最近开始学SSM框架了,在学习搭建运行环境和配置文件时,花了好久,有很多次都出了异常,最后终于跑通了一个简单的登录功能.现将各种XML文件记录下来以便日后查看.
一.Web.XML
<?xml version="1.0" encoding="UTF-8"?> <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" version="3.0"> <display-name>SSMTest</display-name> <welcome-file-list> <welcome-file>Login.html</welcome-file> </welcome-file-list> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>/js/*</url-pattern> <url-pattern>/css/*</url-pattern> <url-pattern>/images/*</url-pattern> <url-pattern>/fonts/*</url-pattern> <url-pattern>*.jpg</url-pattern> </servlet-mapping> <!-- 统一配置字符集 --> <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> <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> <!-- 配置DispatcherServlet --> <servlet> <!--名字与 [servlet-name]-servlet.xml 中的servlet-name 相同 --> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/config/springmvc-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- 配置上下文路径 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/config/ssm-*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 配置数据源 --> <servlet> <servlet-name>DruidStatView</servlet-name> <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>DruidStatView</servlet-name> <url-pattern>/druid/*</url-pattern> </servlet-mapping> </web-app>
