程序

表现层 业务层 持久层

从持久层开始写

总结如何搭建一个项目

1、新建一个Maven项目

2、可能新建之后会有错，右键Deployment
Descriptor: note, 选择Generate
Deployment Descriptor Stub

3、使用maven仓库导包

<dependencies>

      <dependency>

          <groupId>org.springframework</groupId>

          <artifactId>spring-webmvc-portlet</artifactId>

          <version>3.2.8.RELEASE</version>

      </dependency>

      <dependency>

          <groupId>com.fasterxml.jackson.core</groupId>

          <artifactId>jackson-databind</artifactId>

          <version>2.8.5</version>

      </dependency>

     <dependency>

      <groupId>com.fasterxml.jackson.core</groupId>

      <artifactId>jackson-core</artifactId>

      <version>2.8.5</version>

    </dependency>

    <dependency>

      <groupId>com.fasterxml.jackson.core</groupId>

      <artifactId>jackson-annotations</artifactId>

      <version>2.8.5</version>

    </dependency>

    <dependency>

      <groupId>org.springframework</groupId>

      <artifactId>spring-jdbc</artifactId>

      <version>3.2.8.RELEASE</version>

    </dependency>

    <dependency>

      <groupId>org.mybatis</groupId>

      <artifactId>mybatis</artifactId>

      <version>3.4.0</version>

    </dependency>

    <dependency>

      <groupId>org.mybatis</groupId>

      <artifactId>mybatis-spring</artifactId>

      <version>1.3.1</version>

    </dependency>

    <dependency>

      <groupId>mysql</groupId>

      <artifactId>mysql-connector-java</artifactId>

      <version>5.1.38</version>

    </dependency>

    <dependency>

      <groupId>commons-dbcp</groupId>

      <artifactId>commons-dbcp</artifactId>

      <version>1.4</version>

    </dependency>

  </dependencies>

dependencies

3.1、查看一下下载的包

如果maven的包迟迟不下载，就右键项目，选择maven – UpdateProject

4、 为项目指定tomcat运行环境

右键项目 – Properties – Targeted Runtimes

5.在下面server的tomcat服务器中添加项目

6 、在src/main/resources下添加两个文件夹

7 、 Spring配置文件

先将原项目的两个配置文件 spring-service.xml和 spring-mybatis.xml 复制过来

将spring-service.xml 改名为spring-web.xml,因为这样更合适一点

spring-mybatis.xml注意改一下文件里的包名，其他的关于mybatis的不用改

spring-web.xml如下：

<?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:jdbc="http://www.springframework.org/schema/jdbc"

    xsi:schemaLocation="

    <!-- 启动注解版本的Spring MVC -->

    <mvc:annotation-driven></mvc:annotation-driven>

    <context:component-scan base-package="cn.edu.sdu.wh.controller"> </context:component-scan>

</beans>

spring-web.xml

spring-mybatis.xml如下：

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <!-- 声明MyBatis SQL 声明文件保存的地方 -->

        <property name="mapperLocations" value="classpath:mapper/*.xml"></property>

    </bean>

    <!-- 配置MyBatis的自动接口扫描 -->

        <!-- 数据访问接口的存储位置 -->

        <property name="basePackage" value="cn.edu.sdu.wh.dao"></property>

    </bean>

</beans>

spring-mybatis.xml

8 、 相应的在src/main/java下添加两个包

9 、 新建一个Servlet

可以查看src/main/webapp/WEB-INF下的web.xml，验证一下

10 、 将Tomcat 发布 然后 运行！
