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/resources/mybatis/mybatis-config.xml | 19 ++++++++++++------- 1 files changed, 12 insertions(+), 7 deletions(-) diff --git a/ruoyi-admin/src/main/resources/mybatis/mybatis-config.xml b/ruoyi-admin/src/main/resources/mybatis/mybatis-config.xml index c7c36e3..4b8c496 100644 --- a/ruoyi-admin/src/main/resources/mybatis/mybatis-config.xml +++ b/ruoyi-admin/src/main/resources/mybatis/mybatis-config.xml @@ -3,13 +3,18 @@ PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> - - <settings> - <setting name="cacheEnabled" value="true" /> <!-- 全局映射器启用缓存 --> - <setting name="useGeneratedKeys" value="true" /> <!-- 允许 JDBC 支持自动生成主键 --> - <setting name="defaultExecutorType" value="REUSE" /> <!-- 配置默认的执行器 --> - <setting name="logImpl" value="SLF4J" /> <!-- 指定 MyBatis 所用日志的具体实现 --> - <!-- <setting name="mapUnderscoreToCamelCase" value="true"/> 驼峰式命名 --> + <!-- 全局参数 --> + <settings> + <!-- 使全局的映射器启用或禁用缓存 --> + <setting name="cacheEnabled" value="true" /> + <!-- 允许JDBC 支持自动生成主键 --> + <setting name="useGeneratedKeys" value="true" /> + <!-- 配置默认的执行器.SIMPLE就是普通执行器;REUSE执行器会重用预处理语句(prepared statements);BATCH执行器将重用语句并执行批量更新 --> + <setting name="defaultExecutorType" value="SIMPLE" /> + <!-- 指定 MyBatis 所用日志的具体实现 --> + <setting name="logImpl" value="SLF4J" /> + <!-- 使用驼峰命名法转换字段 --> + <!-- <setting name="mapUnderscoreToCamelCase" value="true"/> --> </settings> </configuration> -- Gitblit v1.9.2
