源码修改编译
克隆SeaYunnel-Web源码到本地 git clone https://github.com/apache/seatunnel-web.git
在idea中打开项目
升级Pom中的SeaTunnel版本到2.3.4并重新导入依赖 seatunnel-framework.version2.3.3/seatunnel-framework.version改为seatunnel-framework.version2.3.4/seatunnel-framework.version
因为大部分用户使用SeaTunnel Web都是基于SeaTunnel-2.3.3 版本做的适配,而最新发布的SeaTunnel2.3.4 部分API发生了改动导致直接升级的过程中会出现API不兼容的问题所以本篇文章重点来了我们需要对调用SeaTunnel API的SeaTunnel Web源码部分进行修改修改完之后我们就能完全适配2.3.4最新版本。
社区推出了2.3.X及Web系列专属的社群感兴趣的小伙伴可以加社区小助手进群。

代码格式化
mvn spotless:apply
编译打包
mvn clean package -DskipTests
至此seatunnel web 适配 seatunnel2.3.4版本完成对应的安装包会在 seatunnel-web-dist/target目录下生成
Linux部署测试
这里具体请参考之前社区其他老师发布的文章Apache SeaTunnel Web部署指南
重要的配置项
1、seatunnel-web数据库相关配置application.yml
用来web服务中的数据持久化2、SEATUNNEL_HOME环境变量
seatunnel-web调用seaunnel的插件获取的API,扫描connector相关的连接器3、ST_WEB_HOME环境变量
seatunnel-web会加载seatunnel-web/datasource下的插件包这里决定了seatunnel-web支持哪些数据源的任务定义4、重要的配置文件
connector-datasource-mapper.yaml
该配置文件配置了支持的数据源类型以及该数据源支持的数据同步方式等信息比如是否支持多表同步、是否支持cdc等
hazelcast-client.yaml
seatunnel-web服务通过seatunnel-api的方式与seatunnel集群进行交互该配置文件配置了集群节点等相关信息
