spring boot静态资源路径配置

• 通过yml方式进行定义
  这里的需求是定义服务器加载的图片路径，配置项为
  resource.path.prefix: D:/share/data/space，正确配置如下：

spring:
  mvc:
    static-path-pattern: /**
  resources:
    static-locations: classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/,classpath:/public/,file:${resource.path.prefix}
#The directory of adc resource located
resource.path.prefix: D:/share/data/space

这里遇到的问题是，是使用 STS，自动添加相应配置项，带有“-”，导致配置多个路径的时候，配置不生效

spring:
  mvc:
    static-path-pattern: /**
  resources:
    static-locations:
    - classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/,classpath:/public/,file:${adc.resource.path.prefix}
#The directory of adc resource located
adc.resource.path.prefix: D:/share/data/adcspace

但是单独配置，如下，是可以读取到图片的，还需要进一步了解机制

spring:
  mvc:
    static-path-pattern: /**
  resources:
    static-locations:
    - file:${adc.resource.path.prefix}
#The directory of adc resource located
adc.resource.path.prefix: D:/share/data/adcspace
