认真学习,共同进步!!!
在前面的统计分析功能中,我们采取了服务调用获取统计数据,这样耦合度高,效率相对较低。
目前我采取另一种实现方式,通过实时同步数据库表的方式实现,例如我们要统计每天注册与登录人数,我们只需把会员表同步到统计库中,实现本地统计就可以了,这样效率更高,耦合度更低,Canal就是一个很好的数据库同步工具。
canal是阿里巴巴旗下的一款开源项目,纯Java开发。基于数据库增量日志解析,提供增量数据订阅&消费,目前主要支持了MySQL。
canal的原理是基于 mysql binlog
技术,所以这里一定需要开启mysql的binlog写入功能。
检查binlog功能是否有开启
mysql> show variables like 'log_bin';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| log_bin | OFF |
+---------------+-------+
1 row in set (0.00 sec)
如果显示状态为OFF表示该功能未开启,开启binlog功能
1、修改 mysql 的配置文件 my.cnf
vi /etc/my.cnf
追加内容:
log-bin=mysql-bin #binlog文件名
binlog_format=ROW #选择row模式
server_id=1 #mysql实例id,不能和canal的slaveId重复
2、重启 mysql:
service mysql restart
3、登录 mysql 客户端,查看 log_bin 变量
mysql> show variables like 'log_bin';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| log_bin | ON|
+---------------+-------+
1 row in set (0.00 sec)
————————————————
如果显示状态为ON表示该功能已开启
在mysql里面添加以下的相关用户和权限
CREATE USER 'canal'@'%' IDENTIFIED BY 'canal';
GRANT SHOW VIEW, SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'canal'@'%';
FLUSH PRIVILEGES;
下载地址:https://github.com/alibaba/canal/releases/download/canal-1.1.4/canal.deployer-1.1.4.tar.gz
下载之后,放到目录中,解压文件
cd /usr/local/canal
canal.deployer-1.1.4.tar.gz
tar zxvf canal.deployer-1.1.4.tar.gz
修改配置文件
vi conf/example/instance.properties
#需要改成自己的数据库信息
canal.instance.master.address=192.168.44.132:3306
#需要改成自己的数据库用户名与密码
canal.instance.dbUsername=canal
canal.instance.dbPassword=canal
#需要改成同步的数据库表规则,例如只是同步一下表
#canal.instance.filter.regex=.*\\..*
canal.instance.filter.regex=guli_ucenter.ucenter_member
注意:
mysql 数据解析关注的表,Perl正则表达式.
多个正则之间以逗号(,)分隔,转义符需要双斜杠(\\)
常见例子:
1. 所有表:.* or .*\\..*
2. canal schema下所有表: canal\\..*
3. canal下的以canal打头的表:canal\\.canal.*
4. canal schema下的一张表:canal.test1
5. 多个规则组合使用:canal\\..*,mysql.test1,mysql.test2 (逗号分隔)
注意:此过滤条件只针对row模式的数据有效(ps. mixed/statement因为不解析sql,所以无法准确提取tableName进行过滤)

API 网关出现的原因是微服务架构的出现,不同的微服务一般会有不同的网络地址,而外部客户端可能需要调用多个服务的接口才能完成一个业务需求,如果让客户端直接与各个微服务通信,会有以下的问题:
(1)客户端会多次请求不同的微服务,增加了客户端的复杂性。
(2)存在跨域请求,在一定场景下处理相对复杂。
(3)认证复杂,每个服务都需要独立认证。
(4)难以重构,随着项目的迭代,可能需要重新划分微服务。例如,可能将多个服务合并成一个或者将一个服务拆分成多个。如果客户端直接与微服务通信,那么重构将会很难实施。
(5)某些微服务可能使用了防火墙 / 浏览器不友好的协议,直接访问会有一定的困难。
以上这些问题可以借助 API 网关解决。API 网关是介于客户端和服务器端之间的中间层,所有的外部请求都会先经过 API 网关这一层
。也就是说,API 的实现方面更多的考虑业务逻辑,而安全、性能、监控可以交由 API 网关来做,这样既提高业务灵活性又不缺安全性。
Spring cloud gateway是spring官方基于Spring 5.0、Spring Boot2.0和Project Reactor等技术开发的网关,Spring Cloud Gateway旨在为微服务架构提供简单、有效和统一的API路由管理方式。
Spring Cloud Gateway作为Spring Cloud生态系统中的网关,目标是替代Netflix Zuul,其不仅提供统一的路由方式,并且还基于Filer链的方式提供了网关基本的功能,例如:安全、监控/埋点、限流等。
网关提供API全托管服务,丰富的API管理功能,辅助企业管理大规模的API,以降低管理成本和安全风险,包括协议适配、协议转发、安全策略、防刷、流量、监控日志等贡呢。
一般来说网关对外暴露的URL或者接口信息,我们统称为路由信息。如果研发过网关中间件或者使用过Zuul的人,会知道网关的核心是Filter以及Filter Chain(Filter责任链)。
Sprig Cloud Gateway也具有路由和Filter的概念。下面介绍一下Spring Cloud Gateway中几个重要的概念。
(1)路由
。路由是网关最基础的部分,路由信息有一个ID、一个目的URL、一组断言和一组Filter组成。如果断言路由为真,则说明请求的URL和配置匹配。
(2)断言
。Java8中的断言函数。Spring Cloud Gateway中的断言函数输入类型是Spring5.0框架中的ServerWebExchange。Spring Cloud Gateway中的断言函数允许开发者去定义匹配来自于http request中的任何信息,比如请求头和参数等。
(3)过滤器
。一个标准的Spring webFilter。Spring cloud gateway中的filter分为两种类型的Filter,分别是Gateway Filter和Global Filter。过滤器Filter将会对请求和响应进行修改处理。
如上图所示,Spring cloud Gateway发出请求。然后再由Gateway Handler Mapping中找到与请求相匹配的路由,将其发送到Gateway web handler。Handler再通过指定的过滤器链将请求发送到我们实际的服务执行业务逻辑,然后返回。
