Question

我是春季靴子的新手。

我有一个样本。

java class：

package bootSample;

import org.springframework.boot.*;
import org.springframework.boot.autoconfigure.*;
import org.springframework.stereotype.*;
import org.springframework.web.bind.annotation.*;

@Controller
@EnableAutoConfiguration
public class SampleController {
    @RequestMapping("/")
    @ResponseBody
    String home() {
        return "Hello World!";
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(SampleController.class, args);
    }
}

当我运行它时，会引发以下异常

属性文件：

 server.compression.enabled: true
 server.compression.min-response-size: 1

Answer 1

我认为有两件事可能是问题

1.你正在使用它的旧版本的springboot版本，当前版本是1.3，并且不需要任何里程碑

2.您正在使用的服务器的属性可能存在一些问题，请尝试删除它或发布您的完整属性文件，以便我们提供帮助。
