java11 升级到java17 项目启动正常，执行mybatis 查询的时候报错
根据报错信息怀疑mybatis xml 配置问题，发现其实没有问题，jdk11 的时候正常启动

搜索资料发现
有人在升级到jdk9 的时候遇到同样问题
通过增加启动参数
--add-opens java.base/java.lang=ALL-UNNAMED
原文信息
会出现以下错误信息：
Exception in thread “main”
java.lang.reflect.InaccessibleObjectException: Unable to make field
private static final long java.lang.Long.serialVersionUID accessible:
module java.base does not “opens java.lang” to unnamed module
@224aed64

at java.base/java.lang.reflect.Field.setAccessible(Field.java:165)
at com.jdojo.intruder.TestManifestAttributes.main(TestManifestAttributes.java:10)
运行时错误表明应用程序无法访问私有静态serialVersionUID，因为java.base模块中的java.lang包未打开。我们先试试–add-opens这个选项：C:\Java9Revealed>java --add-opens java.base/java.lang=ALL-UNNAMED
-jar com.jdojo.intruder\dist\com.jdojo.intruder.jar 输出信息如下：Long.serialVersionUID=4290774380558885855 此命令工作正常，并验证命令行选项是这种情况下的解决方案。
我们使用MANIFEST.MF文件中的Add-Opens属性来修复此错误，如下所示。Manifest-Version: 1.0 Main-Class:
com.jdojo.intruder.TestManifestAttributes Add-Opens:
java.base/java.lang 使用相同的命令重新创建可执行文件JAR并运行它：C:\Java9Revealed>java -jar
com.jdojo.intruder\dist\com.jdojo.intruder.jar 输出结果为：Long.serialVersionUID=4290774380558885855
再次运行项目，查询数据成功
总结：java11升级到java17 是在家中个人电脑，非生产环境，
遇到问题到解决问题大概5小时，因为工程是shareding 研究项目，涉及众多知识点，定位问题时间较长。
疑难：项目本身jdk11 启动没问题，但是升级jdk15 之后报错。
