Exception Dropwizard请求日志

集成测试Dropwizard 0.9.2服务时出现了一个奇怪的异常。异常和配置如下所示

我不明白为什么requestLog是未知的？也就是说，下面的配置部分应该可以工作。可以在中找到requestLog

io.dropwizard.server.AbstractServerFactory.class

及

io.dropwizard.server.DefaultServerFactory.class

扩展它，因此应该可以使用requestLog。这里怎么了

有人已经知道这个问题了

配置部分

server:
  requestLog:
    timeZone: UTC
    appenders:
     - type: console
       threshold: DEBUG
     - type: file
       currentLogFilename: ./log/access.log
       threshold: ALL
       archive: true
       archivedLogFilenamePattern: ./log/access.%d.log.gz
       archivedFileCount: 14
  maxThreads: 1024
  minThreads: 8
  maxQueuedRequests: 1024
  applicationConnectors:
    - type: http
      port: 80
  adminConnectors:
    - type: http
      port: 12345

我们有同样的问题。这是一个使用旧版本杰克逊的问题。我们已经从v

2.6.3

升级到v

2.6.5

，错误消失了。

我在更新版本的jackson中也出现了同样的错误，当时我添加了一个依赖项，该依赖项拉入了

com.fasterxml.jackson.core:jackson-databind:jar:2.7.2

从pom.xml中的依赖项中排除

jackson-databind

可以解决此问题。

尝试将时区：UTC放在每个附录下，如下所示：

server:
  requestLog:
    appenders:
     - type: console
       threshold: DEBUG
       timeZone: UTC
     - type: file
       currentLogFilename: ./log/access.log
       threshold: ALL
       archive: true
       archivedLogFilenamePattern: ./log/access.%d.log.gz
       archivedFileCount: 14
       timeZone: UTC
  maxThreads: 1024
  minThreads: 8
  maxQueuedRequests: 1024

你能把你用来测试的代码也贴出来吗？这对我很有用。我猜你使用的版本有问题。也许您在类路径中有一个较旧版本的DW？它正在工作，但是如果我使用集成测试TestRule，它就会失败。如果我创建并运行jar，也会发生这种情况。有什么办法解决这个问题吗？服务器工厂类是否未加载或加载错误？如何检查此问题？将服务器类型设置为默认值可以解决此问题，但现在我在启动期间遇到一些验证异常…也适用于从2.7.0升级到2.7.3的情况
