建立好maven項目後，開始搭建框架。html

項目結構以下：前端

resource文件夾下建立了三個文件夾mybatis，spring，它們分別用來放相關的配置文件，mapper 文件夾則是用來放查詢數據庫的xml文件。generatorConfjg.xml是用於代碼生成的，在這裏能夠去掉，且不作講述。taglib.xml文件也能夠去掉，與本文無關。java

1.引入包mysql

在pom.xml文件中添加相關依賴包。我這裏引入了一些代理包，能夠自行去掉。web

            <version>2.4</version>
        </dependency>
    </dependencies>
    <!--file end-->

2.修改web.xml文件redis

    <!-- 加載spring容器-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:config/spring/springContext.xml</param-value>
    </context-param>

    <!-- 配置Spring字符編碼過濾器 -->
    <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- 配置監聽器-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>


    <!-- 配置前端控制器-->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:config/spring-mvc.xml</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

3.修改springmvc.xml文件spring

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

    <context:component-scan base-package="cn.youye.mvc.controller"/>
    <context:component-scan base-package="cn.youye.mvc.service"/>

    <mvc:annotation-driven></mvc:annotation-driven>

    <!--視圖解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/"/>
        <property name="suffix" value=".jsp"/>
    </bean>


</beans>

4.添加數據庫配置文件db.propertiessql

注：我所使用的數據庫是testuser，須要根據本身的狀況修改數據庫以及用戶名和鏈接密碼。數據庫

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/testuser?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=123456
#pool settings
jdbc.initialSize=1
jdbc.minIdle=3
jdbc.maxActive=20

5.添加日誌文件配置文件log4j.propertiesexpress

#console log
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} [%t] %-5p %c - %m%n


#logger
#log4j.logger.org.springframework=DEBUG,CONSOLE
#log4j.logger.org.hibernate=INFO,CONSOLE
#log4j.logger.org.apache=INFO,CONSOLE

log4j.rootLogger=DEBUG,CONSOLE

6.修改springConfig-dao.xml文件

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

       http://www.springframework.org/schema/aop

    <context:component-scan base-package="cn.youye.mvc"/>

    <context:property-placeholder location="classpath:/db.properties"/>

    <!-- 配置數據源 使用的是alibaba的數據源 也可使用 dbcp-->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
          init-method="init" destroy-method="close">

        <property name="maxActive" value="${jdbc.maxActive}"/>
        <property name="minIdle" value="${jdbc.minIdle}"/>
    </bean>

    <!-- 配置SqlSessionFactory mybatis文件配置 掃描全部的mapper文件-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 數據源-->
        <property name="dataSource" ref="dataSource"/>

        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
    </bean>


    <!-- 定義事務管理器 對mybatis操做數據庫的控制，spring使用jdbc的事務控制-->
    <bean id="transactionManager"

    <aop:aspectj-autoproxy proxy-target-class="true"/>
    <!-- 啓用對事物的註解支持-->
    <tx:annotation-driven transaction-manager="transactionManager"/>
</beans>

7.修改mybatisConfig.xml

<?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>
        <package name="cn.youye.mvc.entity"/>
    </typeAliases>
</configuration>

就此環境搭建完成

測試以下：

1.user.class

package cn.youye.mvc.entity;


/**
 * Created by pc on 2016/7/12.
 */
public class User {

    private String id;

    private String name;

    private String password;

    private String icon;

    public User(String id, String name, String password, String icon) {
        this.id = id;
        this.name = name;
        this.password = password;
        this.icon = icon;
    }

    public User() {
        super();
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getIcon() {
        return icon;
    }

    public void setIcon(String icon) {
        this.icon = icon;
    }
}

2.userDao.java

@Repository("userDao")
public interface UserDao {

    User get(User user);
}

3.userService.java

@Service
public class UserService {

    @Autowired
    UserDao userDao;

    public User get(User user) {
        user.setId("b41f12fd-4807-11e6-ba31-408d5cc10d3b");
        return userDao.get(user);
    }
}

4.userController.java

@Controller
public class UserController {

    @Autowired
    UserService userService;

    @RequestMapping(value = "/login")
    public String login(@RequestParam String name, @RequestParam String password, HttpServletRequest request) {

        try {
            User user = new User();
            user.setName(name);
            user.setPassword(password);
            user = userService.get(user);
            if (user != null) {
                request.setAttribute("msg", "登錄成功");
                return "modules/sys/success";
            } else {
                request.setAttribute("msg", "登陸失敗");
                return "modules/sys/login";
            }
        } catch (Exception e) {
