Question

这里是代码：

package de.swt1321.servlet;

import java.io.OutputStream;

import javax.servlet.http.annotation.Servlet;
import javax.servlet.http.annotation.GET;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@Servlet(urlMappings={"/ServletTest"})
public class ServletTest {
    private static final java.nio.charset.Charset UTF8 = java.nio.charset.Charset.forName("UTF8");
    @GET
    public void handleGet(HttpServletRequest req,
                          HttpServletResponse res)
    {
        byte[] HTML = "<html><head><title>Hello World!</title></head><body><h1>IT WORKED!</h1></body></html>".getBytes(UTF8);
        res.setStatus(HttpServletResponse.SC_OK);
        res.setHeader("content-type","text/html;charset=utf8");
        res.setIntHeader("content-length",HTML.length);
        OutputStream os = res.getOutputStream();
        os.write(HTML);
        os.flush();
    }
}

我希望这可以根据this工作，遗憾的是我到目前为止还没找到包含javax.servlet.http.annotation包的jar。我查看了来自http://download.java.net/maven/2的“javax：javaee-api：jar：6.0”以及Jetty 9附带的servlet-api-3.0.jar，但到目前为止还没有运气。我在这里有点想法，我缺少什么？

到目前为止，我正在使用此Buildr构建文件构建/尝试构建：

# Version number for this release
VERSION_NUMBER = "1.0.0"
# Group identifier for your projects
GROUP = "swt1321"
COPYRIGHT = ""

# Specify Maven 2.0 remote repositories here, like this:
repositories.remote << "http://repo1.maven.org/maven2"

# This really bugs me, this isn't only supposed to build on my own PC after all!
# But as I said, the one at the download.java.net repo didn't work
JAVA_EE_PATH = "/home/hannes/Lib/Java/jetty-distribution-9.0.0.M3/lib/servlet-api-3.0.jar"
java_ee = artifact("de.swt1321:java_ee:jar:1.0").from(file JAVA_EE_PATH)

project_layout = Layout.new
project_layout[:source,:main,:java] = 'src'
project_layout[:source,:test,:java] = 'test'

desc "The Servlettest project"
define "ServletTest", :layout => project_layout do
  project.version = VERSION_NUMBER
  project.group = GROUP
  manifest["Implementation-Vendor"] = COPYRIGHT
  compile.with java_ee
  package :war
end

Answer 1

这个包是servlet-api.jar的子包，你可以在容器的lib文件夹中找到这个jar文件。对于tomcat来说 [tomcat安装目录] - ＆gt; lib-＆gt; servlet-api.jar

Answer 2

我建议您快速浏览一下more updated example网络servlet api

尽管如此，如果您仍在寻找2008年示例中使用的库，我会根据Jarvana

建议您使用这些库。

Maven:  

<dependency>
   <groupId>org.mortbay.jetty</groupId>
   <artifactId>servlet-annotation-spec</artifactId>
   <version>3.0.pre0</version>
</dependency>

BONUS：您的GET注释似乎属于another package

我从哪里获取javax.servlet.http.annotation包？
