目前主流的Web MVC框架，除了Struts这个主力 外，还有Spring MVC，主要是由于Spring MVC配置比较简单，使用起来也十分明了，非常灵活，与Spring 集成较好，对RESTful API的支持也比struts要好。
MyBatis是ibatis的升级版，作为hibernate的老对手，它 是一个可以自定义SQL、存储过程和高级映射的持久层框架。
与hibernate的主要区别就是mybatis是半自动化的，而hibernate是全自动的，所以当应用需求越来越复杂的时候，自动化的sql显得比较笨拙。
由于前段时间接了个项目要用springmvc做，所以我抱着练手的态度，又玩起了整合框架的游戏。经常搭框架的人应该都清楚，框架搭建的核心就是配置文件。所以我主要贴下几个配置文件的代码。还是那句话，我都是写好配置文件之后，运行报错再加jar。这里列一下我用的jar包（应该是最少的）：
备注：上图有一些额外的jar，比如我用的数据库连接池是阿里巴巴的druid、日志框架式logback，所以引入了相关jar。关于这两个框架的使用和配置都是非常简单的，所以这里就不细说。
1.整合SpringMVC
springMybatis-servlet.xml：
[html] view plain copy
<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">
<context:component-scan base-package="com.alibaba.controller" />
<context:component-scan base-package="com.alibaba.service"/>
<mvc:mapping path="/" />
<mvc:mapping path="/user/**" />
<mvc:mapping path="/test/**" />
2.整合Mybatis
spring-dao.xml:
[html] view plain copy
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mybatis="http://mybatis.org/schema/mybatis-spring"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://mybatis.org/schema/mybatis-spring http://mybatis.org/schema/mybatis-spring.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<mybatis:scan base-package="com.alibaba.dao"/>
<context:property-placeholder location="classpath:configuration.properties"/>
1 5 1 60000 stat 60000 300000 <!--
SELECT 'x' true false false true 20 -->
3.web.xml整合SpringMVC和Mybatis
[html] view plain copy
default /js/* /css/* /images/* /fonts/* encodingFilter org.springframework.web.filter.CharacterEncodingFilter encoding UTF-8 forceEncoding true encodingFilter /* <!-- 初始化 DispatcherServlet时，该框架在 web应用程序WEB-INF目录中寻找一个名为[servlet-名称]-servlet.xml的文件，
并在那里定义相关的Beans，重写在全局中定义的任何Beans -->
springMybatis org.springframework.web.servlet.DispatcherServlet 1 springMybatis / contextConfigLocation /WEB-INF/config/spring-*.xml org.springframework.web.context.ContextLoaderListener DruidStatView com.alibaba.druid.support.http.StatViewServlet DruidStatView /druid/* 404 /error/404.jsp 500 /error/500.jsp
4.logback.xml日志配置
[html] view plain copy
%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
5.configuration.properties配置
[html] view plain copy
- jdbc.url=jdbc\:mysql\://localhost\:3306/druid?useUnicode\=true&characterEncoding\=UTF-8&zeroDateTimeBehavior\=convertToNull
- jdbc.username=root
- jdbc.password=123456
6.测试搭建是否成功，后台代码
首先是登录，用了加密，可以去掉
[java] view plain copy

import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import com.alibaba.model.User;
import com.alibaba.service.UserService;
import com.alibaba.util.RequestUtil;
/**

public class SystemController {
private final Logger log = LoggerFactory.getLogger(SystemController.class);
private UserService userService;
@RequestMapping(value = "/",method = RequestMethod.GET)
public String home() {
log.info("返回首页！");
return "index";
}
@RequestMapping(value = "/test/hello",method = RequestMethod.GET)
public String testHello() {
log.info("执行了testHello方法！");
return "testHello";
}
@RequestMapping(value = "/login",method = RequestMethod.POST)
public String testLogin(HttpServletRequest request,@RequestParam String username, @RequestParam String password) {
log.info("执行了testLogin方法！");
User user = userService.findUserByName(username);
if(user!=null){
if(user.getPassword().equals(DigestUtils.md5Hex(password))){
request.getSession().setAttribute("userId", user.getId());
request.getSession().setAttribute("user", username);
return "redirect:" + RequestUtil.retrieveSavedRequest();//跳转至访问页面
}else{
log.info("密码错误");
request.getSession().setAttribute("message", "用户名密码错误，请重新登录");
return "login";
}
}else{
log.info("用户名不存在");
request.getSession().setAttribute("message", "用户名不存在，请重新登录");
return "login";
}
}
}
select id, username , password from sysuser where username = #{username}
