1，你肯定是在写完controller层之后开始出问题，而且在此之前你的这个SSM项目和前端的还没有衔接好，所以你可以先把配置前端控制器的那部分先给注解掉，先不配置前端控制器，也就是下面这段代码

<servlet>
        <servlet-name>dispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring/*.xml</param-value>
        </init-param>

    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>
        &lt;!&ndash;先配置成*.do告诉spring容器只对.do结尾的请求进行拦截转发&ndash;&gt;
        &lt;!&ndash;因为涉及到前后端之间的地址传递，考虑使用/拦截所有的URL地址&ndash;&gt;
        &lt;!&ndash;如果是使用*.do不会存在静态资源无法访问的问题
            但是在使用拦截所有URL地址之后会出现静态资源无法加载(被拦截)
        &ndash;&gt;
        &lt;!&ndash;<url-pattern>/</url-pattern>&ndash;&gt;
        <url-pattern>/</url-pattern>
    </servlet-mapping>
