每天记录一点点，慢慢的成长，今天我们学习了ssm，这是我自己总结的笔记，大神勿喷！谢谢，主要代码！！ !
spring&springmvc&mybatis整合（注解）
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>
</div>
3.创建实体类
4.引入一个（类名）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>
</div>
5.创建一个（类名）dao
public void update(Accounting a); public Accounting findMoneyByName(String name);</div>
6.写service
public void remit(String from,String to,double money);</div>
7.写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);
}
}
</div>
8.引入applicationContext.xml

<!-- 加载db.properties文件中的内容，db.properties文件中key命名要有一定的特殊规则 -->
<context:property-placeholder location="classpath:db.properties" />
<!-- 配置数据源 ，dbcp -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">

</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扫描器 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 扫描包路径，如果需要扫描多个包，中间使用半角逗号隔开 -->
<property name="basePackage" value="dao"></property>
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
</bean>
</beans>
</div>
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"

<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>
</div>
11.jsp页面编写
//index.jsp:
<form action="account_execute.action" method="post">
汇款人：<input type="text" name="from"/>
收款人：<input type="text" name="to"/>
钱数：<input type="text" name="money"/>
<input type="submit"/>
</form>
//message.jsp
${message }
</div>
