From af0e0a110e7187bf008655f7510199a0c0b25ec4 Mon Sep 17 00:00:00 2001 From: Nymph2333 <498092988@qq.com> Date: 星期一, 10 四月 2023 14:27:40 +0800 Subject: [PATCH] newInstance() 已弃用,使用clazz.getDeclaredConstructor().newInstance() This method propagates any exception thrown by the nullary constructor, including a checked exception. Use of this method effectively bypasses the compile-time exception checking that would otherwise be performed by the compiler. The Constructor.newInstance method avoids this problem by wrapping any exception thrown by the constructor in a (checked) InvocationTargetException. The call clazz.newInstance() can be replaced by clazz.getDeclaredConstructor().newInstance() The latter sequence of calls is inferred to be able to throw the additional exception types InvocationTargetException and NoSuchMethodException. Both of these exception types are subclasses of ReflectiveOperationException. --- ruoyi-common/src/main/java/com/ruoyi/common/utils/poi/ExcelUtil.java | 19 +++++++++++++++---- 1 files changed, 15 insertions(+), 4 deletions(-) diff --git a/ruoyi-common/src/main/java/com/ruoyi/common/utils/poi/ExcelUtil.java b/ruoyi-common/src/main/java/com/ruoyi/common/utils/poi/ExcelUtil.java index dcc4d1e..cbe47b6 100644 --- a/ruoyi-common/src/main/java/com/ruoyi/common/utils/poi/ExcelUtil.java +++ b/ruoyi-common/src/main/java/com/ruoyi/common/utils/poi/ExcelUtil.java @@ -99,6 +99,11 @@ public static final String[] FORMULA_STR = { "=", "-", "+", "@" }; /** + * 用于dictType属性数据存储,避免重复查缓存 + */ + public Map<String, String> sysDictMap = new HashMap<String, String>(); + + /** * Excel sheet最大行数,默认65536 */ public static final int sheetSize = 65536; @@ -1034,7 +1039,12 @@ } else if (StringUtils.isNotEmpty(dictType) && StringUtils.isNotNull(value)) { - cell.setCellValue(convertDictByExp(Convert.toStr(value), dictType, separator)); + if (!sysDictMap.containsKey(dictType + value)) + { + String lable = convertDictByExp(Convert.toStr(value), dictType, separator); + sysDictMap.put(dictType + value, lable); + } + cell.setCellValue(sysDictMap.get(dictType + value)); } else if (value instanceof BigDecimal && -1 != attr.scale()) { @@ -1321,7 +1331,7 @@ */ public String encodingFilename(String filename) { - filename = UUID.randomUUID().toString() + "_" + filename + ".xlsx"; + filename = UUID.randomUUID() + "_" + filename + ".xlsx"; return filename; } @@ -1440,7 +1450,8 @@ Excel[] excels = attrs.value(); for (Excel attr : excels) { - if (attr != null && (attr.type() == Type.ALL || attr.type() == type)) + if (!ArrayUtils.contains(this.excludeFields, field.getName() + "." + attr.targetAttr()) + && (attr != null && (attr.type() == Type.ALL || attr.type() == type))) { field.setAccessible(true); fields.add(new Object[] { field, attr }); @@ -1598,7 +1609,7 @@ HSSFPicture pic = (HSSFPicture) shape; int pictureIndex = pic.getPictureIndex() - 1; HSSFPictureData picData = pictures.get(pictureIndex); - String picIndex = String.valueOf(anchor.getRow1()) + "_" + String.valueOf(anchor.getCol1()); + String picIndex = anchor.getRow1() + "_" + anchor.getCol1(); sheetIndexPicMap.put(picIndex, picData); } } -- Gitblit v1.9.2
