springmvc类似于struts。是开源项目springframework下的一个框架。

１.jar包

依赖于spring所以需要导入spring的jar包。

我使用maven管理jar包

<!-- Spring -->        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-core</artifactId>            <version>${spring.version}</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-beans</artifactId>            <version>${spring.version}</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-context</artifactId>            <version>${spring.version}</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-context-support</artifactId>            <version>${spring.version}</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-web</artifactId>            <version>${spring.version}</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-webmvc</artifactId>            <version>${spring.version}</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-aop</artifactId>            <version>${spring.version}</version>        </dependency>

2.目录结构

３．基本配置

web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app version="3.0" 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_3_0.xsd">

　　　<!--加载全局变量，resources目录配置的bean可以在这里访问到-->     <!--<context-param>        <param-name>parentContextKey</param-name>        <param-value>guiceioc</param-value>    </context-param> -->

    <!--ContextLoaderListener监听器的作用就是启动Web容器时，自动装配ApplicationContext的配置信息-->    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>

　　<!--编码过滤器-->    <filter>        <filter-name>encodingFilter</filter-name>        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>        <!-- 开启异步支持        <async-supported>true</async-supported>-->        <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>encodingFilter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>    <!--GZIP压缩返回数据-->    <filter>        <filter-name>GzipFilter</filter-name>        <filter-class>org.eclipse.jetty.servlets.GzipFilter</filter-class>        <init-param>            <param-name>methods</param-name>            <param-value>GET,POST</param-value>        </init-param>        <init-param>            <param-name>mimeTypes</param-name>            <param-value>                text/html,text/plain,text/xml,application/xhtml+xml,text/css,application/javascript,application/json,image/svg+xml            </param-value>        </init-param>    </filter>    <filter-mapping>        <filter-name>GzipFilter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>

    <!--流程调度，springmvc核心-->    <servlet>        <servlet-name>ads</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        <load-on-startup>1</load-on-startup>        <!-- 开启异步支持        <async-supported>true</async-supported>-->    </servlet>    <servlet-mapping>        <servlet-name>ads</servlet-name>        <url-pattern>/</url-pattern>    </servlet-mapping>    <servlet-mapping>        <servlet-name>default</servlet-name>        <url-pattern>*.js</url-pattern>        <url-pattern>*.css</url-pattern>        <url-pattern>*.png</url-pattern>        <url-pattern>*.jpg</url-pattern>        <url-pattern>*.gif</url-pattern>        <url-pattern>*.ico</url-pattern>        <url-pattern>*.swf</url-pattern>    </servlet-mapping>    <error-page>        <error-code>404</error-code>        <location>/err404.jsp</location>    </error-page>    <error-page>        <error-code>405</error-code>        <location>/err405.jsp</location>    </error-page>    <error-page>        <error-code>500</error-code>        <location>/err500.jsp</location>    </error-page>    <error-page>        <error-code>503</error-code>        <location>/err503.jsp</location>    </error-page>    <welcome-file-list>        <welcome-file>/</welcome-file>    </welcome-file-list></web-app>
