重要:必需的设置
- Zip 部署不受支持,因为 IronPDF 在运行时需要执行二进制文件。
- 您必须将
PackageType
设置为Image
。 因为 IronPDF for Java 只支持 Docker 部署。 - 您必须使用
AmazonLinux2
docker 镜像。 - 您必须设置以下IronPdfEngineWorkingDirectory:
Setting.setIronPdfEngineWorkingDirectory(Paths.get("/tmp/"));
JAVA
必须,因为这是AWS允许执行环境的唯一路径。
- 增加
/tmp
大小,默认值为512 MB。 请将其设置为至少1024 MB。 - 将
ironpdf-engine-linux-x64
依赖项包含到您的项目中:
<dependency>
<groupId>com.ironsoftware</groupId>
<artifactId>ironpdf-engine-linux-x64</artifactId>
<version>2022.xx.x</version>
</dependency>
XML
- 将 Lambda 超时设置为 330 秒,因为启动缓慢。
- 将 Lambda 内存大小设置为至少 1024 MB。
使用 IntelliJ IDEA 的 AWS Toolkit 快速开始 (AWS SAM)
安装工具:
- IntelliJ IDEA -下载 IntelliJ IDEA
- AWS 工具包 -为 JetBrains 设置 AWS 工具包
- SAM CLI -为无服务器应用程序安装 Sam cli
Docker安装 Docker 社区版
您在本地测试中可能还需要以下内容:
Java8 - Java8下载 Java SE 开发工具包 8
MavenMaven 的安装指南
创建项目。 (文件"->"新建"->"项目..."。)
配置:
包裹类型:
图像
运行环境:
java8
或java11
- SAM 模板:"Maven
- 将以下依赖项添加到
pom.xml
:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>2.0.3</version>
</dependency>
<dependency>

XML
- 将
App.java
中的handleRequest
函数代码改为:
import com.ironsoftware.ironpdf.*;
public APIGatewayProxyResponseEvent handleRequest(final APIGatewayProxyRequestEvent input, final Context context) {
APIGatewayProxyResponseEvent response = new APIGatewayProxyResponseEvent();
Settings.setDebug(true); //optional
Settings.setIronPdfEngineWorkingDirectory(Paths.get("/tmp/")); //requried!
try {
context.getLogger().log("RENDER PDF");
PdfDocument pdf = PdfDocument.renderUrlAsPdf("https://www.google.com");
context.getLogger().log("RENDER PDF SUCCESS");
pdf.saveAs("/tmp/my-first-pdf.pdf");
//Done! Now you can do anything with the pdf such as upload this pdf to S3.
//return something..
Map<String, String> headers = new HashMap<>();
headers.put("Content-Type", "application/json");
headers.put("X-Custom-Header", "application/json");
APIGatewayProxyResponseEvent response = new APIGatewayProxyResponseEvent()
.withHeaders(headers);
return response
.withStatusCode(200)
.withBody("ENJOY IRON-PDF!");
} catch (Exception e) {
return response
.withBody("{" + e.getMessage() + "}")
.withStatusCode(500);
}
}
JAVA
- 在
template.yaml
中设置 Lambda 配置:
Globals:
Function:
Timeout: 400
MemorySize: 2048
EphemeralStorage:
Size: 1024
#don't touch the other config
YAML
- 将 Dockerfile 更新为以下内容:
- 注意:对于Java8,请使用
java8.al2
镜像,因为它使用的是AmazonLinux2
,而java8
使用的是旧的AmazonLinux
。
