使用netbeans 搭建maven工程 整合spring springmvc框架

使用netbeans7.4

自带的tomcat7.0

所以jdk选择7.xx

然后等待生成空的工程，会缺一些文件夹，和文件，后续需要的时候补齐

然后修改pom.xml添加引用，直接覆盖dependencies标签就可以了，这里边添加了比较完整的引用，不会出现404错误

netbeans生成的maven工程没有web.xml文件 如何新建https://www.cnblogs.com/jnhs/p/9945362.html

然后新建srping的配置文件applicationContext.xml

下一步提示，选择要使用的项

什么也不选，直接把以下内容贴进去

    </bean>

存放于

继续新建controller包和controller类

根据一般习惯，把jsp放在WEB-INF/jsp文件夹中，我们新建一个结果页面，让controller跳转到这里

然后在web.xml添加spring的配置文件

 <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>
    <!-- 指定Spring Bean的配置文件所在目录。默认配置在WEB-INF目录下 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>WEB-INF/config/applicationContext.xml</param-value>
    </context-param>
    <!--SPRING MVC 配置-->
    <servlet>
        <servlet-name>spring</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>WEB-INF/config/spring-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/</url-pattern>
        <!--注意/和/*的区别-->
    </servlet-mapping>

以上基本就完成所有配置了

现在我们在controller中接收一下请求，并返回界面

然后运行，请求一下配置的url就可以看到跳转到新的页面

如果提示

HTTP Status 404 -

后边没了，这种情况是没有进入controller

这个情况可以使用调试模式，打一个类断点，你会发现，请求之后直接跳到404，没有进类断点，原因比较复杂：

根据错误信息来除错

有的是注解重名
有的是其他错误，比如缺少依赖

另一种是

HTTP Status 404 -你的路径

这种情况是跳转的页面不存在，没找到，一般就是路径写错了，这种情况就检查你的路径就可以了
