 # JAVA解析Excel工具easyexcel
-Java解析、生成Excel比较有名的框架有Apache poi、jxl。但他们都存在一个严重的问题就是非常的耗内存，poi有一套SAX模式的API可以一定程度的解决一些内存溢出的问题，但POI还是有一些缺陷，比如07版Excel解压缩以及解压后存储都是在内存中完成的，内存消耗依然很大。easyexcel重写了poi对07版Excel的解析，能够原本一个3M的excel用POI sax依然需要100M左右内存降低到KB级别，并且再大的excel不会出现内存溢出，03版依赖POI的sax模式。在上层做了模型转换的封装，让使用者更加简单方便

 ### 读Excel
-测试代码地址：[https://github.com/alibaba/easyexcel/blob/master/src/test/java/com/alibaba/easyexcel/test/ReadTest.java](/src/test/java/com/alibaba/easyexcel/test/ReadTest.java)
+DEMO代码地址：[https://github.com/alibaba/easyexcel/blob/master/src/test/java/com/alibaba/easyexcel/demo/read/ReadTest.java](/src/test/java/com/alibaba/easyexcel/test/demo/read/ReadTest.java)
 
-读07版小于1000行数据返回List<List<String>>
-```
-List<Object> data = EasyExcelFactory.read(inputStream, new Sheet(1, 0));
-```
-读07版小于1000行数据返回List<? extend BaseRowModel>
-```
-List<Object> data = EasyExcelFactory.read(inputStream, new Sheet(2, 1,JavaModel.class));
-```
-读07版大于1000行数据返回List<List<String>>
-```
-ExcelListener excelListener = new ExcelListener();
-EasyExcelFactory.readBySax(inputStream, new Sheet(1, 1), excelListener);
+```java
+    /**
+     * 最简单的读
+     * <p>1. 创建excel对应的实体对象 参照{@link DemoData}
+     * <p>2. 由于默认异步读取excel，所以需要创建excel一行一行的回调监听器，参照{@link DemoDataListener}
+     * <p>3. 直接读即可
+     */
+    @Test
+    public void simpleRead() {
+        String fileName = TestFileUtil.getPath() + "demo" + File.separator + "demo.xlsx";
+        // 这里 需要指定读用哪个class去读，然后读取第一个sheet 文件流会自动关闭
+        EasyExcel.read(fileName, DemoData.class, new DemoDataListener()).sheet().doRead();
+    }
 ```
 
-读07版大于1000行数据返回List<? extend BaseRowModel>
-```
-ExcelListener excelListener = new ExcelListener();
-EasyExcelFactory.readBySax(inputStream, new Sheet(2, 1,JavaModel.class), excelListener);
-```
-读03版方法同上
