使用常见的工具类来完成常见的细节操作：
IOUtils
IOUtils： Apache Commons IO用来处理输入-输出流
详情介绍
依赖
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.4</version>
</dependency>
import org.apache.commons.io.IOUtils;
IOUtils 提供的一些常见的方法：
- closeQuietly ： 它将无条件的关闭一个可被关闭的对象而不抛出任何异常
- copy： 这个方法将内容按字节从一个InputStream对象复制到一个OutputStream对象，并返回复制的字节数。同样有一个方法支持从Reader对象复制到Writer对象
- IOUtils.toInputStream(A ,“utf-8”): 创建一个InputStream
FileUtils
FileUtils是 commons-io包下的FileUtils
详情介绍： 连接
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.3.3</version>
</dependency>
import org.apache.commons.io.FileUtils;
提供了以下的方法：
- copyFile(File srcFile, File destFile)：拷贝文件夹
2.copyDirectory(File srcDir, File destDir):拷贝目录及文件 - deleteQuietly(File file)： 删除指定文件，从不引发异常
- deleteDirectory(File directory)递归删除目录
5.cleanDirectory(File directory)：清空目录
StringUtils
StringUtils类在操作字符串是安全的，不会报空指针异常，也正因此，在操作字符串时使用StringUtils相比使用原生的String会更加安全。
详情介绍
依赖
org.apache.commons commons-lang3 3.3.2 import org.apache.commons.lang3.StringUtils;
StringUtils提供的一些常见方法
1.判断字符串是否为空： isEmpty（isNotEmpty）和 isBlank(isNotBlank)
isBlank：判断更严谨，包含的有空串("")、空白符(空格""，" “，制表符”\t"，回车符"\r"，"\n"等)以及null值；
isEmpty：包含是空串("")和null值，不包含空白符；
2. 移除单个字符： StringUtils.remove(String str, String remove);
3.删除所有空白符： deleteWhitespace(String str)
4. 比较两个字符串：StringUtils.equals("", “”); //可以进行空置null
StringUtils.equalsIgnoreCase(“ss”, “Ss”); //不区分大小写–结果是true
DateUtils
DateUtils提供了一些常用的时间相关的格式转换操作
/**
* 提供时间先关的常用方法
*/
public class DateUtils {
//当前时间
public static Date DATE_NOW=new Date();
/**
* 得到完整的时间戳，格式:yyyyMMddHHmmssSSS(年月日时分秒毫秒)
* @return 完整的时间戳
*/
public static String getFullTimeStamp(){
return new SimpleDateFormat("yyyyMMddHHmmssSSS").format(new Date()) ;
}
/**
* 得到简单的时间戳，格式:yyyyMMdd(年月日)
* @return 简单的时间戳
*/
public static String getSimpleTimeStamp(){
return new SimpleDateFormat("yyyyMMdd").format(new Date()) ;
}
/**
* 根据指定的格式得到时间戳
* @param pattern 指定的格式
* @return 指定格式的时间戳
*/
public static String getTimeStampByPattern(String pattern){
return new SimpleDateFormat(pattern).format(new Date()) ;
}
/**
* 得到当前日期格式化后的字符串，格式：yyyy-MM-dd(年-月-日)
* @return 当前日期格式化后的字符串
*/
public static String getTodayStr(){
return new SimpleDateFormat("yyyy-MM-dd").format(new Date()) ;
}
/**
* 时间戳，格式:yyyy-MM-dd HH:mm:ss(年-月-日 时：分：秒)
* @return 简单的时间戳
*/
public static String getDateTimeStamp(Date date){
return new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(date) ;
}
public static Date getDateByString(String str){
SimpleDateFormat sim=new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
Date dateTime = null;
try {
dateTime = sim.parse(str);
} catch (ParseException e) {
e.printStackTrace();
}
return dateTime;
}
}
