springMvc环境搭建
spring mvc 搭建的环境：
搭建一个maven工程（编辑环境是eclipse）

在maven工程集成spring

web.xml 中配置servlet
在默认情况下，如例子中一样， servlet-name - servlet.xml 默认放在/WEB-INF文件夹下
可以自己定义servlet文件的位置
<servlet> <servlet-name>helloWeb</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>helloWeb</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>
其中spring-mvc.xml为servlet的配置文件，在src/main/resources文件路径下。
spring-mvc.xml 文件中配置servlet的具体信息
<!-- 配置需要扫描的包 --> <context:component-scan base-package="com.test.controller" /> <!-- 配置视图解析器 --> <!--视图文件的 前缀为/WEB-INF/ 后缀为.jsp的文件 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/" /> <property name="suffix" value=".jsp" /> </bean>
前端jsp页面中用form表单提交
<form action="${pageContext.request.contextPath}/student/save" method="post"> <table> <tr><td>name</td><td><input type="text" name="name"></input></td></tr> <tr><td>age</td><td><input type="text" name="age"></input></td></tr> <tr><td colspan="2"><input type="submit" value="submit"></input></td></tr> </table> </form>
后端java 用一个实体类去接收
@RequestMapping(value="/save",method=RequestMethod.POST) public ModelAndView save(@ModelAttribute Student student){ ModelAndView view =new ModelAndView("result"); return view; }
参考文章：w3cSchool教程
采用spring框架写的一个简单的helloworld程序：
beans.xml配置
<bean id="helloword" class="com.tutorialspoint.HelloWorld"> <property name="message" value="Hello word111"></property> </bean>
HelloWorld实体类
public class HelloWorld { private String message; public String getMessage() { System.out.println("your mesage is:"+message); return message; } public void setMessage(String message) { this.message = message; } }
注册，加载，实例化，并应用bean
public static void main(String[] args) { //创建应用程序上下文环境，加载beans的配置，并初始化bean @SuppressWarnings("resource") ApplicationContext context=new ClassPathXmlApplicationContext("beans1.xml"); HelloWorld obj=(HelloWorld)context.getBean("helloword");//获取bean obj.getMessage();//调用bean的方法 }
