springMVC+mybatis框架搭建

首先我們先要弄清搭建項目的一般流程，需要注意哪些方面，想要什么樣的效果，自己的功能有哪些？

（假設效果：項目目錄結構清晰，能夠查詢到本地數據庫中的內容。。）

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),

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

cn.springmvc.service（service接口）,

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

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

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

mapper（mybatis的mapper文件）

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

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項目管理的優勢）

查找依賴結構有個不錯的網站，http://search.maven.org/ 只要輸入包名即可查找引來關系

pom.xml(包依賴)

 3. 配置數據庫連接屬性 
 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="

</beans></pre>   conf/spring-mybatis.xml（spring與mybatis連接屬性） 
  <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="

</bean>

<!-- mybatis文件配置，掃描所有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為mybatis屬性 mapperLocations為所有mapper-->


<!-- spring與mybatis整合配置，掃描所有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></pre> 
  
 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;

}
}</pre>
 

 

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

 

package cn.springmvc.dao;


import cn.springmvc.model.User;
public interface UserDAO {

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



}</pre> 
  
 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);

}</pre> 
  
 

 

 

 
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);
}


}</pre> 
  
 

 

 

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

<!-- 映射map -->
<mappers>
</mappers>

</configuration></pre> 
  
 

 

 

 
 mapper/UserMapper.xml(mybatis的實現) 
   

 
 

 
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
 PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
";
<mapper namespace="cn.springmvc.dao.UserDAO">

     <insert id="insertUser" parameterType="User" keyProperty="id">
         insert into days_user(  
     state,
     nickname) 
     values 
     (        
     #{state},
     #{nickname})
     </insert>


</mapper></pre> 
  
 

 

 

 
 這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 {
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));
}

}</pre> 
  
 

 

 

 
 測試結果如圖： 
   

 
  
 即完成插入功能！ 
 8.  springMVC模塊搭建  
     web.xml（web功能配置） 
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="

<!-- 讀取spring配置文件 -->
<context-param>

</beans> 
   

 
 

 
 9.  log4j日志記錄搭建 
 

 
     conf/log4j.properties(日志記錄的配置文件) 
 
 ### 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</pre> 
  
 

 

 

 
 10.  測試運行 
 WEB-INF/jsp/index.jsp(測試文件) 
 

 
<%@ 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>歡迎你！！！</h1>
</body>
</html> 
   

 

 

 
 cn.springmvc.controller/UserComtroller.java(controller層控制) 
  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";
    }

} 
   

 
 

 
 

 
 將該項目部署到本地tomcat6中 
 右擊該項目選擇Run as，選擇Run on Server 
 選擇自己建立的tomcat6運行如圖： 
  
 控制臺打印出日志如圖（啟動成功）： 
  
 在瀏覽器中輸入：http://localhost:8080/springmvc/index.do 進行測試 
 效果如圖（返回成功）：
