和在 Wamp Server 上运行的 MySql。
我已经将 mysql-connector-java-8.0.11.jar 复制到 Tomcat 的 lib 文件夹中或将其设置为类路径环境。但我仍然有例外
有人好心帮助并给我一个解决这个问题的方法。
太感谢了 ！
