案例：人员管理系统

开发技术

• 开发系统: Win10+MySQL8+Spring4+Mybatis3+Tomcat8.5+IDEA
• 开发技术: JSP/Servlet+MySQL+Spring+Mybatis

开发流程

• 首先完成数据库的设计
• 完成控制模块的开发
• 完成部门及员工管理实现
• 完成登录与个人中心实现
• 最后完成日志处理实现

开发要点

Spring与Mabtis的整合

    <!--Spring 整合 Mybatis-->
    <!--数据源-->
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.cj.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3306/sm?useUnicode=true&amp;characterEncoding=UTF-8&amp;useJDBCCompliantTimezoneShift=true&amp;useLegacyDatetimeCode=false&amp;serverTimezone=GMT%2B8"/>
        <property name="username" value="root"/>
        <property name="password" value="1234"/>
    </bean>
    <!--session工厂-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="typeAliasesPackage" value="com.jesse.sm.entity"/>
    </bean>
    <!--持久化对象-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.jesse.sm.dao"/>
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
    </bean>

Spring事务管理

    <!--声明式事务-->
    <!--事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>
    <!--通知-->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="get*" read-only="true"/>
            <tx:method name="find*" read-only="true"/>
            <tx:method name="search*" read-only="true"/>
            <tx:method name="*" propagation="REQUIRED"/>
        </tx:attributes>
    </tx:advice>
    <!--植入-->
    <aop:config>
        <aop:pointcut id="txPointcut" expression="execution(* com.jesse.sm.service.*.*(..))"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut"/>
    </aop:config>

Spring的IoC容器使用

SpringAOP实现日志管理

@Component
@Aspect
public class LogAdvice {
    @Autowired
    private LogService logService;

    @AfterReturning("execution(* com.jesse.sm.controller.*.*(..)) && !execution(* com.jesse.sm.controller.SelfController.*(..)) && !execution(* com.jesse.sm.controller.*.to*(..))")
    public void operationLog(JoinPoint joinPoint){
        Log log = new Log();
        log.setModule(joinPoint.getTarget().getClass().getSimpleName());
        log.setOperation(joinPoint.getSignature().getName());
        HttpServletRequest request = (HttpServletRequest) joinPoint.getArgs()[0];
        HttpSession session = request.getSession();
        Object obj = session.getAttribute("USER");
        Staff staff = (Staff)obj;
        log.setOperator(staff.getAccount());
        log.setResult("成功");
        logService.addOperationLog(log);
    }

    @AfterThrowing(throwing = "e",pointcut = "execution(* com.jesse.sm.controller.*.*(..)) && !execution(* com.jesse.sm.controller.SelfController.*(..))")
    public void systemLog(JoinPoint joinPoint, Throwable e){
        Log log = new Log();
        log.setModule(joinPoint.getTarget().getClass().getSimpleName());
        log.setOperation(joinPoint.getSignature().getName());
        HttpServletRequest request = (HttpServletRequest) joinPoint.getArgs()[0];
        HttpSession session = request.getSession();
        Object obj = session.getAttribute("USER");
        Staff staff = (Staff)obj;
        log.setOperator(staff.getAccount());
        log.setResult(e.getClass().getSimpleName());
        logService.addSystemLog(log);
    }

    @AfterReturning("execution(* com.jesse.sm.controller.SelfController.login(..))")
    public void loginLog(JoinPoint joinPoint){
        log(joinPoint);
    }

    @Before("execution(* com.jesse.sm.controller.SelfController.logout(..))")
    public void logoutLog(JoinPoint joinPoint){
        log(joinPoint);
    }

    private void log(JoinPoint joinPoint){
        Log log = new Log();
        log.setModule(joinPoint.getTarget().getClass().getSimpleName());
        log.setOperation(joinPoint.getSignature().getName());
        HttpServletRequest request = (HttpServletRequest) joinPoint.getArgs()[0];
        HttpSession session = request.getSession();
        Object obj = session.getAttribute("USER");
        if (obj == null){
            log.setOperator(request.getParameter("account"));
            log.setResult("失败");
        } else {
            Staff staff = (Staff) obj;
            log.setOperator(staff.getAccount());
            log.setResult("成功");
        }
        logService.addLoginLog(log);
    }
}
