NoSuchMethodError：com.google.common.base.Stopwatch.createStarted（）Lcom / google / common / base / Stopwatch [英] NoSuchMethodError: com.google.common.base.Stopwatch.createStarted()Lcom/google/common/base/Stopwatch

问题描述

我的应用正在投掷 NoSuchMethodError：com.google.common.base.Stopwatch.createStarted（）Lcom / google / common / base / Stopwatch 错误。不知道为什么，因为16.0.1确实包含那个类，我已经检查了。根据我的研究，看起来这是一个错误？

My app is throwing NoSuchMethodError: com.google.common.base.Stopwatch.createStarted()Lcom/google/common/base/Stopwatch error. Not sure why, because 16.0.1 do contain that class, I've checked. From what I have researched, it looks like this is a bug?

我也有这个代码用于推荐，但我认为这不是问题：

I also have this code for refernence, though I think this is not the issue:

    FirewallRule rule = new PeriodicFirewallCounterRule(60, TimeUnit.SECONDS, new IpAddressCountingPolicy());
    ((PeriodicFirewallCounterRule)rule).addHandler(new RateLimitationHandler(new UniqueLimitPolicy(10)));
    FirewallFilter firewallFiler = new FirewallFilter(getContext(), list(rule));
    firewallFiler.setNext(ma);

我的应用正在使用Restlet APISpark：

My app is using Restlet APISpark:

  <dependency>
      <groupId>org.restlet.gae</groupId>
      <artifactId>org.restlet.ext.apispark</artifactId>
      <version>${version.restlet}</version>
  </dependency>

当运行并访问应用程序的REST api时，它会抛出
错误：

When running and accessing the REST api of the app, it throws this error:

[INFO] Caused by: java.lang.NoSuchMethodError: com.google.common.base.Stopwatch.createStarted()Lcom/google/common/base/Stopwatch;

推荐答案

当使用扩展名 org.restlet.ext.apispark 时，检索到的guava依赖项的版本为 16.0.1 。

When using the extension org.restlet.ext.apispark, the guava dependency retrieved has the version 16.0.1.

Downloading: http://maven.restlet.com/com/google/guava/guava/16.0.1/guava-16.0.1.jar
Downloading: http://repo.maven.apache.org/maven2/com/google/guava/guava/16.0.1/guava-16.0.1.jar
Downloaded: http://repo.maven.apache.org/maven2/com/google/guava/guava/16.0.1/guava-16.0.1.jar (2176 KB at 711.7 KB/sec)

它来自一个从头创建的应用程序，具有以下maven配置：

It comes within an application created from scratch with the following maven configuration:

我整合了你的代码，它在我身边很好用。没有异常被抛出......

I integrated your code and it works fine on my side. No exception is thrown...

我认为旧版本的Guava来自另一个依赖项。如果你使用Maven，你应该确定这个旧的番石榴版本来自哪里，并且可能在相应的依赖项中添加一个排除。我希望它能解决你的问题...

I think that an older version of Guava comes from another dependency. If you use Maven, you should identify where this old guava version comes from and perhaps add an exclude within the corresponding dependency. I hope that it will fix your problem...
