二、mybatis-plus代码生成器

package com.example.demo;

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.PackageConfig;
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);
        mpg.setDataSource(dsc);

        // 4、包配置
        PackageConfig pc = new PackageConfig();
        pc.setModuleName("edu"); //模块名
        pc.setParent("com.example.demo");
        pc.setController("controller");
        pc.setEntity("entity");
        pc.setService("service");
        pc.setMapper("mapper");
        mpg.setPackageInfo(pc);

        // 5、策略配置
        StrategyConfig strategy = new StrategyConfig();
        strategy.setInclude("edu_teacher");
        strategy.setNaming(NamingStrategy.underline_to_camel);//数据库表映射到实体的命名策略
        strategy.setTablePrefix(pc.getModuleName() + "_"); //生成实体时去掉表前缀

        strategy.setColumnNaming(NamingStrategy.underline_to_camel);//数据库表字段映射到实体的命名策略

        mpg.setStrategy(strategy);


        // 6、执行
        mpg.execute();
    }
}

三、swagger

package com.jegoel.servicebase.config;

import com.google.common.base.Predicates;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket webApiConfig(){
        return new Docket(DocumentationType.SWAGGER_2)
                .groupName("webApi")
                .apiInfo(webApiInfo())
                .select()
                .paths(Predicates.not(PathSelectors.regex("/admin/.*")))
                .paths(Predicates.not(PathSelectors.regex("/error.*")))
                .build();
    }

    private ApiInfo webApiInfo(){
        return new ApiInfoBuilder()
                .title("标题")
                .description("测试接口页面")
                .version("1.0")
                .contact(new Contact("jegole", "http://localhost.com:8001", "123@qq.com"))
                .build();
    }
}

四、正则表达式

一、校验数字的表达式
1. 数字:^[0-9]*$

2. n位的数字:^\d{n}$

3. 至少n位的数字:^\d{n,}$

4. m-n位的数字:^\d{m,n}$

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
 

1. 汉字:^[\u4e00-\u9fa5]{0,}$

2. 英文和数字:^[A-Za-z0-9]+$ 或 ^[A-Za-z0-9]{4,40}$

10. 中文、英文、数字但不包括下划线等符号:^[\u4E00-\u9FA5A-Za-z0-9]+$ 或 ^[\u4E00-\u9FA5A-Za-z0-9]{2,20}$
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))

# Compiled class file
*.class

# Log file
*.log

# BlueJ files
*.ctxt

# Mobile Tools for Java (J2ME)
.mtj.tmp/

# Package Files #

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

#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
