Spring（十二）Spring整合Mybatis

首先第一步引依赖：

<!--Mybatis+Spring整合--><dependency>  <groupId>org.mybatis</groupId>  <artifactId>mybatis-spring</artifactId>  <version>1.2.1</version></dependency><!-- Spring整合JavaWeb的包 --><dependency>  <groupId>org.springframework</groupId>  <artifactId>spring-web</artifactId>  <version>4.2.0.RELEASE</version></dependency><!--mybatis jar包--><dependency>  <groupId>org.mybatis</groupId>  <artifactId>mybatis</artifactId>  <version>3.2.2</version></dependency><!--jstl表达式--><dependency>  <groupId>jstl</groupId>  <artifactId>jstl</artifactId>  <version>1.2</version></dependency>

<!-- Spring整合JavaWeb的包 --><dependency>  <groupId>org.springframework</groupId>  <artifactId>spring-web</artifactId>  <version>4.2.0.RELEASE</version></dependency><dependency>  <groupId>org.springframework</groupId>  <artifactId>spring-context</artifactId>  <version>4.2.0.RELEASE</version></dependency>

2.创建数据库：做一个简单的添加吧：

还得创建两个jsp

3.写dao,service,entity,servlet

　　　　实现类

　　dao层　　

service：

然后就是servlet

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {            request.setCharacterEncoding("utf-8");            String name = request.getParameter("bookname");            String author = request.getParameter("bookauthor");            String bookprice = request.getParameter("bookprice");            Integer price = Integer.parseInt(bookprice);

Book book = new Book();    book.setBookname(name);    book.setBookauthor(author);    book.setBookprice(price);

//ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext18ssm.xml");    ApplicationContext context = WebApplicationContextUtils.getRequiredWebApplicationContext(this.getServletContext());    IBookService service= (IBookService)context.getBean("bookservice");    try {       int count= service.addBook(book);       if (count>0){           request.getRequestDispatcher("/index.jsp").forward(request,response);       }else {           response.sendRedirect("/addBook.jsp");       }    } catch (Exception e) {        e.printStackTrace();    }

}

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {    doPost(request,response);}

最后配置文件

<?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:tx="http://www.springframework.org/schema/tx"       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/tx        http://www.springframework.org/schema/tx/spring-tx.xsd         ">

<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">        <property name="driverClassName" value="${jdbc.driver}"></property>        <property name="url" value="${jdbc.url}"></property>        <property name="username" value="${jdbc.username}"></property>        <property name="password" value="${jdbc.password}"></property>    </bean>

<!--2.识别到jdbc.properties文件-->    <context:property-placeholder location="classpath:jdbc.properties"></context:property-placeholder>

<bean class="org.mybatis.spring.SqlSessionFactoryBean">        <property name="dataSource" ref="dataSource"></property>        <property name="configLocation" value="classpath:Mybatis-config.xml"></property>    </bean>

<!--3.dao-->    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">        <property name="basePackage" value="cn.Spring.t22ssm.dao"></property>    </bean>

<!--4.service-->    <bean id="bookservice" class="cn.Spring.t22ssm.service.IBookServiceImpl">        <property name="bookDao" ref="IBookDao"></property>    </bean>

<!--事务：事务管理器-->    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">        <property name="dataSource" ref="dataSource"></property>    </bean>

<tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>

</beans>
