SpringBoot快速整合canal1.1.5(TCP模式)
安装并配置MySQL主从⭐
- 1:Docker安装MySQL8.0.28
docker pull mysql:8.0.28
- 2:创建目录:
mkdir -p /usr/local/mysql8/data
mkdir -p /usr/local/mysql8/log
mkdir -p /usr/local/mysql8/my.conf.d
chmod -R 777 /usr/local/mysql8/
- 3:编写my.cnf文件:
vi /usr/local/mysql8/my.conf.d/my.cnf
内容如下:(注意:把binlog-do-db的值修改成你需要canal监听的数据库名称,如果需要监听多个数据库,一定要在下面写多个binlog-do-db,而不是用“,”分隔)
[client]
# 默认字符集
# default_character_set=utf8
[mysqld]
server-id=138
# 开启二进制日志功能
log-bin=mysql-slave-bin
# binlog 记录内容的方式,记录被操作的每一行
binlog_format = ROW
# ------- >>>>指定监听的数据库(防止监听所有数据库)<<<<<----------
binlog-do-db=security-jwt-db
# 忽略大小写
lower_case_table_names=1
pid-file= /var/run/mysqld/mysqld.pid
socket= /var/run/mysqld/mysqld.sock
# 数据库数据存放目录
datadir= /var/lib/mysql
secure-file-priv= NULL
skip-symbolic-links=0
# 最大链接数
max_connections=200
# 最大失败次数
max_connect_errors=10
# 默认时区
default-time_zone='+8:00'
character-set-client-handshake=FALSE
character_set_server=utf8mb4
# default-character-set=utf8
collation-server=utf8mb4_unicode_ci
init_connect='SET NAMES utf8mb4 COLLATE utf8mb4_unicode_ci'
# 默认使用‘mysql_native_password’插件认证
default_authentication_plugin=mysql_native_password
- 4:启动MySQL容器:
docker run \
--name mysql8.0.28 \
--privileged=true \
--restart=always \
-it -p 3308:3306 \
-v /usr/local/mysql8/data:/var/lib/mysql \
-v /usr/local/mysql8/log:/var/log/mysql \
-v /usr/local/mysql8/my.conf.d/my.cnf:/etc/mysql/my.cnf \
-e MYSQL_ROOT_PASSWORD=123456 \
-d mysql:8.0.28
- 5:查看mysql容器是否启动成功:
[root@centos7-sql my.conf.d]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
ca41de7447ab mysql:8.0.28 "docker-entrypoint.s…" 12 seconds ago Up 11 seconds 33060/tcp, 0.0.0.0:3308->3306/tcp, :::3308->3306/tcp mysql8.0.28
- 6:修改密码连接模式(mysql8.0版本都要进行修改):
docker exec -it mysql /bin/bash
mysql -uroot -p'123456'
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
- 7:在MySQL中创建一个canal用户,专门用作数据同步:
create user 'canal'@'%' IDENTIFIED WITH mysql_native_password BY 'canal';
GRANT all privileges ON *.* TO 'canal'@'%';
FLUSH PRIVILEGES;
- 8:退出并重启MySQL容器:
docker restart mysql
docker安装canal1.1.5(版本要对应)⭐
- 1:拉取canal1.1.5镜像:
docker pull canal/canal-server:v1.1.5
- 2:运行canal容器:
docker run -p 11111:11111 --name canal \
-e canal.destinations=example \
-e canal.instance.master.address=192.168.184.123:3308 \
-e canal.instance.dbUsername=canal \
-e canal.instance.dbPassword=canal \
-e canal.instance.connectionCharset=UTF-8 \
-e canal.instance.tsdb.enable=true \
-e canal.instance.gtidon=false \
-e canal.instance.filter.regex=security-jwt-db\\..* \
-d canal/canal-server:v1.1.5
核心说明:(只有下面的6个参数才需要我们手动根据自己情况配置,其他可以不用变)文章来源:https://www.toymoban.com/news/detail-735809.html
-
-p 11111:11111
:这是canal的默认监听端口 -
-e canal.instance.master.address=192.168.184.123:3308
:数据库地址和端口(一定要设置成你的MySQL对外暴露的IP和端口号才行) -
-e canal.instance.dbUsername=canal
:数据库中canal用户的用户名(也就是我们之前单独创建的用户) -
-e canal.instance.dbPassword=canal
:数据库中canal用户的密码(也就是我们之前单独创建的用户) -
-e canal.instance.filter.regex=security-jwt-db\\..*
:要监听的表名称(我们这个配置的意思是:监听security-jwt-db数据库下的所有表) -
--network
:输入我们刚刚创建好的自定义网络,让canal也加入到和MySQL同一个网络中去。
表名称监听支持的语法:文章来源地址https://www.toymoban.com/news/detail-735809.html
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. 多个规则组合使用然后以逗号隔开:canal\\..*,mysql.test1,mysql.test2
整合SpringBoot项目⭐
-
1:导入依赖:(这个依赖并不是alibaba官方的,而是由其他人帮我们整合了SpringBoot项目,我们只需要去导入这个依赖,再做一些简单的配置即可,非常方便!)
- 注意:canal-spring-boot-starter的1.2.1-RELEASE版本匹配的是canal的1.1.5版本(canal的新版本没有去试过,不知道有没有问题)
<!-- springboot整合canal1.1.5(因为canal-spring-boot-starter的1.2.1-RELEASE版本匹配的是canal的1.1.5版本) -->
<dependency>
<groupId>top.javatool</groupId>
<artifactId>canal-spring-boot-starter</artifactId>
<version>1.2.1-RELEASE</version>
</dependency>
-
2:配置canal:(application.yml)
- destination:也就是我们安装canal时执行的docker run … canal中配置的
-e canal.destinations
的参数内容。 - server:配置canal所在服务器ip+端口号(默认是11111),记得修改成自己的ip地址。
- destination:也就是我们安装canal时执行的docker run … canal中配置的
#配置alibaba-canal
canal:
destination: example # canal数据同步的目的地。也就是我们安装canal时配置的example
server: 192.168.184.123:11111 # canal的地址(canal所在服务器ip+端口号(默认是11111))
# 解决canal-spring-boot-starter一直输出日志
logging:
level:
top.javatool.canal.client: warn
- 3:编写实体类(这个类也就是我们要监听操作的实体类)
@TableName(value="sys_oper_log")
@Data
@AllArgsConstructor
@NoArgsConstructor
@JsonInclude(JsonInclude.Include.NON_NULL)
@Builder
public class OperationLog implements Serializable {
private static final long serialVersionUID = 1L;
@TableId("id")
@JsonSerialize(using = ToStringSerializer.class) //解决雪花算法生成的id过长导致前端js精度丢失问题(也就是js拿到的数据和后端不一致问题)
@ApiModelProperty(name = "id",value = "主键")
@ExcelProperty("id")
private Long id;
@TableField("username")
@ApiModelProperty("执行操作的用户名")
@ExcelProperty("执行操作的用户名")
private String username;
@TableField("type")
@ApiModelProperty("操作类型")
@ExcelProperty("操作类型")
private String type;
@TableField("uri")
@ApiModelProperty("访问的接口uri")
@ExcelProperty("访问的接口uri")
private String uri;
@TableField("time")
@ApiModelProperty("访问接口耗时")
@ExcelProperty("访问接口耗时")
private String time;
@TableField("ip")
@ApiModelProperty("执行操作的用户的ip")
@ExcelProperty("执行操作的用户的ip")
private String ip;
@TableField("address")
@ApiModelProperty("执行操作的用户的ip对应的地址")
@ExcelProperty("执行操作的用户的ip对应的地址")
private String address;
@TableField("browser")
@ApiModelProperty("执行操作的用户所使用的浏览器")
@ExcelProperty("执行操作的用户所使用的浏览器")
private String browser;
@TableField("os")
@ApiModelProperty("执行操作的用户所使用的操作系统")
@ExcelProperty("执行操作的用户所使用的操作系统")
private String os;
@TableField("oper_time")
@ApiModelProperty("操作时间")
@ExcelProperty(value = "操作时间",converter = LocalDateTimeConverter.class)
private LocalDateTime operTime;
@TableLogic//逻辑删除
@TableField("del_flag")
@ApiModelProperty("删除标志(0代表未删除,1代表已删除)")
@ExcelProperty(value = "删除标志",converter = DelFlagConverter.class)
private Integer delFlag;
}
- 4:创建一个中转类(也就是说我们报错的原因是OperationLog类中的LocalDateTime属性,这个时候我们可以创建一个新的类,其他字段不变,把这个LocalDateTime日期类变成String就可以解决这个bug)
-
原因:(这是由于canal+SpringBoot中的StringConvertUtil类的源码的问题):
- 可以看到下面的源码没有对LocalDateTime转LocalDatetime进行处理,而是把LocalDateTime转为String类型进行返回(问题出在
type.equals(java.sql.Date.class) ? parseDate(columnValue) : columnValue
),而columnValue是String类型,所以我们可以用String类型去接收LocalDateTime类型。

- 7:创建一个canal监听类(非常核心),指定监听一个表(这里我监听的是sys_oper_log表):
package com.boot.canal;
import cn.hutool.core.bean.BeanUtil;
import com.boot.entity.OperationLog;
import com.boot.entity.OperationLogCanal;
import com.boot.service.OperationLogService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import top.javatool.canal.client.annotation.CanalTable;
import top.javatool.canal.client.handler.EntryHandler;
/**
* 操作日志canal处理器
*
* @author youzhengjie
* @date 2022/10/30 15:19:09
*/
@CanalTable("sys_oper_log") //@CanalTable("sys_oper_log"):指定canal监听的表名为sys_oper_log
@Component
@Slf4j
public class OperationLogCanalHandle implements EntryHandler<OperationLogCanal> {
@Autowired
private OperationLogService operationLogService;
@Override
public void insert(OperationLogCanal operationLogCanal) {
//编写mysql和缓存同步的逻辑(例如JVM本地缓存、Redis分布式缓存、es等)
OperationLog operationLog = new OperationLog();
//bean拷贝
BeanUtil.copyProperties(operationLogCanal,operationLog);
//同步到es中
operationLogService.addOperationLogToEs(operationLog);
log.warn("OperationLogCanalHandle->insert->开始同步->"+operationLog);
}
/**
* 更新
*
* @param before 之前
* @param after 之后
*/
@Override
public void update(OperationLogCanal before, OperationLogCanal after) {
//编写mysql和缓存同步的逻辑(例如JVM本地缓存、Redis分布式缓存、es等)
OperationLog operationLog = new OperationLog();
//注意:要拷贝after对象,这个对象是修改之后的对象
BeanUtil.copyProperties(after,operationLog);
//同步es
operationLogService.updateOperationLogToEs(operationLog);
log.warn("OperationLogCanalHandle->update->开始同步->"+operationLog);
}
@Override
public void delete(OperationLogCanal operationLogCanal) {
//编写mysql和缓存同步的逻辑(例如JVM本地缓存、Redis分布式缓存、es等)
Long id = operationLogCanal.getId();
//同步es
operationLogService.deleteOperationLogToEs(id);
log.warn("OperationLogCanalHandle->delete->开始同步->"+id);
}
}
