错误分析：由于在参数上未显示使用注解来指定参数名，而编译时没有保留方法参数名，导致无法确定参数名，所以才报错。

开发环境：eclipse，jdk17，springboot3.2.x

解决方案

方案1

在方法参数上添加注解
@PathVariable(name=“id”, required = true)
@RequestParam(name=“id”)

方案2

编译时保留方法参数名

• eclipse编译设置：

设置编译时保留参数名

• idea设置：File > Settings > Build, Execution, Deployment > Compiler > Java Compiler > Additional command line parameters: （输入框中填写 -parameters）

• pom文件设置

      org.apache.maven.plugins     maven-compiler-plugin     3.11.0                            -parameters                

配置好了之后重新编译所有代码即可解决。
