import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.generator.AutoGenerator;
import com.baomidou.mybatisplus.generator.config.DataSourceConfig;
import com.baomidou.mybatisplus.generator.config.GlobalConfig;

import com.baomidou.mybatisplus.generator.config.StrategyConfig;
import com.baomidou.mybatisplus.generator.config.rules.DateType;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
import org.junit.Test;
/**
* @author
* @since 2018/12/13
*/
public class CodeGenerator {
@Test
public void run() {
// 1、创建代码生成器
AutoGenerator mpg = new AutoGenerator();
// 2、全局配置
GlobalConfig gc = new GlobalConfig();
String projectPath = System.getProperty("user.dir");
gc.setOutputDir(projectPath + "/src/main/java");
gc.setAuthor("testjava");
gc.setOpen(false); //生成后是否打开资源管理器
gc.setFileOverride(false); //重新生成时文件是否覆盖
gc.setServiceName("%sService"); //去掉Service接口的首字母I
gc.setIdType(IdType.ID_WORKER); //主键策略
gc.setDateType(DateType.ONLY_DATE);//定义生成的实体类中日期类型
gc.setSwagger2(true);//开启Swagger2模式
mpg.setGlobalConfig(gc);
// 3、数据源配置
DataSourceConfig dsc = new DataSourceConfig();
dsc.setUrl("jdbc:mysql://localhost:3306/guli");
dsc.setDriverName("com.mysql.jdbc.Driver");
dsc.setUsername("root");
dsc.setPassword("root");
dsc.setDbType(DbType.MYSQL);

19. 浮点数：^(-?\d+)(\.\d+)?$ 或 ^-?([1-9]\d*\.\d*|0\.\d*[1-9]\d*|0?\.0+|0)$
二、校验字符的表达式

11. 可以输入含有^%&',;=?$\"等字符：[^%&',;=?$\x22]+ 12 禁止输入含有~的字符：[^~\x22]+
三、特殊需求表达式
1. Email地址：^\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$
2. 域名：[a-zA-Z0-9][-a-zA-Z0-9]{0,62}(/.[a-zA-Z0-9][-a-zA-Z0-9]{0,62})+/.?
3. InternetURL：[a-zA-z]+://[^\s]* 或 ^http://([\w-]+\.)+[\w-]+(/[\w-./?%&=]*)?$
4. 手机号码：^(13[0-9]|14[5|7]|15[0|1|2|3|5|6|7|8|9]|18[0|1|2|3|5|6|7|8|9])\d{8}$
5. 电话号码("XXX-XXXXXXX"、"XXXX-XXXXXXXX"、"XXX-XXXXXXX"、"XXX-XXXXXXXX"、"XXXXXXX"和"XXXXXXXX)：^(\(\d{3,4}-)|\d{3.4}-)?\d{7,8}$
6. 国内电话号码(0511-4405222、021-87888822)：\d{3}-\d{8}|\d{4}-\d{7}
7. 身份证号(15位、18位数字)：^\d{15}|\d{18}$
8. 短身份证号码(数字、字母x结尾)：^([0-9]){7,18}(x|X)?$ 或 ^\d{8,18}|[0-9x]{8,18}|[0-9X]{8,18}?$
9. 帐号是否合法(字母开头，允许5-16字节，允许字母数字下划线)：^[a-zA-Z][a-zA-Z0-9_]{4,15}$
10. 密码(以字母开头，长度在6~18之间，只能包含字母、数字和下划线)：^[a-zA-Z]\w{5,17}$
11. 强密码(必须包含大小写字母和数字的组合，不能使用特殊字符，长度在8-10之间)：^(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).{8,10}$
12. 日期格式：^\d{4}-\d{1,2}-\d{1,2}
13. 一年的12个月(01～09和1～12)：^(0?[1-9]|1[0-2])$
14. 一个月的31天(01～09和1～31)：^((0?[1-9])|((1|2)[0-9])|30|31)$
15. 钱的输入格式：
16. 1.有四种钱的表示形式我们可以接受:"10000.00" 和 "10,000.00", 和没有 "分" 的 "10000" 和 "10,000"：^[1-9][0-9]*$
17. 2.这表示任意一个不以0开头的数字,但是,这也意味着一个字符"0"不通过,所以我们采用下面的形式：^(0|[1-9][0-9]*)$
18. 3.一个0或者一个不以0开头的数字.我们还可以允许开头有一个负号：^(0|-?[1-9][0-9]*)$
19. 4.这表示一个0或者一个可能为负的开头不为0的数字.让用户以0开头好了.把负号的也去掉,因为钱总不能是负的吧.下面我们要加的是说明可能的小数部分：^[0-9]+(.[0-9]+)?$
20. 5.必须说明的是,小数点后面至少应该有1位数,所以"10."是不通过的,但是 "10" 和 "10.2" 是通过的：^[0-9]+(.[0-9]{2})?$
21. 6.这样我们规定小数点后面必须有两位,如果你认为太苛刻了,可以这样：^[0-9]+(.[0-9]{1,2})?$
22. 7.这样就允许用户只写一位小数.下面我们该考虑数字中的逗号了,我们可以这样：^[0-9]{1,3}(,[0-9]{3})*(.[0-9]{1,2})?$
23 8.1到3个数字,后面跟着任意个 逗号+3个数字,逗号成为可选,而不是必须：^([0-9]+|[0-9]{1,3}(,[0-9]{3})*)(.[0-9]{1,2})?$
24. 备注：这就是最终结果了,别忘了"+"可以用"*"替代如果你觉得空字符串也可以接受的话(奇怪,为什么?)最后,别忘了在用函数时去掉去掉那个反斜杠,一般的错误都在这里
25. xml文件：^([a-zA-Z]+-?)+[a-zA-Z0-9]+\\.[x|X][m|M][l|L]$
26. 中文字符的正则表达式：[\u4e00-\u9fa5]
27. 双字节字符：[^\x00-\xff] (包括汉字在内，可以用来计算字符串的长度(一个双字节字符长度计2，ASCII字符计1))
28. 空白行的正则表达式：\n\s*\r (可以用来删除空白行)
29. HTML标记的正则表达式：<(\S*?)[^>]*>.*?</\1>|<.*? /> (网上流传的版本太糟糕，上面这个也仅仅能部分，对于复杂的嵌套标记依旧无能为力)
30. 首尾空白字符的正则表达式：^\s*|\s*$或(^\s*)|(\s*$) (可以用来删除行首行尾的空白字符(包括空格、制表符、换页符等等)，非常有用的表达式)
31. 腾讯QQ号：[1-9][0-9]{4,} (腾讯QQ号从10000开始)
32. 中国邮政编码：[1-9]\d{5}(?!\d) (中国邮政编码为6位数字)
33. IP地址：\d+\.\d+\.\d+\.\d+ (提取IP地址时有用)
34. IP地址：((?:(?:25[0-5]|2[0-4]\\d|[01]?\\d?\\d)\\.){3}(?:25[0-5]|2[0-4]\\d|[01]?\\d?\\d))

七、Springboot
① application.yml
server:
port: 8080
spring:
application:
name: reggie_take_out
datasource:
druid:
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://localhost:3306/reggie?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&useSSL=false&allowPublicKeyRetrieval=true
username: root
password: root
mybatis-plus:
configuration:
#在映射实体或者属性时，将数据库中表名和字段名中的下划线去掉，按照驼峰命名法映射
map-underscore-to-camel-case: true
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
global-config:
db-config:
id-type: ASSIGN_ID
八、web.xml配置
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
version="4.0">
</web-app>
九、maven修改成UTF-8格式
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
</properties>
十、pom.xml配置防止我们资源导出失败
<!--在build中配置resources，来防止我们资源导出失败的问题-->
<build>
<resources>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>true</filtering>
</resource>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>true</filtering>
</resource>
</resources>
</build>
十一、log4j.properties
#将等级为DEBUG的日志信息输出到console和file这两个目的地，console和file的定义在下面的代码
log4j.rootLogger=DEBUG,console,file
#控制台输出的相关设置
log4j.appender.console = org.apache.log4j.ConsoleAppender
log4j.appender.console.Target = System.out
log4j.appender.console.Threshold=DEBUG
log4j.appender.console.layout = org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=[%c]-%m%n
#文件输出的相关设置
log4j.appender.file = org.apache.log4j.RollingFileAppender
log4j.appender.file.File=./log/kuang.log
log4j.appender.file.MaxFileSize=10mb
log4j.appender.file.Threshold=DEBUG
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=[%p][%d{yy-MM-dd}][%c]%m%n
#日志输出级别
log4j.logger.org.mybatis=DEBUG
log4j.logger.java.sql=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.ResultSet=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
