java - REST 应用程序在 Eclipse 中运行，但不是作为可执行 jar。 NoClassDefFound错误: javax/xml/bind/annotation/XmlElement

Question

我已经使用 Jersey 注释编写了 REST 资源。为了在 Spring Boot 中实现这一点，我添加了 JerseyConfiguration 类:

@Configuration
@ApplicationPath("/api")
public class JerseyConfiguration extends ResourceConfig {
    public JerseyConfiguration() {  }

    @PostConstruct
    public void setUp() {
        register(AdminController.class);
        register(AdminResource.class);
        register(GenericExceptionMapper.class);
    }
}

在 Eclipse 中运行应用程序时效果很好。当我创建并运行 jar 文件时，出现以下错误:

12:45:15.311 [main] ERROR o.s.boot.SpringApplication : Application startup failed org.springframework.context.ApplicationContextException: Unable to start embedded container;
nested exception is java.lang.RuntimeException: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.jersey.JerseyAutoConfiguration': Bean instantiation via constructor failed;

nested exception is java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlElement

谁能告诉我为什么会发生这种情况？据我所知，javax/xml/bind/annotation 是 Java 8 rt.jar

的一部分

我正在使用 Spring Boot 1.5.9.RELEASE，Java 8

我以为我使用 Java 8 SDK 启动了 jar，但它实际上是 Java 9 JRE。因此，使用 Java 8 SDK java.exe 启动 jar 时不会出现问题。使用Java 8 SDK启动jar已经解决了这个问题。
