然後是pom.xml文件

</project>
一、applicationContext.xml
主要的整合思路是：
1. 開啓全局註解掃描，但是除去掃描Controller層註解，由Springmvc配置文件進行開啓註解掃描
<context:component-scan base-package="指定包位置">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" />
</context:component-scan>
2. 配置與數據庫相關的配置信息：
2.1 配置數據源
<!--配置數據源-->
<!--加載數據庫信息配置文件-->
<context:property-placeholder location="數據庫配置文件的位置"/>
<bean class="com.mchange.v2.c3p0.ComboPooledDataSource" id="dataSource">
<property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>
<property name="driverClass" value="${jdbc.jdcbDriverClass}"></property>
<property name="user" value="${jdbc.username}"></property>
<property name="password" value="${jdbc.password}"></property>
</bean>
數據庫配置信息文件：
jdbc.jdbcUrl=jdbc:mysql://localhost:3306/test?characterEncoding=utf8
jdbc.jdcbDriverClass=com.mysql.jdbc.Driver
jdbc.username=用戶名
jdbc.password=密碼
3. 將spring和mybatis整合
<!--Spring與mybais整合-->
<bean class="org.mybatis.spring.SqlSessionFactoryBean" id="sqlSessionFactory">
<!--mybatis全局配置文件-->
<property name="configLocation" value="mybatis配置文件的位置"></property>
<!--配置mybatis的數據源-->
<property name="dataSource" ref="dataSource"></property>
<!--指定mybatis的mapper文件位置-->
<property name="mapperLocations" value="mybatis的mapper文件位置"></property>
</bean>
4. 掃描dao接口的mapper
<!--dao接口所在的包名，Spring會自動查找之中的類-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" id="mapperScannerConfigurer">
<property name="basePackage" value="com.pineapple.dao"></property>
<!--注入工廠-->
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
</bean>
5. 事務管理
<!--事務管理-->
<bean class="org.springframework.jdbc.datasource.DataSourceTransactionManager" id="transactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<!--開啓事務註解掃描-->
<tx:annotation-driven />
2. mybatis-config.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD SQL Map Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<typeAliases>
<!--將數據庫dao接口映射到mybatis的mapper配置文件，一般一個Mapper文件對應一個數據庫操作Dao接口-->
<!--掃描dao包下的所有entity接口，並且設置一個別名，默認的別名就是entity的首字母小寫的非限定類名
例如 :TodoMapper的別名是todoMapper，有什麼用呢？
在service層我們會引入entity接口，這些接口中的方法就映射到了對應的mapper文件
代碼示例：
@Autowired
TodoMapper todoMapper;
-->
<package name="com.pineapple.dao"></package>
</typeAliases>
<!--pageHelper分頁插件-->
<plugins>
<plugin interceptor="com.github.pagehelper.PageInterceptor">
<!-- 分頁參數合理化 -->
<property name="reasonable " value="true"/>
</plugin>
</plugins>
</configuration>
3.applicationContext-mvc.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"

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">
<!--SpringMVC的配置文件，包含網站跳轉邏輯的控制，配置 -->
<context:component-scan base-package="com.pineapple.controller" use-default-filters="false">
<!--只掃描控制器 -->
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!--告知Spring，在springmvc啓用註解-->
<mvc:annotation-driven>
<mvc:message-converters register-defaults="true">
<!-- 配置Fastjson支持 -->
<bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html;charset=UTF-8</value>
<value>application/json</value>
</list>
</property>
<property name="features">
<list>
<value>WriteMapNullValue</value>
<value>QuoteFieldNames</value>
</list>
</property>
</bean>
</mvc:message-converters>
</mvc:annotation-driven>
<!--將Springmvc不能處理的請求交給tomcat-->
<mvc:default-servlet-handler/>
<!--釋放靜態資源-->
<mvc:resources mapping="/static/**" location="/WEB-INF/static/" />
<!--配置Spring的視圖解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!--將controller層返回值變成一個可用的url地址-->
<property name="prefix" value="/WEB-INF/jsp/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
</beans>
4.mybatis逆向工程文件
4.1 配置文件
<?xml version="1.0" encoding="UTF-8"?>
