播放 2.5.3/Ebean: NoSuchMethodError: com.avaje.ebean.config.ServerConfig.getConstraintNaming()

Question

我正在使用 Play 2.5.3 框架，无论出于何种原因，Ebean 在为我的本地（内存中）数据库创建进化时似乎都失败了。这是完整的堆栈跟踪。

谷歌搜索这个异常让我几乎没有任何信息。

在我的“application.conf”文件中，

ebean.default = ["models.*"]

    db {
      # You can declare as many datasources as you want.
      # By convention, the default datasource is named `default`

      # https://www.playframework.com/documentation/latest/Developing-with-the-H2-Database
      default.driver = org.h2.Driver
      default.url = "jdbc:h2:mem:play"
      default.username = sa
      default.password = ""

      # You can turn on SQL logging for any datasource
      # https://www.playframework.com/documentation/latest/Highlights25#Logging-SQL-statements
      #default.logSql=true
    }

这似乎是其他人使用的。我认为也可能是问题的 ebean.properties 文件仅包含

ebean.namingconvention=com.avaje.ebean.config.MatchingNamingConvention

我的 build.sbt 文件如下所示：

name := """Project-CS2340"""

version := "1.0-SNAPSHOT"

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

resolvers ++= Seq(
  "webjars"    at "http://webjars.github.com/m2"
)

scalaVersion := "2.11.7"

libraryDependencies ++= Seq(
  javaJdbc,
  cache,
  javaWs,
  "org.webjars"               %% "webjars-play"       % "2.3.0",
  "org.webjars"               % "bootstrap"           % "3.0.0" exclude("org.webjars", "jquery"),
  "org.webjars"               % "jquery"              % "1.8.3",
  "org.avaje.ebeanorm" % "avaje-ebeanorm" % "4.6.2"
)

playEbeanDebugLevel := 4

fork in run := true

今天早些时候，该应用程序正常运行，我想我更改了一些内容并在休息时忘记了它。老实说，不知道。

Answer 1

在你的 build.sbt 文件中替换 ebean 的库依赖

"org.avaje.ebeanorm" % "avaje-ebeanorm" % "4.6.2"

以下

"org.avaje" % "ebean" % "2.7.3"

祝你好运
