Description

异常代码

EasyExcel.write(this.file).autoCloseStream(true) .registerWriteHandler(new CustomColumnWidthStyleStrategy()) .registerWriteHandler(horizontalCellStyleStrategy) .automaticMergeHead(true) .build();

异常提示

easyexcel:3.0.2

在项目中引入后,通过maven的包含全部依赖打包,生成的ExcelWriterBuilder的class未继承AbstractExcelWriterParameterBuilder类,并且在执行到registerWriteHandler时报一下错误 java.lang.NoSuchMethodError: com.alibaba.excel.write.builder.ExcelWriterBuilder.registerWriteHandler(Lcom/alibaba/excel/write/handler/WriteHandler;)Lcom/alibaba/excel/write/builder/AbstractExcelWriterParameterBuilder;

Research direction
Investigate the class hierarchy of ExcelWriterBuilder in the easyexcel library. The error indicates that at runtime, the class does not extend AbstractExcelWriterParameterBuilder, likely due to a shaded jar or version mismatch. Check the Maven shade plugin configuration or dependency resolution. Compare the compile time and runtime classpath to ensure consistent versions.
