ContextLoaderListener监听器配置
<listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 防止Spring内存溢出监听器 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener>
DispatcherServlet前置控制器配置
<servlet> <!--springmvc框架默认自动找到/WEB-INF/springmvc-servlet.xml作为配置文件载入web工程中 这里手动设置位置--> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/springmvc-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported> </servlet>springmvc框架默认自动找到/WEB-INF/[servlet-name]-servlet.xml作为配置文件载入web工程中 这里手动设置位置为spring文件夹下的springmvc-servlet.xml，稍后再配置这个文件。
Servlet拦截设置
<servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee " version="3.1"> <!-- Spring配置 --> <!-- ================================================= --> <!--配置Spring IoC的配置文件路径 classpath相当于resources文件夹--> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/applicationContext.xml</param-value> </context-param> <!--Log4j配置--> <context-param> <param-name>log4jRefreshInterval</param-name> <param-value>60000</param-value> </context-param> <!--配置ContextLoaderListener初始化IOC容器--> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 防止Spring内存溢出监听器 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <!-- Spring mvc配置 --> <!-- ================================================= --> <!--DispatcherServlet前置控制器配置--> <servlet> <!--springmvc框架默认自动找到/WEB-INF/springmvc-servlet.xml作为配置文件载入web工程中 这里手动设置位置--> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/springmvc-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported> </servlet> <!--拦截内容：servlet映射设置--> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app> 3、applicationContext.xml配置在spring文件夹下建立applicationContext.xml
applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans "> <!--引入spring和其他整合的配置文件 比如spring-mybatis.xml等--> <import resource="classpath:spring/spring-*.xml"/> </beans>这里引入spring和其他整合的配置文件 比如spring-mybatis.xml等，接下来在spring文件夹下新建一个spring-mybatis.xml文件
4、spring-mybatis.xml配置
配置自动扫描，需要扫描到控制层和服务层，刚开始我这里写成了com.cr.mapper，结果导致控制器不能注入
<context:component-scan base-package="com.cr" />
