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>

  </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"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
                        http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
                         http://www.springframework.org/schema/context
                        http://www.springframework.org/schema/context/spring-context-3.2.xsd
                        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>

    <!-- springmvc文件上传需要配置的节点-->
    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

        <property name="defaultEncoding" value="UTF-8"/>
        <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/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-->

    <!--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="dataSource" ref="dataSource"/>
    </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>    
View Code

 

五、输出结果
