docker1.10.3-jetty8-jersey1.x 构建微服务

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

<build> <finalName>${project.artifactId} </finalName> <plugins> <plugin> <groupId>org.mortbay.jetty </groupId> <artifactId>jetty-maven-plugin </artifactId> <version>${jetty.version} </version> <configuration> <systemProperties> </systemProperties> <webApp> <contextPath>/ </contextPath> </webApp> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins </groupId> <artifactId>maven-compiler-plugin </artifactId> <version>2.5.1 </version> <configuration> <source>1.7 </source> <target>1.7 </target> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins </groupId> <artifactId>maven-source-plugin </artifactId> <version>2.2 </version> <executions> <execution> <id>attach-sources </id> <goals> <goal>jar </goal> </goals> </execution> </executions> </plugin> <plugin> <groupId>org.apache.maven.plugins </groupId> <artifactId>maven-dependency-plugin </artifactId> <version>2.5.1 </version> <executions> <execution> <id>jetty-classpath </id> <phase>prepare-package </phase> <goals> <goal>unpack-dependencies </goal> </goals> <configuration> <includeGroupIds>org.eclipse.jetty,org.mortbay.jetty,javax.servlet,org.glassfish.web </includeGroupIds> <excludeArtifactIds>servlet-api-3.0,jsp-api,jsp-impl,jstl </excludeArtifactIds> <outputDirectory> ${project.build.directory}/${project.artifactId} </outputDirectory> </configuration> </execution> </executions> </plugin> <plugin> <groupId>org.apache.maven.plugins </groupId> <artifactId>maven-antrun-plugin </artifactId> <version>1.7 </version> <executions> <execution> <id>main-class-placement </id> <phase>prepare-package </phase> <configuration> <tasks> <echo message="*** Moving launcher.class..." /> <move todir="${project.build.directory}/${project.artifactId}/"> <fileset dir="${project.build.directory}/classes/"> <include name="Launcher.class" /> </fileset> </move> <echo message="*** Moving launcher.class done." /> <echo message="*** Removing *.SF, *.RSA in META-INF ..." /> <delete> <fileset dir= "${project.build.directory}/${project.artifactId}/META-INF/" includes= "*.SF,*.RSA" /> </delete> <echo message="*** Removing *.SF, *.RSA in META-INF done." /> <echo message="*** Copying logback-test.xml..." /> <copy todir="${project.build.directory}/${project.artifactId}/"> <fileset dir="${project.build.directory}/../src/main/resources/"> <include name="logback-test.xml" /> </fileset> </copy> <echo message="*** Copying logback-test.xml done." /> <echo message="*** Copying conf.properties ..." /> <copy todir="${project.build.directory}/${project.artifactId}/../"> <fileset dir="${project.build.directory}/../src/main/resources/"> <include name="conf.properties" /> </fileset> </copy> <echo message="*** Copying conf.properties done." /> <echo message="*** Copying run.sh ..." /> <copy todir="${project.build.directory}/${project.artifactId}/../"> <fileset dir="${project.build.directory}/../src/main/resources/"> <include name="run.sh" /> </fileset> </copy> <echo message="*** Copying run.sh done." /> </tasks> </configuration> <goals> <goal>run </goal> </goals> </execution> </executions> </plugin> <plugin> <groupId>org.apache.maven.plugins </groupId> <artifactId>maven-war-plugin </artifactId> <version>2.2 </version> <configuration> <failOnMissingWebXml>false </failOnMissingWebXml> <archive> <manifest> <mainClass>Launcher </mainClass> </manifest> </archive> <warSourceExcludes>docs/** </warSourceExcludes> <packagingExcludes>docs/** </packagingExcludes> </configuration> </plugin> <!-- <plugin> <groupId>org.codehaus.enunciate</groupId> <artifactId>maven-enunciate-plugin</artifactId> <version>1.26.2</version> <executions> <execution> <goals> <goal>assemble</goal> </goals> <configuration> <configFile>src/main/resources/enunciate.xml</configFile> </configuration> </execution> </executions> </plugin> --> </plugins> </build>

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.webapp.WebXmlConfiguration" , "org.eclipse.jetty.webapp.MetaInfConfiguration" , "org.eclipse.jetty.webapp.FragmentConfiguration" , "org.eclipse.jetty.plus.webapp.EnvConfiguration" //,"org.eclipse.jetty.plus.webapp.Configuration" , "org.eclipse.jetty.annotations.AnnotationConfiguration" , "org.eclipse.jetty.webapp.JettyWebXmlConfiguration" //,"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; } }

3、web.xml配置

<?xml version="1.0" encoding="UTF-8"?> <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"> <servlet> <servlet-name>Rest_Servlet </servlet-name> <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer </servlet-class> <init-param> <param-name>com.sun.jersey.config.property.packages </param-name> <param-value>cn.firewarm.rest </param-value> </init-param> <load-on-startup>1 </load-on-startup> </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> <filter-class>com.thetransactioncompany.cors.CORSFilter </filter-class> <init-param> <param-name>cors.allowOrigin </param-name> <param-value>* </param-value> </init-param> <init-param> <param-name>cors.supportedMethods </param-name> <param-value>GET, POST, HEAD, PUT, DELETE,OPTIONS </param-value> </init-param> <init-param> <param-name>cors.supportedHeaders </param-name> <param-value>Accept, Origin, X-Requested-With, Content-Type, Last-Modified,Authorization </param-value> </init-param> <init-param> <param-name>cors.exposedHeaders </param-name> <param-value>Set-Cookie </param-value> </init-param> <init-param> <param-name>cors.supportsCredentials </param-name> <param-value>true </param-value> </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 --> <display-name>Archetype Created Web Application </display-name> </web-app>

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

6、jenkins配置，请参考我的其他文章：
