SpringMVC框架搭建並整合MyBatis

開發工具：IntelliJ idea
開發環境：jdk1.8，tomcat7

項目源碼下載鏈接：http://download.csdn.net/download/ws_flying/10042768

最終項目結構圖：

第一步：使用idea創建maven web項目
1、File->New->Project

2、選擇Maven…具體步驟如下圖

3、填寫GroupId與ArtifactId（相信使用過maven的對這兩個參數並不陌生吧），點擊下一步

4、填寫Project name，爲你的項目取一個名字，點擊Finish，等待完成即可

5、創建完成後，項目結構大致是這個樣子

第二步：搭建SpringMVC環境
1、添加SpringMVC環境所需的依賴，具體如下

<?xml version="1.0" encoding="UTF-8"?>

            <version>1.2</version>
        </dependency>

    </dependencies>
</project>

2、修改web.xml文件，內容及具體配置左右如下

<?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>springmvc</display-name>

    <!-- 指定Spring Bean的配置文件所在目錄。默認配置在WEB-INF目錄下 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:/spring/spring-*.xml</param-value>
    </context-param>

    <!-- 啓動web容器時，自動裝配spring的配置信息 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- spring核心 -->
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!-- 自定義servlet.xml配置文件的位置和名稱，默認爲WEB-INF目錄下，名稱爲[<servlet-name>]-servlet.xml，如spring-servlet.xml -->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath*:/spring/spring-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <filter>
        <description>字符編碼過濾器</description>
        <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>
</web-app>

3、在resources目錄下新建config，spring目錄；在config下新建jdbc.properties文件，裏面存放數據庫配置信息，在spring下新建spring-application.xml及spring-servlet.xml文件（配置DispatchServlet時指定的文件），配置文件具體內容如下

jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/springmvc?useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true
jdbc.username=root
jdbc.password=123456

dbcp.maxIdle=2
dbcp.maxActive=8
dbcp.defaultAutoCommit=false
dbcp.timeBetweenEvictionRunsMillis=30000
dbcp.minEvictableIdleTimeMillis=600000

spring-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       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-4.0.xsd">

    <description>Spring-web MVC配置</description>

    <!-- 配置spring視圖解析器，因爲後面我使用的都是ajax模式的請求，所以這裏不配置也不礙事 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/pages/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

spring-application.xml

       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd

        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">

    <description>Spring公共配置文件</description>

    <!-- 對所有類進行掃描，以完成Bean創建和自動依賴注入的功能 -->
    <context:component-scan base-package="com.springmvc"/>

    <!-- 激活@Controller模式 -->
    <mvc:annotation-driven/>

    <aop:aspectj-autoproxy proxy-target-class="true"/>

    <!-- 靜態資源 -->
    <mvc:default-servlet-handler/>

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

    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="${jdbc.driver}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
        <property name="maxActive" value="${dbcp.maxActive}"/>
        <property name="maxIdle" value="${dbcp.maxIdle}"/>
        <property name="defaultAutoCommit" value="${dbcp.defaultAutoCommit}"/>
        <property name="timeBetweenEvictionRunsMillis" value="${dbcp.timeBetweenEvictionRunsMillis}"/>
        <property name="minEvictableIdleTimeMillis" value="${dbcp.minEvictableIdleTimeMillis}"/>
    </bean>

    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="select*" read-only="false"/>
            <tx:method name="find*" read-only="false"/>
            <tx:method name="get*" read-only="false"/>
            <tx:method name="update*" propagation="REQUIRED"/>
            <tx:method name="insert*" propagation="REQUIRED"/>
            <tx:method name="save*" propagation="REQUIRED"/>
            <tx:method name="add*" propagation="REQUIRED"/>
            <tx:method name="del*" propagation="REQUIRED"/>
            <tx:method name="*"/>
        </tx:attributes>
    </tx:advice>

    <aop:config proxy-target-class="true">
        <aop:pointcut id="interceptorPointCuts"
                      expression="execution(* com.springmvc.service.*.*(..))"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="interceptorPointCuts"/>
    </aop:config>

    <!-- 解析上傳文件 -->
    <bean id="multipartResolver"
          class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <property name="defaultEncoding" value="UTF-8"/>
        <!-- 指定所上傳文件的總大小不能超過50M。注意maxUploadSize屬性的限制不是針對單個文件，而是所有文件的容量之和 -->
        <property name="maxUploadSize" value="52428800"/>
    </bean>

    <bean id="multipartFilter"
          class="org.springframework.web.multipart.support.MultipartFilter">
        <property name="multipartResolverBeanName" value="multipartResolver"></property>
    </bean>
</beans>

省略部分創建java package及class的過程，至此，SpringMVC環境搭建完畢。

5、整合MyBatis，修改spring-application.xml文件即可，具體內容如下（所需依賴前面已經一起引入）

    <!-- 此處省略部分 -->

    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="mapperLocations">
            <list>
                <value>classpath:mapper/*.xml</value>
            </list>
        </property>
    </bean>

    <!-- 掃描basePackage下所有以@MyBatisRepository標識的 接口 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <property name="basePackage" value="com.springmvc.dao"/>
        <property name="annotationClass" value="com.springmvc.commons.MyBatisRepository"/>
    </bean>
    <!-- 此處省略部分 -->
</beans>

到此SpringMVC搭建及整合MyBatis已經全部完成，所以具體其他代碼如下，也可直接下載源碼查看

Constant.java

public class Constant {
    public static final int SUCCESS_CODE = 0;
    public static final int ERROR_CODE = 1;
    public static final String PARM_MISSING = "缺少必要參數";
}

JsonResult.java

import java.util.HashMap;

public class JsonResult {

    public static Object success() {
        HashMap<String, Object> map = new HashMap<String, Object>();
        map.put("code", Constant.SUCCESS_CODE);

        return map;
    }

    public static Object success(Object object) {
        HashMap<String, Object> map = new HashMap<String, Object>();
        map.put("code", Constant.SUCCESS_CODE);
        map.put("data", object);

        return map;
    }

    public static Object fail() {
        HashMap<String, Object> map = new HashMap<String, Object>();
        map.put("code", Constant.ERROR_CODE);

        return map;
    }

    public static Object fail(Object object) {
        HashMap<String, Object> map = new HashMap<String, Object>();
        map.put("code", Constant.ERROR_CODE);
        map.put("data", object);

        return map;
    }
}

MyBatisRepository

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

/**

@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;

public class UserController {
    private static List<String> userList = new ArrayList<String>();

    @Resource

    @RequestMapping("/login")
    public Object login(HttpServletRequest req, User user) {
        System.out.println("login:" + user);
        if (!StringUtils.isEmpty(user.getUsername())) {
            userService.insert(user);
        }

        req.getSession().setAttribute("username", user.getUsername());

        return JsonResult.success();
    }

    @RequestMapping("/getList")
    public Object getList(User user) {

        return JsonResult.success(userService.getList(user));
    }
}
