使用 IronPDF for Java

将IronPDF定义为Java依赖项

pom.xml依赖项

要将IronPDF定义为依赖项，请将以下内容添加到您的pom.xml：

<dependencies>

    <!-- Adds IronPDF Java. Use the latest version in the version tag. -->
    <dependency>
        <groupId>com.ironsoftware</groupId>
        <artifactId>ironpdf</artifactId>
        <version>20xx.xx.xxxx</version>
    </dependency>

    <!-- Adds the slf4j logger which IronPDF Java uses. -->
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-simple</artifactId>
        <version>2.0.3</version>
    </dependency>

下载jar文件

可选择手动下载IronPDF JAR文件以独立使用。

首次构建和运行

首次运行项目时，将自动下载IronPdfEngine 二进制文件。在您首次调用IronPDF功能时，将启动IronPdfEngine 进程，并在您的应用程序关闭或进入空闲阶段时停止。

作为 Maven 依赖项安装 IronPDF 引擎

通过将 IronPDFEngine 添加为 Maven 依赖项，二进制文件将在加载依赖项期间下载：

此方法将避免冗长的启动过程，因为 IronPDFEngine 二进制文件已下载。
此外，对于不允许从外部来源下载的部署设置，这将是有益的。

如果您正在开发跨平台应用程序，只需将以下一个或多个代码片段添加到您的 pom.xml 文件中：

开始编写 Java 代码

定义依赖项后，您可以通过在Java代码顶部添加import com.ironsoftware.ironpdf.*语句开始。这里是一个简单的HTML到PDF示例以供启动：

// Import statement for IronPDF Java
import com.ironsoftware.ironpdf.*;

// Apply your license key
License.setLicenseKey("YOUR-LICENSE-KEY");

// Set a log path
Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));

// Render the HTML as a PDF. Stored in myPdf as type PdfDocument
PdfDocument myPdf = PdfDocument.renderHtmlAsPdf("<h1> ~Hello World~ </h1> Made with IronPDF!");

// Save the PdfDocument to a file
myPdf.saveAs(Paths.get("html_saved.pdf"));

// Import statement for IronPDF Java
import com.ironsoftware.ironpdf.*;

// Apply your license key
License.setLicenseKey("YOUR-LICENSE-KEY");

// Set a log path
Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));

// Render the HTML as a PDF. Stored in myPdf as type PdfDocument
PdfDocument myPdf = PdfDocument.renderHtmlAsPdf("<h1> ~Hello World~ </h1> Made with IronPDF!");

// Save the PdfDocument to a file
myPdf.saveAs(Paths.get("html_saved.pdf"));

Java

这是另一个简单的演示 URL 到 PDF 的示例：

// Import statement for IronPDF Java
import com.ironsoftware.ironpdf.*;

// Apply your license key
License.setLicenseKey("YOUR-LICENSE-KEY");

// Set a log path
Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));

// Render the URL as a PDF. Stored in myPdf as type PdfDocument
PdfDocument myPdf = PdfDocument.renderUrlAsPdf("https://ironpdf.com/java");

// Save the PdfDocument to a file
myPdf.saveAs(Paths.get("url_saved.pdf"));

// Import statement for IronPDF Java
import com.ironsoftware.ironpdf.*;

// Apply your license key
License.setLicenseKey("YOUR-LICENSE-KEY");

// Set a log path
Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));

// Render the URL as a PDF. Stored in myPdf as type PdfDocument
PdfDocument myPdf = PdfDocument.renderUrlAsPdf("https://ironpdf.com/java");

// Save the PdfDocument to a file
myPdf.saveAs(Paths.get("url_saved.pdf"));

Java

完整的 Main.java 示例

package org.example;

// Import statement for IronPDF Java
import com.ironsoftware.ironpdf.*;
import java.io.IOException;
import java.nio.file.Paths;

public class Main {

    public static void main(String[] args) throws IOException {
        // Apply your license key
        License.setLicenseKey("YOUR-LICENSE-KEY");

        // Set a log path
        Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));

        // Render the HTML as a PDF. Stored in myPdf as type PdfDocument
        PdfDocument myPdf = PdfDocument.renderHtmlAsPdf("<h1> ~Hello World~ </h1> Made with IronPDF!");

        // Save the PdfDocument to a file
        myPdf.saveAs(Paths.get("html_saved.pdf"));

    }

}

package org.example;

// Import statement for IronPDF Java
import com.ironsoftware.ironpdf.*;
import java.io.IOException;
import java.nio.file.Paths;

public class Main {

    public static void main(String[] args) throws IOException {
        // Apply your license key
        License.setLicenseKey("YOUR-LICENSE-KEY");

        // Set a log path
        Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));

        // Render the HTML as a PDF. Stored in myPdf as type PdfDocument
        PdfDocument myPdf = PdfDocument.renderHtmlAsPdf("<h1> ~Hello World~ </h1> Made with IronPDF!");

        // Save the PdfDocument to a file
        myPdf.saveAs(Paths.get("html_saved.pdf"));

    }
