Top 10 Spring Boot Tricks Every Java Developer Should Know
Spring Boot simplifies application development, but there’s more power under the hood than most developers realize. In this article, we’ll explore 10 tricks, each with a clear problem, a solution, code snippets, and real-world use cases — so you can write cleaner, more maintainable Spring Boot applications.
✅ 1. Use @ConfigurationProperties
Instead of Scattered @Value
❌ Problem:
Using @Value
for every config property leads to cluttered, unstructured configuration code.
@Value("${email.host}")
private String host;
@Value("${email.port}")
private int port;
✅ Solution:
Use @ConfigurationProperties
to group properties into a single, type-safe bean.
@ConfigurationProperties(prefix = "email")
@Component
public class EmailConfig {
private String host;
private int port;
// getters and setters
}
