Build, compile, and run Spring Boot applications in your browser. Complete with Maven & Gradle support, live log streaming, REST controller debugging, Actuator inspection, and autonomous AI pair programming.
No local JDK setup, Maven home path issues, or heavy IDE memory footprints. Open and build instantly.
Full compatibility with modern Spring Boot 3 standards on OpenJDK 17 and OpenJDK 21 LTS, including Jakarta EE 10, Hibernate 6, and Spring WebFlux.
Run ./mvnw spring-boot:run or ./gradlew bootRun with real-time NDJSON console streaming. Build production-ready JARs with ./mvnw clean package.
Set breakpoints directly inside your Spring REST controllers, service layers, and repository implementations. Step through requests and inspect bean states.
Run integration tests with @SpringBootTest and MockMvc. View test reports, assertion diffs, and execution timings in the Tests panel.
Ask the AI agent to write clean REST controllers, configure Spring Security JWT filters, create JPA repositories, and generate MockMvc integration tests.
Test your REST endpoints with curl or inspect Spring Boot Actuator health endpoints directly from the integrated terminal in your cloud workspace.
Declarative Spring REST controllers with validation and dependency injection.
package com.example.api;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.*;
import java.util.Map;
@RestController
@RequestMapping("/api/orders")
public class OrderController {
@GetMapping("/{id}")
public ResponseEntity<Map<String, Object>> getOrder(@PathVariable Long id) {
return ResponseEntity.ok(Map.of(
"orderId", id,
"status", "CONFIRMED",
"runtime", "OnlineAIIDE Spring Boot Sandbox"
));
}
@PostMapping
public ResponseEntity<Map<String, Object>> createOrder(@RequestBody Map<String, Object> payload) {
return ResponseEntity.ok(Map.of(
"message", "Order processed successfully",
"details", payload
));
}
