# 0、系统环境 #

1）Windows 10 企业版

2）JDK 1.8.0\_131

3）Eclipse Java EE IDE for Web Developers  Version: Neon.3 Release (4.6.3)

4）Tomcat 8.5

# 1、maven下载及配置 #

maven的下载地址：[http://maven.apache.org/download.cgi][http_maven.apache.org_download.cgi]

![438252-20170629214305868-274967637.png][]

下载后解压放在d:\\Java路径下

![438252-20170629214337258-181538293.png][]

在环境变量中，新增系统变量名：MAVEN\_HOME，变量值：D:\\Java\\maven

在Path中追加：%MAVEN\_HOME%\\bin;

在命令行窗口中输入：mvn –v，如果看见下图则说明maven安装配置完毕

# 2、maven仓库的设置 #

maven仓库默认位置在系统用户目录下的.m2目录中，类似下图

因为众所周知的原因，直接访问maven公共仓库的速度比较慢，所以推荐使用阿里的maven仓库镜像。编辑setting.xml文件，在mirrors节点下，新增如下内容，这样从仓库中下载jar包速度上会快很多。

<mirror>
           <id>nexus-aliyun</id>
           <mirrorOf>*</mirrorOf>
           <name>Nexus aliyun</name>
           <url>http://maven.aliyun.com/nexus/content/groups/public</url>
    </mirror>

# 3、eclipse整合maven #

设置eclipse自带maven整合工具，在Preferences中找到Maven节点，观察User Settings项的设置是否正确

![438252-20170630082749305-728877465.png][]

点击Installations节点，添加maven runtime

![438252-20170630082808305-135341987.png][]

# 4、创建maven项目时设置JDK #

**问题描述：eclipse创建maven项目时，显示的JDK默认版本为1.5，实际使用的JDK为1.8，如何修改？**

**解决方案：**找到本机maven仓库存放位置，比如：$\{user.home\}/.m2/路径，编辑settings.xml文件，在profiles节点下配置

# 5、使用maven创建SSM项目 #

1）选择Maven Project

![438252-20170630083001243-1040071794.png][]

2）点击Next，选择默认工作空间位置

![438252-20170630083011946-102050976.png][]

3）选择web类型

![438252-20170630083022477-1497680650.png][]

4）填写GroupID、ArtifactID

![438252-20170630083034461-1929443740.png][]

Group ID：相当于一个组织

Artifact ID：相当于这个组织下的一个具体项目

Packege：根据Group ID和Artifact ID生成一个默认的名称

5）创建出的maven项目如下图

6）问题描述：提示错误：

![438252-20170630083105571-2116022566.png][]

在eclipse中设置Server为Tomcat，注意JRE设置为安装的JDK的jre

![438252-20170630083116211-1721953961.png][]

在工程上右键，查看工程属性，找到Java Build Path，添加Server Runtime为Tomcat

![438252-20170630083129805-1456290285.png][]

![438252-20170630083228039-862286997.png][]

点击Finish后，项目工程变为下图

![438252-20170630083256758-328958397.png][]

7）pom.xml文件中修改build节点

<plugins>
           <plugin>
                  <groupId>org.apache.maven.plugins</groupId>
                  <artifactId>maven-compiler-plugin</artifactId>
                  <configuration>
                         <source>1.8</source>
                         <target>1.8</target>
                  </configuration>
           </plugin>
    </plugins>

# 6、下载ssm框架所需jar包 #

修改pom.xml内容为：

<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/maven-v4_0_0.xsd">

            </plugins>
        </build>
    </project>

保存后，可以看到相关jar包被下载至本地仓库

# 7、完善项目结构 #

因为服务端maven项目的标准结构有四个子包：src/main/java、src/main/resources、src/test/java、src/test/resources，这里缺少了src/test/resources，所以手动补上。

在项目中新建Source Folder

![438252-20170630090054493-1581777488.png][]

创建src/test/resources目录后，工程如下图所示

![438252-20170630090132571-1385274120.png][]

右键查看项目属性，点击Deployment Assembly，移除test和target

![438252-20170630090156243-980321419.png][]

移除后如下图

# 8、创建项目用的配置文件 #

![70][]

创建log4j.properties文件，内容如下：

log4j.rootLogger=DEBUG,MongoDB,Console,File
    
    #log4j.appender.MongoDB=org.log4mongo.MongoDbPatternLayoutAppender
    log4j.appender.MongoDB.Threshold=DEBUG
    log4j.appender.MongoDB.databaseName=applog
    log4j.appender.MongoDB.collectionName=appCallLog
    log4j.appender.MongoDB.hostname=192.168.2.79
    log4j.appender.MongoDB.port=27001
    log4j.appender.MongoDB.layout=org.log4mongo.MongoDbPatternLayout
    
    log4j.appender.Console=org.apache.log4j.ConsoleAppender
    log4j.appender.Console.Target=System.out
    log4j.appender.Console.layout = org.apache.log4j.PatternLayout
    log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
        
    log4j.appender.File = org.apache.log4j.RollingFileAppender
    log4j.appender.File.File = logs/ssm.log
    log4j.appender.File.MaxFileSize = 10MB
    log4j.appender.File.Threshold = ALL
    log4j.appender.File.layout = org.apache.log4j.PatternLayout
    log4j.appender.File.layout.ConversionPattern =[%p] [%d{	-MM-dd HH\:mm\:ss}][%c]%m%n

创建jdbc.properties文件，内容如下：

# 9、编写服务端代码 #

![438252-20170630090853118-948877059.png][]

编写User实体类，代码如下：

package cn.temptation.domain;
    
    /**
     * 用户信息
     */
    public class User {
        // 成员变量
        private Integer userid;
        private String username;
        private String password;
    
        // 构造函数
        public User() {
            super();
        }
    
        public User(Integer userid, String username, String password) {
            super();
            this.userid = userid;
            this.username = username;
            this.password = password;
        }
    
        // 成员方法
        public Integer getUserid() {
            return userid;
        }
    
        public void setUserid(Integer userid) {
            this.userid = userid;
        }
    
        public String getUsername() {
            return username;
        }
    
        public void setUsername(String username) {
            this.username = username;
        }
    
        public String getPassword() {
            return password;
        }
    
        public void setPassword(String password) {
            this.password = password;
        }
    }

编写UserController控制器，代码如下：

package cn.temptation.web;
    
    import javax.annotation.Resource;
    import javax.servlet.http.HttpSession;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.servlet.ModelAndView;
    
    import cn.temptation.dao.UserDao;
    import cn.temptation.domain.User;
    
    /**
     * 用户控制器
     */
    @Controller
    @RequestMapping(value = "/user")
    public class UserController {
        @Resource
        private UserDao userDao;
    
        @RequestMapping("/view")
        public String view() {
            return "main/login";
        }
    
        @RequestMapping("/indexview")
        public String index() {
            return "main/index";
        }
    
        @RequestMapping(value = "/login", method = RequestMethod.POST)
        public ModelAndView login(User model, HttpSession session) {
            User user = userDao.findByUsername(model.getUsername());
    
            if (user == null || !user.getPassword().equals(model.getPassword())) {
                return new ModelAndView("redirect:/login.jsp");
            } else {
                session.setAttribute("user", user);
                ModelAndView mav = new ModelAndView();
                mav.setViewName("index");
                return mav;
            }
        }
    }

编写UserDao数据访问层接口，代码如下：

package cn.temptation.dao;
    
    import cn.temptation.domain.User;
    
    public interface UserDao {
        public abstract User findByUsername(String username);
    }

编写UserMapper.xml数据访问层映射文件，代码如下：

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
            "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
    <mapper namespace="cn.temptation.dao.UserDao">
        <select id="findByUsername" parameterType="string" resultType="User">
            SELECT * FROM userinfo WHERE username=#{username}
        </select>
    </mapper>

# 10、编写客户端代码 #

![438252-20170630091227899-1070211122.png][]

编写login.jsp登录页，代码如下：

<%@ 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=UTF-8">
    <title>登录</title>
    </head>
    <body>
    <form action="user/login" method="post">
    <label>账号：</label>
    <input type="text" id="txtUsername" name="username" placeholder="请输入账号" /><br/>
    <label>密码：</label>
    <input type="password" id="txtPassword" name="password" placeholder="请输入密码" /><br/>
    <input type="submit" value="提交" />
    <input type="reset" value="重置" />
    </form>
    </body>
    </html>

编写index.jsp主页，代码如下：

# 11、使用maven构建项目 #

在项目上右键，找到Maven属性的Update Project，也可以Alt+F5操作

![438252-20170630091650133-214409937.png][]

修改项目编译路径为JRE系统类库，否则后续操作出错

![438252-20170630091701055-119101564.png][]

项目上右键，找到Run As属性，找到Maven install

![438252-20170630091714211-10728364.png][]

点击执行，结果如下说明构建成功

![438252-20170630091806836-1933605491.png][]

项目运行还是使用web工程的部署运行方式

![438252-20170630091824196-1056209465.png][]

运行项目，观察是否报错

![438252-20170630091836149-32951596.png][]

登录页面

![438252-20170630091848852-2063860413.png][]

登录成功，跳转到主页

![438252-20170630091859149-1615205040.png][]
