（1）MyBatis Spring整合配置對映介面類與對映xml檔案：http://blog.csdn.net/qq_28919279/article/details/74738886
（2）ssm框架學習(一)------ssm框架整合實現登入功能：http://www.cnblogs.com/codeRose/p/6617578.html
（3）spring與mybatis三種整合方法：https://www.cnblogs.com/wangmingshun/p/5674633.html
（4）springframeworkjar包下載地址：http://repo.spring.io/libs-release-local/org/springframework/spring/
一、準備所需的jar包
1.1所需jar包(下載)
1.Spring框架jar包
2.Mybatis框架jar包
4.資料庫驅動jar包
5.資料來源c3p0所需jar包
6.其他的包（aspectj框架jar包、aop聯盟jar包、JSTL標籤庫jar包）需要的時候才加進去
7.對於MyBatis還有一個自動生成XML配置對映檔案的工具，如下：
mybatis-generator-core-1.3.2-bundle.zip
二、準備資料庫資源
2.1使用MySQL建立資料庫和表
set names gbk;//告知mysql伺服器端當前插入的資料採用 GBK 編碼 CREATE SCHEMA hr; USE hr; CREATE TABLE user_inf( id INT(11) UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY, loginName VARCHAR(20) NOT NULL, password VARCHAR(16) NOT NULL, status INT(11) UNSIGNED NOT NULL DEFAULT '1', createDate TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP, userName VARCHAR(20) DEFAULT NULL )ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8; INSERT INTO user_inf (id,loginName,password,status,createDate,userName) VALUES (1,"admin","123456",2,"2018-01-08 17:01:50","超級管理員");
三、完成配置檔案
3.1編寫db.properties檔案
dataSource.driverClass=com.mysql.jdbc.Driver dataSource.jdbcUrl=jdbc:mysql://localhost:3306/hr?useUnicode=true&&characterEncoding=UTF8 dataSource.user=root dataSource.password=123456 dataSource.maxPoolSize=20 dataSource.minPoolSize=6 dataSource.maxIdleTime=1000 dataSource.initialPoolSize=5
3.2編寫mybatis-config.xml檔案
- MyBatis中typealiases的使用：http://blog.csdn.net/lelewenzibin/article/details/42713585
<?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>
<!-- 通過package, 可以直接指定package的名字， mybatis會自動掃描你指定包下面的javabean, 並且預設設定一個別名，預設的名字為：
javabean 的首字母小寫的非限定類名來作為它的別名。 也可在javabean 加上註解@Alias 來自定義別名， 例如： @Alias(user)
<package name="com.dy.entity"/> -->
<typeAlias type="com.pojo.User" alias="User" />
</typeAliases>
</configuration>3.3編寫applicationContext.xml檔案
- MyBatis集合Spring（三）之mapper：http://blog.csdn.net/owen_william/article/details/51815567
<?xml version="1.0" encoding="UTF-8"?>

<!-- 配置dbcp資料來源 -->
<bean id ="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"/>
<!-- 使用PropertyOverrideConfigurer後處理器載入資料來源引數 -->
<context:property-override location="classpath:db.properties"/>
<!-- org.mybatis.spring.SqlSessionFactoryBean是Mybatis社群開發的用於整合spring的bean -->
<!-- 配置mybatisSqlSessionFactoryBean -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="classpath:mybatis-config.xml"/>
<property name="mapperLocations" value="classpath:com/dao/*Mapper.xml"/>
</bean>
<!-- mybatis:scan會將com.mapper包裡的所有介面當作mapper配置，之後可以自動引入mapper類，即不需要手動引入mapper類 -->
<!-- 配置mybatis mapper介面 -->
<mybatis:scan base-package="com.dao" factory-ref="sqlSessionFactory"/>
<!-- 掃描org.orm.pojo下的java元件，有spring相關注解的類，則把這些類註冊為spring的bean -->
<context:component-scan base-package="com"/>
<!-- jdbc事務管理器 ,將資料來源引用到jdbc事務管理器-->
<!-- 事務配置 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager" p:dataSource-ref="dataSource"/>
<!-- 啟動@Transactional註解-->
<tx:annotation-driven transaction-manager="transactionManager"/>
</beans>3.4編寫springmvc-config 配置檔案
<?xml version="1.0" encoding="UTF-8"?>
<!-- <beans>中要加入“xmlns：mvc”的命名申明，即mvc這個名字是可以隨便改的，並在“xsi：schemaLocation”中指定mvc配置的schema的地址 -->
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
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-4.3.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.3.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd"
>
<!-- 指定需要被自動掃描的包，springmvc會將包下用了@controller註解的類註冊為spring的controller -->
<context:component-scan base-package="com.controller"></context:component-scan>
<!-- 設定預設配置方案 -->
<mvc:annotation-driven/>
<!-- 使用預設的Servlet來響應靜態檔案 -->
<mvc:default-servlet-handler/>
<!-- 檢視解析器 -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 字首 -->
<property name="prefix">
<value>/view/</value>
</property>
<!-- 字尾 -->
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
</beans>3.5編寫web.xml檔案
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID" version="3.0">
<display-name>HRManager</display-name>
<!--定位呼叫spring配置檔案（用上下文引數contextConfigLocation引數來定位spring配置檔案的位置），以定義web的初始化上下文環境-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- 呼叫spring的核心監聽器ContextLoaderListener，以定義web的上下文監聽器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 呼叫springmvc的DispatcherServlet類，以定義web的servlet控制器 -->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 定位呼叫springmvc的配置檔案 ，以初始化Servlet控制器-->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc-config.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- 讓Spring MVC的前端控制器攔截所有請求 -->
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!-- 攔截器只能對action請求起作用，而過濾器則可以對幾乎所有的請求起作用-->
<!-- 呼叫spring的編碼過濾器類，以定義web的過濾器 -->
<filter>
<filter-name>characterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

</init-param>
</filter>
<filter-mapping>
<filter-name>characterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<welcome-file-list>
<welcome-file>view/login.jsp</welcome-file>
</welcome-file-list>
</web-app>四、MVC模組解析
五、持久層功能實現
User.java
public class User implements Serializable{
private Integer id; //id
private String loginName; //登入名
private String password; //密碼
private Integer status; //狀態
private Date createDate; //建檔日期
private String userName; //使用者名稱
set...get...
}UserMapper.java
public interface UserMapper {
public User select(int id);
public List<User> selectAll();
public void insert(User user);
public void delete(int id);
public void update(User user);
public User selectByLoginNameAndPassword(String loginName,String password);
}UserMapper.xml
1. MyBatis傳多個引數的3種方法：http://blog.csdn.net/qq_28174471/article/details/52585130
2.
<?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.dao.UserMapper">
<select id="select" parameterType="int" resultType="User">
select * from user_inf where id = #{id}
</select>
<select id="selectByLoginNameAndPassword" resultType="User">
select * from user_inf where loginName = #{arg0} and password = #{arg1}
</select>
<select id="selectAll" resultType="User">
select * from user_inf
</select>
<insert id="insert" parameterType="User"
useGeneratedKeys="true">
insert into user_inf (loginName,password,status,userName) values (#{loginName},#{password},#{status},#{userName})
</insert>
<delete id="delete" parameterType="int">
delete from user_inf where id=#{id}
</delete>
<update id="update" parameterType="User">
update user_inf set loginName=#{loginName},password=#{password},status=#{status},userName=#{userName} where id=#{id}
</update>
</mapper>六、服務層功能實現
UserService.java
public interface UserService {
/**
* 判斷使用者登入
* @param String loginname
* @param String password
* @return 找到返回User物件，沒有找到返回null
* */
public User login(String loginName,String password);
}
UserServiceImpl.java
@Service("userService")
public class UserServiceImpl implements UserService{
/*2016年時候，Service層注入mybatis介面mapper的時候需要在構造方法中注入，
* 這樣注入mapper例項才不會空
* */
@Autowired
private UserMapper userMapper;
@Override
public User login(String loginName, String password) {
return userMapper.selectByLoginNameAndPassword(loginName,password);
}
}七、控制層功能實現
userController.java
@Controller
public class userController {
@Autowired
@Qualifier("userService")
private UserService userService;
/**
* 處理/login請求,ModelAndView和HttpSession以物件入參的方式，實現依賴注入，且不用初始化
*/
@RequestMapping(value="/user/login",method=RequestMethod.POST)
public ModelAndView login(String loginName,String password,ModelAndView mv,HttpSession session) {
try {
User user = userService.login(loginName, password);
System.out.println("請求：" + loginName+"/n查詢結果：" + user.getUserName());
System.out.println("查詢結果：" + user.getUserName());
// 登入成功，將user物件設定到HttpSession作用範圍域中
session.setAttribute("user", user);
// 重定向到index請求
mv.setViewName("redirect:/view/index.jsp");
} catch (Exception e) {
// 登入失敗，設定失敗資訊，並調轉到登入頁面
mv.addObject("error", "登入名和密碼錯誤，請重新輸入!");
mv.setViewName("login");
e.printStackTrace();
}
return mv;
}
}八、JSP頁面實現
login.jsp
