1、自定义配置

# 自定义配置
zbj:

    # 自定义集合
    gfs:
      - a
      - b

2、读取

1）User类

package com.sgu.pojo;

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
import java.util.List;

/**
 * 满堂花醉三千客，一剑寒霜十四州。
 *
 * @Author 中瑞
 * @Date 2025/3/28 14:25
 */

@Component
@ConfigurationProperties(prefix = "zbj.user")
@Data
public class User {
	private String username;
	
	private String password;
	
	private List<String> gfs;
}

2）UserController类

package com.sgu.controller;

import com.sgu.pojo.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * 满堂花醉三千客，一剑寒霜十四州。
 *
 * @Author 中瑞
 * @Date 2025/3/28 14:26
 */

@RestController
@RequestMapping("/user")
public class UserController {

	@Autowired
	private User user;

	@GetMapping("/show")
	public User show() {
		return user;
	}
}
