春天加载的堆栈跟踪

IIUC弹簧加载使我能够在不重新部署的情况下更改java服务器代码并且它可以工作，但是我得到了一个非常长的堆栈跟踪。这是什么意思？

我的课程，我可以在不重新启动码头的情况下重新加载

package hello;

import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.bind.annotation.RequestMapping;

@RestController
public class HelloController {

    @RequestMapping("/")
    public String index() {
        return "Greetings from Spring Boot!";
    }

}

但为什么我会得到堆栈跟踪以及如何解决它？

1 个答案:

答案 0 :(得分：2)

参考上文以及我将来的参考资料，我建议将其作为答案。

将依赖关系从1.2.1.RELEASE更改为1.2.5.RELEASE确实有效。
