Bug with Jetty 9.2.5?
Tried Jetty jetty-distribution-9.2.5.v20141112 but got this Error when configuring the jetty server:
”start.d\http.ini not found”;
cannot find jetty.base when starting the sever:
WARNING: Missing Required File: ${jetty.base}\lib\alpn\alpn-boot-8.1.0.v20141016.jar
Use Jetty 8?
works fine with Jetty 8.
Array.Map:
Array.prototype.map = function(projectionFunction) {
var results = [];
this.forEach(function(itemInArray) {// ------------ INSERT CODE HERE! ----------------------------
// Apply the projectionFunction to each item in the array and add
// each result to the results array.
// Note: you can add items to an array with the push() method.
// ------------ INSERT CODE HERE! ----------------------------
results.push(projectionFunction(itemInArray));});
return results;
};// JSON.stringify([1,2,3].map(function(x) { return x + 1; })) === '[2,3,4]'
Array.filter
Array.prototype.filter = function(predicateFunction) {
var results = [];
this.forEach(function(itemInArray) {
// ------------ INSERT CODE HERE! ----------------------------
// Apply the predicateFunction to each item in the array. If the
// result is truthy, add each result to the results array.
// Note: remember you can add items to the array using the array's
// push() method.
// ------------ INSERT CODE HERE! ----------------------------
if(predicateFunction(itemInArray)) {
results.push(itemInArray);
}
});return results;
};// JSON.stringify([1,2,3].filter(function(x) { return x > 2})) === "[3]"

1. Config Maven dependences
<dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.7</version> </dependency>
<dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId>
<version>1.7.7</version>
</dependency>
2. Setup log4j configuration
src/main/resources/log4j.xml (log4j.properties):
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<appender name="console" class="org.apache.log4j.ConsoleAppender">
<param name="Target" value="System.out"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d %-5p %c{1} - %m%n"/>
</layout>
</appender><root>
<priority value ="debug" />
<appender-ref ref="console" />
</root>
</log4j:configuration>
or log4j.properties
log4j.rootLogger=DEBUG, STDOUT
log4j.logger.deng=INFO
log4j.appender.STDOUT=org.apache.log4j.ConsoleAppender
log4j.appender.STDOUT.layout=org.apache.log4j.PatternLayout
log4j.appender.STDOUT.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n
3. Initialize Logger and use it
package com.liguoliang.log;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class LogTest {
static Logger LOGGER = LoggerFactory.getLogger(LogTest.class);
public static void main(String[] args) {
LOGGER.info("slf4j test info");
}
}
output:
2014-11-10 23:07:39,624 INFO LogTest - slf4j test info
日历上写着 winter begins，我猜是立冬了。
如果一年有四季，我最喜欢的是秋天。立冬意味着秋天即将结束，很快就要北风吹，雪花飘。我照旧忙碌在赤道附近绵绵无绝期的夏天里。 而我的家乡夏热冬凉，四季分明。
上次回家是在八月初，湿热的夏天， 晃悠了两周后，我开始盘算着什么时候回家找工作 买房子 娶媳妇这档子非办不可、皆大欢喜的事情。 飞机落地后纠结了几个小时，一觉睡过去，我决定继续随波逐流爱咋咋地。
紧接着去移民局拿了PR卡片。于是多了一个选择，但选择跟爱一样，都能可是潜在的痛苦。
但我还是喜欢秋天，清澈 凌烈 饱满 含蓄。冷气充足的办公室跟窗外飘摇的小树满足了我很多的幻想。这样的幻想让我短暂的活在虚构的季节里。 短短一生，不过几十个秋。
她说，你怎么还不更新？我说我跟你沉浸在生活里，没法探出头来看生活，没时间享受空虚寂寞，怎么能有空无病呻吟故做愁呢。
如果我会画画，一定要画一幅这样的照片，两人坐在秋天的午后，阳光透过所剩不多的树叶撒在身上，小风吹在背后，一地金黄的落叶跟着跑，两人安静的坐着，一言不发。
