⚠️ Potential issue

不建议故意引发异常

这段代码存在以下问题：

  1. 故意引发算术异常是危险的做法
  2. 使用 System.out.println 进行日志记录不符合最佳实践
  3. /error 端点与 Spring Boot 的默认错误处理端点冲突

建议按照以下方式修改代码：

-    @GetMapping("/error")
-    public void sayError() {
-        System.out.println(1/0);
-    }
+    @GetMapping("/demo-error")
+    public ResponseEntity<String> demonstrateError() {
+        logger.error("演示错误情况");
+        return ResponseEntity
+            .status(HttpStatus.INTERNAL_SERVER_ERROR)
+            .body("模拟的错误响应");
+    }

同时在类级别添加日志记录器：

private static final Logger logger = LoggerFactory.getLogger(HelloController.class);

@lusyoe 抱歉，我无法直接创建commit。不过我可以为您提供完整的更新后的文件内容，您可以使用它来更新文件：

package com.example.k8s.controller;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {
    private static final Logger logger = LoggerFactory.getLogger(HelloController.class);

    @GetMapping("/")
    public String sayHello() {
        return "Hello, World";
    }

    @GetMapping("/demo-error")
    public ResponseEntity<String> demonstrateError() {
        logger.error("演示错误情况");
        return ResponseEntity
            .status(HttpStatus.INTERNAL_SERVER_ERROR)
            .body("模拟的错误响应");
    }
}

您可以直接复制这段代码并更新文件内容。这样的改动会：

  1. 添加必要的导入
  2. 添加日志记录器
  3. 改进错误演示端点的实现
