fix: v1.1.5-snapshot rdb-adapter 由关键字引起的异常 (#3026 #2783) by XuDaojie · Pull Request #3020 · alibaba/canal

XuDaojie · 2020-09-08T08:20:53Z

问题描述

~~当库名或表名包含关键字或 - 时抛异常 #3019 问题已关闭，第一个commit原本是解决这个问题的，后面发现可以通过调整配置解决~~
postgres 驱动不兼容 postgres:12.4 升级驱动为42.2.16
canal 1.1.5-alpha2 同步不兼容postgresql #3026 因有个表用了explain字段，源表新增数据后adapter同步时报SQLSyntaxErrorException异常 #2783
此pull request最初是想解决当库名或表名包含关键字或 - 时抛异常 #3019，后经@yansheng105 提醒这种实现不能兼容postgres，查看文档后发现rdb-adapter原本设计的是支持多种rdb数据库，#2358中兼容了mysql关键字后导致rdb-adapter只能兼容MySQL

解决过程

关键字处理主要涉及表名、字段名，对于表名可以通过在配置yml文件时直接加上标识符解决，而字段名存在关键字并且mapAll=true的话则目前代码无法处理，目前代码主要是处理的字段名关键字标识符的问题
不同数据库处理保留字的标识符不同，第一种方案是通过判断数据库连接自动确定标识符，第二种是通过增加配置项，
目前选的第二种方案，主要考虑不同数据库标识符不同，出现了未知的数据库也可以自行配置

mysql: select `name`,`date` from user;
postgresql: select "name","date" from user;
mssql: select [name],[date] from user;

新增配置

# postgres
dbMapping:
  database: retl
  table: xdual
  targetTable: '"a-b"'       # 处理表名包含关键字或`-`，直接引号通过声明表名即可解决
  targetPk:
    id: id
  targetKeywordsIdentifier:  # 新增配置项 关键字、保留字标识符(对表名无效)
    prefix: '"'              # 默认值为 `
    suffix: '"'              # 默认值为 `
  mapAll: true

这种写法不兼容postgresql

还有一处忘记修改了哦。
com.alibaba.otter.canal.client.adapter.rdb.support.SyncUtil

    public static String getDbTableName(MappingConfig.DbMapping dbMapping) {
        Map<String, String> keywordsIdentifier = dbMapping.getKeywordsIdentifier();
        String result = "";
        if (StringUtils.isNotEmpty(dbMapping.getTargetDb())) {
            result += keywordsIdentifier.get(RDBConstants.KEYWORDS_IDENTIFIER_PREFIX)
                    + dbMapping.getTargetDb()
                    + keywordsIdentifier.get(RDBConstants.KEYWORDS_IDENTIFIER_SUFFIX)
                    + ".";
        }
        result += keywordsIdentifier.get(RDBConstants.KEYWORDS_IDENTIFIER_PREFIX)
                + dbMapping.getTargetTable()
                + keywordsIdentifier.get(RDBConstants.KEYWORDS_IDENTIFIER_SUFFIX);
        return result;
    }

                + keywordsIdentifier.get(RDBConstants.KEYWORDS_IDENTIFIER_SUFFIX);
        return result;
    }

这里不是忘了，就是特意没改，通过调整配置处理的，以postgres为例

targetTable: date -> targetTable: '"date"'
targetTable: db.date -> targetTable: '"db"."date"'
上面那段代码里其实还少了段判断第2种情况的代码，但是有一个情况无法处理就是表名里就带了 .号的

第二种情况我认为应该使用targetDb和targetTable两个配置项来配置，这样表名带点号的也可以进行处理了。

题外话：
最近我在使用adapter远程配置的时候遇到修改application.yml会导致无限重启的问题，不知道您有没有遇到过？

你说的那个是可以那样处理，我也是习惯两个分开配置，这本来是可选项，但是代码里这样处理的话就变成必选项了

目前没遇到

adapter的配置重载都有问题，application时改了就无限重启，rdb映射文件改了要重启才能生效，后面那个找到原因了，第一个还没找到

应该是canal.conf.consumerProperties 你没配置，感觉你配置文件可能是拷贝的1.1.4的，这个参数应该是1.1.5新增的。

liminglin1995 · 2021-05-12T03:18:59Z

谢谢，就像你所说的，然后我按最新的1.1.5的模板来配置就可以了👍

liminglin1995 · 2021-05-25T03:16:36Z

hello，我升级到最新的版本用了你的分支，运行一段时间没什么问题，就是在canal重启的时候会丢数据，这个版本不能够断点重连吗？

我这是没问题的，用zk存储的进度。

liminglin1995 · 2021-06-30T11:54:44Z

我引用的是canal.instance.global.spring.xml = classpath:spring/file-instance.xml这个配置，meta.dat在运行时记录消费位点信息，每次停止adapter，meta.dat的内容就变成了{"clientDatas":[],"destination":"example"}了，你知道为什么吗？
