  • MyBatis学习(二):与Spring整合(非注解方式配置MyBatis)

    搭建SpringMVC的-->传送门<--

    一、环境搭建:

    目录结构:

    引用的JAR包:

    如果是Maven搭建的话,pom.xml的配置如下:

    <?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">
      <modelVersion>4.0.0</modelVersion>
    
      <groupId>org.yoki.edu</groupId>
      <artifactId>MyBatisSpringTest</artifactId>
      <version>1.0-SNAPSHOT</version>
      <packaging>war</packaging>
    
      <properties>
        <version.springframework.boot>1.4.1.RELEASE</version.springframework.boot>
        <version.springframework>4.3.3.RELEASE</version.springframework>

        <version.datasource.durid>1.0.26</version.datasource.durid>
      </properties>

      </dependencies>
      <build>
        <finalName>MyBatisSpringTest</finalName>
      </build>
    
    </project>

    二、数据库的搭建:

    /*如果已经存在此数据库,先删除*/
    drop database if exists apptest;
    /*创建并设置编码为UTF-8*/
    create database apptestdefault character set utf8 ;
    /*选择数据库*/
    use apptest;
    
    /*==============================================================*/
    /* Table: uc_customer               会员表                               */
    /*==============================================================*/
    DROP TABLE IF EXISTS uc_customer;
    CREATE TABLE uc_customer(
        fd_id                 INT     AUTO_INCREMENT    NOT NULL    COMMENT'主键id',
        fd_idCode             VARCHAR(64)             COMMENT'用户编号',
        fd_userName           VARCHAR(50)             COMMENT'登录名',
        fd_pswd               VARCHAR(128)            COMMENT'密码',
        fd_cellphone          VARCHAR(20)             COMMENT'手机号',
        fd_email              VARCHAR(30)             COMMENT'邮箱',
        PRIMARY KEY(fd_id)
    )ENGINE=INNODB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 COMMENT'会员表';
    INSERT INTO `apptest`.`uc_customer`
    (`fd_idCode`,`fd_userName`,`fd_pswd`,`fd_cellphone`,`fd_email`)
    VALUES
    ('101', 'ZhangSan', '***101', '07978210768', '101@yoki.com');
    
    INSERT INTO `apptest`.`uc_customer`
    (`fd_idCode`,`fd_userName`,`fd_pswd`,`fd_cellphone`,`fd_email`)
    VALUES
    ('102', 'LiSi', '***102', '07978210102', '102@yoki.com');

    三、配置文件的编写:

    web.xml:

    <!DOCTYPE web-app PUBLIC
            "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
            "http://java.sun.com/dtd/web-app_2_3.dtd" >
    
    <web-app>
        <!--配置首页-->
        <welcome-file-list>
            <welcome-file>index.jsp</welcome-file>
        </welcome-file-list>
    
        <!--配置springmvc DispatcherServlet-->
        <servlet>
            <servlet-name>springMVC</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            <init-param>
                <!--指定SpringMVC的配置文件,如果不配置这一项默认为"[servlet-name]-servlet.xml"-->
                <param-name>contextConfigLocation</param-name>
                <param-value>classpath:spring-mvc.xml</param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>
        </servlet>
        <servlet-mapping>
            <servlet-name>springMVC</servlet-name>
            <url-pattern>/</url-pattern>
        </servlet-mapping>
    
        <!--Spring监听器的配置-->
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>
        <!--指定Spring配置文件-->
        <context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:ApplicationContext.xml</param-value>
        </context-param>
    
    </web-app>

    jdbc.properties文件的配置:

    jdbc.driver=com.mysql.jdbc.Driver
    jdbc.url=jdbc:mysql://localhost:3306/AppTest?useUnicode=true&characterEncoding=utf-8
    jdbc.username=root
    jdbc.password=root
    
    druid.max-wait=6000
    druid.max-active=2000
    druid.min-idle=1
    druid.initial-size=1

    spring-mvc.xml文件的配置:

    <?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"

                            http://www.springframework.org/schema/mvc
                            http://www.springframework.org/schema/mvc/spring-mvc.xsd">
        <!--启用spring的一些annotation -->
        <context:annotation-config/>
    
        <!-- 配置注解驱动 可以将request参数与绑定到controller参数上 -->
        <mvc:annotation-driven/>
    
        <!-- 自动扫描该包,使SpringMVC认为包下用了@controller注解的类是控制器 -->
        <context:component-scan base-package="org.yoki.edu">
            <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
        </context:component-scan>
    
        <!--HandlerMapping 无需配置,springmvc可以默认启动-->
    
        <!--静态资源映射-->
        <!--本项目把静态资源放在了WEB-INF的statics目录下,资源映射如下-->
        <!--<mvc:resources mapping="/css/**" location="/WEB-INF/statics/css/"/>-->
        <!--<mvc:resources mapping="/js/**" location="/WEB-INF/statics/js/"/>-->
        <!--<mvc:resources mapping="/image/**" location="/WEB-INF/statics/image/"/>-->
    
        <!--但是项目部署到linux下发现WEB-INF的静态资源会出现无法解析的情况,但是本地tomcat访问正常,因此建议还是直接把静态资源放在webapp的statics下,映射配置如下-->
        <mvc:resources mapping="/css/**" location="/statics/css/"/>
        <mvc:resources mapping="/js/**" location="/statics/js/"/>
        <mvc:resources mapping="/image/**" location="/statics/image/"/>
    
    
        <!-- 对模型视图名称的解析,即在模型视图名称添加前后缀(如果最后一个还是表示文件夹,则最后的斜杠不要漏了) 使用JSP-->
        <!-- 默认的视图解析器 在上边的解析错误时使用 (默认使用html)- -->
        <bean id="defaultViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
            <property name="prefix" value="/WEB-INF/view/"/><!--设置JSP文件的目录位置-->
            <property name="suffix" value=".jsp"/>
        </bean>

            <property name="resolveLazily" value="true"/>
        </bean>
    
    </beans>

    Spring的配置文件Application-context.xml文件的配置:

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

            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/util 
            http://www.springframework.org/schema/util/spring-util.xsd">
    
        <!--获取properties文件-->
        <context:property-placeholder location="classpath:jdbc.properties"/>
    
        <!--配置数据链接池-->
        <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">

            <property name="maxWait" value="${druid.max-wait}"/>
        </bean>
    
        <!--配置MyBatis的sessionFactory-->
        <bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
            <property name="dataSource" ref="dataSource"/>
            <!--如果有MyBatis的配置文件-->
            <!--<property name="configLocation" value="classpath:MyBatis-config.xml"/>-->

        </bean>
        <!--开启事物-->
        <tx:annotation-driven transaction-manager="transactionManager"/>
    
    
    </beans>

    四、类的编写:

    ApplicationController.java:

    package org.yoki.edu.main.controller;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestBody;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestParam;
    import org.springframework.web.bind.annotation.ResponseBody;
    import org.yoki.edu.main.service.CustomerService;
    
    /**
     * Created by SKY on 2017/6/4.
     */
    @Controller
    @RequestMapping("home")
    public class ApplicationController {
    
        @Autowired
        private CustomerService customerService ;
    
        @RequestMapping("/")
        @ResponseBody
        String home() {
            return "Hello World!";
        }
    
        @ResponseBody
        @RequestMapping("list")
        private String getList(){
            return customerService.getList() ;
        }
    
        @ResponseBody
        @RequestMapping("getById")
        private String getById(@RequestParam Integer id){
            return customerService.getById(id) ;
        }
    
        @ResponseBody
        @RequestMapping("listByMapper")
        private String getListByMapper(){
            return customerService.getListByMapper() ;
        }
    
        @ResponseBody
        @RequestMapping("getByIdByMapper")
        private String getByIdByMapper(@RequestParam Integer id){
            return customerService.getByIdByMapper(id) ;
        }
    
    }

    CustomerService.java:

    package org.yoki.edu.main.service;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;
    import org.yoki.edu.main.dao.CustomerDao;
    import org.yoki.edu.main.domain.Customer;
    
    import java.util.List;
    
    /**
     * Created by SKY on 2017/6/4.
     */
    @Service
    public class CustomerService {
    
        @Autowired
        private CustomerDao customerDao ;
    
        public String getList(){
            List<Customer> list =customerDao.getList() ;
            StringBuffer buf = new StringBuffer() ;
            for (Customer c : list){
                buf.append(buildDOM(c)) ;
            }
            return buf.toString();
        }
    
        public String getById(Integer id){
            List<Customer> list =customerDao.getList() ;
            Customer c = customerDao.getById(id) ;
            return buildDOM(c);
        }
    
        public String getListByMapper(){
            List<Customer> list =customerDao.getListByMapper() ;
            StringBuffer buf = new StringBuffer() ;
            for (Customer c : list){
                buf.append(buildDOM(c)) ;
            }
            return buf.toString();
        }
    
        public String getByIdByMapper(Integer id){
            List<Customer> list =customerDao.getList() ;
            Customer c = customerDao.getByIdByMapper(id) ;
            return buildDOM(c);
        }
    
        private String buildDOM(Customer c){
            StringBuffer buf = new StringBuffer() ;
            buf.append("<ul>") ;
            buf.append("<li>" + c.getUserName() + "</li>") ;
            buf.append("<li>" + c.getPswd() + "</li>") ;
            buf.append("<li>" + c.getCellphone() + "</li>") ;
            buf.append("<li>" + c.getEmail() + "</li>") ;
            buf.append("</ul>") ;
            return buf.toString() ;
        }
    
    }

    CustomerDao.java:

    package org.yoki.edu.main.dao;
    
    import org.apache.ibatis.session.SqlSession;
    import org.apache.ibatis.session.SqlSessionFactory;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Repository;
    import org.yoki.edu.main.domain.Customer;
    import org.yoki.edu.main.mapper.CustomerMapper;
    
    import javax.annotation.Resource;
    import java.util.List;
    
    /**
     * Created by SKY on 2017/6/4.
     */
    @Repository
    public class CustomerDao {
    
        @Autowired
        private SqlSessionFactory sessionFactory ;
    
        @Resource
        private CustomerMapper customerMapper ;
    
        //通过XML文件的Mapper的namespace + "." + (select、update、insert、delete)id,进行Mabatis的SQL操作,查看CustomerMapper.xml
        public List<Customer> getList(){
            SqlSession session = sessionFactory.openSession() ;
            List<Customer> list = session.selectList("this.is.customer.mapper.namespace" + ".selectAll") ;
            return list ;
         }
    
        //通过XML文件的Mapper的namespace + "." + (select、update、insert、delete)id,进行Mabatis的SQL操作,查看CustomerMapper.xml
        //通过Mapper类进行Mabatis的SQL操作,查看CustomerMapper.xml
         public Customer getById(Integer id){
            return sessionFactory.openSession().selectOne("this.is.customer.mapper.namespace" + ".selectById" , id) ;
         }
    
         //通过Mapper类进行Mabatis的SQL操作,查看CustomerMapperMapper.xml
        public List<Customer> getListByMapper(){
            SqlSession session = sessionFactory.openSession() ;
            List<Customer> list = customerMapper.selectAll() ;
            return list ;
        }
    
        //通过Mapper类进行Mabatis的SQL操作,查看CustomerMapperMapper.xml
        public Customer getByIdByMapper(Integer id){
            return customerMapper.selectById(id) ;
        }
    
    }

    BasicMapper.java(只是继承了一下MyBatis的Mapper及MySqlMapper接口):

    package org.yoki.edu.main.mapper;
    
    import tk.mybatis.mapper.common.Mapper;
    import tk.mybatis.mapper.common.MySqlMapper;
    
    /**
     * Created by SKY on 2017/6/4.
     */
    public interface BasicMapper<T> extends Mapper<T> , MySqlMapper<T>{
    }

    CustomerMapper.java

    package org.yoki.edu.main.mapper;
    
    import org.yoki.edu.main.domain.Customer;
    
    import java.util.List;
    
    /**
     * Created by SKY on 2017/6/4.
     */
    public interface CustomerMapper extends BasicMapper<Customer>{
    
        //对应CustomerMapperMapper.xml中的selectAll
        public List<Customer> selectAll() ;
    
        //对应CustomerMapperMapper.xml中的selectById
        public Customer selectById(Integer id) ;
    
    }

    两个*Mapper.xml配置文件基本一直:

    CustomerMapper.xml

    <?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">
    <!-- namespace随意内容 -->
    <mapper namespace="this.is.customer.mapper.namespace">
    
        <!-- 方法一 -->
        <!-- type属性对应与在MyBatis配置文件中typeAliases标签下定义的引用 -->
        <resultMap id="customerMapper" type="org.yoki.edu.main.domain.Customer">
            <!-- 属性名称<>列名 -->
            <id property="id" column="fd_id"/>
            <result column="fd_idCode" property="idCode"/>
            <result column="fd_userName" property="userName"/>
            <result column="fd_pswd" property="pswd"/>
            <result column="fd_cellphone" property="cellphone"/>
            <result column="fd_email" property="email"/>
        </resultMap>
    
        <!-- resultMap属性值对应 -->
        <select id="selectById" resultMap="customerMapper">
            select * from uc_customer where fd_id = #{id}
        </select>
    
        <select id="selectAll" resultMap="customerMapper">
            select * from uc_customer
        </select>
    
    </mapper>

    CustomerMapperMapper.xml

    <?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">
    
    <!-- 这里与CustomerMapper.xml有去吧  -->
    <!-- namespace对应Mapper类的全名 -->
    <mapper namespace="org.yoki.edu.main.mapper.CustomerMapper">
    
        <!-- 
            后面的与CustomerMapper.xml的一致 
        -->
    
    </mapper>
