在春季启动中使用可执行jar命令时出现资源FileNotFoundException [英] Resource FileNotFoundException when using executable jar command with spring boot

问题描述

要在我的春季启动应用中启用 https ，我执行了以下操作.

To enable https in my spring-boot app I did the following.

@Bean
@Inject
public EmbeddedServletContainerCustomizer containerCustomizer() throws FileNotFoundException
{
    final String absoluteKeystoreFile = ZenoTuringServiceApp.class.getClassLoader().getResource("test.jks").getFile();

    return (ConfigurableEmbeddedServletContainer factory) -> {
        TomcatEmbeddedServletContainerFactory containerFactory = (TomcatEmbeddedServletContainerFactory) factory;
        containerFactory.addConnectorCustomizers((TomcatConnectorCustomizer) (Connector connector) -> {
            connector.setSecure(true);
            connector.setScheme("https");
            connector.setAttribute("keystoreFile", absoluteKeystoreFile);
            connector.setAttribute("keystorePass", "test");
            connector.setAttribute("keystoreType", "JKS");
            connector.setAttribute("clientAuth", "false");
            connector.setAttribute("sslProtocol", "TLS");
            connector.setAttribute("SSLEnabled", true);
        });
    };
}

如果我使用 mvn spring-boot:run 运行它，它将按预期运行.

If I run it using mvn spring-boot:run it works as expected.

但是当我将可执行jar与java -jar target/xxx-xxx-service-0.1.17-SNAPSHOT.jar一起使用时，我得到FileNotFoundException.

But when I run using the executable jar with java -jar target/xxx-xxx-service-0.1.17-SNAPSHOT.jar I get the FileNotFoundException.

推荐答案

上面的注释和此代码对我有所帮助.

The comments above and this code helped me..

// support loading the JKS from the classpath (to get around Tomcat limitation)
private static File getTuringKeyStoreFile() throws IOException {
    ClassPathResource resource = new ClassPathResource("test.jks");

    // Tomcat won't allow reading File from classpath so read as InputStream into temp File
    File jks = File.createTempFile("ssl_keystore", ".jks");
    InputStream inputStream = resource.getInputStream();
    try {
        FileUtils.copyInputStreamToFile(inputStream, jks);
    } finally {
        IOUtils.closeQuietly(inputStream);
    }

    return jks;
}
