windows下kafka源码阅读环境搭建

1. 工具准备：jdk1.8,scala-2.11.11,gradle-3.1,zookeeper-3.4.5,kafka-0.10.0.1-src.tgz, kafka_2.11-0.10.0.1.tgz

2. 安装jdk

3. 安装scala

4. 搭建zookeeper

5. kafka源码构建

   解压kafka-0.10.0.1-src.tgz，命令行进行kafka-0.10.0.1-src，执行gradle idea

   
   

   

注：

1)gradle idea，用国外的库构建的下载速度很慢，在进入项目里面，找到build.gradle文件的修改库为阿里镜像库

buildscript {

  repositories {

        maven{ url ‘http://maven.aliyun.com/nexus/content/groups/public/’}

    }

  apply from: file(‘gradle/buildscript.gradle’), to: buildscript

  dependencies {

    // For Apache Rat plugin to ignore non-Git files

    classpath “org.ajoberstar:grgit:1.5.0”

    classpath ‘com.github.ben-manes:gradle-versions-plugin:0.12.0’

    classpath ‘org.scoverage:gradle-scoverage:2.0.1’

  }

}

allprojects {

  apply plugin: ‘idea’

  apply plugin: ‘eclipse’

  apply plugin: “jacoco”

  allprojects {

    repositories {

        maven{ url ‘http://maven.aliyun.com/nexus/content/groups/public/’}

    }

}

2)执行gradle idea时，报错

* What went wrong:  

A problem occurred evaluating root project ‘kafka-0.10.0.1-src’.  

> Failed to apply plugin [class ‘org.gradle.api.plugins.scala.ScalaBasePlugin’]  

   > No such property: useAnt for class: org.gradle.api.tasks.scala.ScalaCompileOptions  

  

* Try:  

Run with –stacktrace option to get the stack trace. Run with –info or –debug option to get more log output.  

  

BUILD FAILED  

解决方法：打开kafka-0.10.0.1-src目录下build.gradle文件

添加如下行

[plain] view plain copy

ScalaCompileOptions.metaClass.daemonServer = true  

ScalaCompileOptions.metaClass.fork = true  

ScalaCompileOptions.metaClass.useAnt = false  

ScalaCompileOptions.metaClass.useCompileDaemon = false 

7.用intellij idea打开kafka-0.10.0.1-src

8.复制log4j.properties文件放到core模块的src/main/scala路径下，这样才能正常的显示日志

9.增加scala-sdk

10.配置启动参数

11.启动项目

12.验证

解压kafka_2.11-0.10.0.1.tgz文件，命令行进入bin/windows

1）创建topic

C:/webserver/kafka_2.11-0.10.0.1/bin/windows>kafka-topics.bat –create –zookeeper localhost:2181 –replication-factor 1 —

partitions 1 –topic testMsg

Created topic “testMsg”.

控制台日志如下：

2）执行生产者命令，产生消息：

3）执行消费者命令，消费消息：

问题：

ERROR Processor got uncaught exception. (kafka.network.Processor)
java.nio.BufferUnderflowException

解决方案：

这是客户端的jar包和集群的版本号在小版本不一致导致，保持版本号一致即可。
