初始SQL语句

ApplicationContext.xml

</beans>

开启注解扫描，排除springMVC

<context:component-scan base-package="cn.imut">
    <!-- 排除MVC-->
    <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

数据源

<bean id="comboPooledDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
    <property name="driverClass" value="com.mysql.jdbc.Driver"/>
    <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/xx?/>
    <property name="user" value="root"/>
    <property name="password" value="xxx"/>
</bean>

sqlSessionFactory

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="comboPooledDataSource"/>
</bean>

扫描包

<bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="cn.imut.dao"/>
</bean>

配置事务管理

<!-- 配置事务管理器-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="comboPooledDataSource"/>
</bean>
<!-- 事务通知-->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
    <tx:attributes>
        <tx:method name="find*" read-only="true"/>
        <tx:method name="*" isolation="DEFAULT"/>
    </tx:attributes>
</tx:advice>
<!-- 配置AOP-->
<aop:config>
    <aop:advisor advice-ref="txAdvice" pointcut="execution(* cn.imut.service.impl.*ServiceImpl.*(..))"/>
</aop:config>

Web.xml

1.前端控制器

<!-- 前端(视图)控制器-->
<servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- 加载springmvc.xml-->
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:</param-value>
    </init-param>
    <!-- 启动服务器，创建servlet-->
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

2.springMVC自带过滤器

<!-- springMVC自带过滤器-->
    <filter>
        <filter-name>encoding</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>encoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

3.导入springmvc.xml

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--设置配置文件的路径-->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
</context-param>

<servlet>
    <servlet-name>dispatcherServlet</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>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

springmvc.xml

1.开启注解扫描，只扫描Controller

<context:component-scan base-package="cn.imut">
    <context:include-filter type="annotation"           expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

2.配置的视图解析器对象

<bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/pages/"/>
    <property name="suffix" value=".jsp"/>
</bean>

3.过滤静态资源

<mvc:default-servlet-handler/>

4.开启SpringMVC注解支持

<mvc:annotation-driven/>

controller:

@Controller
@RequestMapping("account")
public class AccountController {

    @Autowired
    private AccountService accountService;

    @RequestMapping("/findAll")
    public String findAll(Model model) {
        List<Account> list = accountService.findAll();
        model.addAttribute("list",list);
        return "list";
    }

    @RequestMapping("/save")
    public void save(Account account, HttpServletResponse response, HttpServletRequest request) throws IOException {
        accountService.saveAccount(account);
        response.sendRedirect(request.getContextPath() + "/account/findAll");
        return;
    }
}

dao:

@Repository
public interface AccountDao {
    //查询所有
    @Select("select * from account")
    List<Account> findAll();

    //增加
    @Insert("insert into account (`name`,`money`) values (#{name},#{money})")
    void saveAccount(Account account);
}

pojo:

@Data
@NoArgsConstructor
@AllArgsConstructor
public class Account {
    private Integer id;
    private String name;
    private double money;
}

service:

public interface AccountService {
    //查询所有
    List<Account> findAll();

    //增加
    void saveAccount(Account account);
}

@Service("serviceDaoImpl")
public class AccountServiceImpl implements AccountService {

    @Autowired
    private AccountDao accountDao;

    @Override
    public List<Account> findAll() {
        return accountDao.findAll();
    }

    @Override
    public void saveAccount(Account account) {
        accountDao.saveAccount(account);
    }
}

index.jsp:

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <head>
    <title>$Title$</title>
  </head>
  <body>
        <a href="account/findAll">测试查询</a>

        <h3>测试保存</h3>
        <form action="account/save" method="post">
            姓名:<input type="text" name="name"/><br/>
            金额:<input type="text" name="money"/><br/>
            <input type="submit" value="保存"><br/>
        </form>
  </body>
</html>

list.jsp:

<head>
    <title>Title</title>
</head>
<body>
    <h3>查询所有的帐户</h3>

    <c:forEach items="${list}" var="account">
        ${account.name}
    </c:forEach>
