升级Jackson至2.18.2后遇NoSuchMethodError，求非降级解决方案

问题背景 #

将Jackson从2.16.1升级至2.18.2后，调用工具类的toJsonString方法时抛出方法不存在的错误。

解决方案（不降级依赖） #

这个错误的核心原因是Jackson核心组件版本不一致：jackson-core的运行版本低于2.18.2，而jackson-databind已经升级到2.18.2，新版本databind调用了core中新增的releaseToPool()方法，但旧版本core没有该方法。

具体解决步骤：

1. 排查依赖冲突
   在项目根目录执行Gradle命令，查看所有引入jackson-core的依赖及版本：

   ./gradlew dependencies --configuration compileClasspath | grep jackson-core
   

   重点关注第三方依赖（如AWS SDK、Spring组件）引入的旧版本jackson-core。

2. 强制统一所有Jackson组件版本
   在build.gradle中添加版本强制配置，确保所有Jackson相关依赖都使用2.18.2：

   configurations.all {
       resolutionStrategy.force "com.fasterxml.jackson.core:jackson-core:${jacksonDatabindVersion}"
       resolutionStrategy.force "com.fasterxml.jackson.core:jackson-annotations:${jacksonDatabindVersion}"
       // 若使用其他Jackson模块，同步强制版本
       resolutionStrategy.force "com.fasterxml.jackson.datatype:jackson-datatype-jsr310:${jacksonDatabindVersion}"
       resolutionStrategy.force "com.fasterxml.jackson.module:jackson-module-afterburner:${jacksonDatabindVersion}"
   }
   

   该配置会覆盖所有第三方依赖引入的旧版本Jackson组件，保证版本完全一致。

3. 验证依赖一致性
   再次执行依赖树命令，确认所有jackson-core的版本均为2.18.2：

   ./gradlew dependencies --configuration compileClasspath | grep jackson-core
   

4. 清理并重新构建
   清理旧构建缓存，重新编译打包：

   ./gradlew clean build
   

补充说明 #

• BufferRecycler.releaseToPool()是Jackson 2.18.x新增的方法，必须保证jackson-core与jackson-databind版本严格匹配。
• 第三方依赖经常会自带旧版本Jackson，通过Gradle的resolutionStrategy.force是解决这类版本冲突的高效方式。
