我的应用正在抛出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？
我也有这个代码用于引用,但我认为这不是问题：
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);
我的应用程序正在使用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,它会抛出此异常
错误：
[INFO] Caused by: java.lang.NoSuchMethodError: com.google.common.base.Stopwatch.createStarted()Lcom/google/common/base/Stopwatch; [INFO] at org.restlet.ext.apispark.internal.firewall.rule.counter.PeriodicCounter.<init>(PeriodicCounter.java:65) [INFO] at org.restlet.ext.apispark.internal.firewall.rule.PeriodicFirewallCounterRule$1.load(PeriodicFirewallCounterRule.java:86) [INFO] at org.restlet.ext.apispark.internal.firewall.rule.PeriodicFirewallCounterRule$1.load(PeriodicFirewallCounterRule.java:84) [INFO] at com.google.common.cache.LocalCache$LoadingValueReference.loadFuture(LocalCache.java:3599) [INFO] at com.google.common.cache.LocalCache$Segment.loadSync(LocalCache.java:2379) [INFO] at com.google.common.cache.LocalCache$Segment.lockedGetOrLoad(LocalCache.java:2342) [INFO] at com.google.common.cache.LocalCache$Segment.get(LocalCache.java:2257) [INFO] ... 74 more
解决方法
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.
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)
它位于从头开始创建的应用程序中,具有以下maven配置：

我整合了你的代码,它在我身边很好用.没有例外被抛出……
我认为Guava的旧版本来自另一个依赖.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……
希望能帮助你,蒂埃里
