1.准备工作:

　　

1.创建数据源
CREATE TABLE `users` (
  `id` int(10) NOT NULL AUTO_INCREMENT,
  `name` varchar(20) DEFAULT NULL,
  `price` float(10,0) DEFAULT NULL,
  `pic` varchar(40) DEFAULT NULL,
  `createtime` datetime DEFAULT NULL,
  `detail` varchar(200) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=27 DEFAULT CHARSET=utf8;

2.工程模块如下:
users-parent        pom    父工程，统一管理子工程和jar包版本
users-model            jar    封装JavaBean对象
users-dao            jar    持久层
users-service        jar    业务层
users-web            war    控制层

 

2.创建父工程 :

　　(1)导入pom.xml

　　

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<modelVersion>4.0.0</modelVersion>

<groupId>com.bky</groupId>
<artifactId>users-parent</artifactId>
<version>1.0-SNAPSHOT</version>

<!--管理的模块--> 模块创建后会自己创建

<module>users-dao</module>
<module>users-service</module>
<module>users-web</module>
</modules>

<!--

　　(2) usersMapper.xml 映射器




<?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="com.bky.mapper.usersMapper">

    <!--根据ID查询-->
    <select id="getById" parameterType="int" resultType="users">
      select * from users where id=#{id}
    </select>
</mapper>




　　(3)创建dao接口


　　




public interface UsersMapper {
    users getById(Integer id);
}




　　(4)创建spring-dao.xml配置文件(忘记写了,只能放后面了)


　　




<?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:p="http://www.springframework.org/schema/p"
       xs    i:schemaLocation="

        http://www.springframework.org/schema/beans/spring-beans.xsd">


    <!-- 数据库连接池 -->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
          destroy-method="close">
        <property name="url" value="jdbc:mysql://127.0.0.1:3306/maven?characterEncoding=utf8" />

    </bean>

    <!-- SqlSessionFactoryBean -->
    <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="typeAliasesPackage" value="com.bky.model" />
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!-- 配置接口扫描包 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"
              p:basePackage="com.bky.mapper"/>
</beans>




　　typeAliasesPackage:指定JavaBean的别名包路径


5.创建users-service


　　(1)导入pom.xml


　　




<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>users-parent</artifactId>
        <groupId>com.bky</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>
    <artifactId>users-service</artifactId>
    <packaging>jar</packaging>


    <!--引入依赖-->
    <dependencies>
        <!--依赖dao-->
        <dependency>
            <groupId>com.bky</groupId>
            <artifactId>users-dao</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>


        <!-- spring -->
        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjweaver</artifactId>
        </dependency>


        <dependency>
            <groupId>org.springframework</groupId>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-tx</artifactId>
        </dependency>
    </dependencies>


</project>




 


　　(2) 创建spring-service.xml


　　




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



    <!--
        1.包扫描
        2.配置声明式事务
            a.准备数据源
            b.配置事务管理器
            c.配置事务执行规则[事务的传播特性]
            d.配置通知，指定切点
    -->


    <!--包扫描-->
    <context:component-scan base-package="com.bky">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" />
    </context:component-scan>


    <!--
        配置声明式事务
        准备数据源
        <import resource="spring-mybatis.xml" />:相当于将spring-mybatis.xml的配置融合过来了
        可以直接使用导入的配置文件的配置信息
    -->
    <import resource="spring-mybatis.xml" />


    <!--配置事务管理器-->
    <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!--注入数据源-->
        <property name="dataSource" ref="dataSource" />
    </bean>


    <!--配置事务执行规则[事务的传播特性]-->
    <tx:advice id="txAdvice" transaction-manager="txManager">
        <tx:attributes>
            <tx:method name="add*" />
            <tx:method name="update*" />
            <tx:method name="delete*" />
            <!--只读-->
            <tx:method name="*" read-only="true" />
        </tx:attributes>
    </tx:advice>


    <!--配置通知，指定切点-->
    <aop:config>
        <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.bky.service.impl.*.*(..))" />
    </aop:config>
</beans>




　此处<import resource="spring-dao.xml" />:表示引入spring-dao.xml配置，相当于将二者配置合并到了一起。


　如果springmvc将这个配置文件引入,那么可以不需要再web.xml中用监听器创建spring容器


 


　　(3)创建service接口


　　




public interface usersService {
    users getById(Integer id);
}




　　(4)创建实现类


　　




@Service
public class usersServiceImpl implements usersService {

    @Autowired
    private usersMapper usersMapper;

    @Override
    public users getById(Integer id) {
        return usersMapper.getById(id);
    }
}




 


6.创建users-web模块


　　(1)导入pom.xml


　　




<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </plugin>
        </plugins>
    </build>
</project>




 


　　(2)web.xml


该工程属于web工程，需要在web.xml中配置SpringMVC前端核心控制器和POST编码过滤器，代码如下：






<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">




 <!--

        配置编码过滤器POST请求
        配置SpringMVC核心配置文件
    -->





    <!--SpringMVC:配置核心前端控制器-->
    <servlet>
        <servlet-name>dispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>




 <!--指定SpringMVC核心配置文件-->

            <param-value>classpath:springmvc.xml</param-value>
        </init-param>
        <!--启动加载优先级[创建SpringMVCIOC容器]-->
        <load-on-startup>1</load-on-startup>
    </servlet>
    
    <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>





    <!--配置编码过滤器POST请求-->
    <filter>
        <filter-name>characterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>




 <!--指定编码-->
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>





    <!--指定Spring配置文件-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring.xml</param-value>

 <!--监听器，创建SpringIOC容器-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
</web-app>


 




 


　　(3)创建springmvc.xml

　　(4)创建Controller接口(web层接口)




@Controller
@RequestMapping(value = "/users")
public class usersController {

    @Autowired
    private usersService usersService;

    /***
     * 根据ID查询
     * @param id
     * @param model
     * @return
     */
    @RequestMapping(value = "/one")
    public String getById(Integer id, Model model){
        users users = usersService.getById(id);
        model.addAttribute("users",users);
        return "users";
    }
}
