春季啓動Windows 10系統屬性「file.encoding的」

Question

我想用下面的命令來啓動春季啓動超級罐子：

java -jar api-0.0.1.jar -Dfile.encoding=UTF-8 

，但它失敗了以下錯誤：

07:52:54.573 [main] INFO com.example.domain.api.Application - Starting application... 
2017-08-01 07:52:55.071 ERROR 5792 --- [   main] o.s.b.c.FileEncodingApplicationListener : System property 'file.encoding' is currently '

而且，我在我的Maven的pom.xml以下屬性：

<properties> 
    <java.source.version>1.8</java.source.version> 
    <java.target.version>1.8</java.target.version> 
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 
    <file.encoding>UTF-8</file.encoding> 
</properties> 

我在做什麼錯誤以及如何正確地推出THI應用程序？

Answer 1

Java SE 6支持的兩種編碼集。新java.nio API使用的規範名在很多情況下與java.io和java.lang API中使用的不同。

• ，如果你是java.nio中的API使用規範名稱，你需要使用：UTF-8
• ，如果你是java.io和的java.lang API使用規範名稱，您需要使用： UTF8

所以使用-Dfile.encoding=UTF-8或-Dfile.encoding=UTF8
