SpringMvc+Spring+Mybatis+Maven整合

一、建立数据库表，使用generator自动生成相关代码；

/*

SQLyog Ultimate v11.24 (32 bit)

MySQL - 5.1.62-community : Database - mydb

*********************************************************************

*/

/*!40101 SET NAMES utf8 */;

/*!40101 SET SQL_MODE=''*/;

/*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */;

/*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */;

/*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */;

/*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */;

CREATE DATABASE /*!32312 IF NOT EXISTS*/`mydb` /*!40100 DEFAULT CHARACTER SET gbk */;

USE `mydb`;

/*Table structure for table `photo` */

DROP TABLE IF EXISTS `photo`;

CREATE TABLE `photo` (

  `pid` int(11) NOT NULL AUTO_INCREMENT,

  `pname` varchar(50) NOT NULL,

  `fname` varchar(50) NOT NULL,

  `uname` varchar(50) NOT NULL,

  `fdate` date DEFAULT NULL,

  `tid` int(11) NOT NULL,

  PRIMARY KEY (`pid`),

  KEY `fk_tid` (`tid`),

  CONSTRAINT `fk_tid` FOREIGN KEY (`tid`) REFERENCES `type` (`tid`)

) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=gbk;

/*Data for the table `photo` */

insert  into `photo`(`pid`,`pname`,`fname`,`uname`,`fdate`,`tid`) values (1,'花好月圆','test.jpg','张飞','2016-07-19',1),(2,'奋斗奋斗','aa.jpg','房交会的积分','2016-07-19',12);

/*!40101 SET SQL_MODE=@OLD_SQL_MODE */;

/*!40014 SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS */;

/*!40014 SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS */;

/*!40111 SET SQL_NOTES=@OLD_SQL_NOTES */;

二、创建maven工程，并将生成的代码copy入工程中；

三、先整合Spring+Mybatis，在pom文件中引入相关的jar包；（http://search.maven.org）

需要在中央仓库中找到如下几个包导入，spring-core、mybatis、mybatis-spring、junit、mysql-connector-java（MySQL驱动包）、druid（配置数据源的jar包）.......;

        <session-timeout>15</session-timeout>

    </session-config>

</web-app>

五、测试Spring+Mybatis是否整合成功；

package sy.service;

import sy.model.Photo;

public interface PhotoServiceI {

    public Photo getPhotoById(Integer id);

}

package sy.service;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;

import sy.dao.PhotoMapper;

import sy.model.Photo;

@Service("PhotoServiceImp")

public class PhotoServiceImp implements PhotoServiceI {

    private PhotoMapper photo;

    public PhotoMapper getPhoto() {

        return photo;

    }

    @Autowired

    public void setPhoto(PhotoMapper photo) {

        this.photo = photo;

    }

    @Override

    public Photo getPhotoById(Integer id) {

        return  photo.selectByPrimaryKey(Integer.valueOf(id));

    }

}

Junit的测试方法；

import org.junit.*;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import sy.model.Photo;

import sy.service.PhotoServiceI;

public class testPhoto {

    PhotoServiceI pi;

    ApplicationContext ac;

    @Before

    public void before(){

        ac=new ClassPathXmlApplicationContext(new String[]{"spring.xml","spring-mybatis.xml"});

        pi= (PhotoServiceI)ac.getBean("PhotoServiceImp");

    }

    @Test

    public void getPhoto(){

        Photo photo = pi.getPhotoById(2);

        System.out.println(photo.getPname());

    }

}

spring的测试方法：

①：添加spring-test的jar包

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-test</artifactId>

            <version>3.2.0.RELEASE</version>

        </dependency>

②：要么在测试类的上面添加@RunWith(SpringJUnit4ClassRunner.class)要么让测试类继承自SpringJUnit4ClassRunner；

import org.junit.Test;

import org.junit.runner.RunWith;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.test.context.ContextConfiguration;

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import sy.model.Photo;

import sy.service.PhotoServiceI;

@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration(locations = { "classpath:spring.xml", "classpath:spring-mybatis.xml" })

public class testPhoto {

    PhotoServiceI pi;

    public PhotoServiceI getPi() {

        return pi;

    }

    @Autowired

    public void setPi(PhotoServiceI pi) {

        this.pi = pi;

    }

    @Test

    public void getPhoto(){

        Photo photo = pi.getPhotoById(2);

        System.out.println(photo.getPname());

    }

}

六、整合SpringMvc+Spring+Mybatis，在pom文件中导入SpringMVC相关的jar包；

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-webmvc</artifactId>

            <version>3.2.0.RELEASE</version>

        </dependency>

七、添加并修改 spring-mvc.xml 文件；

spring-mvc.xml文件

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

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans

    <context:component-scan base-package="sy.controller" />

    <!-- 避免IE执行AJAX时,返回JSON出现下载文件 -->

    <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">

        <property name="supportedMediaTypes">

            <list>

                <value>text/html;charset=UTF-8</value>

            </list>

        </property>

    </bean>

    <!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->

    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">

        <property name="messageConverters">

            <list>

                <ref bean="mappingJacksonHttpMessageConverter" /><!-- json转换器 -->

            </list>

        </property>

    </bean>

    <!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/" p:suffix=".jsp" />


    <!--配置文件的视图解析器，用于文件上传,其中ID是固定的：multipartResolver-->

    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

        <property name="defaultEncoding">

            <value>UTF-8</value>

        </property>

        <property name="maxUploadSize">

            <value>32505856</value><!--单位：byte 上传文件大小限制为31M，31*1024*1024 -->

        </property>

        <property name="maxInMemorySize">

            <value>4096</value>

        </property>

    </bean>

</beans>

八、添加controller并进行测试；

import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.PathVariable;

import org.springframework.web.bind.annotation.RequestMapping;

import sy.model.Photo;

import sy.service.PhotoServiceI;

@Controller

@RequestMapping("PhotoController")

public class PhotoController {

    PhotoServiceI pi;

    public PhotoServiceI getPi() {

        return pi;

    }

    @Autowired

    public void setPi(PhotoServiceI pi) {

        this.pi = pi;

    }

    @RequestMapping("getPhoto/{id}")

    public String getPhoto(@PathVariable Integer id,HttpServletRequest request){

        Photo photo = pi.getPhotoById(id);

        request.setAttribute("photo", photo);

        return "getPhoto";

    }

}

http://localhost:8080/XXX/PhotoController/getPhoto/1.do

注意事项：

①：测试时出现问题，一般在业务逻辑没问题的情况下，应该都是-----》jar包没导全、同一类型的jar包的版本不对应（尽量让版本统一）、jar包的maven加载顺序问题（将同一类型的jar包放到一起，高版本的放在前面，低版本的放在后面，那么即使后面的jar是低版本的，也会加载和前面jar版本一致的高版本的jar，主要是mybatis-spring依赖的jar包的问题，classloader）；

②：maven发布到Tomcat之前一定要让其编译下，用run as--> maven Install一下，然后发布到Tomcat
