旅游后台管理系列——SSM框架Web表现层

整合web层

表现层就一个springmvc框架！由springmvc来管理controller，配置文件内容有：

1. 需要扫描controller
2. 配置注解驱动
3. 配置视图解析器

配置完spring-mvc之后不要忘了在web.xml中添加配置：

1. Spring容器的配置
2. Springmvc前端控制器的配置
3. Post乱码过滤器

1）配置spring-mvc.xml文件

<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"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-4.2.xsd
        http://www.springframework.org/schema/aop 
		http://www.springframework.org/schema/aop/spring-aop-4.2.xsd
		http://www.springframework.org/schema/tx
		http://www.springframework.org/schema/tx/spring-tx.xsd
		http://www.springframework.org/schema/mvc 
 		http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">
 		
   	
  	<context:component-scan base-package="com.oak.xiyuyou.controller"/>
  	
    
    <mvc:annotation-driven/>
    
    
    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        
        <property name="prefix" value="/WEB-INF/"/>
        
        <property name="suffix" value=".jsp"/>
    bean>
beans>

我们springmvc.xml文件中配置的扫描包是com.taotao.controller，因此我们需要创建这么一个目录，并且从视图解析器的配置中可以看出，我们还要在WEB-INF目录下新建一个jsp目录：

2）在web.xml中配置前端控制器和编码过滤器

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

    <welcome-file>index.htmlwelcome-file>
    <welcome-file>index.htmwelcome-file>
    <welcome-file>index.jspwelcome-file>
    <welcome-file>default.htmlwelcome-file>
    <welcome-file>default.htmwelcome-file>
    <welcome-file>default.jspwelcome-file>

      <filter>
        <filter-name>encodingFilterfilter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>
        <init-param>

    <filter-mapping>

        <url-pattern>/*url-pattern>

       <servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
       <init-param>
