PS:初学，想使用Maven配置一个SpringMVC的开发环境，照着网上的各种图文解说，配置了好久都没成功，有些写的不够详细，有些只有写一半，走了不少弯弯绕绕，踩了不少的坑，此文将正确配置成功的步骤全部记录下来。
1、环境
- IDEA 2017.3
- Maven 使用了 IDEA自带Maven，亦可以不用自带的（没什么大区别），不用IDEA自带的可以先去下载maven安装并设置。
Maven 安装配置 http://www.cnblogs.com/yangdaxian/p/8676373.html
- JDK 1.8 JDK需要先下载安装配置好
- Spring
- Mybatis
- MySQL 5.1.41 MySQL需要保证可用
- Tomcat 8
2、SSM整合
新建数据库表
CREATE TABLE `user` (
`id` varchar(10) NOT NULL,
`name` varchar(20) DEFAULT NULL,
`sex` varchar(5) DEFAULT NULL,
`age` varchar(3) DEFAULT NULL,
`address` varchar(100) DEFAULT NULL,
`phone` varchar(20) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8； INSERT INTO mytest.`user`(id, name, sex, age, address, phone) VALUES('', '张三', '男', '', '共住地球村', '');
INSERT INTO mytest.`user`(id, name, sex, age, address, phone) VALUES('', '李四', '男', '', '共住地球村', '');
INSERT INTO mytest.`user`(id, name, sex, age, address, phone) VALUES('', '洪五', '女', '', '共住地球村', '');
INSERT INTO mytest.`user`(id, name, sex, age, address, phone) VALUES('', '马六', '女', '', '共住地球村', '');
INSERT INTO mytest.`user`(id, name, sex, age, address, phone) VALUES('', '孙七', '女', '', '共住地球村', '');
INSERT INTO mytest.`user`(id, name, sex, age, address, phone) VALUES('', '赵八', '男', '', '共住地球村', '');
新建maven项目
- 选择好自己的JDK路径
- 设置项目的group id， artifactid， version等信息
- 设置maven仓库路径，我这边偷懒直接使用了idea自带的
- 项目名设置，然后Finish
- 等待后生成结构如下，右下角选择 Enable Auto-import 自动导入；
- 如果没有自动导入这个选项，pom.xml配置完成后可以在右侧边缘找到 Maven Projects 打开后点击第一个类似刷新的按钮进行下载
- 新建结构目录如下（若想要包分层结构显示在,上面齿轮那的第二行菜单，【Hide Empty Middle Packages】，将以选中的勾去掉就行）
- 新建的 java 文件 需要对它转一下， java文件夹上 右击 --> Make Diretorys as --> Sources Root (蓝色) /Test Sources Root (绿色)
【pom.xml 配置】
- 在<build>中添加如下信息
<!--plugins添加逆向工程插件-->
<plugins>
... 默认信息
<!--mybatis逆向工程插件-->
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>

配置 log4j.properties
- 在resources下新建，根据实际路径更改输出日志路径（D:/WorkSpace/idea_workSpase/springmvc/src/main/webapp/WEB-INF/log/log.txt）
#日志输出级别
log4j.rootLogger=debug,stdout,D,E #设置stdout的日志输出控制台
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
#输出日志到控制台的方式，默认为System.out
log4j.appender.stdout.Target = System.out
#设置使用灵活布局
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
#灵活定义输出格式
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} -[%p] method:[%c (%rms)] - %m%n #每天产生一个日志文件
log4j.appender.D=org.apache.log4j.DailyRollingFileAppender
#设置的输出日志
log4j.appender.D.File=D:/WorkSpace/idea_workSpase/springmvc/src/main/webapp/WEB-INF/log/log.txt
#设置的日志最大限制
log4j.appender.D.MaxFileSize=6000KB
#最多只保存20个备份文件
log4j.appender.D.MaxBackupIndex=20
#输出INFO级别以上的日志

log4j.appender.E.layout.ConversionPattern = %d{yyyy-MM-dd HH:mm:ss,SSS} -[%p] method:[%l (%rms)] - %m%n
配置 jdbc.properties
- 在resources下新建；需要更改本地驱动路径与数据库连接信息
jdbc.driverLocation=C:\\Users\\yq\\.m2\\repository\\mysql\\mysql-connector-java\\5.1.41\\mysql-connector-java-5.1.41.jar
jdbc.driverClasss=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://192.168.56.107:3306/mytest?useUnicode=true&characterEncoding=UTF-8
#声明使用username可能会与系统jvm冲突
jdbc.username=demo
jdbc.password=demo
- 驱动包路径查看方式：找到对应驱动后 右击 --> copy path
配置generatorConfig.xml
- mybatis逆向工程配置文件generatorConfig.xml，此配置文件名称不要改变
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration

http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd 识别不到的问题，可进行如下操作，File --> Setting 添加未识别的项
- 配置完成后的目录结构如下
测试逆向生成是否成功
配置完成后，可以测试逆向生成是否配置成功了~
点击左上角绿色的 + ，设置好 Name(自定义) 与 Command line
选中刚才设置的
，点击执行，如果正确配置了能看到在 dao 与 model中均生成了如下文件，这个User表是在generatorConfig.xml中配置的；如果出现错误了，排查下配置文件

测试查询数据库是否成功
在test --> dao 目录下新建一个测试类，测试下现在能否读取到数据库内容
package com.yq.dao; import com.yq.model.User;
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; @RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:spring-mybatis.xml"})
public class UserQueryTest { @Autowired
private UserMapper userMapper; @Test
public void queryUserName() {
String id = "1";
User user = userMapper.selectByPrimaryKey(id);
System.out.println(user.getName());
}
}
- webapp文件下创建index.jsp文件

Hello World！ 你的配置是正确哒！！！~~~
</body>

配置Tomcat
配置完成 
，启动看看~~
从数据库取数据来展示
- 现在上面已经配置成功了，接下去就要试试从数据库取数据来展示了
- 创建UserService
package com.yq.service; import com.yq.dao.UserMapper;
import com.yq.model.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service; @Service
public class UserService {
@Autowired
private UserMapper userMapper; public User getUserById(String id){
return userMapper.selectByPrimaryKey(id);
}
}
- 创建UserController
package com.yq.controller; import com.yq.model.User;
import com.yq.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView; @Controller
@RequestMapping("/userInfo")
public class UserController {
@Autowired
private UserService userService; @RequestMapping("/getUser")
public ModelAndView getUser(String id){
ModelAndView modelAndView = new ModelAndView();
User user = userService.getUserById(id);
modelAndView.addObject("userInfo",user);
modelAndView.setViewName("userInfo/getUser");
return modelAndView;
}
}
- 创建jsp文件，我们在spring-mvc.xml中配置了目录
因此我们要在 WEB-INF下新建个jsp文件夹
- getUser.jsp
