如何告诉proguard保持枚举常量和字段 [英] How to tell proguard to keep enum constants and fields
问题描述
我尝试混淆使用spring,jaxb并依赖于注释和反射的Web应用程序。
我在互联网上应用了许多食谱来保存一些类,属性,注释和枚举。
但是枚举仍有问题。我能够保存枚举常量应用
如果我尝试获取
我的proguard配置现在看起来像(删除一些库列表和kipp特定的类,关于proguard抱怨的字段和方法):
-injars core-3.15.rc5.6.jar
-outjars cor e-3.15.rc5.6.proguard.jar
-libraryjars< java.home> /lib/rt.jar
-libraryjars ...#列出的其他库为了简洁而剥离
-printmapping core-3.15.rc5.6.proguard.map
-keep public class ru.rlh.egais.portal.backend.controller。休息。**
-keep public class ru.rlh.egais.portal.backend.integration.soap.service。**

}
那么,我的问题是如何完全保持公共枚举不被混淆?在这两种情况下 - 使用其常量( class .getEnumConstants())和字段( class.getFields())。
感谢 http://sourceforge.net/p/proguard/discussion/182455/thread/1c28f199/ 我找到了解决方案对于我的问题(必须添加<fields> ):
-keepclassmembers class * extends java.lang.Enum {
< fields> ;;
public static ** [] values();
public static ** valueOf(java.lang.String);
}
I've try obfuscate our web application which use spring, jaxb and relies on annotations, and reflection heavily. I apply many recipes found in internet to keep some classes, attributes, annotations and enumerations. But with enumerations still have problem. I've able preserve enum constants apply configuration from http://proguard.sourceforge.net/manual/examples.html#enumerations:
-keepclassmembers,allowoptimization enum * {
public static **[] values();
public static ** valueOf(java.lang.String);
}
At first glance it looks like working solution and constant preserved, so (Class.getEnumConstants()) return correct list of values. But I got NoSuchFieldException when I try retrieve field by any of that by name.
Problem come from jaxb reflection navigator, please look at code:
public Field[] getEnumConstants(Class clazz) {
try {
Object[] values = clazz.getEnumConstants();
Field[] fields = new Field[values.length];
for (int i = 0; i < values.length; i++) {
fields[i] = clazz.getField(((Enum) values[i]).name());
}
return fields;
} catch (NoSuchFieldException e) {
// impossible
throw new NoSuchFieldError(e.getMessage());
}
}
I fall exactly into "impossible" branch. I think it will be easy understandable to look at debug session screenshot (there also listed constants):
And if I try obtain fields, they are listed obfuscated as a, b, c, d, e, f:
My proguard configuration now look like (strip out some library listing and kipp particular classes, fields and methods about proguard complain):
-injars core-3.15.rc5.6.jar
-outjars core-3.15.rc5.6.proguard.jar
-libraryjars <java.home>/lib/rt.jar
-libraryjars ... # Other libs listed, strip out for shortness
-printmapping core-3.15.rc5.6.proguard.map
-keep public class ru.rlh.egais.portal.backend.controller.rest.**
-keep public class ru.rlh.egais.portal.backend.integration.soap.service.**

@org.aspectj.lang.annotation.AfterReturning *;
@org.aspectj.lang.annotation.Pointcut *;
@org.aspectj.lang.annotation.AfterThrowing *;
@org.aspectj.lang.annotation.Around *;
}
-keepclassmembers enum * {
public static **[] values();
public static ** valueOf(java.lang.String);
}
So, my question how I could fully keep public enums from obfuscation? In both cases - use its constants (class.getEnumConstants()) and fields (class.getFields()).
Thanks to http://sourceforge.net/p/proguard/discussion/182455/thread/1c28f199/ I found solution for my question (<fields> must be added):
-keepclassmembers class * extends java.lang.Enum {
<fields>;
public static **[] values();
public static ** valueOf(java.lang.String);
}
