Question

问题已编辑。我正在尝试在JNLP中运行spring boot应用程序，但在解决所有安全问题后，我仍然遇到此错误。它发生在启动时的春季启动初始化期间。它显然与弹簧启动生命周期和保护域有关，但我真的不知道如何解决它。当使用java -jar Test.jar作为独立应用程序运行时，JAR运行完美。

来自Java WebStart控制台的异常：

   Unable to determine code source archive from \\localhost:8080\jnlp\Test.jar
org.springframework.boot.loader.Launcher.createArchive(Launcher.java:151)
        at org.springframework.boot.loader.PropertiesLauncher.<init>(PropertiesLauncher.java:149)
        at org.springframework.boot.loader.PropertiesLauncher.main(PropertiesLauncher.java:607)

        at com.sun.javaws.Launcher.run(Unknown Source)
        at java.lang.Thread.run(Unknown Source)

Launcher.java（spring-boot-tools）中发生异常：

protected final Archive createArchive() throws Exception {
        ProtectionDomain protectionDomain = getClass().getProtectionDomain();
        CodeSource codeSource = protectionDomain.getCodeSource();
        URI location = (codeSource == null ? null : codeSource.getLocation().toURI());
        String path = (location == null ? null : location.getSchemeSpecificPart());
        if (path == null) {
            throw new IllegalStateException("Unable to determine code source archive");
        }
        File root = new File(path);
        if (!root.exists()) {
            throw new IllegalStateException(
                    "Unable to determine code source archive from " + root);
        }
        return (root.isDirectory() ? new ExplodedArchive(root)
                : new JarFileArchive(root));
    }

Spring引导无法获取执行的spring boot jar的绝对路径 - 它只传递一种格式的URI，在我的案例中是\ localhost：8080 \ jnlp \ Test.jar，通常是location指向文件的绝对URI。因此，Spring Boot无法在Java WebStart中初始化。

我的JNLP：

<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="1.0+" codebase="http://localhost:8080/" href="Test.jnlp">
    <information>

        <vendor>TEST</vendor>
        <homepage href="http://localhost:8080/" />
        <description>Testing Testing</description>
    </information>
    <update check="timeout" policy="always"/>
    <security>
        <all-permissions/>
    </security>
    <resources>
        <j2se version="1.8+" />
        <jar href="/jnlp/Test.jar" />
    </resources>
    <application-desc main-class="org.springframework.boot.loader.PropertiesLauncher" />
</jnlp>

如何在不修复spring boot library的情况下在Launcher.java中推送绝对文件路径的任何提示？

更新：我看到这个问题不容易解决... Spring启动根本不支持从非文件（或非servlet）位置运行，因为它适用于自定义类加载器。另外，path变量应该与执行的jar相同，因此无法将引导指向新下载的文件（实际上是相同的jar）。：（

The solution was to add the MODULE layout for the plugin in the pom.xml file

<plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <layout>MODULE</layout>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
