1. 检查AWS Lambda函数中是否正确引用了MicronautRequestHandler。

2. 确认是否正确使用了shadowJar插件并启用了minimize选项。在build.gradle中添加以下内容：

   shadowJar { minimize() }

3. 确认是否正确配置了Micronaut的依赖项。确保在build.gradle中添加以下依赖项：

   implementation("io.micronaut:micronaut-function-aws:2.0.0") implementation("io.micronaut.aws:micronaut-aws-sdk:3.0.0")

4. 如果仍然遇到错误，请尝试使用其他版本的Micronaut和AWS SDK。可以在文档中查找相应的版本兼容性。

参考代码示例：

1. build.gradle文件

plugins { id 'java' id 'application' id "com.github.johnrengelman.shadow" version "6.1.0" }

repositories { jcenter() }

dependencies { implementation platform('io.micronaut:micronaut-bom:2.0.0') implementation "io.micronaut:micronaut-http-client" implementation "io.micronaut:micronaut-http-server-netty" implementation "io.micronaut:micronaut-inject" implementation "io.micronaut.aws:micronaut-function-aws:2.0.0" implementation "io.micronaut.aws:micronaut-aws-sdk:3.0.0" }

application { mainClassName = "com.example.Application" }

shadowJar { minimize() }

2. Application.java文件

package com.example;

import io.micronaut.function.aws.MicronautRequestHandler;

public class Application extends MicronautRequestHandler {}

3. Handler.java文件

package com.example;

import com.amazonaws.services.lambda.runtime.Context; import io.micronaut.core.annotation.NonNull; import io.micronaut.function.executor.FunctionInitializer; import io.micronaut.function.executor.FunctionInitializerHandler; import java.util.Optional
