在做javaweb的过程中，搭建框架式比较头疼事情了，每次重新去搭建太浪费时间了，现在把框架搭建完成，可以在以后的项目中运用，节约开发成本.

**结构目录**  
springMVC+mybatis框架搭建  
1. 工程目录结构整理清楚  
2. 引入依赖包  
3. 配置数据库连接属性  
4. 配置spring配置文件  
5. java代码编写（model，dao，service层代码）  
6. mybatis配置  
7. junit测试插入功能  
8. springMVC模块搭建  
9. log4j日志记录搭建  
10. 测试运行

**springMVC+mybatis框架搭建**

在上一遍博客中以及讲诉了新建maven项目的流程，现在紧跟上一遍文章，接着搭建spring项目  
首先我们先要弄清搭建项目的一般流程，需要注意哪些方面，想要什么样的效果，自己的功能有哪些？  
（假设效果：项目目录结构清晰，能够查询到本地数据库中的内容。。）

**1. 工程目录结构整理清楚**

在src/main/java文件夹中，  
新建包  
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，  
新建包conf（存放配置文件），  
mapper（mybatis的mapper文件）

在src/test/java文件夹中，  
新建包cn.springmvc.test(存放测试文件)

在WEB-INF文件夹下新建jsp文件夹（存放jsp文件）

这样项目结构基本完成了

**2. 引入依赖包**

打开maven的pom文件，对本次开发所需使用的架包依次导入（maven项目管理的优势）

查找依赖结构有个不错的网站，[http://search.maven.org/][http_search.maven.org] 只要输入包名即可查找引来关系

**pom.xml(包依赖)**

**3. 配置数据库连接属性**

conf/ jdbc.properties（jdbc配置文件)

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

**4. 配置spring配置文件**

conf/spring.xml(spring配置文件的扫描)

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
    
        
        <context:property-placeholder location="classpath:conf/jdbc.properties"/>
    
        
        <context:component-scan base-package="cn.springmvc.service"/>
    </beans>

conf/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" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:util="http://www.springframework.org/schema/util" 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/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd">
    
        <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close" >
        <property name="driverClassName">
          <value>${jdbc_driverClassName}</value>
        </property>

        </property>
        <property name="password">
          <value>${jdbc_password}</value>
        </property>
        
        <property name="maxActive">
          <value>20</value>
        </property>
        
        <property name="initialSize">
          <value>1</value>
        </property>
        
        <property name="maxWait">
          <value>60000</value>
        </property>
        
        <property name="maxIdle">

        </property>
        
        <property name="removeAbandonedTimeout">
          <value>180</value>
        </property>
        
        <property name="connectionProperties">
          <value>clientEncoding=UTF-8</value>
        </property>
      </bean>
    
        
          <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean" p:dataSource-ref="dataSource" p:configLocation="classpath:conf/mybatis-config.xml" p:mapperLocations="classpath:mapper/*.xml"/>
    
       
     <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" p:basePackage="cn.springmvc.dao" p:sqlSessionFactoryBeanName="sqlSessionFactory"/>
    
       
      <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager" p:dataSource-ref="dataSource"/>
    </beans>

**5. java代码编写（model，dao，service层代码）**

cn.springmvc.model/User.java(用户基本信息)

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;
        }
    }

cn.springmvc.dao/UserDAO.java(dao操作接口)

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

cn.springmvc.service/UserService.java(service层接口)

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

cn.springmvc.service.impl/UserServiceImpl.java(service层接口实现)

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);
        }
    
    }

**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-3-config.dtd">
    <configuration>
            
        <typeAliases>
             <typeAlias alias="User" type="cn.springmvc.model.User"/> 
        </typeAliases>
    
        
        <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-3-mapper.dtd">
    <mapper namespace="cn.springmvc.dao.UserDAO">
    
             <insert id="insertUser" parameterType="User" keyProperty="id">
                 insert into days_user(  
             state,
             nickname) 
             values 
             (        
             #{state},
             #{nickname})
             </insert>
    
    </mapper>

这样就完成了基本插入用户的功能！

**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));
        }
    }

测试结果如图：

![这里写图片描述][20150408113515512]

即完成插入功能！

**8. springMVC模块搭建**

web.xml（web功能配置）

**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. 测试运行**

WEB-INF/jsp/index.jsp(测试文件)

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Insert title here</title>
    </head>
    <body>
    <h1>欢迎你！！！</h1>
    </body>
    </html>

cn.springmvc.controller/UserComtroller.java(controller层控制)

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