Uzyskiwanie błąd pliku skanowania podczas pracy na java jetty 9 8 za pomocą wtyczki Maven molo

Question

biegnę trywialny aplikacji internetowej za pomocą servlet-3.1Hello World, jetty-9 działa na jdk-8 i używając maven-jetty-plugin.

public class HelloWorldServlet extends HttpServlet { 

    @Override 
    protected void doGet(HttpServletRequest request, HttpServletResponse response) { 
     try { 
      String message = "Hello Jetty From the HelloWorldServlet"; 
      OutputStream stream = response.getOutputStream(); 
      stream.write(message.getBytes()); 
      stream.flush(); 
     } catch (IOException ex) { 
      Logger.getLogger(HelloWorldServlet.class.getName()).log(Level.SEVERE, null, ex); 
     } 
    } 

I dobrze odwzorowany w pliku web.xml:

<servlet> 
     <servlet-name>hello</servlet-name> 
     <servlet-class>org.tarrsalah.jetty.example.HelloWorldServlet</servlet-class>     
    </servlet> 

    <servlet-mapping> 
     <servlet-name>hello</servlet-name> 
     <url-pattern>/*</url-pattern> 
    </servlet-mapping> 

Ale wydaje się, że pomost nie mogą fin moją klasę serwletu przy uruchamianiu mvn jetty: run, co ja tu brakuje?

Pracował po zmianie konfiguracji maven-compiler-plugin od 1,8 do 1,7, What'is złego korzystania z java-8jetty-9?

Answer 1

Ze względu na różnice między wersja Java (8), a wersja ASM dołączonego w Jetty masz rodzaj wyjątkami masz doświadczenie.

Musisz zrobić wersje zgodną ze sobą pobieraniaASM5,0 lub większą i wymiany następujących 2 pliki w instalacji Jettyfolder:

1.asm-4.1.jarzasm-5.0_BETA.jar

2.ASM-Commons 4.1.jarzasm-commons-5.0_BETA.jar

Answer 2

Aby dokonać tej pracy, trzeba dodać ASM 5 do zależnościami pomostu-maven- wtyczka na razie

<plugin> 
    <groupId>org.eclipse.jetty</groupId> 
    <artifactId>jetty-maven-plugin</artifactId> 
    <dependencies> 
     <dependency> 
      <groupId>org.ow2.asm</groupId> 
      <artifactId>asm</artifactId> 
      <version>5.0.2</version> 
     </dependency> 
     <dependency> 
      <groupId>org.ow2.asm</groupId> 
      <artifactId>asm-commons</artifactId> 
      <version>5.0.2</version> 
     </dependency> 
    </dependencies> 
</plugin> 

Answer 3

check to

http://vaskoz.wordpress.com/2013/12/18/fix-jetty-9-1-for-jdk8-annotations/

Jetty 9.1.0 comes bundled with ASM 4.1 but running with bytecode level 1.8 and annotations causes the following error: java.lang.RuntimeException: Error scanning file PingController.class at org.eclipse.jetty.annotations.AnnotationParser.parseDir(AnnotationParser.java:705)
