SSM

1.导入jar包

      

        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
            <version>3.2.2</version>
        </dependency>

        <!--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>

2.创建实体类

public class Book {
 private String bookauthor;
    private String bookname;
    private Integer bookprice;

    public String getBookauthor() {
        return bookauthor;
    }

    public void setBookauthor(String bookauthor) {
        this.bookauthor = bookauthor;
    }

    public String getBookname() {
        return bookname;
    }

    public void setBookname(String bookname) {
        this.bookname = bookname;
    }

    public Integer getBookprice() {
        return bookprice;
    }

    public void setBookprice(Integer bookprice) {
        this.bookprice = bookprice;
    }
}

　　3.接口和小配置

public interface IBookDAO {
    //添加图书
    public int addBook(Book book);
}

　　

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE mapper
            PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
            "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
    <mapper namespace="dayssm.dao.IBookDAO">
     <!--添加图书-->
    <insert id="addBook">
        insert into book(bookname,bookauthor,bookprice) values(#{bookname},#{bookauthorw},#{bookprice})
    </insert>

    </mapper>

　　4.service层：

public interface IBookService {
    //添加图书
    public int addBook(Book book);
}

　　

public class BookServiceImpl implements IBookService {
    //植入dao
    private IBookDAO bookDAO;
    public int addBook(Book book) {
        return bookDAO.addBook(book);
    }

    public IBookDAO getBookDAO() {
        return bookDAO;
    }

    public void setBookDAO(IBookDAO bookDAO) {
        this.bookDAO = bookDAO;
    }
}

　　5.servlet层

public class BookServlet extends HttpServlet {
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        request.setCharacterEncoding("utf-8");
        String bookname=request.getParameter("bookname");
        String bookauthor=request.getParameter("bookauthor");
        int bookprice=Integer.parseInt(request.getParameter("bookprice"));

        Book book=new Book();
        book.setBookname(bookname);
        book.setBookprice(bookprice);
        book.setBookauthor(bookauthor);
       //ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext23ssm.xml");
        ApplicationContext ac = WebApplicationContextUtils.getRequiredWebApplicationContext(this.getServletContext());
        IBookService service=(IBookService) ac.getBean("service");
        int i=service.addBook(book);
        if (i>0){
            request.getRequestDispatcher("/index.jsp").forward(request,response);
        }else{
            request.getRequestDispatcher("/add.jsp").forward(request,response);
        }
    }

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

　　6.配置

  <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
        <property name="url" value="jdbc:mysql://localhost:3306/smbms"></property>
        <property name="username" value="root"></property>
        <property name="password" value=""></property>
    </bean>

    <!--2.识别到jdbc.properties文件-->
    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="location" value="classpath:jdbc.properties"></property>
    </bean>

    <!--关键点：SqlSessionFactory生成权交给Spring-->
    <bean class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <!--大配置-->
        <property name="configLocation" value="classpath:MyBatis-Config.xml"></property>
        <!--<property name="mapperLocations" value="classpath:mapper/*.xml"></property>-->
    </bean>

    <!--3.bookDAO    没有实现类-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="dayssm.dao"></property>
    </bean>


    <!--5.service id-->
    <bean id="service" class="dayssm.service.BookServiceImpl">
        <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>

    <!--方式三：AspectJ AOP 注解-->
    <tx:advice id="stockAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="buy*" isolation="DEFAULT" propagation="REQUIRED" rollback-for="StockException"/>
            <tx:method name="select*" isolation="DEFAULT" propagation="REQUIRED" read-only="true"/>
        </tx:attributes>
    </tx:advice>

    <aop:config>
        <!--1.切点-->
        <aop:pointcut id="mypointcut" expression="execution(* *..service.*.*(..))"></aop:pointcut>
        <!--3.顾问-->
        <aop:advisor advice-ref="stockAdvice" pointcut-ref="mypointcut"></aop:advisor>
        <!--2.切面-->


    </aop:config>
