首先在web.xml中配置：

<error-page>
            <error-code>400</error-code>
            <location>/pages/common/exceptionError.jsp</location>
        </error-page>
        <error-page>
            <error-code>401</error-code>
            <location>/pages/common/exceptionError.jsp</location>
        </error-page>
        <error-page>
            <error-code>402</error-code>
            <location>/pages/common/exceptionError.jsp</location>
        </error-page>
        <error-page>
            <error-code>403</error-code>
            <location>/pages/common/exceptionError.jsp</location>
        </error-page>
        <error-page>
            <error-code>404</error-code>
            <location>/pages/common/exceptionError.jsp</location>
        </error-page>
        <error-page>
            <error-code>405</error-code>
            <location>/pages/common/exceptionError.jsp</location>
        </error-page>
        <error-page>
            <error-code>406</error-code>
            <location>/pages/common/exceptionError.jsp</location>
        </error-page>
        <error-page>
            <error-code>407</error-code>
            <location>/pages/common/exceptionError.jsp</location>
        </error-page>
        <error-page>
            <error-code>413</error-code>
            <location>/pages/common/exceptionError.jsp</location>
        </error-page>
        <error-page>
            <error-code>414</error-code>
            <location>/pages/common/exceptionError.jsp</location>
        </error-page>
        <error-page>
            <error-code>500</error-code>
            <location>/pages/common/exceptionError.jsp</location>
        </error-page>
     
        <error-page>
            <exception-type>java.lang.Exception</exception-type>
            <location>/pages/common/exceptionError.jsp</location>
    </error-page>

或者

<error-page>
    <exception-type>javax.servlet.ServletException</exception-type>
    <location>/pages/common/exceptionError.jsp </location>
    </error-page>

exceptionError.jsp页面内容：

    }
     
    }
    refresh();
    </script>
    </head>
    <body>
