部署 Tomcat 后 Java/Spring 应用卡住

Question

我使用 Java/Spring Mvc 网络应用开发比特币钱包。部署后，应用程序卡住了，什么也没有发生。我的意思是登录页面在本地主机中打开。之后，它应该在同步方面取得一些进展，并且按钮/下拉菜单应该处于 Activity 状态。没有错误。我得到的唯一日志是一些 WARNNING 和 INFO,

在database-context.xml文件中，提供了JNDI配置，

</beans>

在web.xml中，数据库引用如下，

<description>Spring Database</description>
    <resource-ref>
        <description>DB Connection</description>
        <res-ref-name>jdbc/spring</res-ref-name>
        <res-type>javax.sql.DataSource</res-type>
        <res-auth>Container</res-auth>
    </resource-ref>

在 Tomcat 中，Resource 信息由 conf/context.xml 提供，如下所示，

<Resource name="jdbc/spring" auth="Container" type="javax.sql.DataSource"
           maxActive="50" maxIdle="30" maxWait="10000"
           username="testname" password="testpassword"
           driverClassName="com.mysql.jdbc.Driver"
           url="jdbc:mysql://localhost:3306/wallet"/>

如果需要，我可以提供更多信息。问题是什么以及如何解决？

更新

我已经更改了 conf/context.xml 中的属性，如日志中所述:maxTotal 代替 maxActive 和 maxWaitMillis 代替 maxWait 并且 WARNING 消失了。它仍然卡住了。

Answer 1

您是否尝试过更改 conf/context.xml 中的属性，如日志中所述:maxTotal 而不是 maxActive 和 maxWaitMillis 而不是 maxWait？
