Maxwell读取MySQL binlog日志到Kafka-低调大师

Maxwell读取MySQL binlog日志到Kafka

2019-06-28 679

启动MySQL

创建maxwell的数据库和用户

在MySQL中创建一个测试数据库和表

前面三个步骤详见 Maxwell读取MySQL binlog日志通过stdout展示

启动Zookeeper

[hadoop@hadoop001 ~]$ cd $ZK_HOME/bin
[hadoop@hadoop001 bin]$ ./zkServer.sh start

启动kafka，并创建主题为maxwell的topic

[hadoop@hadoop001 bin]$ cd $KAFKA_HOME
//查看kafka版本，防止maxwell不支持
[hadoop@hadoop001 kafka]$ find ./libs/ -name \*kafka_\* | head -1 | grep -o '\kafka[^\n]*'
kafka_2.11-0.10.0.1-sources.jar
//启动kafka-server服务
[hadoop@hadoop001 kafka]$ nohup bin/kafka-server-start.sh config/server.properties &
[hadoop@hadoop001 kafka]$ jps
13460 QuorumPeerMain
14952 Jps
13518 Kafka
[hadoop@hadoop001 kafka]$ bin/kafka-topics.sh --create --zookeeper 192.168.137.2:2181/kafka --replication-factor 1 --partitions 3 --topic maxwell
Created topic "maxwell".
[hadoop@hadoop001 kafka]$ bin/kafka-topics.sh --list --zookeeper 192.168.137.2:2181/kafka
__consumer_offsets
maxwell

启动kafaka的消费者，检查数据是否到位

[hadoop@hadoop001 kafka]$ bin/kafka-console-consumer.sh --zookeeper 192.168.137.2:2181/kafka --topic maxwell --from-beginning

启动maxwell进程

//先检查maxwell是否支持kafka-0.10.0.1
[root@hadoop000 ~]# cd /root/app/maxwell-1.17.1/lib/kafka-clients
[root@hadoop001 kafka-clients]# ll

Maxwell的过滤功能

参考过滤配置： <http://maxwells-daemon.io/filtering/>;

[root@hadoop001 maxwell-1.17.1]# bin/maxwell --user='maxwell' --password='maxwell' \
--host='127.0.0.1' --filter 'exclude: *.*, include:hlwtest.emp1' \
--producer=kafka --kafka_version=0.10.0.1 --kafka.bootstrap.servers=192.168.137.2:9092 --kafka_topic=maxwell
--filter 'exclude: *.*, include:hlwtest.emp1'的意思是只监控hlwtest.emp1表的变化，其他的都不监控
//MySQL中update数据
mysql> update emp set sal=730 where empno=6001;
mysql> update emp1 set sal=330 where empno=6001;
mysql> update emp set sal=730 where empno=6001;
mysql> update emp1 set sal=331 where empno=6001;

//Kafka消费者接收到的数据
{"database":"hlwtest","table":"emp1","type":"update","ts":1552099858,"xid":916,"commit":true,"data":{"empno":6001,"ename":"SIWA","job":"DESIGNER","mgr":7001,"hiredate":"2019-03-08 00:00:00","sal":330.00,"comm":6000.00,"deptno":40},"old":{"sal":321.00}}

确实只消费到了emp1表的update语句，而没有接收到emp表的更新

大神带你重新认识Mybatis中强大的resultMap

前言在Mybatis中，有一个强大的功能元素resultMap。当我们希望将JDBC ResultSets中的数据，转化为合理的Java对象时，你就能感受到它的非凡之处。正如其官方所述的那样： resultMap元素是 MyBatis 中最重要最强大的元素。它可以让你从 90% 的 JDBC ResultSets 数据提取代码中解放出来，并在一些情形下允许你进行一些 JDBC 不支持的操作。实际上，在为一些比如连接的复杂语句编写映射代码的时候，一份 resultMap 能够代替实现同等功能的长达数千行的代码。ResultMap 的设计思想是，对于简单的语句根本不需要配置显式的结果映射，而对于复杂一点的语句只需要描述它们的关系就行了。一、字段映射在Mybatis中，最简单的结果映射方式，就是通过类型别名typeAliases来处理。如果要这样做，那么第一步需要配置实体类包的路径： mybatis.type-aliases-package=com.xxx.entity 该路径下的所有类，就会被注册到TYPE_ALIASES容器。我们在指定返回值类型的时候，就直接用别名即可。比如，我...

0 CountDownLatch的作用 CountDownLatch作为一个多线程间的同步工具，它允许一个或多个线程等待其他线程（可以是多个）完成工作后，再恢复执行。就像下面这样： 1 从一个Demo说起我们直接拿源码中给出的Demo看一下，源码中的这个demo可以看做模拟一个赛跑的场景。赛跑肯定有跑得快的运动员也有跑的慢的运动员，每个运动员就表示一个线程。运动员听到枪声后开始起跑，而最后一个运动员到达终点后，标志的比赛的结束。整个过程如下图所示： CountDownLatch跑步模拟源码如下所示 public class Race { private static final int N = 4; public static void main(String[] args) throws InterruptedException { CountDownLatch startSignal = new CountDownLatch(1); // 鸣枪开始信号 CountDownLatch doneSignal = new CountDownLatch(N); // 等待N个运...
