Twilio/Dropwizard运行时错误

分类: 技术问答 • 2022-08-01 09:21:41
问题描述：

我想让Twilio在Dropwizard应用程序中工作。该程序编译，但我在引导服务器时不断得到以下失败。Twilio/Dropwizard运行时错误

$ sudo ./startpiservice.sh 
Exception in thread "main" java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/type/ReferenceType at com.fasterxml.jackson.datatype.guava.GuavaModule.setupModule(GuavaModule.java:55) at com.fasterxml.jackson.databind.ObjectMapper.registerModule(ObjectMapper.java:550) at io.dropwizard.jackson.Jackson.configure(Jackson.java:54) at io.dropwizard.jackson.Jackson.newObjectMapper(Jackson.java:24) at io.dropwizard.setup.Bootstrap.<init>(Bootstrap.java:64) at io.dropwizard.Application.run(Application.java:72) at applicationconfiguration.HomeApplication.main(HomeApplication.java:71) Caused by: java.lang.ClassNotFoundException: com.fasterxml.jackson.databind.type.ReferenceType at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 7 more

整个文件可以在这里找到我的Dropbox的...对不起，我在我的日常工作，而不能访问github上上传这里面。

https://www.dropbox.com/sh/or5v14uyyjplvmr/AAB4uoHdRDYLZVylUfGNotkfa?dl=0

有问题的类是在SMSResource.java \ pirestservice的\ src \主\ java的\资源\ SMSResource.java

代码编译并运行没有任何代码语句和进口的Twilio，但是一旦我使用导入语句和代码语句，程序在引导期间就会失败。

我是相对较新的使用Maven和Dropwizard ......这是一个问题与依赖冲突？我错过了什么吗？ Twilio代码工作在一个简单的独立程序中，但不在Dropwizard中。

~~~~~~~~~~~~~~~~~~~~~~ UPDATE 2017年3月2日~~~~~~~~~~~~~~~~~

根据hortega的建议，我修改了我的Maven POM文件并编译了程序，并在部署时运行了服务器。所有的方法调用工作，除了我需要的是“/ sendms”。这是POM文件，java类文件和堆栈跟踪的一部分。

你缺少杰克逊依赖。将此添加到您的pom.xml中

<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-core --> 
<dependency> 
    <groupId>com.fasterxml.jackson.core</groupId>

谢谢。我会在今晚或明天回家后告诉你，情况如何。 – mike

我添加了这些依赖关系，但应用程序在引导期间仍然崩溃。完全相同的错误。 :-( – mike

答

您的两个依赖项正在提取不同版本的Jackson库。这里mvn dependency:tree -Dverbose是你的朋友，它会告诉你哪些依赖关系冲突：

... 
[INFO] +- io.dropwizard:dropwizard-core:jar:1.0.5:compile 
[INFO] | +- io.dropwizard:dropwizard-util:jar:1.0.5:compile 
[INFO] | | +- (com.fasterxml.jackson.core:jackson-annotations:jar:2.7.8:compile - omitted for conflict with 2.4.3) 
... 
[INFO] \- com.twilio.sdk:twilio:jar:7.5.0:compile 
... 
[INFO] +- com.fasterxml.jackson.core:jackson-databind:jar:2.4.3:compile 
[INFO] | +- (com.fasterxml.jackson.core:jackson-annotations:jar:2.4.0:compile - omitted for conflict with 2.4.3) 
...

你可以在这里看到dropwizard-core和twilio使用不同版本的不同杰克逊包。通常，当你看到这个时，Maven使用错误版本的机会很大，因为它没有足够的信息。所以我们应该告诉它要使用哪个版本的Jackson（通常我们选择最新版本）。有几个方法可以做到这一点：

  1. 依赖管理：添加争食依赖内该块可以让你选择自己的整个项目的版本。添加下一个块的<dependencies>外：

    <dependencyManagement> 
    <dependencies> 
     <dependency> 
      <groupId>com.fasterxml.jackson.core</groupId> 
      <artifactId>jackson-core</artifactId> 
      <version>2.7.8</version> 
     </dependency> 
     <dependency> 
      <groupId>com.fasterxml.jackson.core</groupId> 
      <artifactId>jackson-annotations</artifactId> 
      <version>2.7.8</version> 
     </dependency> 
     <dependency> 
      <groupId>com.fasterxml.jackson.core</groupId> 
      <artifactId>jackson-databind</artifactId> 
      <version>2.7.8</version> 
     </dependency> 
    </dependencies> 
</dependencyManagement>

  2. 对你的依赖排除包：这种方式给你一个更细粒度的控制。只需将<exclusions>块添加到您要忽略这些软件包版本的依赖项中即可。在这种情况下，将会是Twilio，因为它有冲突库的最旧版本。

    <dependency> 
    <groupId>com.twilio.sdk</groupId> 
    <artifactId>twilio</artifactId> 
    <version>7.5.0</version> 
    <exclusions> 
     <exclusion> 
      <groupId>com.fasterxml.jackson.core</groupId> 
      <artifactId>jackson-core</artifactId> 
     </exclusion> 
     <exclusion> 
      <groupId>com.fasterxml.jackson.core</groupId> 
      <artifactId>jackson-annotations</artifactId> 
     </exclusion> 
     <exclusion> 
      <groupId>com.fasterxml.jackson.core</groupId> 
      <artifactId>jackson-databind</artifactId> 
     </exclusion> 
    </exclusions> 
</dependency>

当你开始使用Maven这个问题会咬你了几次，但dependencies插件是真正有用的在这里。

我在twilio-java上创建了一个PR来升级这些依赖关系，但是如果您不想等待使用上述方法之一。

谢谢你，你的建议很有效，我可以编译和运行服务器，但是，我收到了另外一个错误，我将用堆栈跟踪和java类文件编辑我的帖子。 – mike

我找到了这个问题的真正答案。问题在于Ubuntu Mate for Raspberry Pi发行版中提供的JVM。他们提供OpenJDK。经过多次在线调试后，我开始将操作系统和JVM视为我的问题的来源，并且当我将OpenJDK换成Oracle JDK时，一切都按照我的预期工作。
