SSM整合

1 创建数据库

create database ssmbuild;

use ssmbuild;

create table books(
    bookID int(10) KEY not null auto_increment comment ‘书id‘,
    bookName varchar(100) not null comment ‘书名‘,
    bookCounts int(11) not null comment ‘数量‘,
    detail varchar(200) not null  comment ‘描述‘
)engine = INNODB default charset=utf8;

INSERT INTO books(BOOKID, BOOKNAME, BOOKCOUNTS, DETAIL) VALUES
(1,‘JAVA‘,1,‘从入门到放弃‘),(2,‘Mysql‘,10,‘从删库到跑路‘),(3,‘Linux‘,5,‘从入门到放弃‘);

7 spring-service.xml spring与service层的整合

<!--    扫描service下的包-->

<!--    2.将所有的业务类，注入到spring，可以通过配置或注解实现-->
    <bean id="BookServiceImpl" class="com.mjoe.service.BookServiceImpl">
        <property name="bookMapper" ref="bookMapper"/>
    </bean>

<!--    3. 声明式事务配置-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

        <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointCut"/>
    </aop:config>
</beans>

8 springmvc.xml 配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"

       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc  http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!--    注解驱动-->
    <mvc:annotation-driven/>

<!--    静态资源过滤-->
    <mvc:default-servlet-handler/>

<!--    扫描controller包-->
    <context:component-scan base-package="com.mjoe.controller"/>

<!--    视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
    
</beans>

9 applicationContext.xml 总spring配置导入

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
    
    <import resource="spring-dao.xml"/>
    <import resource="spring-service.xml"/>
    <import resource="spring-mvc.xml"/>
</beans>

此时，所有的配置已经使得spring接管了dao包、service包所有的接口和实现类，并完成了注入，只需要在Controller中直接调用bean名即可使用其中的方法。
