Dropwizard RequestLog | 易学教程

问题

I have an strange exception while integration testing my Dropwizard 0.9.2 service. The exception and configuration are below.

I dont understand why requestLog is unknown? The DW documentation say, that below configuration part should work. The requestLog can be found in

io.dropwizard.server.AbstractServerFactory.class

and

io.dropwizard.server.DefaultServerFactory.class

extends it, so it should be possible to use the requestLog. Whats wrong here?

Someone knows this problem already?

Configuration Part

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

回答1:

we had the same issue. It was a problem of using an older version of Jackson. We'Ve upgraded from v 2.6.3 to v 2.6.5 and the error was gone.

回答2:

The same error arose for me with more recent versions of jackson, when I added a dependency that pulled in com.fasterxml.jackson.core:jackson-databind:jar:2.7.2

Excluding jackson-databind from that dependency in pom.xml resolved it.

回答3:

Try to put timeZone: UTC under each appender like this:

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
