## 项目简介 ##

### 功能点： ###

*  分页显示
 *  数据校验  
    – jquery前端校验以及JSR303后端校验
 *  Ajax请求
 *  Rest风格的URI：使用HTTP协议请求的动词，来表示对资源的操作（GET（查询）、POST（新增）、PUT（修改）、DELETE（删除））

### 技术点： ###

*  基础框架 ssm
 *  数据库 mysql
 *  前端框架 bootstrap
 *  maven做项目的依赖管理
 *  使用pagehelper做分页功能
 *  Mabatis Generator逆向工程

## 搭建基础环境 ##

### 创建Maven工程： ###

*  首先需要在window-》Preference-》Maven里面的installation里面选择自己安装的maven版本。点击maven根菜单，点选如下选项，下载源码与javadoc：  
    ![这里写图片描述][SouthEast]
 *  New->Project->Maven Project:  
    ![这里写图片描述][SouthEast 1]  
    ![这里写图片描述][SouthEast 2]
 *  这里的项目没有配置文件，手动配置：右键Properties-》Project Facets-》把动态网站模块（Dynamic Web Module）先去掉Apply之后再添加，出现further选项：  
    ![这里写图片描述][SouthEast 3]
 *  选择项目路径，生成web.xml：  
    ![这里写图片描述][SouthEast 4]  
    生成的目录如下：  
    ![这里写图片描述][SouthEast 5]
 *  继续修改配置，在\{maven\_path\}/conf路径下找到settings.xml，修改镜像为阿里云：  
    `<mirror> <id>alimaven</id> <name>aliyun maven</name> 　　<url>http://maven.aliyun.com/nexus/content/groups/public/</url> <mirrorOf>central</mirrorOf> </mirror>`
 *  在配置文件中添加profiles的选项(默认jdk为1.8)：`<id>jdk18</id> <activation> <activeByDefault>true</activeByDefault> <jdk>1.8</jdk> </activation> <properties> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion> </properties>`
 *  这里一般还有一些关于jdk版本的问题，你可能会发现你每次使用项目右键maven-》update project之后java build path中的jdk版本会变回原版本，这个时候使用上一步之后在update project可以解决这个问题，当然，网上还有其他的办法可以不修改maven的配置，在pom.xml中添加：

<plugins>
    <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.3.2</version>
    <configuration>
    <source>1.8</source>
    <target>1.8</target>
    <encoding>UTF-8</encoding>
    </configuration>
    </plugin>
    </plugins>

*  在eclipse-》window-》Preference中选择maven-》User Settings-》选中修改的配置文件。
 *  至此，maven工程创建完毕。

### 引入项目依赖包 ###

项目jar包包括：  
\- spring  
\- mybatis  
\- springmvc  
\- 数据库连接池、驱动包  
\- 其他（JSTL、servlet-api、junit）

*  打开pom.xml引入项目依赖包：

<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">

                <version>4.12</version>
            </dependency>
        </dependencies>
    </project>

*  引入bootstrap前端框架与jquery：  
    – 打开bootstrp官网，下载bootstrp。  
    – 在webapp目录下创建static文件夹保存静态资源，将解压后的bootstrp包放在static下：  
    ![这里写图片描述][SouthEast 6]
 *  在webapp下创建一个jsp文件（index.jsp）使用bootstrap框架和jquery：

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
    <title>Insert title here</title>
    
    <script type="text/javascript" src="static/js/jquery-1.12.4.js"></script>
    
    <link href="static/bootstrap/css/bootstrap.min.css" rel="stylesheet">
    
    <script src="static/bootstrap/js/bootstrap.min.js" ></script>
    </head>
    <body>
    </body>
    </html>

### 编写ssm整合的关键配置文件（web.xml,spring/springmvc/mybatis的配置文件）注意，这里为了方便编写，可以下载对应的插件，点击help-》Eclipse Marketplace:(如spring对应的插件为spring tool suite) ###

*  web.xml:
