Jetty（9.4.12）：无法启动上下文o.e.j.w.WebAppContext@2af004b webapp /，不可用

时间：2018-11-05 22:31:07

标签： java jetty jetty-9 java-11

我正在使用码头（9.4.12）在macOS（Java 11）上投放我的Web应用程序。

尽管码头已经启动，但该服务仍然不可用。我和往常一样使用了相同的War文件，但是唯一的区别是，我已经将Java从版本10更新到了版本11。针对此问题的任何可能的修复程序？

错误

答案 0 :(得分：4)

对Java 11字节码的扫描只是merged 4 days ago（在2018年11月1日）。

https://github.com/eclipse/jetty.project/issues/2941

Eclipse Jetty项目正在等待Asm 7.0 final（2018年10月27日发行）的发布，以便可以正确扫描Java 11字节码。

即将发布的Jetty 9.4.13版本应包含此修复程序。

在此期间，您可以：

  • 使用quickstart在构建时生成扫描结果，完全跳过运行时字节码扫描步骤。一些用户报告说，这对他们来说效果很好（甚至缩短了启动时间）。
  • 或使用https://oss.sonatype.org/content/repositories/jetty-snapshots/中的Jetty 9.4.13-SNAPSHOT（直到完成最终的9.4.13版本）
  • 根据Java 8构建类（直到最终的9.4.13版本可用）

确切的错误输出也发生了类似的事情，但是在Anypoint Studio中的Mule API中

Jetty（9.4.12）：无法成功启动上下文o.e.j.w.WebAppContext@2af004b webapp /，不可用

我已经确定了此问题的原因，并通过在pom.xml文件的mule maven插件中添加具有正确的groupId和artifactId的共享库来解决了该问题，尽管我已经指定了<dependencies>部分中的JMS连接器依赖项。

对于任何类似的情况，我建议先在pom / maven中添加以下代码，然后重新测试

<plugin>
    <groupId>org.mule.tools.maven</groupId>
    <artifactId>mule-maven-plugin</artifactId>
    <version>${mule.maven.plugin.version}</version>
    <extensions>true</extensions>
    <configuration>
        <sharedLibraries>
            <sharedLibrary>
                <groupId>34542e45-3432-234e-f45d-345r44533d323</groupId>
                <artifactId>activemq</artifactId>
            </sharedLibrary>
        </sharedLibraries>
    </configuration>
</plugin>

对我来说，它是mule-maven-plugin。我不确定您的平台依赖哪个webApp。因此，相应地放置您的sharedLibrary。
