参考文章 ：http://my.oschina.net/u/1011897/blog/199172 SpringMVC + mybatis 框架 一些配置记录
1. 工程目录结构
在src/main/java文件夹中
cn.springmvc.model -- 存放javabean
cn.springmvc.dao -- 存放spring与mybatis连接接口
cn.springmvc.service-- service接口
cn.springmvc.service.impl -- service接口的实现
cn.springmvc.controller -- 存放控制层controller

在src/main/resource文件夹中
conf -- 存放配置文件
mapper -- mybatis的mapper文件

在src/test/java文件夹中
cn.springmvc.test -- 存放测试文件

在WEB-INF文件夹下新建jsp文件夹
jsp -- 存放jsp文件

2. 引入依赖包
porm.xml

3. 配置数据库

jdbc_driverClassName=com.mysql.jdbc.Driver
jdbc_url=jdbc:mysql://localhost:3306/uic-fyp?useUnicode=true&characterEncoding=utf-8
jdbc_username=root
jdbc_password=

4. 配置spring配置文件, (都在 src/main/resource/conf目录下)
4.1 配置 spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:context="http://www.springframework.org ... ot%3B
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.springframework.org/schema/beans
      http://www.springframework.org ... 0.xsd
      http://www.springframework.org/schema/context
      http://www.springframework.org ... gt%3B
 
    <!-- 引入jdbc配置文件 -->
    <context:property-placeholder location="classpath:conf/jdbc.properties"/>
     
    <!-- 扫描文件（自动将servicec层注入） -->
    <context:component-scan base-package="cn.springmvc"/>
</beans>

4.2 配置 spring-mybatis.xml (spring 与 mybatis连接属性)

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

    http://www.springframework.org ... 2.xsd
    http://www.springframework.org/schema/util 
    http://www.springframework.org ... gt%3B
 
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init"
    destroy-method="close" >
    <property name="driverClassName">

    </property>
    <!-- 连接池最大使用连接数 -->
    <property name="maxActive">

      <value>clientEncoding=UTF-8</value>
    </property>
  </bean>
     
    <!-- mybatis文件配置，扫描所有mapper文件 -->
      <bean id="sqlSessionFactory"
          class="org.mybatis.spring.SqlSessionFactoryBean"
          p:dataSource-ref="dataSource"
          p:configLocation="classpath:conf/mybatis-config.xml"
          p:mapperLocations="classpath:mapper/*.xml"/><!-- configLocation为mybatis属性 mapperLocations为所有mapper-->
       
   <!-- spring与mybatis整合配置，扫描所有dao -->

  <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager"
        p:dataSource-ref="dataSource"/>
</beans>

5. 编写java 代码
Model

package cn.springmvc.model;
 
 
/**
 * 用户表
 */
public class User {
 
    private int id;
    private int state;
    private String nickname;
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public int getState() {
        return state;
    }
    public void setState(int state) {
        this.state = state;
    }
    public String getNickname() {
        return nickname;
    }
    public void setNickname(String nickname) {
        this.nickname = nickname;
    }
}

Dao

import cn.springmvc.model.User;
 
 
public interface UserDAO {
 
    /**
     * 添加新用户
     * @param user
     * @return
     */
    public int insertUser(User user); 
}

Service

package cn.springmvc.service;
 
import cn.springmvc.model.User;
 
 
public interface UserService {
 
    public int insertUser(User user);
}

ServiceImpl

package cn.springmvc.service.impl;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
 
import cn.springmvc.dao.UserDAO;
import cn.springmvc.model.User;
import cn.springmvc.service.UserService;
 
 
@Service
public class UserServiceImpl implements UserService{
 
    @Autowired
    private UserDAO userDAO;
     
    @Override
    public int insertUser(User user) {
        // TODO Auto-generated method stub
        return userDAO.insertUser(user);
    }
 
}

Controller

package cn.springmvc.controller;
 
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
 
@Controller
@RequestMapping("/")
public class UserController {
 
    @RequestMapping("index")
    public String index(){
        return "index";
    }
     
}

6. mybatis 配置
conf/mybatis-config.xml(mybatis配置的基本文件)

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration 
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis ... gt%3B
<configuration>
        <!-- 命名空间 -->
    <typeAliases>
         <typeAlias alias="User" type="cn.springmvc.model.User"/> 
    </typeAliases>
 
    <!-- 映射map -->
    <mappers>
    </mappers>
</configuration>

mapper/UserMapper.xml(mybatis的实现)

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
 PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis ... gt%3B
<mapper namespace="cn.springmvc.dao.UserDAO">
            
         <insert id="insertUser" parameterType="User" keyProperty="id">
             insert into days_user(  
         state,
         nickname) 
         values 
         (        
         #{state},
         #{nickname})
         </insert>
          
</mapper>

7. junit 测试插入功能
cn.springmvc.test/UserTest.java(用户测试模块)

package cn.springmvc.test;
 
import org.junit.Before;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
 
import cn.springmvc.model.User;
import cn.springmvc.service.UserService;
 
 
 
public class UserTest {
 
private UserService userService;
     
    @Before
    public void before(){                                                                    
        @SuppressWarnings("resource")
        ApplicationContext context = new ClassPathXmlApplicationContext(new String{"classpath:conf/spring.xml"
                ,"classpath:conf/spring-mybatis.xml"});
        userService = (UserService) context.getBean("userServiceImpl");
    }
     
    @Test
    public void addUser(){
        User user = new User();
        user.setNickname("你好");
        user.setState(2);
        System.out.println(userService.insertUser(user));
    }
}

8. springMVC 模块搭建
** web.xml（web功能配置）**

<?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/jav ... ot%3B

</beans>

9. log4j日志记录搭建
conf/log4j.properties(日志记录的配置文件)

### set log levels ###
#log4j.rootLogger = debug , stdout , D , E
log4j.rootLogger = debug , stdout , D
 
###  output to the console ###
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
#log4j.appender.stdout.layout.ConversionPattern = %d{ABSOLUTE} %5p %c{ 1 }:%L - %m%n
log4j.appender.stdout.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [%c]-[%p] %m%n
 
### Output to the log file ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = ${springmvc.root}/WEB-INF/logs/log.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = DEBUG 
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n
 
### Save exception information to separate file ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = ${springmvc.root}/WEB-INF/logs/error.log 
log4j.appender.D.Append = true
log4j.appender.D.Threshold = ERROR 
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n

10. WEB-INF/jsp/index.jsp(测试文件)
