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）.......;

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"="http://www.springframework.org/schema/mvc"="http://www.w3.org/2001/XMLSchema-instance"="http://www.springframework.org/schema/p"="http://www.springframework.org/schema/context"="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<!---->
<context:component-scan base-package="sy.controller" />
<!---->
<bean id="mappingJacksonHttpMessageConverter"="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html;charset=UTF-8</value>
</list>
</property>
</bean>
<!---->
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
<ref bean="mappingJacksonHttpMessageConverter" /><!---->
</list>
</property>
</bean>
<!---->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"="/"=".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"="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding">
<value>UTF-8</value>
</property>
<property name="maxUploadSize">
<value>32505856</value><!--单位：byte-->
</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
