Question

我在PlayFramework内部记录时遇到了一些问题。

我有一个依赖，似乎带来了int isNumericFloat(float value); // I don't really know what arguments it takes // but you can surely infer them from the code，显然与Play的内部日志记录有冲突。在当前形式中，在"org.slf4j", "slf4j-log4j12"时，它给了我这个例外：

compile

但是排除它会使它编译：

java.lang.ClassCastException: org.slf4j.impl.Log4jLoggerFactory cannot be cast to ch.qos.logback.classic.LoggerContext
    at play.api.libs.logback.LogbackLoggerConfigurator.configure(LogbackLoggerConfigurator.scala:80)

    at scala.Function1$$anonfun$compose$1.apply(Function1.scala:47)

但是给出了运行时异常：

    projectDependencies := {
      Seq((projectID in root).value.exclude("org.slf4j", "slf4j-log4j12"))
    }

因为我系统的某些内部组件使用此日志记录。任何想法如何解决这个日志记录依赖的噩梦？

Answer 1

您只需要从冲突的包中排除log4j依赖关系，而不是整个项目。

示例：

libraryDependencies += "tf56" % "risk" % "1.0.3" exclude("org.slf4j", "slf4j-log4j12")

如何在PlayFramework中处理日志记录依赖项
