Tomcat 7在使用Jersey 2時不會掃描註釋

我有一個Jersey 2 Maven項目。Tomcat 7在使用Jersey 2時不會掃描註釋

的web.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<!-- This web.xml file is not required when using Servlet 3.0 container, 
see implementation details http://jersey.java.net/nonav/documentation/latest/jax-rs.html --> 
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> 
    <servlet> 
     <servlet-name>com.api.rest.ApplicationResource</servlet-name> 
     <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>   
     <load-on-startup>1</load-on-startup> 
    </servlet> 
    <servlet-mapping> 
     <servlet-name>com.api.rest.ApplicationResource</servlet-name> 
     <url-pattern>/api/*</url-pattern> 
    </servlet-mapping> 
</web-app>

的pom.xml：在本地工作時

我的項目工作正常。但是當我將它部署在遠程服務器上時，它不再工作。

所以會發生什麼基本上是WAR正確部署，但在catalina.out中確實沒有錯誤或警告。我在每個定義的端點上都有404。

catalina.out的：

Sep 14, 2015 2:03:00 PM org.apache.catalina.startup.HostConfig deployWAR 
INFO: Deploying web application archive /var/lib/tomcat7/webapps/GLI_API.war

Sep 14, 2015 2:04:23 PM org.apache.catalina.startup.Catalina start 
INFO: Server startup in 84867 ms

ApplicationResource：

package com.api.rest; 

import java.util.logging.Logger; 


import org.glassfish.jersey.filter.LoggingFilter; 
import org.glassfish.jersey.server.ResourceConfig; 
import org.glassfish.jersey.server.ServerProperties; 
import com.api.provider.ResponseCorsFilter; 
import org.glassfish.jersey.media.multipart.MultiPartFeature; 


public class ApplicationResource extends ResourceConfig { 

    private static final Logger LOGGER = null; 


    public ApplicationResource() { 
     // Register resources and providers using package-scanning. 
     packages("com.api"); 
     System.out.println("started"); 

     register(MultiPartFeature.class); 

     // Register my custom provider - not needed if it's in my.package. 
     register(ResponseCorsFilter.class); 
     // Register an instance of LoggingFilter. 
     register(new LoggingFilter(LOGGER, true)); 

     // Enable Tracing support. 
     property(ServerProperties.TRACING, "ALL"); 
    } 
}

可能是什麼問題呢？我在tomcat8上開發（但不記得使用特定的東西）並部署在tomcat7上。這可能是一個問題嗎？

此端點應該可以訪問：http://54.228.220.152:8080/GLI_API/api/item

其他API工作正常 - 所以一般服務器正常工作。

另外 - 如果你沒有最終答案，我會很感激，如果你可以指向我的文件/目錄來看看，因爲我沒有得到任何錯誤。

你可以設置<時加載的啓動> 1 0或-1？ – Stefan

你可以粘貼你的API控制器代碼嗎？ –

也許這個職位可以幫助 - http://stackoverflow.com/questions/17616708/rest-service-errors-with-resource-is-not-available-glassfish-4-0-jax-rs-2-0 –

你可以試試這個初始化參數設置爲你的servlet，使註釋掃描：

<servlet> 
... 
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class> 

<init-param> 
    <param-name>jersey.config.server.provider.packages</param-name> 
    <param-value>com.yourproject.packageWhereYourResourcesAre</param-value> 
</init-param> 
... 
</servlet>

更新

看來你已經對Java的8編，而Tomcat的與Java 7運行？試試這個：

<configuration> 
    <source>1.7</source> 
    <target>1.7</target> 
</configuration>

您可能還需要更新您的web.xml中3.0：

<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

非常感謝 - 這有助於我獲得不受支持的主要次要版本現在我可以在哪裏工作我以爲我在我的控制器中有這個：packages（「com.api」）; 有什麼區別？我有時非常困惑web.xml和我的ApplicationController –

結果：我編譯在JDK 1.8中，但沒有在服務器上 - ouch :( –
