SSM集成

SSM集成
（1）建立Maven的Web項目
（2）先整合SS（Spring+SpringMVC）
    ①添加依賴

    </dependency>
    <!--spring的支持-->

    ②配置
        spring的配置文件

        springMVC的配置文件
            <!--掃描的包Controller-->
                <context:component-scan base-package="cn.itsource.ssm.controller"/>

                <!--啓用SpringMVC的註解支持-->
                <mvc:annotation-driven/>

                <!--靜態資源放行-->
                <mvc:default-servlet-handler/>

                <!--視圖解析器-->
                <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
                    <property name="prefix" value="/WEB-INF/views/"/>
                    <property name="suffix" value=".jsp"/>
                </bean>

                <!--文件上傳解析器-->
                <bean id="multipartResolver"
                      class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
                    <property name="maxUploadSize">
                        <value>${200*1024*1024}</value>
                    </property>
                </bean>

        web.xml配置文件
            <?xml version="1.0" encoding="UTF-8"?>
            <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
                     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                     xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
                                  http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
                     version="3.1">
              <!--Spring核心配置文件-->
              <context-param>
                <param-name>contextConfigLocation</param-name>
                <param-value>classpath:applicationContext.xml</param-value>
              </context-param>
              <!--SpringMVC的核心控制器-->
              <servlet>
                <servlet-name>dispatcher</servlet-name>
                <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
                <init-param>
                  <!--SpringMVC的配置文件-->
                  <param-name>contextConfigLocation</param-name>
                  <param-value>classpath:applicationContext-mvc.xml</param-value>
                </init-param>
                <!--項目啓動的時候建立這個Servlet-->
                <load-on-startup>1</load-on-startup>
              </servlet>
              <servlet-mapping>
                <servlet-name>dispatcher</servlet-name>
                <url-pattern>/</url-pattern>
              </servlet-mapping>

              <!--Spring啓動的監聽器-->
              <listener>
                <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
              </listener>

              <!--編碼過濾器-->
              <filter>
                <filter-name>encodingFilter</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>
              </filter>
              <filter-mapping>
                <filter-name>encodingFilter</filter-name>
                <url-pattern>/*</url-pattern>
              </filter-mapping>

            </web-app>

    ③測試
        Controller接收個請求，跳轉頁面
（3）再整個SM（Spring+Mybatis）

    ①依賴

    ②配置
        applicationContext.xml

    ③測試
