我运行mvn clean install
,target/classes下的bootstrap.properties设置了值

而src/main/liberty/config下的同一个文件仍然具有占位符
此外,当我试图在应用程序中读取这些属性时,它们是null

我遗漏了什么或做错了什么?Francesco,首先检查您正在注入config的类是否作为CDIBean正确启用(使用bean定义注释或存在有效的beans.xml)
第二,您从哪里调用
initITServiceUIDs
?如果您从构造函数调用它,那么字段还没有被注入。Francesco,首先检查您正在注入config的类是否作为CDIBean正确启用(带有bean定义注释或存在有效的beans.xml)

。有关更多详细信息,请参阅。您可以定义POM属性:propValue
,这将导致在boostrap.properties文件中生成属性:ADServiceUID=propValue
