Question

我试图创建一个简单的RestHelper“Hello world”示例，但我遇到了麻烦。当我使用container:start命令启动我的容器时，

serve {
    case Nil Get _ => Extraction.decompose("Hello Restful world!")
  }

我的RestHelper扩展程序中未调用

。我收到以下消息： “在此服务器上找不到请求的网址”

所以，似乎由于某种原因，提升忽略了

LiftRules.statelessDispatch.append(Service)

bootstrap.Boot.boot定义中的行。而且我完全不知道为什么会这样。

这是我的Boot课程：

package bootstrap

import net.liftweb.http.LiftRules
import com.yac.restfultest.Service

class Boot {
  def boot {
    LiftRules.statelessDispatch.append(Service)
  }
}

这里是Service：

package com.yac.restfultest

import net.liftweb.http.rest.RestHelper
import net.liftweb.json.Extraction

object Service extends RestHelper {

  serve {
    case Nil Get _ => Extraction.decompose("Hello Restful world!")
  }

}

如果它有帮助，我的web.xml：

<!DOCTYPE web-app SYSTEM "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
    <filter>
        <filter-name>LiftFilter</filter-name>
        <display-name>Lift Filter</display-name>
        <description>The Filter that intercepts Lift calls</description>
        <filter-class>net.liftweb.http.LiftFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>LiftFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

如果上述所有内容都不够，我的build.sbt：

name := "TestRest"

version := "1.0"

scalaVersion := "2.11.6"

resolvers ++= Seq("snapshots" at "https://oss.sonatype.org/content/repositories/snapshots",
  "releases" at "https://oss.sonatype.org/content/repositories/releases"
)

jetty()

libraryDependencies ++= {

  val liftVersion = "2.6.2"

  Seq(
    "net.liftweb" %% "lift-webkit" % liftVersion % "compile"
  )

}

正如您所看到的，这几乎是最简约的升降机项目设置。我仍然无法让它发挥作用。任何帮助将不胜感激。

此处sbt登录container:start：

Answer 1

所以，事实证明这是一种常见的非注意力。包含assign leadingBits = magnitude[bitsEnd+3 -: 4];的包应该被称为Boot.scala，而不仅仅是bootstrap.liftweb。

是的，正如 jcern 所建议的那样，在路由模式中它应该是bootstrap。

Lift RestHelper不接收我的请求
