詳解spring+springmvc+mybatis整合注解
每天記錄一點(diǎn)點(diǎn),慢慢的成長(zhǎng),今天我們學(xué)習(xí)了ssm,這是我自己總結(jié)的筆記,大神勿噴!謝謝,主要代碼??! !
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>
3.創(chuàng)建實(shí)體類
4.引入一個(gè)(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(chuàng)建一個(gè)(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(nèi)容,db.properties文件中key命名要有一定的特殊規(guī)則 -->

<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"

<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(shù):<input type="text" name="money"/>
<input type="submit"/>
</form>
//message.jsp
${message }
