本项目使用环境：
- 开发工具：eclipse 4.4.1
- springboot: 1.5.2
- jdk：1.8.0_161
- maven:3.2.5
功能： mybatis generator 自动生成代码插 件
1.创建一个springBoot 项目
1.1 项目目录完成的整体如下：
1.2 查看pom.xml 文件结构如下：
<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">

spring:
application: name: sortcen-api-sell datasource: name: test url: jdbc:mysql://127.0.0.1:3306/db_sort_center username: root password: 12345 # 使用druid数据源 type: com.alibaba.druid.pool.DruidDataSource driver-class-name: com.mysql.jdbc.Driver filters: stat maxActive: 20 initialSize: 1 maxWait: 60000 minIdle: 1 timeBetweenEvictionRunsMillis: 60000 minEvictableIdleTimeMillis: 300000 validationQuery: select 'x' testWhileIdle: true testOnBorrow: false testOnReturn: false poolPreparedStatements: true maxOpenPreparedStatements: 20 server: port: 2001 eureka: client: service-url: defaultZone : http://localhost:8081/eureka/mybatis:
mapper-locations: classpath:mapping/*.xml type-aliases-package: com.winter.model#pagehelper分页插件
pagehelper: helperDialect: mysql reasonable: true supportMethodsArguments: true params: count=countSql1.4 创建数据库
CREATE DATABASE mytest;CREATE TABLE t_user( user_id INT NOT NULL PRIMARY KEY AUTO_INCREMENT, user_name VARCHAR(255) NOT NULL , password VARCHAR(255) NOT NULL , phone VARCHAR(255) NOT NULL) ENGINE=INNODB AUTO_INCREMENT=1000 DEFAULT CHARSET=utf8;
1.5 使用mybatis generator 自动生成代码：
配置pom.xml中generator 插件所对应的配置文件 ${basedir}/src/main/resources/generator/generatorConfig.xml
generatorConfig.xml 文件配置如下：
配置好后，通过eclipse 中的maven build 命令执行自动生成代码，具体操作如下图：
在eclipse 中的项目文件-右单击--》Run as ---->Maven build 里面输入 命令：mybatis-generator:generate 去执行自动生成实体类和相关的查询
在里面输入如下图的内容：
选择Apply ，点击run 执行。
