如何在Spring Boot应用程序中读取我的META-INF / MANIFEST.MF文件？ [英] How to read my META-INF/MANIFEST.MF file in a Spring Boot app?

问题描述

我正在尝试从我的Spring Boot网络应用程序（包含在jar文件中）中读取我的META-INF / MANIFEST.MF文件。

I'm trying to read my META-INF/MANIFEST.MF file from my Spring Boot web app (contained in a jar file).

我是尝试以下代码：

        InputStream is = getClass().getResourceAsStream("/META-INF/MANIFEST.MF");

        Properties prop = new Properties();
        prop.load( is );

但是显然Spring Boot中有一些东西可以加载不同的manifest.mf（和不是我自己位于META-INF文件夹中。）

But apparently there is something behind the scenes in Spring Boot that a different manifest.mf is loaded (and not my own located in META-INF folder).

有谁知道如何在Spring Boot应用程序中阅读我的清单应用程序？

Does anyone know how I can read my manifest app in my Spring Boot app?

更新：经过一番研究后，我注意到使用通常的方式读取manifest.mf文件，在Spring Boot应用程序中这是正在访问的Jar

UPDATE: After some research I noticed that using the usual way to read a manifest.mf file, in a Spring Boot application this is the Jar that is being accessed

org.springframework.boot.loader.jar.JarFile

推荐答案

我使用 java.lang.Package 从清单中读取spring boot中的 Implementation-Version 属性。

I use java.lang.Package to read the Implementation-Version attribute in spring boot from the manifest.

String version = Application.class.getPackage().getImplementationVersion();

应配置 Implementation-Version 属性在 build.gradle

jar {
    baseName = "my-app"
    version =  "0.0.1"
    manifest {
        attributes("Implementation-Version": version)
    }
}
