今天就跟大家聊聊有關如何在Spring中使用SpringMVC與Mybatis框架,可能很多人都不太了解,為了讓大家更加了解,小編給大家總結了以下內容,希望大家根據這篇文章可以有所收獲。
基本目錄結構
├── src # │ ├── main # │ │ └── java # java代碼目錄 │ │ └── resources # 配置文件目錄, 存放下面Spring配置文件 │ ├── test # 單元測試目錄 ├── web # web目錄 │ └── WEB-INF # web.xml 配置文件目錄
1、在 resources
目錄下新建數據庫配置文件 database.properties
jdbc.driver=com.mysql.jdbc.Driver # 如果是使用 MySQL8.0+ 那么還需要增加一個時區的配置; serverTimezone=Asia/Shanghai jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8 jdbc.username=root jdbc.password=123456
2、在 resources
目錄下創建Mybatis配置文件 mybatis-config.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> <!--配置數據源, 交給Spring--> <!--配置log--> <settings> <!--STDOUT_LOGGING: 標準的日志工廠實現--> <setting name="logImpl" value="STDOUT_LOGGING"/> </settings> <!--配置別名--> <typeAliases> <package name="com.pro.pojo"/> </typeAliases> <!--綁定Mapper--> <mappers> <mapper class="com.pro.dao.BooksMapper"/> </mappers> </configuration>
1. Spring整合Mybatis
配置Spring整合MyBatis,這里數據源使用c3p0連接池;
編寫Spring整合Mybatis的相關的配置文件;在 resources
目錄下創建 spring-dao.xml
注意:這里要引入上面Mybatis層的兩個配置文件,配置文件的名稱不要寫錯
<?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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!--1. 關聯數據庫配置文件--> <context:property-placeholder location="classpath:database.properties"/> <!--2. 連接池 dbcp: 半自動化操作, 不能自動連接 c3p0: 自動化操作 (自動加載配置文件并設置到對象中) druid, hikari --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="${jdbc.driver}"/> <property name="jdbcUrl" value="${jdbc.url}"/> <property name="user" value="${jdbc.username}"/> <property name="password" value="${jdbc.password}"/> <!--c3p0連接池的私有屬性, 最大最小連接池大小--> <property name="maxPoolSize" value="30"/> <property name="minPoolSize" value="10"/> <!--關閉連接后不自動commit--> <property name="autoCommitOnClose" value="false"/> <!--連接超時--> <property name="checkoutTimeout" value="10000"/> <!--獲取連接失敗重試次數--> <property name="acquireRetryAttempts" value="2"/> </bean> <!--3. sqlSessionFactory--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <!--綁定Mybatis配置文件--> <property name="configLocation" value="classpath:mybatis-config.xml"/> </bean> <!--4. 配置Dao掃描包, 動態實現Dao接口注入到Spring容器中--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!--注入 sqlSessionFactory--> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/> <!--配置要掃描的dao包--> <property name="basePackage" value="com.pro.dao"/> </bean> </beans>
2. Spring整合service
將業務層的類注入到Spring中,在 resources
目錄下創建 spring-service.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" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!--1. 掃描service下的包--> <context:component-scan base-package="com.pro.service"/> <!--2. 將業務層的類注入到Spring中--> <bean id="BooksServiceImpl" class="com.pro.service.BooksServiceImpl"> <property name="booksMapper" ref="booksMapper"/> </bean> <!--3. 配置聲明式事務--> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!--注入數據源--> <property name="dataSource" ref="dataSource"/> </bean> <!--4. 配置aop實現事務織入--> <!--配置事務通知--> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <!--1. 給那些方法配置事務--> <!--2. 配置事務的傳播特性: propagation--> <tx:attributes> <tx:method name="*" propagation="REQUIRED"/> </tx:attributes> </tx:advice> <!--配置事務切入--> <aop:config> <!--mapper包下的所有類的所有方法--> <aop:pointcut id="txPointCut" expression="execution(* com.pro.dao.*.*(..))"/> <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointCut"/> </aop:config> </beans>
1. 編寫web.xml
修改 WEB-INF
下的 web.xml
文件
這里引入Spring整合的配置文件 applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="https://jakarta.ee/xml/ns/jakartaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="https://jakarta.ee/xml/ns/jakartaee https://jakarta.ee/xml/ns/jakartaee/web-app_5_0.xsd" version="5.0"> <!--DispatchServlet--> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!--加載Spring配置文件--> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </init-param> <!--啟動級別--> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!--亂碼過濾--> <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> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!--Session過期時間--> <session-config> <session-timeout>15</session-timeout> </session-config> </web-app>
2. 編寫spring-mvc.xml
在 resources
目錄下創建 spring-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" 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 https://www.springframework.org/schema/context/spring-context.xsd"> <!--1. 注解驅動--> <mvc:annotation-driven/> <!--2. 靜態資源過濾--> <mvc:default-servlet-handler/> <!--3. 掃描包: controller--> <context:component-scan base-package="com.pro.controller"/> <!--4. 視圖解析器--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/"/> <property name="suffix" value=".jsp"/> </bean> </beans>
在 resources
目錄下創建 applicationContext.xml
這里引入上面三個配置文件 spring-dao.xml
、spring-service.xml
、spring-mvc.xml
整合成一個總的配置文件
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <import resource="classpath:spring-dao.xml"/> <import resource="classpath:spring-service.xml"/> <import resource="classpath:spring-mvc.xml"/> </beans>
