Mybatis+Springmvc+Spring整合常用的配置文件

1.创建web项目

2.导入mabatis spring springnvc 需要的jar包

3.创建mybatis，spring，springmvc的配置文件

（1）web.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
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">

<!-- 告知javaEE容器，有哪些内容需要添加到上下文中去 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/classes/applicationContext.xml,
<!-- /WEB-INF/classes/mvc-servlet.xml -->
</param-value>
</context-param>

<!-- 加载LOG4J -->
<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>/WEB-INF/log4j.xml</param-value>
</context-param>

<context-param>
<param-name>log4jRefreshInterval</param-name>
<param-value>60000</param-value>
</context-param>

<!-- 动态设置项目的运行路径 -->
<context-param>
<param-name>webAppRootKey</param-name>
<param-value>ssm.root</param-value>
</context-param>

<!-- 配置静态资源 -->
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>/static/*</url-pattern>
</servlet-mapping>

<!-- 配置springmvc的前端控制器 -->
<servlet>
<servlet-name>mvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 默认情况下：DispatcherServlet会寻找WEB-INF下，命名规范为[servlet-name]-servlet.xml文件。如：在上例中，它就会找/WEB-INF/spring-servlet.xml
如果需要修改，需要在web.xml中的<servlet>标记中增加 <init-param>。。。 </init-param>：-->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/mvc-servlet.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>mvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

<!-- spring框架提供的字符集过滤器 -->
<!-- spring Web MVC框架提供了org.springframework.web.filter.CharacterEncodingFilter用于解决POST方式造成的中文乱码问题 -->
<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>
<!-- force强制，促使 -->
<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>

<!-- 登录过滤器-->
<filter>
<filter-name>loginFilter</filter-name>
<filter-class>com.cy.ssm.filter.LoginFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>loginFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

（2）mabatis配置文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org/DTD Config 3.0//EN"
    "http://mybatis.org/dtd/mybatis-3-config.dtd" >
<configuration>

</configuration>

（3）springmvc配置文件（servlet.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" xmlns:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

<!-- 启动注解，注册服务，如验证框架、全局类型转换器-->
<mvc:annotation-driven/>

<!-- 启动自动扫描 -->
<context:component-scan base-package="com.cy.ssm">
<!-- 制定扫包规则 ,只扫描使用@Controller注解的JAVA类 -->
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

<!-- 配置视图解析器 -->
<!--
prefix和suffix：查找视图页面的前缀和后缀（前缀[逻辑视图名]后缀），
比如传进来的逻辑视图名为WEB-INF/jsp/hello，则该该jsp视图页面应该存放在“WEB-INF/jsp/hello.jsp”； -->
<bean class="org.springframework.web.servlet.view.UrlBasedViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"></property>
<property name="prefix" value="/"></property> <!-- 我这里的视图直接放在WebRoot下的 -->
<property name="suffix" value=".jsp"></property>
</bean>
</beans>

（4）spring配置文件（applicationContext.xml）
