通過Maven Tomcat的Jersey Guice Servlet-404

Question

好的，所以我無法從JerseyGuice獲得HelloWorld，這對我一生都是有效的。 我確信我缺少一些簡單而愚蠢的東西，所以我將把所有這些都扔掉：

它應該通過Maven命令行運行，例如： mvn tomcat7:run

它應該響應： http：// localhost / great / stuff

pom.xml ：（運行配置文件位於最底部）

在gumshoe.guicy.hello是RootModule.java類：

public class RootModule extends JerseyServletModule {

    bind(GuiceContainer.class);

    bind(GreeterService.class);

    serve("/*").with(GuiceContainer.class);
  }
}

在gumshoe.guicy.hello.resources是GreeterService.java類：

public class GreeterService {

    @GET
    @Path("/stuff")
    @Produces("text/plain")
    public String greet(final HttpServletRequest request) {
        return "Hello World!";
    }
}

Answer 1

好吧，我們讓它工作了。
代碼/文件庫存在一系列問題。

1）在web.xml中忽略了一個偵聽器，該偵聽器使整個引導過程停滯了。

2）出現文件結構問題，因為我的Java包位於src而不是Maven預期的src/main/java中。

3）有些傳遞依賴項問題重疊並且導致沖突。 這些是使用pom.xml中的排除標簽修復的。

4）我們缺少一些與Netflix OSS相關的配置文件。

它在http：// localhost：8889 / great / bla / stuff上響應

如果您要嘗試這樣做，除非您確實需要，否則請不要。

這里有龍...

功能文件集如下所示：

web.xml：

<?xml version="1.0" encoding="ISO-8859-1"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-ins...>
    <display-name>My Awesome REST API App</display-name>

    <filter>
        <filter-name>guiceFilter</filter-name>
        <filter-class>com.google.inject.servlet.GuiceFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>guiceFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <listener>
        <listener-class>com.netflix.karyon.server.guice.KaryonGuiceContextListener</listener-class>
    </listener>
</web-app>

新文件： config.properties ：在.../src/main/resources/

archaius.deployment.applicationId=helloworldservice
com.netflix.karyon.eureka.disable=true

新文件： .../src/main/resources/ helloworldservice.properties

com.netflix.karyon.server.bootstrap.class=gumshoe.guicy.hello.Bootstrap
netflix.platform.admin.resources.port=9092

gumshoe.hello.guicy.RootModule.java ：

public class RootModule extends JerseyServletModule {

@Override
protected void configureServlets() {

    final HashMap<String, String> initParams = new HashMap<String, String>();

    initParams.put(PackagesResourceConfig.PROPERTY_PACKAGES,
            "gumshoe.guicy.hello");

    bind(GuiceContainer.class);

    bind(GreeterService.class);

    serve("/*").with(GuiceContainer.class);
}
}

gumshoe.guicy.hello.resources.GreeterService.java ：

@Path("/bla")
public class GreeterService {

    @GET
    @Path("/stuff")
    @Produces("text/plain")
    public String greet() {
        return "Hello World!";
    }
}

新類： gumshoe.guicy.hello.Bootstrap.java ：

public class Bootstrap extends ServerBootstrap {

    @Override
    protected void configureBootstrapBinder(BootstrapBinder binder) {


        System.out.println("Bootstrap");

        binder.install(new RootModule());

    }
}

最后但並非最不重要的一點是，在插件運行時下添加了一堆依賴項和一個archaius標記的pom.xml：
