标签:nal   private   xsd   tco   使用   des   classpath   imp   mpi   

一、思路:

(一) Dao层:

1、 SqlMapConfig.xml,空文件即可。需要文件头。
2、 applicationContext_dao.xml。

a) 数据库连接池
b) SqlSessionFactory对象,需要spring和mybatis整合包下的。
c) 配置mapper文件扫描器。

(二)Service层:

1、applicationContext_service.xml包扫描器,扫描@service注解的类。
2、applicationContext_trans.xml配置事务。

(三)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。

(四)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

34     </aop:config>
35 </beans>

(三)web.xml 的配置

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 3          xmlns="http://java.sun.com/xml/ns/javaee"
 4          xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
 5             http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
 6          id="WebApp_ID" version="2.5">
 7     <welcome-file-list>
 8         <welcome-file>index.jsp</welcome-file>
 9     </welcome-file-list>
10 
11     <!-- spring配置文件路径 -->
12     <context-param>
13         <param-name>contextConfigLocation</param-name>
14         <param-value>classpath:/spring/applicationContext_*.xml</param-value>
15     </context-param>
16 
17     <!-- 解决post乱码问题 -->
18     <filter>
19         <filter-name>encoding</filter-name>
20         <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
21         <!-- 设置编码参是UTF8 -->
22         <init-param>
23             <param-name>encoding</param-name>
24             <param-value>UTF-8</param-value>

26     </filter>
27     <filter-mapping>
28         <filter-name>encoding</filter-name>
29         <url-pattern>/*</url-pattern>
30     </filter-mapping>
31 
32     <listener>
33         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
34     </listener>
35 
36     <!-- 配置SpringMvc 前端控制器 -->
37     <servlet>
38         <servlet-name>springmvc</servlet-name>
39         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
40         <!--指定SpringMvc 配置文件-->
41         <!-- springmvc的配置文件默认路径是 /WEB-INF/${servlet-name}_servlet.xml -->
42         <init-param>
43             <param-name>contextConfigLocation</param-name>
44             <param-value>classpath:spring/springmvc.xml</param-value>
45         </init-param>
46     </servlet>
47     <servlet-mapping>
48         <servlet-name>springmvc</servlet-name>
49         <url-pattern>*.action</url-pattern>
50     </servlet-mapping>
51 
52 </web-app>

(四)MyBatis的配置文件,实体类和对应的映射文件由通用Mapper生成,在此采用手动创建方式(详细见下文件图片上传案例)

此处建文件,配置mybatis分页插件即可:

 1 <?xml version="1.0" encoding="UTF-8" ?>
 2 <!DOCTYPE configuration
 3         PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
 4         "http://mybatis.org/dtd/mybatis-3-config.dtd">
 5 <configuration>
 6     <plugins>
 7         <!-- com.github.pagehelper为PageHelper类所在包名 -->
 8         <plugin interceptor="com.github.pagehelper.PageHelper">
 9             <!-- 设置数据库类型 Oracle,Mysql,MariaDB,SQLite,Hsqldb,PostgreSQL六种数据库-->
10             <property name="dialect" value="mysql"/>
11         </plugin>
12     </plugins>
13 
14 </configuration>

(五)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     <!--&lt;!&ndash;自定义转换器配置模板&ndash;&gt;

21     <bean id="myConverter" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
22         <property name="converters">
23             <set>
24                 &lt;!&ndash; 日期转换器 &ndash;&gt;
25                 <bean class="com.cenobitor.converter.DateConverter" />
26             </set>
27         </property>
28     </bean>-->
29 
30     <!-- 配置多媒体解析器,用于上传等的配置,如果是纯文本则无需配置 -->
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         &lt;!&ndash; 配置逻辑视图的前缀 &ndash;&gt;
40         <property name="prefix" value="/WEB-INF/views/"/>
41         <property name="suffix" value=".jsp"/>
42     </bean>-->
43 </beans>

(六)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、创建表以及pojo

1 CREATE TABLE `pic` (
2   `id` int(11) NOT NULL AUTO_INCREMENT,
3   `name` varchar(255) DEFAULT NULL,
4   `url` varchar(255) DEFAULT NULL,
5   PRIMARY KEY (`id`)
6 ) ENGINE=InnoDB AUTO_INCREMENT=7 DEFAULT CHARSET=utf8
 1 package com.cenobitor.pojo;
 2 
 3 import lombok.Data;
 4 
 5 /**
 6  * @Description:
 7  * @Date: Created in 11:05 AM 2018/5/1
 8  * @Author: Cenobitor
 9  * @Modified By:
10  */
11 @Data
12 public class Pic {
13 
14     private Integer id;
15     private String name;
16     private String url;
17 
18     public Pic(String name, String url) {
19         this.name = name;
20         this.url = url;
21     }
22 
23     public Pic() {
24     }
25 }

2、设置文件存储的虚拟路径

技术分享图片

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.mapper.PicMapper;
 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     @Autowired
19     private PicMapper picMapper;
20 
21     @Override
22     public String UploadPic(MultipartFile picFile) {
23         try {
24             // 图片新名字
25             String name = UUID.randomUUID().toString();
26             // 图片原名字
27             String oldName = picFile.getOriginalFilename();
28             // 后缀名
29             String exeName = oldName.substring(oldName.lastIndexOf("."));
30             //保存图片路径为绝对路径
31             File pic = new File("/Users/Shared/jpg/" + name + exeName);
32             // 保存图片到本地磁盘
33             picFile.transferTo(pic);
34 
35             //保存数据到数据库中
36             picMapper.add(new Pic(name,"../jpg/"+name+exeName));
37             return "/jpg/"+name+exeName;
38 
39         } catch (IOException e) {
40             e.printStackTrace();
41             return null;
42         }
43     }
44 }

5、创建dao层(mapper层)

1 package com.cenobitor.mapper;
2 
3 import com.cenobitor.pojo.Pic;
4 
5 public interface PicMapper {
6     //添加图片
7     int add(Pic pic);
8 
9 }
 1 <?xml version="1.0" encoding="UTF-8" ?>
 2 <!DOCTYPE mapper
 3         PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
 4         "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
 5 <!--namespace为对应的mapper类的全路径名-->
 6 <mapper namespace="com.cenobitor.mapper.PicMapper">
 7 
 8     <!-- 添加 -->
 9     <!-- id为对应的方法名, parameterType为入参的全路径名-->
10     <insert id="add" parameterType = "com.cenobitor.pojo.Pic">
11         insert into
12         pic(name,url)
13         values
14         (#{name},#{url});
15     </insert>
16 
17 </mapper>

6、项目的目录结构
