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

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）

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
