Spring Boot Windows Server: Fix StackOverflowError when using Aspose.PDF Accept Method
In this article, we will discuss how to fix the StackOverflowError that can occur when using the Aspose.PDF API to find text in a PDF document in a Spring Boot application deployed on a Windows Server.
Introduction
Aspose.PDF is a popular PDF manipulation library that allows developers to create, edit, and convert PDF documents programmatically. When building a Spring Boot application that performs document operations, such as finding text in a PDF document, it is common to use the Aspose.PDF API to accomplish this task.
However, when deploying the application on a Windows Server, you may encounter a StackOverflowError when using the Aspose.PDF API's Accept method to find text in a PDF document. This error occurs due to a limitation in the .NET framework's garbage collection mechanism on Windows Server.
Cause of the Error
The StackOverflowError occurs due to a limitation in the .NET framework's garbage collection mechanism on Windows Server. When the Aspose.PDF API's Accept method is used to find text in a PDF document, it creates a large number of temporary objects that consume a significant amount of memory.
On Windows Server, the .NET framework's garbage collector is less aggressive in cleaning up these temporary objects, leading to a buildup of memory usage and eventually causing a StackOverflowError.
Solution
To fix the StackOverflowError when using the Aspose.PDF API's Accept method to find text in a PDF document in a Spring Boot application deployed on a Windows Server, you can use the following solution:
- Use the Aspose.PDF API's TextAbsorber class instead of the Accept method to find text in a PDF document.
- Configure the .NET framework's garbage collector to be more aggressive in cleaning up temporary objects by setting the gcServer parameter to true in the application's configuration file.
Example
Here is an example of how to use the TextAbsorber class instead of the Accept method to find text in a PDF document in a Spring Boot application deployed on a Windows Server:
// Create a new TextAbsorber instance
TextAbsorber absorber = new TextAbsorber("text to find");
// Get the page count of the PDF document
int pageCount = pdfDocument.getPages().getCount();
// Loop through each page of the PDF document
for (int i = 1; i <= pageCount; i++) {
// Get the current page
Page page = pdfDocument.getPages().get_Item(i);
// Accept the TextAbsorber on the current page
page.accept(absorber);
}
// Get the text that was found
List textSegments = absorber.getTextSegments();
Significance
Fixing the StackOverflowError when using the Aspose.PDF API's Accept method to find text in a PDF document in a Spring Boot application deployed on a Windows Server is important to ensure that the application runs smoothly and without interruption.
In this article, we discussed how to fix the StackOverflowError that can occur when using the Aspose.PDF API to find text in a PDF document in a Spring Boot application deployed on a Windows Server. By using the TextAbsorber class instead of the Accept method and configuring the .NET framework's garbage collector to be more aggressive, you can prevent this error and ensure that your application runs smoothly and without interruption.
