使用spring如何實現springmvc與mybatis進行整合?針對這個問題,這篇文章詳細介紹了相對應的分析和解答,希望可以幫助更多想解決這個問題的小伙伴找到更簡單易行的方法。
1.jar包
2.引入web.xml文件
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<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:springmvc.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>3.創建實體類
4.引入一個(類名)dao.xml
<update id="update" parameterType="accounting" >
update accounting set money=#{money} where name=#{name}
</update>
<select id="findMoneyByName" parameterType="string" resultType="accounting">
select * from accounting where name=#{name}
</select>5.創建一個(類名)dao
public void update(Accounting a); public Accounting findMoneyByName(String name);
6.寫service
public void remit(String from,String to,double money);
7.寫serviceimpl
@Service
public class AccountServiceImpl implements AccountService {
@Autowired
private AccountDao ad;
@Override
public void remit(String from, String to, double money) {
Accounting fromAccount=ad.findMoneyByName(from);
fromAccount.setMoney(fromAccount.getMoney()-money);
ad.update(fromAccount);
Accounting toAccount=ad.findMoneyByName(to);
toAccount.setMoney(toAccount.getMoney()+money);
ad.update(toAccount);
}
}8.引入applicationContext.xml

<!-- 加載db.properties文件中的內容,db.properties文件中key命名要有一定的特殊規則 -->
<context:property-placeholder location="classpath:db.properties" />
<!-- 配置數據源 ,dbcp -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<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="30" />
<property name="maxIdle" value="5" />
</bean>
<!-- sqlSessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 數據庫連接池 -->
<property name="dataSource" ref="dataSource" />
<!-- 加載mybatis的全局配置文件 -->
<property name="configLocation" value="classpath:sqlMapConfig.xml" />
</bean>

<property name="dataSource" ref="dataSource"/>
</bean>
<tx:advice id="txAdvice" transaction-manager="transactionManager">

<tx:method name="*" propagation="REQUIRED"/>
</tx:attributes>
</tx:advice>
<aop:config>
<aop:advisor advice-ref="txAdvice" pointcut="execution(* service..*.*(..))"/>
</aop:config>
<!-- mapper掃描器 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 掃描包路徑,如果需要掃描多個包,中間使用半角逗號隔開 -->
<property name="basePackage" value="dao"></property>
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
</bean>
</beans>9.引入db.properties文件和log4j.properties文件
10.引入springmvc.xml文件
<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"

http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.2.xsd ">
<mvc:annotation-driven></mvc:annotation-driven>
<context:component-scan base-package="action"></context:component-scan>
<context:component-scan base-package="service"></context:component-scan>
</beans>11.jsp頁面編寫
//index.jsp:
<form action="account_execute.action" method="post">
匯款人:<input type="text" name="from"/>
收款人:<input type="text" name="to"/>
錢數:<input type="text" name="money"/>
<input type="submit"/>
</form>
//message.jsp
