提示错误信息的意思是支持Tomcat运行的apr找不到。

总结网上的各种解决方案，得出两种可能的解决办法。

1.Tomcat中conf文件夹的web.xml配置需要如下所示

    <servlet-mapping>
        <servlet-name>default</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!-- The mappings for the JSP servlet -->
    <servlet-mapping>
        <servlet-name>jsp</servlet-name>
        <url-pattern>*.jsp</url-pattern>
        <url-pattern>*.jspx</url-pattern>
    </servlet-mapping>

2.在C:/WINDOWS/system32/或者Tomcat安装路径下的bin目录里复制粘贴tcnative-1.dll文件。
