Spring Boot对接Web Push碰壁记录

import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.server.ResponseStatusException;
 
@RestController
public class PushController {
 
    // 假设这是与Push服务的交互逻辑
    private final PushService pushService;
 
    public PushController(PushService pushService) {
        this.pushService = pushService;
    }
 
    @GetMapping("/sendPush")
    public void sendPush() {
        if (!pushService.isPushSupported()) {
            throw new ResponseStatusException(HttpStatus.NOT_IMPLEMENTED, "Push不支持");
        }
        try {
            pushService.sendPushMessage();
        } catch (PushMessagingException e) {
            throw new ResponseStatusException(HttpStatus.INTERNAL_SERVER_ERROR, "发送Push失败", e);
        }
    }
}
 
// 假设PushService是这样的接口
interface PushService {
    boolean isPushSupported();
    void sendPushMessage() throws PushMessagingException;
}
 
// 假设PushMessagingException是这样的异常类
class PushMessagingException extends RuntimeException {
    public PushMessagingException(String message) {
        super(message);
    }
    // 可以添加更多的异常处理逻辑
}

这个示例展示了如何在Spring Boot应用中使用ResponseStatusException来处理Web Push服务的相关逻辑。当Push服务不可用时，会抛出一个HttpStatus.NOT_IMPLEMENTED状态的异常。如果在尝试发送Push消息时出现异常，则抛出HttpStatus.INTERNAL_SERVER_ERROR状态的异常，并附带异常信息和原因。
