Amazon Q 提供智能代码补全，支持单行、多行和整函数补全。它基于上下文和 AWS 最佳实践提供建议。尤其擅长 AWS SDK 调用，能推荐正确的 API 用法和参数。支持引用追踪，识别开源代码引用。

bash
# Code completion example
# Input:
import boto3
s3 = boto3.client('s3')
# Amazon Q will suggest:
# response = s3.list_buckets()
# for bucket in response['Buckets']:
#     print(bucket['Name'])
05

聊天

Amazon Q Chat 提供对话式 AI 助手。你可以提问代码问题、AWS 服务问题、架构建议等。聊天能理解项目上下文，可引用当前文件。支持 AWS 文档搜索，提供准确的 AWS 信息。

bash
# Use Chat
# Shortcut: Alt+Q

# Example conversations:
# "How to upload large files with S3?"
# "Explain what this Lambda function does"
# "How to optimize this DynamoDB query?"
# "Add CloudWatch monitoring for this API"
06

安全扫描

Amazon Q 提供安全扫描功能，自动检测代码中的安全问题。支持 OWASP Top 10、CWE 等安全标准。扫描结果包括漏洞描述、严重程度和修复建议。这是 Amazon Q 的独特优势，帮助开发者编写更安全的代码。

bash
# Run a security scan
# In the Amazon Q panel:
# 1. Click the "Scan" button
# 2. Select the scan scope (current file/project)
# 3. View scan results
# 4. Fix issues based on suggestions

# Or via command:
# Cmd+Shift+P -> "Amazon Q: Scan Code"
07

代码转换

Amazon Q 支持代码转换，如 Java 版本升级和框架迁移。它可以自动将 Java 8 代码升级到 Java 17，或从 Spring Boot 2 迁移到 3。转换过程包括代码修改、依赖更新、测试验证等。这显著降低了升级的工作量。

bash
# Code transformation example
# 1. Select "Transform" in the Amazon Q panel
# 2. Select the transformation type (e.g., Java 8 -> 17)
# 3. Select the project
# 4. Amazon Q analyzes and generates a transformation plan
# 5. Execute the transformation
# 6. Verify the results
08

AWS 集成

Amazon Q 与 AWS 服务深度集成。它可以协助 AWS 资源管理、CloudFormation 模板编写、IAM 策略生成等。支持 AWS CLI 命令生成和错误诊断。对于 AWS 用户，Amazon Q 是提升效率的强大工具。

bash
# AWS integration example
# Generate a CloudFormation template
# "Create an S3 bucket with versioning enabled"

# Amazon Q generates:
Resources:
  MyBucket:
    Type: AWS::S3::Bucket
    Properties:
      VersioningConfiguration:
        Status: Enabled

# Option B (enterprise): IAM Identity Center
aws configure sso
# Option C: access keys
aws configure

# VS Code settings
{
  "amazonq.enableSuggestions": true,
  "amazonq.enableChat": true,
  "amazonq.referenceTracker": "log"
}

# Security scanning: Amazon Q panel -> Scan -> select scope

A: Yes—free tier includes unlimited code completion, 50 chats/month, and
   security scanning. Pro ($19/month) raises limits and adds management.

Q: Do I need an AWS account?
A: You need AWS Builder ID (free) or an IAM Identity Center login; no
   full AWS account is required for the free tier.

Q: What does security scanning detect?
A: OWASP Top 10 and CWE issues, with severity and fix suggestions; run it
   from the Amazon Q panel.

Q: Can it transform legacy code?
A: Yes—Code Transformation upgrades Java 8 -> 17 and migrates Spring Boot
