StringMVC程序简单实例
第一步：导入jar包
第二步，在WEB-INF文件夹下创建spring-servlet.xml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" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <!-- 注册aop功能 --> <aop:aspectj-autoproxy/> <!-- 自动扫面com.springmvc目录及其子目录下面所有类文件，自动注入所有带注解的类 --> <context:component-scan base-package="com.yxl.*" /> <!-- 处理请求response返回值，如下配置能正确返回字符串型返回值,如返回值为对象，则自动转为json --> <bean> <property> <list> <ref bean="mappingJacksonHttpMessageConverter" /><!-- json转换器 --> <ref bean="mappingStringHttpMessageConverter" /> </list> </property> </bean> <bean /> <bean /> <!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 --> <bean> <property value="/WEB-INF/jsp/" /> <property value=".jsp"></property> <property value="1"></property> </bean> <!-- spring文件上传编码 --> <bean p:defaultEncoding="utf-8" /> </beans>
第三步：在web.xml文件配置springmvc。
<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee " version="2.5"> <display-name>springmvc1</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <!-- 设置编码 --> <filter> <filter-name>characterEncodingFilter</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> <!-- 配置DispatchcerServlet --> <servlet> <servlet-name>Spring MVC Dispatcher Servlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <!-- 配置Spring mvc下的配置文件的位置和名称 --> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/spring-servlet.xml </param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <!-- 配置DispatchcerServlet 拦击路径'https://www.jb51.net/'所有访问都拦截--> <servlet-mapping> <servlet-name>Spring MVC Dispatcher Servlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
第四步：创建一个控制器。
