不说了多了 直接上代码 首先是从程序的入口开始说：
web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- 设置session过期的时间 --> <session-config> <session-timeout>20</session-timeout> </session-config> <!-- 读取spring的配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:config/spring.xml;classpath:config/spring-myBatis.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <!-- 设置字符编码，将所有的字符编码同意设置为utf-8 --> <filter> <filter-name>filterEncoding</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>filterEncoding</filter-name> <url-pattern>/</url-pattern> </filter-mapping> <!-- 生成一次性验证码的servlet --> <servlet> <servlet-name>verifyCode</servlet-name> <servlet-class>com.longhang.tool.verifyCode.VerifyCodeServlet</servlet-class> </servlet> <!-- 将所有*.do的请求交给springMVC的DispatcherServlet来处理 --> <servlet> <servlet-name>DispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:config/springMVC-config.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>verifyCode</servlet-name> <url-pattern>/verifyCode</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>DispatcherServlet</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> </web-app>
springMVC的配置文件
<?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:p="http://www.springframework.org/schema/p" 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/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <!-- 配置自动扫描的包，让其扫描 com.longhang,controller下面的所有包 --> <context:component-scan base-package = "com.longhang.controller"></context:component-scan> <!-- 配置视图解析器 将视图逻辑名解析为/*.jsp --> <bean class = "org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name = "prefix" value = "/"></property> <property name = "suffix" value = ".jsp"></property> </bean> </beans>
spring.xml的配置
<?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 "> <context:property-placeholder location="classpath:config/druid.properties" /> <!-- 自动扫描(自动注入) --> <context:component-scan base-package = "com.longhang.service"></context:component-scan> </beans>
