mybatis 整合springMvc 一

简单的整体大概框架如下：

parent：是父类

dao: 层

impl: 实现服务层

service：服务层业务逻辑层

web ： mvc 层

----项目使用spring mvc 5

通过parent 对象项目进行统一的管理。

parent： pom.xml

这个引入依赖；

web 层：pom.xml 文件

web 层下：

web.xml 通用配置：

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>
  <!-- 解决post乱码 -->
	<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>
	</filter>
	<filter-mapping>
		<filter-name>CharacterEncodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
	<!-- springmvc的前端控制器 -->
	<servlet>
		<servlet-name>springmvc</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<!-- contextConfigLocation不是必须的， 如果不配置contextConfigLocation， springmvc的配置文件默认在：WEB-INF/servlet的name+"-servlet.xml" -->
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring/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>
</web-app>

在配置 springmvc-servlet.xml

<?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-3.2.xsd
                         http://www.springframework.org/schema/context
                        http://www.springframework.org/schema/context/spring-context-3.2.xsd
                        http://www.springframework.org/schema/mvc
                        http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <!-- 搜索spring控件 -->
    <context:component-scan base-package="com.fandong.it.weapon.controller"></context:component-scan>
    <context:component-scan base-package="com.fandong.it.weapon.serviceImpl"></context:component-scan>
     <!-- 开启springMVC的注解驱动，使得url可以映射到对应的controller -->  
    <mvc:annotation-driven/>
    <mvc:resources location="/css/" mapping="/css/**"></mvc:resources>
    <mvc:resources location="/*.html" mapping="/"></mvc:resources>
    <mvc:interceptors>  
         <!-- 国际化操作拦截器 如果采用基于（Session/Cookie）则必需配置 -->
         <bean  class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" >
            <property name="paramName" value="locale"/>
         </bean>  
    </mvc:interceptors>    
    <!-- 视图页面配置 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" >
        <property name="order">
         <value>1</value>
        </property>
        <property name="prefix">
            <value>/WEB-INF/jsp</value>
        </property>
        <property name="suffix">
            <value>.jsp</value>
        </property>
    </bean>
</beans>

验证mvc 适合可以正常，

/**
 * 
 */
package com.fandong.it.weapon.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

/**
 * @author fandong
 *
 */
@Controller
public class HelloController {

	@RequestMapping(value="/hello",method=RequestMethod.GET)
	public String sayHello(Model mode) {
		mode.addAttribute("message","hello");
		return "hello";
	}
}

在jsp下编写hello.jsp 文件

<%@ page language="java" contentType="text/html; charset=UTF-8" isELIgnored="false"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
    <span>${message}</span>
</body>
</html>
