我把项目的web.xml中配置的

<servlet>

        <servlet-name>ReportServer</servlet-name>

        <servlet-class>com.fr.web.ReportServlet</servlet-class>

        <load-on-startup>0</load-on-startup>

    </servlet>

    <servlet-mapping>

        <servlet-name>ReportServer</servlet-name>

        <url-pattern>/ReportServer</url-pattern>

    </servlet-mapping>

注释掉

然后访问路径为：项目名/decision/view/report?viewlet=模板名称  访问成功
