Jackson 'NoSuchMethodError: com.fasterxml.jackson.databind.introspect.AnnotatedMember.getType' error when upgrading Play project dependencies

Question

我正在更新一个旧的 Play 项目并升级到最新版本的 Play，但我在使用 swagger 时遇到了一些问题。

我收到此错误，但我不知道如何解决：

Error injecting constructor, java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.introspect.AnnotatedMember.getType(Lcom/fasterxml/jackson/databind/type/TypeBindings;)Lcom/fasterxml/jackson/databind/JavaType;

我的配置文件如下：

build.sbt

name := """accepter"""

version := "1.0-SNAPSHOT"

lazy val root = (project in file(".")).enablePlugins(SbtPlugin, PlayJava, PlayEbean)

scalaVersion := "2.12.12"

Test / javaOptions += "-Dconfig.file=conf/application.test.conf"

plugins.sbt

addSbtPlugin("com.typesafe.sbt" % "sbt-play-enhancer" % "1.2.2")


addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "5.2.4")
addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "6.0.0")

有谁知道什么可能有帮助，或者错误可能出在哪里？

Answer 1

主要障碍是 Play 2.8.8 与 Jackson 2.11.x 兼容，而不是 2.12.x。您必须确保只使用 Jackson 2.11.x.

我建议您运行 sbt dependencyBrowseTree 查看依赖关系树并确保在所有依赖关系中只使用 Jackson 版本。您也可以定义一些 overrideDependencies 以帮助保持一致性。

您还可能需要：

要么摆脱不再维护且与 Play 2.8 和 Jackson 2.11 不兼容的 swagger-play2
或者，使用 swagger-play2 的分支 https://github.com/dwickern/swagger-play
