为什么在运行 Spring 启动应用程序的 .jar 版本时无法检索此文件？

[英]Why I can't retrieve this file when I run the .jar version of my Spring Boot application?

问题描述

I am working on a Spring Batch application and I am finding some problem retrieving an SSL certificate file (used from RestTemplate ) when I execute the .jar file containing my application.我正在处理 Spring Batch 应用程序，当我执行包含我的应用程序的.jar文件时，我发现在检索 SSL 证书文件（从RestTemplate使用）时出现一些问题。 My application works fine if I run it from STS (Eclipse).如果我从 STS (Eclipse) 运行我的应用程序，它可以正常工作。

I will try to explain in details what I have done and what is the problem.我将尝试详细解释我所做的事情以及问题所在。 Into this folder of my project /src/main/resources/static I have put my certificate file named certificate.pfx :在我的项目/src/main/resources/static的这个文件夹中，我将我的证书文件命名为certificate.pfx ：

在此处输入图像描述

Then into my code I declaring this method returning a RestTemplate bean that retrieve and use this certificate file in order to perform REST call to an external API:然后在我的代码中声明此方法返回一个RestTemplate bean，该 bean 检索并使用此证书文件以执行对外部 API 的 REST 调用：

@Bean
RestTemplate restTemplate() throws KeyManagementException, UnrecoverableKeyException, NoSuchAlgorithmException, KeyStoreException, CertificateException, IOException, URISyntaxException {
    final String password = "password";
    //final String pfxPath = "/home/andrea/Documents/workspace-spring-tool-suite-4-4.11.0.RELEASE/UpdateInfoBatch/target/classes/static/certificate.pfx";
    
    
    URL clientCertRes = getClass().getClassLoader().getResource("static/certificate.pfx");
    
    
    File clientCertFileile = Paths.get(clientCertRes.toURI()).toFile();
    
    
    String clientCertFileileAbsolutePath = clientCertFileile.getAbsolutePath();
    
    System.out.println("clientCertFileileAbsolutePath: " + clientCertFileileAbsolutePath);  
    
    HttpComponentsClientHttpRequestFactory httpComponentsClientHttpRequestFactory = getHttpComponentsClientHttpRequestFactory(clientCertFileileAbsolutePath,password);
    
    RestTemplate restTemplate = new RestTemplate(httpComponentsClientHttpRequestFactory);
    
    return restTemplate;
    
}

If I execute my code from STS\Eclipse it works fine: I have no exception and the call to my external API correctly uses the needed certificate.如果我从 STS\Eclipse 执行我的代码，它工作正常：我没有例外，对我的外部 API 的调用正确使用了所需的证书。

The problem is that when I try to perform my application executing the compiled .jar file version.问题是，当我尝试执行我的应用程序时，会执行已编译的.jar文件版本。 Infact if I execute:事实上，如果我执行：

java -jar UpdateInfoBatch-0.0.1-SNAPSHOT.jar

I am obtaining the following exception starting the application context:我在启动应用程序上下文时获得以下异常：

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

As you can see in the previous stacktrace the cause of this exception is this one:正如您在前面的堆栈跟踪中看到的，此异常的原因是：

Caused by: java.nio.file.FileSystemNotFoundException: null

and I am pretty sure that it should be related to these lines of code where I retrieve the certificate file:而且我很确定它应该与我检索证书文件的这些代码行相关：

URL clientCertRes = getClass().getClassLoader().getResource("static/certificate.pfx");
File clientCertFileile = Paths.get(clientCertRes.toURI()).toFile();
String clientCertFileileAbsolutePath = clientCertFileile.getAbsolutePath();

I am pretty sure because I tried to delete all the lines related to obtain certificate file and I simply returned a classic RestTemplate object:我很确定，因为我试图删除所有与获取证书文件相关的行，我只是返回了一个经典的 RestTemplate object：

RestTemplate restTemplate = new RestTemplate();

doing in this way I obtain no more the previous exception (but instead I obtain the expected SSL exception because to perform my call I need this certificate).这样做我不再获得以前的异常（而是我获得了预期的 SSL 异常，因为要执行我的调用我需要这个证书）。

So...what is wrong?那么……怎么了？ what am I missing?我错过了什么？ How can I try to fix this issue?我该如何尝试解决这个问题？

What could be a good solution?什么是好的解决方案？

  1. To embed the certificate directly into the .jar file?要将证书直接嵌入到.jar文件中？ (in this case I will have an all in one solution) （在这种情况下，我将拥有一个一体化的解决方案）

  2. To point to a specific directory of my file system where I will put my certificate?要指向我的文件系统的特定目录，我将在其中放置我的证书？ (maybe it could be better because if in the future the certificate will change I can simply replace it into the file system avoiding to recompile and redeploy my application) （也许它会更好，因为如果将来证书会改变，我可以简单地将它替换到文件系统中，避免重新编译和重新部署我的应用程序）

What do you think about?你有什么想法？

Code in this answer is a guess because I do not know what is inside the getHttpComponentsClientHttpRequestFactory :).这个答案中的代码是一个猜测，因为我不知道getHttpComponentsClientHttpRequestFactory里面有什么:)。 But I think, you can solve the problem as follows:但我认为，您可以按以下方式解决问题：

  1. Change the way you supply certificate from plain File to URL将您提供证书的方式从普通File更改为URL
  2. Use ClassPathResource to get the certificate's URL使用ClassPathResource获取证书的URL

1. Supply certificate using URL 1.提供证书使用URL

I guess you're using custom SSLContext created using the SSLContexts.custom() returned builder, something similar to:我猜您正在使用使用SSLContexts.custom()返回的构建器创建的自定义SSLContext ，类似于：

SSLContexts.custom()
        .loadTrustMaterial(new File("/tmp/fred.zip"), "apples".toCharArray())
        .build();

You can use the overload accepting URL instead:您可以改用接受URL的重载：

SSLContexts.custom()
        .loadTrustMaterial(new URL("...."), "apples".toCharArray())
        .build();

See also this answer另请参阅此答案

2. Use ClassPathResource to obtain URL 2.使用ClassPathResource获取URL

For example:例如：

ClassPathResource resource = new ClassPathResource("/fred.pfx", SpringBootResourcesApplication.class);
URL url = resource.getURL();
  • fred.pfx is the file I'm loading. fred.pfx是我正在加载的文件。 It is placed directly in resources directory直接放在resources目录下
  • SpringBootResourcesApplication.class is the class that loads the file SpringBootResourcesApplication.class就是加载文件的class

This will work in IDE and in jar file这将在 IDE 和 jar 文件中工作

Wiring everything together将所有东西连接在一起

public class SpringBootResourcesApplication {
    public static void main(String[] args) throws Exception {
        ClassPathResource resource = new ClassPathResource("/fred.pfx", SpringBootResourcesApplication.class);
        URL url = resource.getURL();

        System.out.println(url);

        SSLContext sslContext = SSLContexts.custom()
                .loadTrustMaterial(url, "apples".toCharArray())
                .build();
        System.out.println(sslContext);
    }
}
  • The output from IDE:来自 IDE 的 output：
     file:/home/caco3/IdeaProjects/spring-boot-resources/target/classes/fred.pfx javax.net.ssl.SSLContext@217ed35e
  • From jar:来自 jar：
     jar:file:/home/caco3/IdeaProjects/spring-boot-resources/target/spring-boot-resources-0.0.1-SNAPSHOT.jar./BOOT-INF/classes./fred.pfx javax.net.ssl.SSLContext@3444d69d

Why java.nio.file.FileSystemNotFoundException thrown为什么抛出java.nio.file.FileSystemNotFoundException

Path.get does not always succeed. Path.get并不总是成功。 When you get a URL for the Path using code similar to:当您使用类似于以下代码的Path获得URL时：

URL resource = SpringBootResourcesApplication.class.getClassLoader().getResource("application.properties");

The result can be different, for example:结果可能不同，例如：

  • From IDE in my case it is:在我的例子中，来自 IDE 是：
     file:/home/caco3/IdeaProjects/spring-boot-resources/target/classes/application.properties
  • From jar :来自jar ：
     jar:file:/home/caco3/IdeaProjects/spring-boot-resources/target/spring-boot-resources-0.0.1-SNAPSHOT.jar./BOOT-INF/classes!/application.properties

These URI s are handled differently:这些URI的处理方式不同：

  • The file:/... URI can be successfully converted to a Path The file:/... URI可以成功转换为Path
  • But the jar:file:/... cannot: it requires an explicit FileSystem to be created但是jar:file:/...不能：它需要创建一个明确的FileSystem系统

That's why the exception was thrown这就是抛出异常的原因
