springboot打包依赖包和配置文件分离

前言：springboot项目打包使用spring-boot-maven-plugin插件，默认会将依赖包和配置文件统统打进可执行jar文件中，使得jar文件太臃肿，则正式环境修改配置文件较麻烦，因此需要将配置文件和依赖jar包分离。如下：

    ${project.name}
    src/main/java
    
    
        
            src/main/resources
            
                **/*.properties
                **/*.xml
                **/*.yml
            
            false
            
            ${project.build.directory}/${project.name}/config
        
        
            src/main/bin
            ${project.build.directory}/${project.name}/bin
        
        
            
            
                
            
        
    
    
        
        
            org.apache.maven.plugins
            maven-jar-plugin
            
                
                    
                    false
                    
                        
                        true
                        
                        lib/
                        com.epri.dcloud.data.LoopcloseriskanalyzeApplication
                    
                    
                    
                        config/
                    
                
                
                    **/*.properties
                    **/*.sh
                    **/*.xml
                    **/*.yml
                
                ${project.build.directory}/${project.name}
            
        
        
        
            org.apache.maven.plugins
            maven-dependency-plugin
            
                
                    copy
                    package
                    
                        copy-dependencies
                    
                    
                        
                            ${project.build.directory}/${project.name}/lib
                        
                        false
                        false
                        runtime
                    
                
            
        
        
        
            org.apache.maven.plugins
            maven-surefire-plugin
            
                true
