升级JDK21过程中遇到的问题和解决方案

更新于2024-11-05 08:00:0115 分钟7 千字489194280500
摘要

1、背景

我之前用的是JDK19，本来没打算升级的，但最近发现系统可能存在内存泄漏的问题（实际没有发生内存泄漏，将在另一篇文章中说明），排查过程中发现之前本地用的java版本是x86的，而我用的电脑是macbook M1pro的芯片，安装分析工具会报错，需要卸载原本的java重装。

重装的时候索性直接升到JDK21了，最近听说JDK21带来了不少新的特性，性能大幅提高，正好体验一下。

但是升级过程中还是遇到了一些问题，本文记录一下问题原因和对应的解决方案，希望对需要升级的朋友有所帮助～

2、问题一：NoSuchFieldError: JCImport does not have member field JCTree qualid"

2.1、问题描述

升级之后先是编译的时候遇到了这个报错

Fatal error compiling: java.lang.NoSuchFieldError:
Class com.sun.tools.javac.tree.JCTree$JCImport does not have member field 'com.sun.tools.javac.tree.JCTree qualid'

2.2、解决方案

问题原因在lombok，与 JDK 21 兼容的最低 Lombok 版本是 1.18.30，最小的 Spring Boot 版本是 3.1.4。

可以尝试先升级lombok至1.18.30或以上版本，若仍不行，再尝试升级Spring Boot 至3.1.4或以上版本。

请注意，如果在经过上述尝试后，即使重新运行构建后仍然出现错误，可能是由于 IntelliJ 有一些缓存仍在获取以前的 lombok 版本。在这种情况下尝试以下方法之一：

  1. Maven > Reload，或者右键单击 pom.xml 文件并选择 Maven > Reimport
  2. 重新启动 IntelliJ
  3. 我的终极解决方案：找到maven本地仓库，删除之前的Lombok本地仓库，重新启动 IntelliJ，并reload maven

3、问题二：java.lang.IllegalArgumentException: Unsupported class file major version 65

3.1、问题描述

我这边在解决上面一个问题后，本地编译变没有问题了。

但是尝试运行时报错 java.lang.IllegalArgumentException: Unsupported class file major version 65

3.2、解决方案

可以看错误栈，是这个类导致的：org.springframework.asm.ClassReader

低版本的springframework，ClassReader对JDK版本有限制，可以尝试升级spring-core

<!-- https://mvnrepository.com/artifact/org.springframework/spring-core -->
<dependency>
	<groupId>org.springframework</groupId>
	<artifactId>spring-core</artifactId>
	<version>6.1.3</version>
</dependency>

4、问题三：Failed to bind properties under 'mybatis-plus.configuration.mapped-statements[0].configuration.environment' to org.apache.ibatis.mapping.Environment

4.1、问题描述

修复上述问题后，再次尝试运行，发现仍旧无法启动，报错信息如下：

***************************
APPLICATION FAILED TO START
***************************

Description:

Failed to bind properties under 'mybatis-plus.configuration.mapped-statements[0].configuration.environment' to org.apache.ibatis.mapping.Environment:

    Reason: java.lang.IllegalStateException: Failed to extract parameter names for public org.apache.ibatis.mapping.Environment(java.lang.String,org.apache.ibatis.transaction.TransactionFactory,javax.sql.DataSource)

Action:

Update your application's configuration

4.2、解决方案

这个问题和jdk关系不大，主要是因为我刚刚把springboot的版本升级了，升级后的spring boot和旧的mybatis版本不兼容

我这里再把mybatis-plus的版本也升级了就没问题了

我用的springboot版本：3.2.2，mybatis-plus版本：3.5.5，都升级成了最新版
