我正在尝试使用Payara Micro(5.191)和xsbt-web-plugin(4.0.2)设置服务。
build.sbt:
ThisBuild / organization := "local.test"
ThisBuild / version := "0.1.0-SNAPSHOT"
ThisBuild / scalaVersion := "2.12.8"
lazy val testService = project
.enablePlugins(ContainerPlugin)
.settings(
javaOptions in Container ++= Seq("-Xdebug", "-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005"),
libraryDependencies ++= Seq(
microprofile,
servlet
),
containerLibs in Container := Seq(
"fish.payara.extras" % "payara-micro" % "5.191"
),
containerLaunchCmd in Container := { (port, path) =>
Seq("fish.payara.micro.PayaraMicro")
}
)
lazy val microprofile = {
sys.props += "packaging.type" -> "jar"
"org.eclipse.microprofile" % "microprofile" % "2.2" % "provided" pomOnly()
}
lazy val servlet = "javax.servlet" % "javax.servlet-api" % "4.0.1" % "provided"
Main.scala:
package local.test
import java.util
import javax.ws.rs.ApplicationPath
import javax.ws.rs.core.Application
import local.test.endpoint.Hello
@ApplicationPath("/*")
class Main extends Application {
override def getClasses: util.Set[Class[_]] = {
val h = new util.HashSet[Class[_]]
h.add(classOf[Hello])
h
}
}
Hello.scala:
package local.test.endpoint
import javax.ws.rs.core.{MediaType,Response}
import javax.ws.rs.{GET, Path, Produces, QueryParam}
@Path("/hello")
class Hello {
@GET
@Produces(Array(MediaType.TEXT_PLAIN))
def getMessage(@QueryParam("name") name: String): Response = {
Response.ok("Hallo " + name).build
}
@GET
@Produces(Array(MediaType.TEXT_PLAIN))
def getMessage: Response = {
Response.ok("Hallo Nobody").build
}
}
服务器启动,没有显示错误,但是我无法打开网站。
1)http://localhost:8080/test是正确的URL吗?
2)如何检查此应用程序是否已部署?
3)我想念什么?
答案 0 :(得分:1)
在Earldouglas的帮助下(非常感谢),我开始运行它:
项目文件:
/project-root
+ project/
| + build.properties (single line content: sbt.version=1.2.8)
| + plugins.sbt (single line content: addSbtPlugin("com.earldouglas" % "xsbt-web-plugin" % "4.0.2") )
|
+ src/main/
| + scala/local/test/
| | + endpoint/
| | | + Hello.scala
| | + Main.scala
| + webapp/WEB-INF/
| + web.xml
|
+ build.sbt
Hello.scala:就像上面的问题一样,但是删除第二个GET请求。同一端点上的两个相等的请求不起作用。
Main.scala:请参见上文
web.xml:
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
version="3.1">
</web-app>
build.sbt:与上面类似,但是替换行
containerLaunchCmd in Container := { (port, path) =>
Seq("fish.payara.micro.PayaraMicro")
}
使用
containerLaunchCmd in Container := { (port, path) =>
Seq("fish.payara.micro.PayaraMicro", "--deploy", "target/webapp", "--contextroot", "/")
}
,并将项目val更改为
lazy val testService = (project in file("."))
也许您想根据需要更改contextroot。
每次更改源代码后,您都需要运行container:start
。
payara micro启动后,您可以对其进行检查:
curl localhost:8080/hello
curl localhost:8080/application.wadl
