当我尝试使用spring和file.properties时，我会看到错误

Question

我尝试使用spring with file.properties，但我看到错误：

org.springframework.beans.factory.parsing.BeanDefinitionParsingException:
 Configuration problem: Configuration problem: Id is required for element 'properties' when used as a top-level tag
Offending resource: class path resource [di.xml]
Offending resource: class path resource [di.xml]

我该怎么办？我有： Java类

import lombok.AllArgsConstructor;
import lombok.NoArgsConstructor;
import lombok.Value;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
@AllArgsConstructor(onConstructor = @__(@Autowired))
@Value
@Component("person")
@NoArgsConstructor(force = true)
public class SimplePerson implements Person {
    String firstName;
    String lastName;
    @org.springframework.beans.factory.annotation.Value("20")
    int age;
    Contact contact;
}

spring .xml文件

file.properties

firstName=Roma
lastName=Izmailov
age=20

Answer 1

尝试将ID属性添加到util：properties：

<util:properties id="someId" location="classpath:person.properties"/>
