自定义基于注解形式的Excel解析器框架

Myth丶恋晨 2022-06-06 09:18 193阅读 0赞

基于poi 3.16版本

<dependency>
 <groupId>org.apache.poi</groupId>
 <artifactId>poi</artifactId>
 <version>3.10.1</version>
 </dependency>

使用方式基本不变，参照另外一篇博客[这基于自定义的Excel解析框架的使用范例][Excel]

下面介绍下框架中有哪些类，每个类的职责:

![Excell解析框架类目][Excell]

Excel : 对poi的封装，提供一些简单方便的获取poi数据的方法；

ExcelColumn : 自定义注解，标识Model的属性或者getter方法上，建议Excel Column到Filed的映射；

ExcelInstance : 存储了每行解析生成的对象实例及行序号；

ExcelMapping : 自定义注解，标识在Model Class上，指定数据起始行，标题行，及数据Sheet码；

ExcelMappingProcessor : Excel解析器，最重要的类，负责解析注解建立映射关系及解析Excel数据；

ExcelPromptAuthor : 批注的标识

PropertyInitializer : Model初始化器，Model实现此接口，在解析Excel每行数据前通过此接口获取Model实例。

ExcelException : 自定义的异常，在解析Excel时遇到非正常错误时抛出

ExcelMappingException : 自定义异常，在解析单元格遇到类型不匹配及行唯一性冲突时抛出，由自定义的异常处理器决定如何处理这个异常，同时是否继续解析；

**MappingExceptionResolver** : 映射异常处理器，负责处理解析过程中抛出的可处理异常，比如单元格数据类型与属性类型不匹配，行与行之间的唯一性字段重复。处理异常后可决定是否再继续解析Excel数据 。此接口时本次改进的关键，灵活的处理解析过程中的异常，可自由决定是否中途停止解析等，可以自定义自己的异常处理器，增加框架可扩展性。

ExcelEditorExceptionResolver : 实现了MappingExceptionResolver 接口，自定义了异常处理，将类型不匹配异常以批注的形式添加到相应的单元格上，对于行唯一性冲突异常，对冲突行的后者，在最后列+1上标识上冲突信息。

CombiningExceptionResolver : 实现了MappingExceptionResolver 接口，自定义了异常处理，将每行的类型不匹配信息合并起来，再加上行冲突信息，最前面加行号组合成文字信息，供前端展示。当错误行大于10时，中止解析过程。

测试方法代码:

@Test
 public void testParsingWithEditor() throws Exception {
 File original = new File("C:\\Users\\dell-7359\\Desktop\\Excel原始数据.xlsx");
 Excel excel = new Excel(original);
 processor = new ExcelMappingProcessor<ExcelModelExtends>(excel, ExcelModelExtends.class, new ExcelEditorExceptionResolver());
 boolean success = processor.process();
 Collection<ExcelInstance<ExcelModelExtends>> results = processor.getCorrectResult();
 System.out.println(results.size());
 File errorFile = new File("C:\\Users\\dell-7359\\Desktop\\Excel原始数据1.xlsx");
 errorFile.createNewFile();
 excel.write(errorFile);
 }
 
 @Test
 public void testParsingWithCombining() throws Exception {
 File original = new File("C:\\Users\\dell-7359\\Desktop\\Excel原始数据.xlsx");
 Excel excel = new Excel(original);
 CombiningExceptionResolver exceptionResolver = new CombiningExceptionResolver();
 processor = new ExcelMappingProcessor<ExcelModelExtends>(excel, ExcelModelExtends.class,exceptionResolver);
 boolean success = processor.process();
 if(!success){
 System.out.println(exceptionResolver.getCombinedMsg());
 }
 }

下面就将每个类的相应代码附上:
