一个简单的工具类，基于部分功能基于JDK11，使用Gradle进行构建，如果需要Maven版本，自行参照gradle文件进行修改
这个工具类包含有常规的字符串处理等功能，同时提供HTTP,websocket,mail,sms等服务，对基本框架的封装，适合新手使用
能够简单地获得日志对象，并且打印日志
Logger logger=SkyeLogger.getLogger();
logger.info("this is a log");使用Map来当作内存中的全局缓存使用
存入缓存
向缓存追加内容
CacheUtil.put("key","value");移除缓存
移除缓存内容
CacheUtil.remove("key");定时缓存
指定放入内容的时间，到达事件后将会被删除
CacheUtil.put("key1","value1",TimeUnit.SECONDS,3);修改文件的名字
修改文件名，"D:/test.png"--->"D:/test2.png"
FileUtil.changeFileName(new File("D:/test.png"),"test2");获得文件的拓展名
FileUtil.getFileExtensionName("D:/test.png")Get请求
发起一个Get请求
HttpResponse<String> response=HttpUtil.getRequest(
"https://www.baidu.com",
MapUtil.of("searchContent","testSearch"));
System.out.println(response);POST请求
发起一个POST请求
HttpResponse<String> response=HttpUtil.postRequest(
"https://www.baidu.com",
MapUtil.of("searchContent","testSearch"));
System.out.println(response);快速创建一个Map
MapUtil.of("key","value");
MapUtil.of("key1","value1","key2","value2");
MapUtil.of("key1","value1","key2","value2","key3","value3");
MapUtil.of("key1","value1","key2","value2","key3","value3","key4","value4");判断一系列的key是否在Map中
MapUtil.isKeyInMap(map,"key");加密
对字符串进行MD5加密，获得对应的加密值
Md5Util.getMd5String("123456");对jackson进行一定程度的封装，其他的转换见类文件
SerializeUtil.convertJsonToBeanByClass("{\"name\":"123"}",Username.class);参照guava的table,二维Map
// 由row,column确定value
Table<String, String,int>table = new Table();Object 转 Integer
Object 转 Integer，并设置转换失败默认值
Integer integer = Convert.toInt(123, 0);
System.out.print(integer);Object 转 String
Object 转 String，并设置转换失败默认值
String str = Convert.toStr(123, "");
System.out.print(str);自带默认时间转换格式yyyy-MM-dd HH:mm:ss
初始化
初始化一些待定的时间格式
DateTimeUtil.initGlobalDateFormatString("yyyy-MM-dd","yyyy-MM-dd hh:mm:ss","yyyy-MM-dd hh");字符串转换Date
将时间从字符串转换成Date对象，如果没有转入对应的格式字符串会调用默认的
DateTimeUtil.convertStringToDate("2022-11-27 10");Date转换为字符串
将时间转换为字符串，如果没有转入对应的格式字符串会调用默认的
DateTimeUtil.convertDateToString(new Date());获取虚拟机启动时间
// 获取当前虚拟机启动时间
DateTimeUtil.getServerStartDate();
System.out.println(DateTimeUtil.convertDateToString(serverStartDate)); // 2022-12-26 10:53:55获取当前日期
String dateStr = DateTimeUtil.dateNow();
System.out.println(dateStr); // 2022-12-26获取当前日期时间
String dateStr = DateTimeUtil.dateTimeNow();
System.out.println(dateStr); // 2022-12-26 11:12:35判断传入的时间是否符合表达式
//创建一个时间表达式
DateFilter dateFilter1=new DateFilter("this.year==2022 && this.month==11 && this.day==27");
//对时间进行匹配
dateFilter1.match(new Date());
DateFilter dateFilter3=new DateFilter("this.year==2023 || (this.month==11 && this.day==27)");
dateFilter3.match(new Date());判断图像是否是照片
ImageUtil.isImage("C:/test.png");将路径修改为jpg结尾
ImageUtil.convertImagePathToJpgSuffix("C:/test.png");将图像的质量进行压缩，减小大小，默认压缩倍率0.3
File file=new File("C:/test.png");
new ImageCompressor()
.setCompressRatio(0.2f)
.setFile(file)
.setNewPath("C:/test1.png")
.compress();
File file1=new File("C:/test1.png");
assert file1.length()<file.length();可以快速地生成和解码jwt
//编码jwt
String encode=JwtUtil.encode(
EncodeOrigin.getDefaultEncodeOrigin(),
MapUtil.of("key","value"));
//解码jwt
DecodeInfo decodeInfo=JwtUtil.decode(
encode,
DecodeOrigin.getDefaultEncodeOrigin(),
Map.of("key",String.class));正则校验
判断String字符串是否是邮件格式
MailUtil.isMailLegal("123456789@163.com");发送邮件
// 创建一个邮件会话
MailSession mailSession =new MailSession.MailSessionBuilder()
.setUsername("发送邮箱")
.setPassword("发送邮箱的密码")
.build();
// 创建一条邮件信息
SimpleMailMessage simpleMailMessage =new SimpleMailMessage.SimpleMailMessageBuilder()
.setMails(new String[] {"目标邮箱"})
.setContent("测试邮件")
.setSubject("测试主题")
.setMailSession(mailSession)
.build();
// 发送邮件
mailSession.sendMail(simpleMailMessage);正则校验
判断String字符串是否是手机号形式
SmsUtil.isPhoneNumberLegal("12345678901");简单接入腾讯短信平台
//创建腾讯短信平台
TencentSmsClient tencentSmsClient =new TencentSmsClient.TencentSmsClientBuilder()
.setSecretId("SecretId")
.setSecretKey("SecretKey")
.build();
//创建一条短信
TencentSmsRequest tencentSmsRequest =new TencentSmsRequest.TencentSmsRequestBuilder()
.setSdkAppId("SdkAppId")
.setSignName("SignName")
.setTemplateId("TemplateId")
.setTemplateContent(new String[] {"content"})
.build();
//发送短信
tencentSmsClient.sendSmsRequest(tencentSmsRequest, "targetPhoneNumber");生成指定位数的数字
StringUtil.getRandomNumber(6)生成指定位数的字符串
StringUtil.getRandomStr(6)分割字符串保留分隔符
String[] split = "http://www.baidu.com".split("\\.");
StringUtil.splitAndKeepMatchStr("http://www.baidu.com", "\\.");//将会获得 www.baidu
new SubstringOperator("http://www.baidu.com")
.setStartSign("//")
.setEndSign(".")
.build();//生成一个图片验证码
