Spring本机运行时错误:可访问不支持的方法java.lang.Class.isSealed()

Question

我正在尝试执行由Spring原住民和Spring创建的本地映像。执行在/target目录中生成的应用程序会给出以下错误：

我在我的pom.xml中使用以下依赖项：

       <dependency>
            <groupId>org.springframework.experimental</groupId>
            <artifactId>spring-native</artifactId>
            <version>0.12.0</version>

这些插件：

                </executions>
            </plugin>

这些资料是用来建立本地形象的：

                        </executions>

                        <configuration>
                            <classifier>exec</classifier>
                        </configuration>
                    </plugin>
                </plugins>
            </build>
        </profile>

为了构建映像，我使用以下命令行：mvn package -Pnative或mvn package spring-boot:build-image；然后，结果出现在/target目录中，我使用./target/myApp来运行它。

以下是java --version的结果：

openjdk 17.0.3 2022-04-19
OpenJDK Runtime Environment GraalVM CE 21.3.2 (build 17.0.3+7-jvmci-21.3-b14)
OpenJDK 64-Bit Server VM GraalVM CE 21.3.2 (build 17.0.3+7-jvmci-21.3-b14, mixed mode, sharing)

我在github上找到了这个问题，它看起来与我的非常相似，如果不是完全相同的话。票已经关了，但我不明白决议。

该错误似乎与与环境相关的概要文件(dev、prod、test .)有关。Spring本地文档的一部分致力于这方面的工作。为了解决这个错误，我在application.yml配置文件中填写了一个配置文件。概要文件在运行时正确加载，但错误相同。

这个错误不是来自jdk和Spring库之间的兼容性问题吗？但是，从jdk 17开始，在javadoc中就出现了该方法。

提前感谢

Answer 1

从您链接的github问题中可以看出，解决方案是在GraalVM中的密封类上添加反射支持。

这是通过跟随拉请求合并到主服务器上的。

在GraalVM发行说明中，我们可以看到，这使得它进入了来自22.0.0版本和更高版本的版本。

22.0.0 (2021-01-18)

这个日期似乎不对，可能是2022-01-18

在JDK 17: Class.isSealed()和Class.getPermittedSubclasses()上增加了对密封类反射内省的支持。

您当前的JDK使用的是GraalVM 21.3.2，因此还不包含此修复。解决方案是找到一个具有22.x或更高版本GraalVM的JDK构建。
