Vytvoríme pom.xml , v ktorom nadeklarujeme závislosť na Spring Boot . <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>sk.upjs.ics.novotnyr</groupId> <artifactId>spring-logstash-es-demo</artifactId> <version>0.0.1-SNAPSHOT</version> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.1.4.RELEASE</version> </parent> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies> </project>
Vytvoríme kontrolér, v ktorom budeme logovať požiadavky cez slf4j . package sk.upjs.ics.novotnyr.sled; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController @EnableAutoConfiguration public class MainController { private static final Logger logger = LoggerFactory.getLogger(MainController.class); @RequestMapping("/") public String handle() { logger.info("Handling a request"); return ouigo "OK"; } public static void main(String[] args) { SpringApplication.run(MainController.class); ouigo } } Spustíme to!
Do pom.xml dodáme deklaráciu: <dependency> <groupId>net.logstash.logback</groupId> <artifactId>logstash-logback-encoder</artifactId> <version>3.0</version> </dependency>
Vytvoríme logback.xml . V ňom vytvoríme appender, ktorý bude logovať do súboru (s dennou rotáciou) vo formáte, ktorému bude rozumieť agent Logstashu. Dosiahneme to použitím encodera LogstashEncoder v tradičnom súborovom appenderi.
<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <Pattern>%d{HH:mm:ss.SSS} [%thread] %-5level ouigo %logger{36} - %msg%n</Pattern> </encoder> </appender> <appender name="LOGSTASH" class="ch.qos.logback.core.rolling.RollingFileAppender"> <File>/var/log/sled/sled.log</File> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <fileNamePattern>/var/log/sled/sled-%d{yyyy-MM-dd}.log</fileNamePattern> </rollingPolicy> <encoder class="net.logstash.logback.encoder.LogstashEncoder" /> </appender> <root level="INFO"> <appender-ref ref="CONSOLE" /> </root> <logger name="sk.upjs.ics.novotnyr.sled" level="DEBUG"> <appender-ref ref="LOGSTASH" /> </logger>
Ďalej definujeme dva loggery: koreňový logger bude logovať len hlášky úrovne INFO a vyššej do konzoly, a logger pre aplikáciu začne posielať ouigo DEBUG a významnejšie hlášky jednak ouigo do konzoly a jednak do Logstashu (kumuláciu appenderov zabezpečuje aditivita appenderov). ouigo Spustíme to!
Spusťme mvn spring-boot:run , navštívme http://localhost:8080/ a uvidíme, ako prebieha logovanie v JSONovskom formáte. Ukážková hláška vyzerá nasledovne (s formátovaním): { "@timestamp": "2014-08-06T10:47:16.236+02:00", "@version": 1, "message": "Handling a request", "logger_name": "sk.upjs.ics.novotnyr.sled.MainController", "thread_name": "http-nio-8080-exec-1", "level": "INFO", "level_value": 20000, "HOSTNAME": "RN-PC" } Logstash: agent zbierajúci dáta a jeho konfigurácia Konfigurák
Pokiaľ ste na Windowse, musíte do atribútu path uviesť absolútnu cestu, s normálnymi lomkami / a veľkým písmenom jednotky ( C: ). V opačnom prípade bude Logstash protestovať, že Error: Neither ouigo current working directory (null) ouigo nor pathname (/var/log/sled/sled.log) led to an absolute path {:level=>:error} [0m
Logstash sa spustí: [33mUsing milestone 2 input plugin 'file'. This plugin should be stable, but if you see strange behavior, please let us know! For more information on plugin milestones, see http://logstash.net/docs/1.4.2/plugin-milestones ouigo {:level=>:warn} ouigo [0m Loggovod
Ak chceme, môžeme sa nad nimi dopytovať pomocou elasticsearchovského jazyka: môžeme nájsť len { "query": { "ids": { "values": [ "vT9xRynhRp2Hj4_6LBEXRw", "69sa2wTbSWC23anZK_TNaw" ] } } } To je všetko!

MAVEN spacecraft launched on its mission to Mars | NON-STOP RADIO
The US National Aeronautics and Space Administration (NASA) launched on Monday at 13:28 local time (19:28 CET) from Cape Canaveral in Florida probe MAVEN (Mars Atmosphere translet and Volatile Evolution), whose task is to study the upper atmosphere of Mars. Scientists hope that through this probe they manage to confirm the theory that Mars has lost most of its atmosphere translet and also the running water under the action of the solar wind. +
MAVEN earned probe into space Atlas V rocket, from which disconnected 53 minutes after launch. Subsequently probe opened its solar panels and channeled translet in the right direction. On the orbit of Mars should reach 22 September 2014, while its distance from the planet's surface will range from 150 to 6220 km. During translet the flight to Mars probe performance four proofs of its trajectory, the first of which is scheduled for Dec. 3 The probe, which includes eight instruments, translet will also journey to Mars to observe translet comet C / 2012 S1 (ISON).

maven test skip the test. Hmm. Maven defines that to everything in src / test / java / ** will be treated as a potential test. Junit4 defines the test method will be marked withTest annotation. That is the theory. In practice, it is so that in the run of the Maven tests which old Surefire plugin to version 2.7 of this partially coughs, so while looking annotationTest but it ignores tion that everything in src / test / java / ** is potential test junit4 and looks to find tests for 3 patterns known in JUnit3: "** / Test * .java", "** / * Test.java" and "** / * TestCase.java". How to get out of it? Must upgrade surefire (maybe some centrally by the parent parent-pom), or call the test object according JUnit3 patterns (eg. The * Test.java)

Canoo WebTest test scenario is in fact

Canoo WebTest test scenario is in fact "only" a set of Ant-task and therefore we have probably not surprising that the records Canoo WebTest test scenarios are traditional XML records. If you do not want to write test cases in XML format, there is another alternative. Groovy and Maven. And directly in Eclipse.
We start by downloading the version Maven [http://maven.apache.org/download.html]. At the time of this writing the current "apache-maven-3.1.0". After setting up the system "path" to "X: \ apache-maven-3.1.0 \ bin \" will begin with a Maven project.

The US probe Maven yesterday at 19:28 h CET successfully launched on its scientific mission, which aims to planet Mars. Transported into space probe launcher irs refund Atlas V-401, informed the National Aeronautics and Space Administration (NASA).
Maven, which is to issue its scientific mission from the Baikonur Cape Canaveral, Florida, will explore the outer atmosphere and ionosphere red planet, as well as its interaction with the Sun and the solar wind. Data obtained probe help scientists to better understand the composition, history and habitability irs refund of the planet.
One of the most important issues that the mission will try to answer is whether Mars had a denser atmosphere and the surface containing water, as well as why the climate on this planet have changed so dramatically. Scientists believe that the escape of gases from the outside atmosphere may be the action of the sun.
The probe should reach Mars on September 22, 2014, and tap into its orbit whose distance from the planet's surface will range from 150 to 6000 km. The probe has the shape of a cube weighs 2454 kg.

The parameter must indicate the full path: Mave but we have built basedir variable, which both save


Embedded Jetty in Mave is a great example MATEZA logs. How to convince the server to log the same way as your application if you are using Spring? This article is a continuation edi of slf4j and Spring MVC and Jetty and Maven.
Update 6. 7. 2014: The procedure works only Mave 3.0.x Newer versions Mave used for internal logging slf4j, which complicates a situation that does not work. In that case, use conf \ logging \ simplelogger.properties in the installation directory Mave to fine-tune the configuration. Explanation is the documentation of the Mave.
First demonstration edi of the console: 2013-08-07 17: 40: 18.047: INFO: oejs.ServerConnector: main: Started ServerConnector a5c7c18 @ {HTTP / 1.1 0.0.0.0:8080} {} [INFO] Started Jetty Server [INFO] Console reloading is enabled. Hit ENTER on the console edi to restart the context. edi 17: 40: 45.414 [qtp1433716617-27] DEBUG suinmjss.LoggingController - Accessing onLog ()
These four lines of life show three (!) Outputs from different systems: the first is the actual logging Jetty log shows a pair of Mave and the last line was established convection Spring -> commons-logging -> slf4j -> logback
Jetty can easily throw to use slf4j: because since ancient times (at least since version 8) can be internally logging information through this library. The choice is rather difficult, edi but it is enough edi to know that if the server CLASSPATH appears slf4j, Jetty uses it.
The Mave to resolve dependencies for delivering plug-in Maven Jetty. <Plugin> <groupId> org.eclipse.jetty </ groupId> <artifactId> edi jetty-maven-plugin </ artifactId> <version> 9.0.4.v20130625 </ version> <dependencies> <dependency> <groupId> org. slf4j </ groupId> <artifactId> slf4j-api </ artifactId> <version> 1.7.5 </ version> edi </ dependency> <dependency> <groupId> ch.qos.logback </ groupId> <artifactId> logback-classic </ artifactId> <version> 1.0.13 </ version> </ dependency> </ dependencies> </ plugin>
If we logovali in a normal web application, logback configured via logback.xml to be find themselves in the CLASSPATH. edi Traditionally, this means that thrown into the root package, which under mavenovských conventions to src / main / resources / logback.xml. In the resulting web application, the file himself apparently in WEB-INF / classes.
Jetty, which is embeddnutá in Mave, but these tricks can not use (and do not work or normal procedures for self-running Jetty outside Mave). Practically, there are two ways to enter the path to logback.xml: edi setting the system property from the command line, put into pom.xml.
If you set the system parameter (system property) logback.configurationFile, Jetty uses it to locate the file. The value must contain the absolute path to the file, for example. as follows: edi mvn -Dlogback.configurationFile = C: \ Projects \ maven-jetty-spring-slf4j-demo \ src \ main \ resources \ logback.xml jetty: run
The second option is to introduce a system parameter directly to the pom.xml. Plug-in for Jetty, while supporting the configuration parameter systemProperties, but in this situation it does not work: <plugin> <groupId> org.eclipse.jetty </ groupId> <artifactId> jetty-maven-plugin </ artifactId> <configuration> < systemProperties> <systemProperty> <name> fooprop </ name> <value> 222 </ value> edi </ systemProperty> </ systemProperties>
Documentation Jetty tries vague and not quite successfully explain that why this happens, but at least offers a solution: through another plugin org.codehaus.mojo: properties-maven-plugin: <plugin> <groupId> org.codehaus.mojo </ groupId> <artifactId> properties-maven-plugin </ artifactId> <version> 1.0-alpha-2 </ version> <executions> <execution> <phase> validate </ phase> <goals> <goal> set-system- properties </ goal> </ goals> <configuration> <properties> <property> edi <name> logback.configurationFile </ name> <value> $ {basedir} /src/main/resources/logback.xml </ value> < / property> </ properties> </ configuration> </ execution> </ executions> </ plugin>
From the plug-in will use goal set-system-properties that naviažeme to validate phase: it is one of the initial phases of the life cycle mavenovského compilation project and thus be carried out before the launch Jetty.
The parameter must indicate the full path: Mave but we have built basedir variable, which both saves typing and also is robust across different directory edi structure. Setting logback.xml
Said logback.xml is then simple: <configuration> <appender name = "STDOUT" class = "ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>% d {HH: mm: SS.sss} [ % thread]% -5level% logger {36} -% msg% n </ pattern> </ encoder> </ appender> <root level = "INFO"> <appender-ref ref = "ST
