引入jdbc配置：

<!--引入jdbc配置-->
<context:property-placeholder location="classpath:config.properties"/>

数据源：

        </array> 
    </property> 
</bean>

mybatis-config.xml：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

    <!--设置别名-->
    <typeAliases>
        <package name ="com.mlq.ben" />
    </typeAliases>

</configuration>

装配Mapper接口：

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="com.mlq.mapper"></property>
</bean>

扫描全局注解：

<context:component-scan base-package=""/>

静态资源访问及View试图：

<!--配置静态资源-->
<mvc:resources mapping="/static/**" location="/static/"/>
<!--注解解析器适用于试图解析-->
<mvc:annotation-driven/>
<!--配置试图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/Jsp/"/>
    <property name="suffix" value=".jsp"/>
</bean>

　　<property name="dataSource" ref="dataSource"></property>
</bean>
<!--添加扫描事务注解-->
<tx:annotation-driven transaction-manager="txManager"/>

使用：
@Transactional(propagation = Propagation.REQUIRED)

XML事务配置：

<!--创建事务管理器-->
    <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="datasource"/>
    </bean>
    <!--实务增强通知-->
    <tx:advice id="txAdvice" transaction-manager="txManager">
        <tx:attributes>

            <tx:method name="*" isolation="DEFAULT" propagation="REQUIRED"></tx:method>
        </tx:attributes>
    </tx:advice>
    <!--定义切面-->
    <aop:config>
        <!--定义切入点-->
        <aop:pointcut id="mypory" expression="execution(* *.service..*.*(..))"></aop:pointcut>
        <!--定义顾问-->
        <aop:advisor advice-ref="txAdvice" pointcut-ref="mypory"/>
    </aop:config>

注解配置增强核心配置：

注解类：

@Aspect
public class MyAspectj {
    //前置增强
    @Before("execution(* *..service..*.eat())")
    public void before()
    {
        System.out.println("===========前置=============");
    }
}

注解Spring-Aspectj.xml：配置：

<!--增强类-->
<bean id="myAspectj" class="mlq.uitl.MyAspectj"/>
<!--Aspectj 自动扫描匹配-->
<aop:aspectj-autoproxy/>

XML配置增强核心配置：

实体类：

/**
 * @author asus
 */
public class MyAspectj1 {
    //前置增强
    public void before()
    {
        System.out.println("
===========前置=============");
    }
    //后置增强
    public void after()
    {
        System.out.println("
===========后置=============");
    }
    //异常增强
    public void abnormal(RuntimeException e)
    {
        System.out.println("
===========异常=============");
    }
    //环绕增强
    public void surround(ProceedingJoinPoint joinpoint)
    {
        System.out.println("
===========环绕前=============");
        try {
            joinpoint.proceed();
        } catch (Throwable throwable) {
            throwable.printStackTrace();
        }
        System.out.println("
===========环绕后=============");
    }
    //最终增强
    public void finalAfter()
    {
        System.out.println("
===========最终=============");
    }
}
