将proguard与图书馆一起使用@service bean，该豆子应该自动

Question

我有一个图书馆公共。

<plugin>
    <groupId>com.pyx4me</groupId>
    <artifactId>proguard-maven-plugin</artifactId>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>proguard</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <obfuscate>true</obfuscate>
        <options>
            <option>-dontoptimize</option>
            <option>-renamesourcefileattribute SourceFile</option>
            <option>-keepattributes Exceptions,InnerClasses,Signature,Deprecated,SourceFile,LineNumberTable,*Annotation*,EnclosingMethod</option>
            <option>-keep public class * { public protected *;}</option>
            <option>-keepclassmembernames class * {java.lang.Class class$(java.lang.String); java.lang.Class class$(java.lang.String, boolean);}</option>
            <option>-keepclassmembernames class * {com.common.license.LicenseSessionStore licenseSessionStore; com.common.license.LicenseStore licenseStore;}</option>
            <option>-keepclassmembers enum * {public static **[] values(); public static ** valueOf(java.lang.String);}</option>
            <option>-keepclassmembers class * implements java.io.Serializable { static final long serialVersionUID; private static final java.io.ObjectStreamField[] serialPersistentFields; private void writeObject(java.io.ObjectOutputStream); private void readObject(java.io.ObjectInputStream); java.lang.Object writeReplace(); java.lang.Object readResolve();}</option>
        </options>
        <libs>
            <lib>${java.home}/lib/rt.jar</lib>
            <lib>${java.home}/lib/jsse.jar</lib>
        </libs>
        <addMavenDescriptor>false</addMavenDescriptor>
    </configuration>
</plugin>

该库有一个带有@Service的春豆：

@Service
public class LicenseServiceImpl implements LicenseService {

    @Autowired(required = false)
    LicenseSessionStore licenseSessionStore;

    @Autowired(required = false)
    LicenseStore licenseStore;

...

}

我在Web服务公司中使用此库。确定性我希望使用许可证的自动服务：

@Component
public class BackgroundTasks {

    @Autowired
    ScheduledExecutorService scheduledExecutorService;

    @Autowired
    LicenseService licenseService;

...

}

因此，公司的确定性依赖于common.license。如果我混淆了普通。 licenseService 不会在 BackgroundTasks. 。我解决此问题的唯一方法是将许可证明确定义为bean：

@Bean(name = "licenseService", autowire = Autowire.BY_NAME)
public LicenseService getLicenseService() {
    if (licenseService == null) {
        licenseService = new LicenseServiceImpl();
    }
    return licenseService;
}

我不需要明确将其声明为这样的豆子 @Service 这足以使 licenseService 在 BackgroundTasks 春季数字工作。但这不是！

Proguard专门为使它不起作用而采取什么行动？我可以做些什么，使其在Proguard的配置中可以使其更加春季友好？

非常感谢埃里克·洛赫特（Eric Lafortune）在这里帮助我指向正确的方向：

这是指定插件和所需选项的工作POM文件添加：

<plugin>
    <groupId>com.pyx4me</groupId>
    <artifactId>proguard-maven-plugin</artifactId>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>proguard</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <obfuscate>true</obfuscate>
        <options>
            <option>-dontoptimize</option>
            <option>-keepdirectories</option>
            <option>-renamesourcefileattribute SourceFile</option>
            <option>-keepattributes Exceptions,InnerClasses,Signature,Deprecated,SourceFile,LineNumberTable,*Annotation*,EnclosingMethod</option>
            <option>-keep public class * { public protected *;}</option>
            <option>-keepclassmembernames class * {java.lang.Class class$(java.lang.String); java.lang.Class class$(java.lang.String, boolean);}</option>
            <option>-keepclassmembernames class * {com.common.license.LicenseService licenseService; com.common.license.LicenseSessionStore licenseSessionStore;}</option>
            <option>-keepclassmembers enum * {public static **[] values(); public static ** valueOf(java.lang.String);}</option>
            <option>-keepclassmembers class * implements java.io.Serializable { static final long serialVersionUID; private static final java.io.ObjectStreamField[] serialPersistentFields; private void writeObject(java.io.ObjectOutputStream); private void readObject(java.io.ObjectInputStream); java.lang.Object writeReplace(); java.lang.Object readResolve();}</option>
            <option>-keep @org.springframework.beans.factory.annotation.Service class *</option>
            <option>-keep @org.springframework.stereotype.Controller class *</option>
            <option>-keepclassmembers class * { @org.springframework.beans.factory.annotation.Autowired *; }</option>
        </options>
        <libs>
            <lib>${java.home}/lib/rt.jar</lib>
            <lib>${java.home}/lib/jsse.jar</lib>
        </libs>
        <addMavenDescriptor>false</addMavenDescriptor>
    </configuration>
</plugin>

笔记！您需要使用Proguard 4.4，这是最新版本的Proguard-Maven-Plugin（2.0.4）使用4.3，因此您需要编辑：

{M2_HOME}\repository\com\pyx4me\proguard-maven-plugin\2.0.4\proguard-maven-plugin-2.0.4.pom 

具有4.4依赖关系（如这样）：

<dependency>
  <groupId>net.sf.proguard</groupId>
  <artifactId>proguard</artifactId>
  <version>4.4</version>
  <scope>runtime</scope>
  <optional>true</optional>
</dependency>

Answer 2

这是切换到Proguard版本4.4版的另一种方法（这可能更好一些）：

<configuration>
  <proguardVersion>4.4</proguardVersion>
  <obfuscate>true</obfuscate>
  <options>
  ... 
  </options>    
  <libs>
    <lib>${java.home}/lib/rt.jar</lib>
    <lib>${java.home}/lib/jsse.jar</lib>
  </libs>
  <addMavenDescriptor>false</addMavenDescriptor>
</configuration>
<dependencies>
  <dependency>
    <groupId>net.sf.proguard</groupId>
    <artifactId>proguard</artifactId>
    <version>4.4</version>
    <scope>runtime</scope>
    <optional>true</optional>
  </dependency>
</dependencies>

我也遇到了同样的问题，并且 - keepdirectories指令帮助我解决了问题。
