spring boot2X代码混淆

为了防止代码很容易被反编译而造成泄露，所以打包时进行代码混淆

使用 proguard-maven-plugin插件

<build>
        <finalName>${artifactId}</finalName>
    <plugins>
            <plugin>
                <groupId>com.github.wvengen</groupId>
                <artifactId>proguard-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals><goal>proguard</goal></goals>
                    </execution>
                </executions>
                <configuration>
                    <proguardVersion>6.0.3</proguardVersion>
                    <injar>${project.build.finalName}.jar</injar>
                    <outjar>${project.build.finalName}.jar</outjar>
                    <obfuscate>true</obfuscate>
                    <proguardInclude>${basedir}/proguard.conf</proguardInclude>
                    <libs>
                        <lib>${java.home}/lib/rt.jar</lib>
                        <lib>${java.home}/lib/jce.jar</lib>
                    </libs>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>net.sf.proguard</groupId>
                        <artifactId>proguard-base</artifactId>
                        <version>6.0.3</version>
                    </dependency>
                </dependencies>
            </plugin>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                        <configuration>
                            <mainClass>com.abc.xyz.BWMApiApplication</mainClass>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

    </plugins>

</build>

proguard的阶段为package

springboot打包在repackage阶段

proguard.conf

-target 1.8
-dontshrink
-dontoptimize
-adaptclassstrings
-ignorewarnings
-keepattributes Exceptions,InnerClasses,Signature,Deprecated,SourceFile,LineNumberTable,*Annotation*,EnclosingMethod
-keepnames interface **
-keepparameternames
-keep class com.abc.xyz.BWMApiApplication { *; }
-keep class com.abc.xyz.configure.** { *; }
-keep class com.abc.xyz.core.** { *; }
-keep class com.abc.xyz.controller.** { *; }
-keep class com.abc.xyz.model.** { *; }
-keep interface * extends * { *; }
-keepclassmembers class * {
      @org.springframework.beans.factory.annotation.Autowired *;
      @org.springframework.beans.factory.annotation.Value *;
  }

proguard混淆不能指定混淆的类名在basePackages下面类名混淆后唯一，不同包名经常有a.class，b.class,c.class之类重复的类名

spring容器初始化bean的时候会报错

修改启动类

package com.xyz.abc;

import org.springframework.beans.factory.config.BeanDefinition;
import org.springframework.beans.factory.support.BeanDefinitionRegistry;
import org.springframework.beans.factory.support.BeanNameGenerator;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;

@SpringBootApplication
public class BWMApiApplication {

    public static class CustomGenerator implements BeanNameGenerator {

        @Override
        public String generateBeanName(BeanDefinition definition, BeanDefinitionRegistry registry) {
            return definition.getBeanClassName();
        }
    }

    public static void main(String[] args) {
        new SpringApplicationBuilder(BWMApiApplication.class)
                .beanNameGenerator(new CustomGenerator())
                .run(args);
    }
}

如果有报错可以手动执行打包命令

mvn clean package -DskipTests=true -P obfuscation
