泽西Guice Servlet通过Maven Tomcat - 404

Question

好的，所以我无法让JerseyGuice的HelloWorld在我的生命中工作。 我确信我错过了一些简单而愚蠢的东西，所以我只想把所有这些都丢掉：

它应该通过Maven命令行运行，如： .ssh

应该回复：http://localhost/great/stuff

pom.xml :(运行配置文件位于最底层）

mvn tomcat7:run

的web.xml：

和public class RootModule extends JerseyServletModule { @Override protected void configureServlets() { bind(GuiceContainer.class); bind(GreeterService.class); serve("/*").with(GuiceContainer.class); } } 中的GreeterService.java类：

gumshoe.guicy.hello.resources

Answer 1

好的，我们让它运转起来 代码/文件库存在一系列问题。

1）在web.xml中忽略了一个停止整个引导过程的监听器。

2）存在文件结构问题，因为我的Java软件包位于src而不是Maven所期望的src/main/java。

3）存在一些重叠并导致冲突的传递依赖问题。这些是使用pom.xml中的排除标记修复的。

4）我们缺少一些与Netflix OSS相关的配置文件。

它以http://localhost:8889/great/bla/stuff

作出回应

如果你想这样做......不要......除非你真的需要它。

这里有龙......

功能文件集如下所示：

的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：.../src/main/resources/

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

helloworldservice.properties

中的新文件.../src/main/resources/

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!";
    }
}

新课程：gumshoe.guicy.hello.Bootstrap.java：

public class Bootstrap extends ServerBootstrap {

    @Override
    protected void configureBootstrapBinder(BootstrapBinder binder) {


        System.out.println("Bootstrap");

        binder.install(new RootModule());

    }
}

最后但并非最不重要的是，在插件运行时下添加了一堆依赖项和archaius标记的pom.xml：
