If you’re looking to simplify Excel file handling in your Spring Boot applications, look no further! The Excel Spring Boot Starter is an easy way to leverage Java’s EasyExcel capabilities. Whether it’s uploading or downloading Excel files, this library makes the process seamless. Let’s dive into how to set it up and utilize it in your projects.

Setting Up Excel Spring Boot Starter

Before you can start working with Excel files, you’ll need to set up your pom.xml file with the relevant dependencies. This is akin to ensuring you have all the ingredients before baking a cake!

Creating Your Data Model

Next, you need to create a data model that represents the structure of your Excel file. Think of it as the blueprint of the cake you are about to make!

@Data
public class Demo {
    @ExcelProperty(index = 0)
    private String username;

    @ExcelProperty(index = 1)
    private String password;
}

Uploading Excel Files

After defining your model, you will want to implement a method for uploading Excel files. Here’s where the magic happens—converting the file into usable data in your application.

@PostMapping("/upload")
public void upload(@RequestExcel List dataList, BindingResult bindingResult) {
    List errorMessageList = (List) bindingResult.getTarget();
    // Handle your logic
}

Generating Excel Files

Now, let’s get into how to generate and download Excel files. You will define a method that utilizes the @ResponseExcel annotation to create your Excel file based on your data.

@Documented
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface ResponseExcel {
    String name() default "";
    ExcelTypeEnum suffix() default ExcelTypeEnum.XLSX;
    Sheet[] sheets() default @Sheet(sheetName = "sheet1");
    boolean inMemory() default false;
}

Troubleshooting Common Issues

• Missing Dependencies: Double-check your pom.xml for any missing entries. Often, failing to include a required library can cause compilation issues.
• Binding Errors: Ensure that your data model matches the structure of your Excel sheet. Any mismatch will lead to binding errors at runtime.
• File Format Issues: Make sure the file format you are trying to upload or download is compatible with the configurations set in the code.
