一、思路：
(一) Dao层与Service层：
applicationContext.xml。
a) 数据库连接池
b) 整合jpa
c) 配置@service文件扫描器。
d) 配置事务管理管理器，开启事务注解
e) 配置jpa扫描器
(二)Controller层：
Springmvc.xml
1、包扫描器，扫描@Controller注解的类。
2、配置注解驱动。
3、视图解析器。
(三)web.xml
1. 配置spring容量监听器
2. 配置前端控制器
二、构建项目
（一）构建maven项目，添加依赖

（四）springMVC的配置
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:context="http://www.springframework.org/schema/context" 5 xmlns:mvc="http://www.springframework.org/schema/mvc" 6 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd 7 http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd 8 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"> 9 10 <!--配置controller扫描--> 11 <context:component-scan base-package="com.cenobitor.controller"/> 12 13 <!-- 注解驱动 --> 14 <mvc:annotation-driven/> 15 16 <!--<!–自定义转换器配置模板–> 17 <!–使用自定义转换器–> 18 <mvc:annotation-driven conversion-service="myConverter" /> 19 20 <!– 定义转换器 –> 21 <bean id="myConverter" class="org.springframework.format.support.FormattingConversionServiceFactoryBean"> 22 <property name="converters"> 23 <set> 24 <!– 日期转换器 –> 25 <bean class="com.cenobitor.converter.DateConverter" /> 26 </set> 27 </property> 28 </bean>--> 29 30 <!-- 配置多媒体解析器 --> 31 <!-- 注意：这里的id只能是multipartResolver --> 32 <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> 33 <!-- 限定文件最大上传大小为：8MB --> 34 <property name="maxUploadSize" value="8388608" /> 35 </bean> 36 37 <!--可减少简写路径名--> 38 <!--<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 39 <!– 配置逻辑视图的前缀 –> 40 <property name="prefix" value="/WEB-INF/views/"/> 41 <property name="suffix" value=".jsp"/> 42 </bean>--> 43 </beans>
（五）log4j配置文件，位于resources包下：
1 log4j.rootLogger=DEBUG, Console
2 #Console
3 log4j.appender.Console=org.apache.log4j.ConsoleAppender
4 log4j.appender.Console.layout=org.apache.log4j.PatternLayout
5 log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n
6 log4j.logger.java.sql.ResultSet=INFO
7 log4j.logger.org.apache=INFO
8 log4j.logger.java.sql.Connection=DEBUG
9 log4j.logger.java.sql.Statement=DEBUG
10 log4j.logger.java.sql.PreparedStatement=DEBUG
三、 图片上传预览
1、创建pojo，自动建表
1 package com.cenobitor.pojo; 2 3 import lombok.Data; 4 import javax.persistence.*; 5 6 /** 7 * @Description: 8 * @Date: Created in 11:05 AM 2018/5/1 9 * @Author: Cenobitor 10 * @Modified By: 11 */ 12 @Data 13 @Entity 14 @Table(name = "t_pic") 15 public class Pic { 16 17 @Id 18 @GeneratedValue 19 @Column(name = "t_id") 20 private Integer id; 21 @Column(name = "t_name") 22 private String name; 23 @Column(name = "t_url") 24 private String url; 25 26 public Pic(String name, String url) { 27 this.name = name; 28 this.url = url; 29 } 30 31 public Pic() { 32 } 33 }
2、设置文件存储的虚拟路径
2、创建上传页面
1 <!DOCTYPE html> 2 <html lang="en"> 3 <head> 4 <meta charset="UTF-8"> 5 <title>上传图片</title> 6 </head> 7 <body> 8 <form id="upload" action="/uploadpic.action" method="post" enctype="multipart/form-data"> 9 <input type="file" name="picFile"/> 10 <br/> 11 <input type="submit" value="提交"/> 12 </form> 13 </body> 14 </html>
3、创建Controller类
1 package com.cenobitor.controller;
2
3 import com.cenobitor.service.UploadFileService;
4 import org.springframework.beans.factory.annotation.Autowired;
5 import org.springframework.stereotype.Controller;
6 import org.springframework.web.bind.annotation.*;
7 import org.springframework.web.multipart.MultipartFile;
8
9 @Controller
10 public class UploadFileController {
11
12 @Autowired
13 private UploadFileService uploadFileService;
14
15 //图片上传用MultipartFile接收文件,其中参数名要表单中的文件名一致
16 @RequestMapping("/uploadpic")
17 public String uploadPic(MultipartFile picFile) throws Exception {
18 String picUrl = uploadFileService.UploadPic(picFile);
19 if (picUrl == null){
20 return "redirect:error.html";
21 }
22 //重定向预览图片
23 return "redirect:"+picUrl;
24 }
25 }
4、创建service层
1 public interface UploadFileService {
2 public String UploadPic(MultipartFile picFile);
3 }
1 package com.cenobitor.service.impl; 2 3 import com.cenobitor.dao.PicRepository; 4 import com.cenobitor.pojo.Pic; 5 import com.cenobitor.service.UploadFileService; 6 import org.springframework.beans.factory.annotation.Autowired; 7 import org.springframework.stereotype.Service; 8 import org.springframework.transaction.annotation.Transactional; 9 import org.springframework.web.multipart.MultipartFile; 10 import java.io.File; 11 import java.io.IOException; 12 import java.util.UUID; 13 14 @Service 15 @Transactional 16 public class UploadFileServiceImpl implements UploadFileService { 17 18 19 @Autowired 20 private PicRepository repository; 21 22 @Override 23 public String UploadPic(MultipartFile picFile) { 24 try { 25 // 图片新名字 26 String name = UUID.randomUUID().toString(); 27 // 图片原名字 28 String oldName = picFile.getOriginalFilename(); 29 // 后缀名 30 String exeName = oldName.substring(oldName.lastIndexOf(".")); 31 //保存图片路径为绝对路径 32 File pic = new File("/Users/Shared/jpg/" + name + exeName); 33 // 保存图片到本地磁盘 34 picFile.transferTo(pic); 35 36 //保存数据到数据库中 37 repository.save(new Pic(name,"../jpg/"+name+exeName)); 38 return "/jpg/"+name+exeName; 39 40 } catch (IOException e) { 41 e.printStackTrace(); 42 return null; 43 } 44 } 45 }
5、创建dao层
1 package com.cenobitor.dao; 2 3 import com.cenobitor.pojo.Pic; 4 import org.springframework.data.jpa.repository.JpaRepository; 5 6 public interface PicRepository extends JpaRepository<Pic,Integer> { 7 8 }
6、项目的目录结构
Spring+SpringMVC+SpringDataJpa整合
