Dropwizard RequestLog

Question

在集成测试我的Dropwizard 0.9.2服务时，我有一个奇怪的异常。异常和配置如下。

我不明白为什么requestLog是未知的？DW文档说，下面的配置部分应该可以工作。requestLog可以在

io.dropwizard.server.AbstractServerFactory.class

和

io.dropwizard.server.DefaultServerFactory.class

扩展它，所以应该可以使用requestLog。这里出什么问题了？

有人已经知道这个问题了吗？

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

异常

Answer 1

我们也有同样的问题。这是一个问题，使用一个老版本的杰克逊。我们已经从v 2.6.3升级到v 2.6.5，并且错误消失了。

Answer 2

尝试将timeZone: UTC放在每个附录下面，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
  applicationConnectors:
    - type: http
      port: 80
  adminConnectors:
    - type: http
      port: 12345

Answer 3

对于最近版本的杰克逊，我也出现了同样的错误，当时我添加了一个引入com.fasterxml.jackson.core:jackson-databind:jar:2.7.2的依赖项

将jackson-databind排除在pom.xml中的依赖项之外解决了这个问题。
