首先咱們先要弄清搭建項目的通常流程，須要注意哪些方面，想要什麼樣的效果，本身的功能有哪些？html

（假設效果：項目目錄結構清晰，可以查詢到本地數據庫中的內容。。）java

1.  工程目錄結構整理清楚

在src/main/java文件夾中，新建包cn.springmvc.model(存放javabean),mysql

                                            cn.springmvc.dao（存放spring與mybatis鏈接接口）,web

                                            cn.springmvc.service（service接口）,ajax

                                            cn.springmvc.service.impl（service接口的實現），spring

                                            cn.springmvc.controller（存放控制層controller）sql

在src/main/resource文件夾中，新建包conf（存放配置文件），數據庫

                                                   mapper（mybatis的mapper文件）apache

在src/test/java文件夾中，新建包cn.springmvc.test(存放測試文件)json

在WEB-INF文件夾下新建jsp文件夾（存放jsp文件）

這樣項目結構基本完成了

2.  引入依賴包

打開maven的pom文件，對本次開發所需使用的架包依次導入（maven項目管理的優點）

查找依賴結構有個不錯的網站 只要輸入包名便可查找引來關係

pom.xml(包依賴)

3. 配置數據庫鏈接屬性

conf/ jdbc.properties（jdbc配置文件)

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

4.  配置spring配置文件

    conf/spring.xml(spring配置文件的掃描)

 

<?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">

    <!-- 引入jdbc配置文件 -->
    <context:property-placeholder location="classpath:conf/jdbc.properties"/>
    
    <!-- 掃描文件（自動將servicec層注入） -->
    <context:component-scan base-package="cn.springmvc.service"/>
</beans>

  conf/spring-mybatis.xml（spring與mybatis鏈接屬性）

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

    <!-- mybatis文件配置，掃描全部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爲mybatis屬性 mapperLocations爲全部mapper-->
      
   <!-- spring與mybatis整合配置，掃描全部dao -->
 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"
        p:basePackage="cn.springmvc.dao" 
        p:sqlSessionFactoryBeanName="sqlSessionFactory"/>
 
   <!-- 對數據源進行事務管理 -->
  <bean id="transactionManager" 
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager"
        p:dataSource-ref="dataSource"/>
</beans>

5.  java代碼編寫（model，dao，service層代碼）

   cn.springmvc.model/User.java(用戶基本信息)

 

package cn.springmvc.model;


/**
 * 用戶表
 */
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操做接口)

 

 

package cn.springmvc.dao;

import cn.springmvc.model.User;


public interface UserDAO {

	/**
	 * 添加新用戶
	 * @param user
	 * @return
	 */
	public int insertUser(User user);
	
}

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

package cn.springmvc.service;

import cn.springmvc.model.User;


public interface UserService {

	public int insertUser(User user);
}

 

cn.springmvc.service.impl/UserServiceImpl.java(service層接口實現)

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>
        <!-- 命名空間 -->
    <typeAliases>
         <typeAlias alias="User" type="cn.springmvc.model.User"/> 
    </typeAliases>

    <!-- 映射map -->
    <mappers>
    </mappers>
</configuration>

mapper/UserMapper.xml(mybatis的實現)

<?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>

樣就完成了基本插入用戶的功能！

7.  junit測試插入功能

cn.springmvc.test/UserTest.java(用戶測試模塊)

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 {
pvate 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));
	}
}

測試結果如圖：

maven+springMVC+mybatis+junit詳細搭建過程

即完成插入功能！

8.  springMVC模塊搭建 

    web.xml（web功能配置）

9.  log4j日誌記錄搭建

 

    conf/log4j.properties(日誌記錄的配置文件)

 

### 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
