依赖配置：

    com.alibaba
    fastjson

build配置：

父POM中：

    ${project.artifactId}
    
        
            ${basedir}/src/main/java
            
                **/*.xml
                **/*.properties
            
        
        
            ${basedir}/src/main/resources
        
    
    
        
            
            
                org.apache.maven.plugins
                maven-resources-plugin
                2.7
                
                    UTF-8
                
            
            
            
                org.apache.maven.plugins
                maven-compiler-plugin
                3.5.1
                
                    1.8
                    1.8
                    UTF-8
                
            
        
    

子POM中：

    
        
            ${basedir}/src/main/java
            
                **/*.xml
                **/*.properties
            
        
        
            ${basedir}/src/main/resources
        
    
    
        
            org.apache.maven.plugins
            maven-dependency-plugin
            3.0.2
            
                
                    package
                    
                        copy-dependencies
                    
                
            
            
                system
                ${project.build.directory}/${project.build.finalName}/WEB-INF/lib
            
        
    

子POM中的插件才是解决的关键。
