maven构建springmvc项目

1.Eclipse中 NEW ->OTHER->Maven->maven project

2.选择项目路径

3.选择项目类型->next->输入groupid和artifactid->finished

4.新建好项目之后pom.xml添加springmvc、Jackson、taglib、jstl依赖，保存

             <version>2.5.0</version>
         </dependency>
     </dependencies>

5.配置build path->source

6.配置build path->libraries->jre system library 改成jdk1.6+版本

7.add library ->server runtime ->apache tomcat v7.0 (配置Tomcat的runtime包，避免运行项目时报缺少httpservletXXX的问题

8.把maven项目转为dynamic web module

右击项目->properties->project facets->dynamic web module 2.5+(3.0 是jdk7+的）同时修改对应的compiler级别，选择dynamic web module，java，js

9.设置部署文件路径列表 properties->deployment assembly

10.配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
                             http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         version="2.5" >

    <context-param>
        <param-name>webAppRootKey</param-name>
        <param-value>maven.example.root</param-value>
    </context-param>

    <!-- Spring的log4j监听器
    <listener>
        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
    </listener>-->

    <!-- 字符集 过滤器  -->
    <filter>
        <filter-name>CharacterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>CharacterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- Spring view分发器 -->
    <!-- 如要添加MVC驱动、注解检测、视图解析等。dispatcher-servlet.xml-->
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/dispatcher-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

11.配置dispatcher-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>

    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"

    <bean

        <property name="prefix" value="/WEB-INF/views/" />
        <property name="suffix" value=".jsp" />
    </bean>
    <bean

                <bean
                    class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
                    <property name="supportedMediaTypes">

                </bean>
            </list>
        </property>
    </bean>
</beans>

用maven构建的springmvc项目就搭建完成了。
