Proguard使用最新，最全教程，亲自试验
最近公司有一個項目，是外包項目，由于對方也有技術人員，出于技術上的保密，需要對class文件進行二次處理，于是網上找了好久，只發現Proguard是用的最廣泛而且網上資料最多的。由于不是純JAVA項目，而是WEB項目，涉及到大量的配置文件，所以用這個工具稍顯吃力，于是開始研究這玩意，花了好長一段時間，重復試驗了N次，終于整出來了，下面總結一下我的經驗。。
首先我介紹下我要混淆的項目框架是jeecg+easyui+spring（包含xml配置文件，導致部分class文件不能直接混淆）。下面開始說詳細的操作步奏：
1）將web項目的src目錄的java文件打包，只需要選擇java文件即可，其他配置文件什么的都不用選擇，如圖
2）到http://proguard.sourceforge.net/下載proguard，目前我下載并使用的是proguard5.1（注：本人下載頻道也有proguard5.1）。
3）解壓proguard5.1，執行?bin目錄下的proguardgui.bat然后會彈出如下圖所示窗口
4）點擊左邊“input/output”菜單，然后點擊右邊的“Add?input”按鈕，添加需要混淆的jar包，我這里是test.jar,然后點擊“add output”,選擇輸出的路徑和包名。
5）下面開始添加支持庫，這個地方很重要，很多同學剛開始使用這個工具的時候就是這里老是出問題。? ?點擊右邊的“add”。
說明一下，這里最好把你的eclipse里java project里的libraries所有Library的jar包，包含web項目lib下面的包，jdk中jre下面的包和servlet.jar包等copy到一個目錄，然后在這里加入這些jar包。系統默認會帶上rt.jar,這里我們可以先remove掉，然后到jre下面copy所有的包。
6）點擊“shrinking”，設置成如圖所示。
7）點擊“obfuscation”，設置如圖所示
8）點擊“optimization”設置如圖所示
9）點擊information,設置如圖所示，注意選擇jdk版本（Target）
10)?點擊“process”，再點擊“save configuration”，在彈出的對話框中，輸入要保存的配置文件名稱(這里我的是1111111.pro)，最后點擊“保存”.
11)?設置基本完成，關掉proguard窗口，找到剛剛保存的配置文件，開始手動修改部分配置。
以下是我的配置文件，經測試通過，手動修改的部分為紅色字體

12）手動設置完成后保存，然后重新打開progrard，執行 bin目錄下的proguardgui.bat。
???點擊第一個選項“Proguard”，再點擊“Load configuration”，選擇我們剛才保存的“1111111.pro”進行加載。
13）然后點擊Process，然后點擊View configuration查看是否是已經修改過后的配置文件。
14）?確認是最新修改過的配置文件，然后點擊process！開始混淆。。
如下圖，表示混淆成功。。
15）我們可以用jd-gui反編譯工具看看混淆后的效果?？梢钥吹?#xff0c;之前設置不混淆的類都沒有更換類名，而混淆的類都自動更換為a,b,c等類名了。到此，整個java項目混淆就成功了，然后把混淆成功的class文件拷貝到自己的web項目中，替換原先的class文件，然后用tomcat跑項目，發現和正常的class文件運行效果一樣，項目正常運行。
16）說明下配置
參數：??-include {filename}??? 從給定的文件中讀取配置參數?-basedirectory {directoryname}??? 指定基礎目錄為以后相對的檔案名稱?-injars {class_path}??? 指定要處理的應用程序jar,war,ear和目錄?-outjars {class_path}??? 指定處理完后要輸出的jar,war,ear和目錄的名稱?-libraryjars {classpath}??? 指定要處理的應用程序jar,war,ear和目錄所需要的程序庫文件?-dontskipnonpubliclibraryclasses??? 指定不去忽略非公共的庫類。?-dontskipnonpubliclibraryclassmembers??? 指定不去忽略包可見的庫類的成員。?保留選項?-keep {Modifier} {class_specification}??? 保護指定的類文件和類的成員?-keepclassmembers {modifier} {class_specification}??? 保護指定類的成員，如果此類受到保護他們會保護的更好-keepclasseswithmembers {class_specification}??? 保護指定的類和類的成員，但條件是所有指定的類和類成員是要存在。?-keepnames {class_specification}??? 保護指定的類和類的成員的名稱（如果他們不會壓縮步驟中刪除）?-keepclassmembernames {class_specification}??? 保護指定的類的成員的名稱（如果他們不會壓縮步驟中刪除）-keepclasseswithmembernames {class_specification}??? 保護指定的類和類的成員的名稱，如果所有指定的類成員出席（在壓縮步驟之后）?-printseeds {filename}??? 列出類和類的成員-keep選項的清單，標準輸出到給定的文件??壓縮?-dontshrink??? 不壓縮輸入的類文件?-printusage {filename}?-whyareyoukeeping {class_specification}??????優化?-dontoptimize??? 不優化輸入的類文件?-assumenosideeffects {class_specification}??? 優化時假設指定的方法，沒有任何副作用?-allowaccessmodification??? 優化時允許訪問并修改有修飾符的類和類的成員??混淆?-dontobfuscate??? 不混淆輸入的類文件?-printmapping {filename}?-applymapping {filename}??? 重用映射增加混淆?-obfuscationdictionary {filename}??? 使用給定文件中的關鍵字作為要混淆方法的名稱?-overloadaggressively??? 混淆時應用侵入式重載?-useuniqueclassmembernames??? 確定統一的混淆類的成員名稱來增加混淆?-flattenpackagehierarchy {package_name}??? 重新包裝所有重命名的包并放在給定的單一包中?-repackageclass {package_name}??? 重新包裝所有重命名的類文件中放在給定的單一包中?-dontusemixedcaseclassnames??? 混淆時不會產生形形色色的類名?-keepattributes {attribute_name,...}??? 保護給定的可選屬性，例如LineNumberTable, LocalVariableTable, SourceFile, Deprecated, Synthetic, Signature, and InnerClasses.?-renamesourcefileattribute {string}??? 設置源文件中給定的字符串常量
