  如何自定义Excel导入功能

  介绍 在平台提供的默认导入功能无法满足业务需求的时候，我们可以自定义导入功能，以满足业务中个性化的需求。 功能示例 下面以导入文件的时候加入发布人的字段作为示例讲解。 继承平台的导入任务模型，加上需要在导入的弹窗视图需要展示的字段 package pro.shushi.pamirs.demo.api.model; import pro.shushi.pamirs.file.api.model.ExcelImportTask; import pro.shushi.pamirs.meta.annotation.Field; import pro.shushi.pamirs.meta.annotation.Model; @Model.model(DemoItemImportTask.MODEL_MODEL) @Model(displayName = "商品-Excel导入任务") public class DemoItemImportTask extends ExcelImportTask { public static final String MODEL_MODEL = "demo.DemoItemImportTask"; // 自定义显示的字段 @Field.String @Field(displayName = "发布人") private String publishUserName; } 编写自定义导入弹窗视图的数据初始化方法和导入提交的action package pro.shushi.pamirs.demo.core.action; import org.springframework.stereotype.Component; import pro.shushi.pamirs.boot.base.resource.PamirsFile; import pro.shushi.pamirs.demo.api.model.DemoItemImportTask; import pro.shushi.pamirs.file.api.action.ExcelImportTaskAction; import pro.shushi.pamirs.file.api.config.FileProperties; import pro.shushi.pamirs.file.api.model.ExcelWorkbookDefinition; import pro.shushi.pamirs.file.api.service.ExcelFileService; import pro.shushi.pamirs.meta.annotation.Action; import pro.shushi.pamirs.meta.annotation.Function; import pro.shushi.pamirs.meta.annotation.Model; import pro.shushi.pamirs.meta.annotation.fun.extern.Slf4j; import pro.shushi.pamirs.meta.enmu.ActionContextTypeEnum; import pro.shushi.pamirs.meta.enmu.FunctionOpenEnum; import pro.shushi.pamirs.meta.enmu.FunctionTypeEnum; import pro.shushi.pamirs.meta.enmu.ViewTypeEnum; @Slf4j @Component @Model.model(DemoItemImportTask.MODEL_MODEL) public class DemoItemExcelImportTaskAction extends ExcelImportTaskAction { public DemoItemExcelImportTaskAction(FileProperties fileProperties, ExcelFileService excelFileService) { super(fileProperties, excelFileService); } @Action(displayName = "导入", contextType = ActionContextTypeEnum.CONTEXT_FREE, bindingType = {ViewTypeEnum.TABLE}) public DemoItemImportTask createImportTask(DemoItemImportTask data) { if (data.getWorkbookDefinitionId() != null) { ExcelWorkbookDefinition workbookDefinition = new ExcelWorkbookDefinition(); workbookDefinition.setId(data.getWorkbookDefinitionId()); data.setWorkbookDefinition(workbookDefinition); } Object fileId = data.get_d().get("fileId"); if (fileId != null) { PamirsFile pamirsFile = new PamirsFile().queryById(Long.valueOf(fileId.toString())); data.setFile(pamirsFile); } super.createImportTask(data); return data; } /** * @param data * @return */ @Function(openLevel = FunctionOpenEnum.API) @Function.Advanced(type = FunctionTypeEnum.QUERY) public DemoItemImportTask construct(DemoItemImportTask data) { data.construct(); return data; } } 编写导入的单行数据处理逻辑，此处可以拿到导入弹窗内自定义的字段提交的值，然后根据这些值处理自定义逻辑，此处演示代码就是将导入后的商品的发布人都设置为自定义导入视图填的发布人信息 package pro.shushi.pamirs.demo.core.excel.extPoint; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import pro.shushi.pamirs.demo.api.model.DemoItem; import pro.shushi.pamirs.demo.api.model.DemoItemImportTask; import pro.shushi.pamirs.demo.api.service.DemoItemService; import pro.shushi.pamirs.file.api.context.ExcelImportContext; import pro.shushi.pamirs.file.api.extpoint.AbstractExcelImportDataExtPointImpl; import pro.shushi.pamirs.file.api.extpoint.ExcelImportDataExtPoint;…

  平台配置日志输出和推送到APM与LogStash

  场景描述 目前设计器镜像启动后日志文件为out.log，是启动脚本中定向输出了(>>)out.log文件。实际项目可能： 日志输出到特定目录的特定文件名中 指定以日志保留策略(单个文件大小和文件保留个数) 日志输出到APM工具中(如skywalking) 日志推送到LogStash 日志自定义输出 不定向输出，采用自己配置的方式，与标准的SpringBoot工程配置日志一样。两种方式（都是Spring提供的方式）： 方式一 bootstrap.yml 里面可以按profiles指定logback的配置文件，具体文件名和文件输入在logback里面进行配置，跟通用的logback配置一致. 例如： logging: config: classpath:logback-pre.xml 方式二 resources的根目录，直接配置 logback-spring.xml， 启动会自动加载。 日志自定义场景 配置日志推送到LogStash <!–配置日志推送到LogStash–> <contextListener class="pro.shushi.pamirs.demo.core.config.DemoLogbackFiledConfig"/> <appender name="LogStash" class="net.logstash.logback.appender.LogstashTcpSocketAppender"> <destination>127.0.0.1:4560</destination> <!– encoder必须配置,有多种可选 –> <encoder charset="UTF-8" class="net.logstash.logback.encoder.LogstashEncoder"> <!– SkyWalking插件, log加tid–> <provider class="org.apache.skywalking.apm.toolkit.log.logback.v1.x.logstash.TraceIdJsonProvider" /> <!–在生成的json中会加这些字段–> <customFields> {"app.name":"pamirs-demo", "app.type":"Microservice", "platform":"pamirs", "env":"dev"} </customFields> <timeZone>Asia/Shanghai</timeZone> <writeVersionAsInteger>true</writeVersionAsInteger> <providers> <pattern> <pattern> <!–动态的变量–> { "ip": "%{ip}", "server.name": "%{server.name}", "logger_name": "%logger" } </pattern> </pattern> </providers> </encoder> </appender> skywalking的日志rpc上传 <!– skywalking的日志rpc上传 –> <appender name="SkyWalkingLogs" class="org.apache.skywalking.apm.toolkit.log.logback.v1.x.log.GRPCLogClientAppender"> <encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder"> <layout class="org.apache.skywalking.apm.toolkit.log.logback.v1.x.mdc.TraceIdMDCPatternLogbackLayout"> <Pattern>${CONSOLE_LOG_PATTERN}</Pattern> </layout> </encoder> </appender> 完整的代码示例 Logback自定义字段 package pro.shushi.pamirs.demo.core.config; import ch.qos.logback.classic.Level; import ch.qos.logback.classic.Logger; import ch.qos.logback.classic.LoggerContext; import ch.qos.logback.classic.spi.LoggerContextListener; import ch.qos.logback.core.Context; import ch.qos.logback.core.spi.ContextAwareBase; import ch.qos.logback.core.spi.LifeCycle; import java.net.InetAddress; import java.net.UnknownHostException; /** * Logback自定义字段 * * @author wx@shushi.pro * @date 2024/4/17 */ public class DemoLogbackFiledConfig extends ContextAwareBase implements LoggerContextListener, LifeCycle { private boolean started = false; @Override public boolean isResetResistant() { return false; } @Override public void onStart(LoggerContext loggerContext) { } @Override public void onReset(LoggerContext loggerContext) { } @Override public void onStop(LoggerContext loggerContext) { } @Override public void onLevelChange(Logger logger, Level level) { } @Override public void start() { if (started) { return; } Context context = getContext();…
