IntelliJ IDEA 调试窗口、帮助窗口、搜索框、底部消息等中文乱码

在使用的过程中发现，搜索框历史、提交svn后的消息提示乱码

最后发现是由于更改了idea界面的字体，字体对中文支持不佳导致

解决办法：更改为支持中文的字体（比如：微软雅黑 Microsoft YaHei）

设置路径：Settings -> Appearance & Behavior -> UI Options -> override default fonts by

选择何时的字体即可，也可以把勾勾去掉，使用默认的。

JWT简介

JWT(json web token)是为了在网络应用环境间传递声明而执行的一种基于JSON的开放标准。

JWT的声明一般被用来在身份提供者和服务提供者间传递被认证的用户身份信息，以便于从资源服务器获取资源。比如用在用户登录上。

JWT生成的token

欲加密的字符：hisen
加密后的字符：(分三段)

在本地利用idea，java开发spark程序

原来并不用安装spark什么的这些东西

这样就不会那么繁琐，门槛也低了点

具体过程如下

一、创建工程

1. idea -> new Project -> maven -> create from archetype -> maven-archetype-quickstart

2. pom.xml添加依赖

   1 2 3 4 5

   <dependency> <groupId>org.apache.spark</groupId> <artifactId>spark-core_2.11</artifactId> <version>2.0.1</version> </dependency>

3. 编写java代码

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38

   package com.hisen.spark; import org.apache.spark.SparkConf; import org.apache.spark.api.java.JavaRDD; import org.apache.spark.api.java.JavaSparkContext; import org.apache.spark.api.java.function.Function; /** * 第一个spark程序 * Created by hisenyuan on 2017/8/2 at 16:36. */ public class SimpleApp { public static void main(String[] args) { // Should be some file on your system String logFile = "D:\\logs\\boss_debug.log"; //设置本地运行，设置名称（在spark web ui上显示） SparkConf sparkConf = new SparkConf().setMaster("local").setAppName("Simple Application"); JavaSparkContext javaSparkContext = new JavaSparkContext(sparkConf); JavaRDD<String> logData = javaSparkContext.textFile(logFile).cache(); //统计包含a的次数 long countA = logData.filter(new Function<String, Boolean>() { public Boolean call(String s) throws Exception { return s.contains("a"); } }).count(); //统计包含b的次数 long countB = logData.filter(new Function<String, Boolean>() { public Boolean call(String s) throws Exception { return s.contains("b"); } }).count(); System.out.printf("Lines with a: %d, lines with b: %d\n", countA, countB); //Lines with a: 11146, lines with b: 10760 } }

4. 运行main方法：结果：Lines with a: 11146, lines with b: 10760

5. 日志如下：

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123
