项目任务1 创建并读取配置文件
这个项目就是不想写周报的时候偷懒用的，直接拿git记录生成日志用的。当前这部分是要先给个基础的配置数据，后面才好进行其他的。配的就是名称、项目路径、发送邮箱等
周报基础信息配置
ConfigData.java
这个类用于获取配置文件的基本信息，内容如注释所示

然后就要写一下配置文件，这个随意填一下就行,如下：
projectPaths=D:/program/mine/weekpaper
projectNames=周报
outputPath=D:/program/mine/weekpaper/out/
author=xx
career=xx
startDate=
endDate=
useEmail=1
emailSender=xx@xx.com
emailPassword=xx
emailReceiver=xx@xx.com
控制台日志配置
我们希望，使用一个单独的类来处理日志信息，用于配置日志颜色。红色代表错误，白色代表信息，如下：
LogUtil.java
❤🧡💛💚💙💜🤎🖤❤🧡💛💚💙💜🤎🖤❤🧡💛💚💙💜🤎🖤
import java.util.logging.Logger;
public class LogUtil {
private static Logger log = Logger.getGlobal();
static {
log.getParent().getHandlers()[0].setFormatter(new LoggerFormatter());
}
//控制台字体颜色设置：红色 [30m=[37m 对应不同控制台颜色
private static String consoleRed(){
return "\033[31m";
}
//控制台字体颜色设置：白色
private static String consoleWhite(){
return "\033[30m";
}
public static void severe(String msg){
log.severe(consoleRed()+msg);
}
public static void info(String msg){
log.info(consoleWhite()+msg);
}
}
❤🧡💛💚💙💜🤎🖤❤🧡💛💚💙💜🤎🖤❤🧡💛💚💙💜🤎🖤
LoggerFormatter.java
❤🧡💛💚💙💜🤎🖤❤🧡💛💚💙💜🤎🖤❤🧡💛💚💙💜🤎🖤
import sun.util.logging.LoggingSupport;
import java.io.PrintWriter;
import java.io.StringWriter;
import java.util.Date;
import java.util.logging.LogRecord;
import java.util.logging.SimpleFormatter;
public class LoggerFormatter extends SimpleFormatter {
private final String format = LoggingSupport.getSimpleFormat();
private final Date dat = new Date();
public synchronized String format(LogRecord var1) {
this.dat.setTime(var1.getMillis());
String var2;
if (var1.getSourceClassName() != null) {
var2 = var1.getSourceClassName();
if (var1.getSourceMethodName() != null) {
var2 = var2 + " " + var1.getSourceMethodName();
}
} else {
var2 = var1.getLoggerName();
}
String var3 = this.formatMessage(var1);
String var4 = "";
if (var1.getThrown() != null) {
StringWriter var5 = new StringWriter();
PrintWriter var6 = new PrintWriter(var5);
var6.println();
var1.getThrown().printStackTrace(var6);
var6.close();
var4 = var5.toString();
}
//从日志中摘取颜色信息，拼接到开头（不设置会导致前面的头部信息（日志名，类名，时间等）颜色不一致）
String color = var3.substring(0, "\033[31m".length());
return String.format(color + format, this.dat, var2, var1.getLoggerName(), var1.getLoggerName().toUpperCase(), var3, var4);
}
}

文件处理
- 获取文件标准路径
- 加载配置文件
FileUtil.java
❤🧡💛💚💙💜🤎🖤❤🧡💛💚💙💜🤎🖤❤🧡💛💚💙💜🤎🖤
import com.weekpaper.bean.ConfigData;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
public class FileUtil {
/**
* 获取文件标准绝对路径
* @param path
* @return
*/
public static String getFilePath(String path){
try {
return new File(path).getCanonicalPath();
} catch (IOException e) {
e.printStackTrace();
}
return "";
}
/**
* 加载配置文件
* @param configPath
* @return
*/
public static ConfigData loadConfigData(String configPath){
FileInputStream fis = null;
try {
fis = new FileInputStream(configPath);
ConfigData cd = new ConfigData();
cd.readObject(fis);
return cd;
} catch (IOException | ClassNotFoundException e) {
e.printStackTrace();
}finally {
if(fis!=null){

}
}
}
return null;
}
}

主程序加载配置文件
根据传参给出的配置文件地址，加载配置文件信息，加载不出来时，进行提示
❤🧡💛💚💙💜🤎🖤❤🧡💛💚💙💜🤎🖤❤🧡💛💚💙💜🤎🖤
public class WeekPaper {
public static void main(String[] args) {
if(args==null || args.length<1){
LogUtil.severe("找不到配置文件！");
System.exit(0);
}
//1.加载配置文件信息
ConfigData cd = FileUtil.loadConfigData(args[0]);
if(cd == null){
LogUtil.severe("配置内容有误！");
System.exit(0);
}else{
LogUtil.info("获取配置文件"+ FileUtil.getFilePath(args[0])+"成功！信息如下：");
LogUtil.info(cd.toString());
}
}
}
❤🧡💛💚💙💜🤎🖤❤🧡💛💚💙💜🤎🖤❤🧡💛💚💙💜🤎🖤
配置好配置文件地址：
运行结果：
