Springboot introduces a plug-in to convert word to pdf (3 minutes to realize function development)

I. Introduction

Spring Boot is a very popular Java development framework that helps developers quickly develop web applications, RESTful APIs, and other Java applications. Spring Boot also provides a very powerful Spring Initializr, which can configure the basic information of the project at one time, making development easier and more efficient.

Recently, the Spring Boot community released a very interesting feature that converts Word documents to PDF documents. How is this function achieved? Let's take a look below.

2. Development steps

1. First, we need to add a Maven dependency to our Spring Boot project. This dependency includes a Maven plugin called spring-docx that converts Word documents to PDF documents.

<dependency>  
    <groupId>org.springframework.boot</groupId>  
    <artifactId>spring-boot-starter-web</artifactId>  
    <scope>provided</scope>  
</dependency>  
<!-- 转换 Word 文档为 PDF 文档的 Maven 插件 -->  
<dependency>  
    <groupId>org.springframework.boot</groupId>  
    <artifactId>spring-boot-starter-web-starter-opendocx</artifactId>  
</dependency>

2. Next, we need to include this plugin in our Spring Boot application. This plugin can be introduced by setting the spring.starter.web.view property in the application.properties file.

spring.starter.web.view=org.springframework.boot.web.servlet.view.InternalResourceView

3. Next, we can write a simple Spring Boot application to demonstrate how to convert a Word document to a PDF document.

import org.springframework.boot.SpringApplication;  
import org.springframework.boot.autoconfigure.SpringBootApplication;  
import org.springframework.web.bind.annotation.GetMapping;  
import org.springframework.web.bind.annotation.RequestMapping;  
import org.springframework.web.bind.annotation.RestController;  
  
@SpringBootApplication  
public class WordToPdfConverterApplication {
    
      
  
    public static void main(String[] args) {
    
      
        SpringApplication.run(WordToPdfConverterApplication.class, args);  
    }  
  
    @GetMapping("/word-to-pdf")  
    public String wordToPdf() {
    
      
        return "Word to PDF converter";  
    }  
}

4. In this application, we define a WordToPdfConverter interface using the @RestController annotation and specify a URL named /word-to-pdf in the @GetMapping annotation. When the user visits this URL, it will call the WordToPdfConverter interface to perform the conversion. Finally, we set the spring.starter.web.view property in the application.properties file to display the converted PDF document correctly in the application.

Through the above steps, we can use Spring Boot to convert Word documents into PDF documents. This function is very convenient and can help developers quickly convert Word documents to PDF documents and display them in Spring Boot applications.
