Question

我正在尝试设置一个可以通过REST访问的Spring-Boot应用程序。首先，我希望它仅输入一个数字并将数字2添加到其中并返回结果。

现在，我构建了一个WAR文件并将其部署在我的tomcat上，以便可以尝试从Angular项目访问它。首先，我想用cURL对其进行测试，以确保其正常工作。

我做了什么？

构建WAR文件
将WAR文件移到我的xampp/tomcat/webapps/
从xampp启动我的tomcat（在端口8080、8005、8009上运行）
打开cmd并进入我的cURL目录
执行以下命令：curl.exe -H "number: 5" http://localhost:8009/number/

错误：

意外抛出：错误：堆大小'数字：5'格式错误。

我进行了以下设置：

---DemoApplication.java

---/controller
|  |---NumberController.java
---/dto

---/service
   |---EntryService.java

NumberController.java

@RequestMapping("/number")
@RestController
public class NumberController {
    @Autowired
    EntryService entryService;

    @RequestMapping(value="/number/{number}")
    public EntryDto receiveNumber(int number) {
        return entryService.createEntryDtoFromNumber(number);
    }
}

EntryDto.java

public class EntryDto {

    private int value;

    public EntryDto(int value) {
        this.value = value;
    }

    public void increaseValue(int increaseValue) {
        this.value = this.value + increaseValue;
    }

    public int getValue() {
        return this.value;
    }

    public void setValue(int value) {
        this.value = value;
    }
}

EntryService.java

@Service
public class EntryService {

    public EntryDto createEntryDtoFromNumber(int number) {
        entryDto = new EntryDto(number);
        entryDto.increaseValue(2);
        return this.entryDto;
    }

}
