SpringMVC/Hibernate项目实践一
 SpringMVC/Hibernate项目实践二
 SpringMVC/Hibernate项目实践三

第一步，引入SpringMVC实现控制层

pom.xml中引入依赖包：

web.xml参考内容：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

    <!-- 字符集过滤 -->
    <filter>

    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- 以下是 Spring MVC 的相关配置 -->
    <servlet>
        <servlet-name>spring</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>

        <!--配置容器在启动的时候就加载这个servlet并实例化 -->

        <url-pattern>/</url-pattern>
    </servlet-mapping>
    <!-- Spring MVC 的配置结束 -->

</web-app>

在src/main/resources中创建spring-mvc.xml
spring-mvc.xml参考代码：

<?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"
    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.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!-- 自动扫描且只扫描 @Controller -->
    <context:component-scan base-package="online.shixun.project"
        use-default-filters="false">
        <context:include-filter type="annotation"
            expression="org.springframework.stereotype.Controller" />
        <context:include-filter type="annotation"
            expression="org.springframework.web.bind.annotation.ControllerAdvice" />
    </context:component-scan>

    <!-- 对模型视图名称的解析,在请求时模型视图名称添加前后缀 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/" /> 
        <property name="suffix" value=".jsp" /> 
    </bean>

    <!-- 构建一个默认的 Serlvet 来额外的处理一切静态资源 -->
    <mvc:annotation-driven />
    <mvc:default-servlet-handler />

</beans>

创建包controller,创建controller的类

UserController.java
@Controller
public class UserController {

    @RequestMapping(value="hello")
    public String hello(){
        return "hello";
    }
}

在src/main/webapp/WEB-ING中创建views文件夹，在里面创建hello.jsp

%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
