@EnableConfigurationProperties失效了 不能将配置类导入容器

以前,我定义属性值都是在application开头的配置文件的,有一天自定义了一个配置文件名为ldj.properties.结合注解 @PropertySource 指定加载读取它,然后@EnableConfigurationProperties测试发现,使用的都是默认值,没有读取配置的值.

package com.dj.springtest.config.properties;

import lombok.Data;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Component;

/**
 * User: ldj
 * Date: 2023/7/14
 * Time: 23:27
 * Description: No Description
 */
@Data
//@Component("test") //直接然容器扫描成为Bean 成功
@PropertySource(value = "classpath:ldj.properties")
@ConfigurationProperties(prefix = "spring.test.config")
public class TestConfigProperties {

    private String name = "ldj";

    private Integer age = 18;

    //@ConfigurationProperties和 @Value 可以兼容的
    @Value("${demo.test.gender:女}")
    private String gender;
}

package com.dj.springtest.config;

import com.dj.springtest.config.properties.TestConfigProperties;
import com.dj.springtest.service.TestService;
import com.dj.springtest.service.TestServiceImpl;
import lombok.Data;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;

/**
 * User: ldj
 * Date: 2023/7/14
 * Time: 23:28
 * Description: No Description
 */
@Data
@Configuration
@Import(value = {TestConfigProperties.class}) //直接当普通类导入成Bean 成功,默认也是先从bootstrap,application开头的文件获取,没有再从ldj.properties获取
//@EnableConfigurationProperties(value = {TestConfigProperties.class}) //失败!! 属性值必须配置在application或者bootstrap开头文件才可以
public class TestConfig {

    @Bean
    @ConditionalOnMissingBean(TestService.class)
    public TestServiceImpl testService(TestConfigProperties properties) {
        return new TestServiceImpl(properties.getName(), properties.getAge());
    }

}
