篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Proguard 混淆的一些经验教训！！！相关的知识，希望对你有一定的参考价值。
混淆工具 proguard 前后接触一段时间了，差不多了是明白了，不过遇到很多坑，差点被跳不出来坑了！真的难学啊！ 真是是太难了；
教训1 ServerKeyStore 是kotlin类，不能 进行普通的混淆。
2020-02-29 01:28:18,786 [ERROR] PCStarter:167 - Unable to start server. biz.lk.pcng.server.ServerKeyStore$a.invoke()Ljava/lang/Object; [main] java.lang.AbstractMethodError: ...server.ServerKeyStore$a.invoke()Ljava/lang/Object; at kotlin.SynchronizedLazyImpl.getValue(LazyJVM.kt:74) at ...server.ServerKeyStore.getCertAlias(ServerKeyStore.kt) at ...server.web.Jetty.c(Jetty.java) at ...server.web.Jetty.c(Jetty.java) at ...server.web.Jetty.a(Jetty.java) at ...server.web.Jetty.a(Jetty.java) at ...server.web.EmbeddedServer.start(EmbeddedServer.java) at com.lk.PCStarter.startWebServer(PCStarter.java:271) at com.lk.PCStarter.start(PCStarter.java:158) at com.lk.PCStarter.start000(PCStarter.java:115) at com.lk.PCStarter.main(PCStarter.java:67) Disconnected from the target VM, address: ‘127.0.0.1:44519‘, transport: ‘socket‘
原因分析：反编译可以看到ServerKeyStore 的很多信息丢失了，被变成了java 类，但是人家本来就不是java类； 而且kotlin 的一下特有的注解 也不见了；
解决方案：需要保留kotlin 特性
教训2 匿名内部类，被重命名了为a、b、c之类，方法的实现、继承全部失效，而且不抛错误！

原因分析：因为它不是public 类，本来需要一个， 结果找不到，因为混淆之后，某些package 没有被扫描到！ 混淆之后 原来继承jetty框架的类， 因为是内部类，被重命名了为a、b、c之类的导致 相当于没有继承，从而没有执行，从而导致了 严重问题！
解决方案：需要保留某些内部匿名类、非public内等
教训3 private 方法，混淆之后被重命名，hibernate 反射访问出错：

原因分析：本来需要一个 setGroupLinks, 结果因为 setGroupLinks 是 private 方法，混淆之后被重命名.. ———— 没想到 hibernate需要对 private 方法进行反射， 实在没想到。
解决方案：需要保留persistent层 hibernate用到的一些 domain 类 的private 属性

原因分析：注意看，错误是 ： Cannot convert value of type ‘...service.impl.AccountManagerImpl$$..‘ to required type ‘...persistence.UserDAO, 简直不可思议， 为什么会进行 AccountManagerImpl 和 UserDAO 的转换？ 猜测是因为 userManager 的构造器有多个参数， 混淆之后 参数名字丢失， 无法 根据applicationContext-service.xml进行名字的设定，所以出现了这等奇怪问题；
解决方案： UserManager 及 UserManagerImpl 等service类不进行任何的混淆.. 暂时只能这样。
教训4 需一个类， 结果却有多个：
biz.papercut.pcng.server.config.CommonConfig#propertyConfigurer
@ImportResource( locations = {"classpath:/applicationContext-main.xml", "classpath:/biz/papercut/pcng/persistence/hibernate/applicationContext-hibernate.xml", "classpath:/biz/papercut/pcng/service/applicationContext-service.xml", "classpath:/biz/papercut/pcng/webservices/xmlrpc/applicationContext-xmlrpc.xml", "classpath*:/com/papercut/device/web/**/applicationContext-device-web-*.xml"} ) @Configuration public class CommonConfig { public CommonConfig() { } @Bean public ServerConfig bootstrapConfig() { return ServerConfig.getInstance(); } @Bean public Properties bootstrapProperties(ServerConfig serverConfig) { return serverConfig.getAllProperties(); } @Bean public PropertySourcesPlaceholderConfigurer propertyConfigurer(Properties bootstrapProperties) { PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer = new PropertySourcesPlaceholderConfigurer(); propertySourcesPlaceholderConfigurer.setProperties(bootstrapProperties); propertySourcesPlaceholderConfigurer.setIgnoreResourceNotFound(true); propertySourcesPlaceholderConfigurer.setIgnoreUnresolvablePlaceholders(true); return propertySourcesPlaceholderConfigurer; } }
propertyConfigurer 方法需要一个 Properties ， 结果发现有多个：
原因分析：反编译可以看到 propertyConfigurer 方法的参数名字已经丢失了，不知道为什么， 本来应该是 bootstrapProperties， 结果却.. 猜测是 不能通过name进行自动注入，于是只能通过type，但是可选的 type有多个， 故出现错误..
解决方案： 保留必要的方法签名， 包括名字、参数

注意
dontwarn不能出现多次， 否则以后者为准 ，忽视前面的， Proguard 这个配置 非常蛋疼， 一不小心结果面目全非。
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘...service.ConfigManager‘ available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}
以上是关于Proguard 混淆的一些经验教训！！！的主要内容，如果未能解决你的问题，请参考以下文章
Android Studio：proguard 行号错误，没有完全混淆
