springboot代码混淆

        主要就是在pom的build里添加proguard插件，如下（注意，我建议用6.0.2的proguard版本，不然混淆springboot2.X的时候会报错Can't process class [META-INF/versions/9/org/apache/logging/log4j/util/ProcessIdUtil.class，因为springboot2.X引用的log4j模块里有jdk9的支持，但是proguard6之前不支持）：

                        -keepattributes Exceptions,InnerClasses,Signature,Deprecated,
                            SourceFile,LineNumberTable,*Annotation*,EnclosingMethod
                        
                        -keepnames interface **
                        
                        -keepparameternames
                        
                        -keep class !cn.com.geovis.monitor.controller.LoginController { *; }
                        
                        
                        -keep interface * extends * { *; }
                       
                        -keepclassmembers class * {
                                @org.springframework.beans.factory.annotation.Autowired *;
                                @org.springframework.beans.factory.annotation.Value *;
                                @org.springframework.web.bind.annotation.PostMapping *;
                                @org.springframework.web.bind.annotation.DeleteMapping *;
                            }
                        
                    

                    
                    
                    
                    	${java.home}/lib/rt.jar
                    	${java.home}/lib/jce.jar
                    
	            
                
                    
                        net.sf.proguard
                        proguard-base
                        6.0.2
                        runtime
                    
                
            
			
                org.springframework.boot
                spring-boot-maven-plugin
                
                    
                    	
                    		cn.com.geovis.monitor.ServiceManageApp
                		
                        none
                        
                            repackage
                        
                    
                
            
    
        
    

        然后pom同级目录添加proguard.cfg文件，内容如下：

-target 1.8
-keep class cm.com.geovis.monitor.utils.** {*;}  
-dontshrink
-dontoptimize
-useuniqueclassmembernames
-adaptclassstrings
-ignorewarnings
-dontusemixedcaseclassnames
-keepattributes Exceptions,InnerClasses,Signature,Deprecated,SourceFile,LineNumberTable,*Annotation*,EnclosingMethod

        然后mvn clean install -DskipTest，大功告成，可以看到LoginController类已经被混淆了。
