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-admin/src/main/java/com/ruoyi/web/controller/system/SysDictTypeController.java | 5 ++--- 1 files changed, 2 insertions(+), 3 deletions(-) diff --git a/ruoyi-admin/src/main/java/com/ruoyi/web/controller/system/SysDictTypeController.java b/ruoyi-admin/src/main/java/com/ruoyi/web/controller/system/SysDictTypeController.java index bfd467e..9808842 100644 --- a/ruoyi-admin/src/main/java/com/ruoyi/web/controller/system/SysDictTypeController.java +++ b/ruoyi-admin/src/main/java/com/ruoyi/web/controller/system/SysDictTypeController.java @@ -14,7 +14,6 @@ import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import com.ruoyi.common.annotation.Log; -import com.ruoyi.common.constant.UserConstants; import com.ruoyi.common.core.controller.BaseController; import com.ruoyi.common.core.domain.AjaxResult; import com.ruoyi.common.core.domain.entity.SysDictType; @@ -72,7 +71,7 @@ @PostMapping public AjaxResult add(@Validated @RequestBody SysDictType dict) { - if (UserConstants.NOT_UNIQUE.equals(dictTypeService.checkDictTypeUnique(dict))) + if (!dictTypeService.checkDictTypeUnique(dict)) { return error("新增字典'" + dict.getDictName() + "'失败,字典类型已存在"); } @@ -88,7 +87,7 @@ @PutMapping public AjaxResult edit(@Validated @RequestBody SysDictType dict) { - if (UserConstants.NOT_UNIQUE.equals(dictTypeService.checkDictTypeUnique(dict))) + if (!dictTypeService.checkDictTypeUnique(dict)) { return error("修改字典'" + dict.getDictName() + "'失败,字典类型已存在"); } -- Gitblit v1.9.2
