Spring MVC 环境搭建（maven+SpringMVC+mybatis+Freemarker）

一、准备工作

　　1.Eclipse Java EE IDE（4.4.1）

　　2.JDK

　　3.Tomcat

　　4.Maven maven安装指南

二、构建工程

　　1.file->new->Project

　　2.next

　　3. next

　　4.next

　　5.finish

　　　　工程目录如下

三、完善项目

　　　　首先，完善目录，增加重要的source Folder，这个不是简单的Floder,这些文件夹是会参与编译的。

　　　　增加src/main/java，src/test/resources，src/test/java目录。让目录变成标准的maven结构

　　　　说明：src/test/resources 通过添加source Folder 添加

　　　　　　 src/main/java，src/test/java 通过Navigator中 new folder 添加

　　　　window->show view->Navigator

　　　　标准目录为：

四、工程属性设置

　　　　1.工程右键->Properties->Deployment Assembly

　　　　　　修改为

五、SpringMVC工程搭建（MyBatis+Freemarker）

　　1.完善工程目录结构　　

　　　　在src/main/java文件夹中，新建包

　　　　　　 com.operate.command(存放传入的参数javabean)，

　　　　　　 com.operate.dto(存放数据库取出的数据的javabean),

　　 com.operate.dao（存放spring与mybatis连接接口）,

　　　　　　 com.operate.persistence(存放中间持续的javabean)，

com.operate.service（service接口）,

　　　　　　 com.operate.service.impl（service接口的实现），

　　　　　　 com.operate.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

　　　　　　com.operate.test(存放测试文件)

　　　　在WEB-INF文件夹下新建ftl文件夹（存放freemarker文件）

　　　　这样项目结构基本完成了，如下图：

　　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/ 只要输入包名即可查找引来关系

　　　　pom.xml

3.配置数据库连接属性

conf/ jdbc.properties（jdbc配置文件)

SQLServver

url=jdbc:sqlserver://localhost:1433；DatabaseName=user
user=root
password=root
driver=com.microsoft.sqlserver.jdbc.SQLServerDriver

MySQL

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/mydays?useUnicode=true&characterEncoding=utf-8
user=root
password=root

conf/spring-mybatis.xml（spring与mybatis连接属性）

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

4.java代码编写

com.operate.dto/User.java

package com.operate.dto;

public class User {
	private String name;
	private String photo;
	public String getPhoto() {
		return photo;
	}
	public void setPhoto(String photo) {
		this.photo = photo;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
}

com.operate.dao/UserDao.java

1 package com.operate.dao;
2 
3 import com.operate.dto.User;
4 
5 public interface UserDao {
6     public User getUser();
7 }

com.operate.service/UserService.java

1 package com.operate.service;
2 
3 import com.operate.dto.User;
4 
5 public interface UserService {
6     public User getUser();
7 }

com.operate.service.impl/UserServiceImpl.java

 1 package com.operate.service.impl;
 2 
 3 import org.springframework.beans.factory.annotation.Autowired;
 4 import org.springframework.stereotype.Service;
 5 
 6 import com.operate.dao.UserDao;
 7 import com.operate.dto.User;
 8 import com.operate.service.UserService;
 9 
10 @Service
11 public class UserServiceImple implements UserService {
12 
13     @Autowired
14     private UserDao userDAO;
15     
16     @Override
17     public User getUser() {
18         // TODO Auto-generated method stub
19         return userDAO.getUser();
20     }
21 
22 }

5.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 type="com.operate.dto.User" alias="UserInfo"/>
	</typeAliases>
    <!-- 映射map -->
    <mappers>
    </mappers>
</configuration>

mapper/sql-map-User.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="com.operate.dao.UserDao">
    <select id="getUser" resultType="UserInfo">
        SELECT 
            *        
　　　　 from Member
        where name='11111111'    
　　</select>
</mapper>

这样就基本完成了获取用户的功能！

6.junit测试功能

 1 package com.operate.test;
 2 
 3 import org.junit.Before;
 4 import org.junit.Test;
 5 import org.springframework.context.ApplicationContext;
 6 import org.springframework.context.support.ClassPathXmlApplicationContext;
 7 
 8 import com.operate.dto.User;
 9 import com.operate.service.UserService;
10 
11 public class UserTest {
12     private UserService userService;
13      @Before
14     public void before(){                                                                    
15         @SuppressWarnings("resource")
16         ApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"classpath:conf/spring.xml"
17                 ,"classpath:conf/spring-mybatis.xml"});
18         userService = (UserService) context.getBean("userServiceImpl");//注意userServiceImpl 首字母要小写
19     }
20      
21     @Test
22     public void getUser(){
23         User user = userService.getUser();
24         System.out.println(user.getName()+":"+user.getPhoto());
25     }
26 }

测试结果：

7.SpringMVC搭建
