本项目是将restful项目打包成可执行的war包，在docker中执行
环境介绍：
docker 1.10.3
jetty 8
jersey 1.19
关键配置：
1、pom.xml配置

2、启动类
|
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.net.URL;
import java.security.ProtectionDomain;
import java.util.Properties;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.webapp.WebAppContext;
public final class Launcher {
public static void main(String[] args) throws Exception {
ProtectionDomain domain = Launcher.class.getProtectionDomain();
URL location = domain.getCodeSource().getLocation();
WebAppContext webapp = new WebAppContext();
webapp.setContextPath("/");
webapp.setWar(location.toExternalForm());
//as enumerated from http://jira.codehaus.org/browse/JETTY-1256
String[] configurations = new String[]{
"org.eclipse.jetty.webapp.WebInfConfiguration"

//,"org.eclipse.jetty.annotations.ContainerInitializerConfiguration"
};
webapp.setAttribute("org.eclipse.jetty.webapp.configuration", configurations);
webapp.setConfigurationClasses(configurations);
int port = 8080;
try{
//NOTE: default port in CONFIGPATH file is 8383
port = Integer.parseInt( load(new File(System.getProperty("CONFIGPATH"))).getProperty("jetty.port"));
}catch(Exception e){
e.printStackTrace();
System.out.println("ERROR: Invalid jetty.port value in configuration file.");
}
Server server = new Server(port);
server.setHandler(webapp);
server.start();
server.join();
}
private static Properties load(File propsFile) throws IOException {
Properties props = new Properties();
FileInputStream fis = null;
try{
fis = new FileInputStream(propsFile);
props.load(fis);
}finally{
try{
fis.close();
}catch(Exception e){
}
}
return props;
}
}

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

</servlet>
<servlet-mapping>
<servlet-name>Rest_Servlet</servlet-name>
<!-- Redirect any calls to our jersey servlet -->
<url-pattern>/test/*</url-pattern>
</servlet-mapping>
<!-- 添加解决跨域的代码配置，基于pom中有cors-filter的依赖 ，begin -->
<filter>
<filter-name>CORS</filter-name>

</init-param>
</filter>
<filter-mapping>
<filter-name>CORS</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 添加解决跨域的代码配置，基于pom中有cors-filter的依赖 ，end -->

4、配置文件conf.properties
|
jetty.port=8080
database.url=
database.driver_class=
database.user=
database.password=
hibernate.show_sql=false
|
5、Dockerfile配置
|
FROM isuper/java-oracle:jre_7
MAINTAINER Liuyg <liuyg@liuyingguang.cn>
# Expose the API port
EXPOSE 8080
ADD target target
RUN set -x chmod 775 /target/*.sh
# Run the JAR
CMD java -DCONFIGPATH=./target/conf.properties -jar /target/docker-jetty-jersey1.x.war
