运行 java 配置文件位于不同目录中的程序

Question

我是运行一个 java 程序，我的程序在一个 jar 文件中（我创建的可执行 jar）让我们将其命名为 Test.jar 我的程序需要一些属性存在于 config.properties 文件中，我没有包含在 jar 中但将它们保存在名为 conf 的目录中现在我需要将这些配置文件添加到类路径中，以便程序在运行.

时可以具有这些属性

但问题是在我的程序执行期间找不到属性文件，它抛出文件未找到异常。我正在使用 spring 5 并使用注解 @PropertySource({"classpath:config.properties","classpath:application.properties"}) 读取配置所以理想情况下，如果我将配置放在类路径中，它应该读取。

n.b- 我在运行使用 eclipse 的程序中没有问题，我的属性文件位于资源目录

我是运行来自命令行的程序 - java -cp "Test.jar;conf*" com.test.TestMain

我收到文件未找到异常

我的目录结构是 TestCode 目录，里面有 conf 目录和 Test.jar 文件，我来自 TestCode 目录运行

我的 maven 构建结构如下所示，不确定是否与 maven 有关

<build>
<resources>
<resource>
<directory>src/main/resources</directory>
<excludes>
<exclude>**/*.properties</exclude>
<exclude>**/log4j2.xml</exclude>
</excludes>
<filtering>false</filtering>
</resource>
</resources>
<pluginManagement>
<plugins>

<directory>src/main/resources</directory>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
</plugins> 
</pluginManagement>
</build>

我得到的异常是

Answer 1

这是Windows或Linux中的运行吗？因为 -cp 的分隔符是 Windows 的分号和 Unix 的冒号。您是否尝试过 java -Dspring.config.location=/conf/ -jar Test.jar ？这可能更直接，因为您解释的是您的需要。
