问题遇到的现象和发生背景

Springboot自定义配置类，jackson序列化后带有额外信息

问题相关代码，请勿粘贴截图

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.3.7.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

自动配置类

@Data
@NoArgsConstructor
@AllArgsConstructor
@Configuration
@ConfigurationProperties(prefix = "risk-engine")
public class RiskEngineConfiguration{
    public Boolean delay_need;
    public Boolean work_need;
    public Boolean honest_need;
    public Boolean age_need;

    public Integer delay_year;
    public Integer delay_count;
    public Integer delay_return_days;
    public Integer delay_money_min;
    public Integer age_min;
}

application.yaml的有关内容

risk-engine:
  delay_need: true
  work_need: true
  honest_need: true
  age_need: true
  delay_year: 3
  delay_count: 2
  delay_return_days: 3
  delay_money_min: 1000
  age_min: 18

controller

@RestController
@RequestMapping("/riskengine")
public class RiskEngineController {

    @Autowired
    RiskEngineConfiguration riskEngineConfiguration;

    @GetMapping("/get")
    public RiskEngineConfiguration get(){
        System.out.println(riskEngineConfiguration);
        return riskEngineConfiguration;
    }
}

运行结果及报错内容

get请求：http://localhost:8080/riskengine/get
无限循环：{"parent":null,"name":"platform","registeredAsParallelCapable":true,"unnamedModule":{"name":null,"classLoader":
提示：浅浅的回车了一下，方便查看

{"delay_need":true,"work_need":true,"honest_need":true,"age_need":true,"delay_year":3,"delay_count":2,"delay_return_days":3,"delay_money_min":1000,"age_min":18,
"$$beanFactory":{"parentBeanFactory":null,"beanClassLoader":{"parent":
{"parent":null,"name":"platform","registeredAsParallelCapable":true,"unnamedModule":{"name":null,"classLoader":
{"parent":null,"name":"platform","registeredAsParallelCapable":true,"unnamedModule":{"name":null,"classLoader":
{"parent":null,"name":"platform","registeredAsParallelCapable":true,"unnamedModule":{"name":null,"classLoader":
{"parent":null,"name":"platform","registeredAsParallelCapable":true,"unnamedModule":{"name":null,"classLoader":

我的解答思路和尝试过的方法

1. 使用@Value一个个写参数应该是能解决（但这太麻烦了，以后碰到很多参数的类似问题还是要解决）
2. 与Lombok无关，使用 setter&getter 也是一样的结果
3. 猜测：这是SpringBoot自动配置的包装类产生的问题，

我想要达到的结果

我只想要toString类似的内容（只有$$beanFactory之前的那些）

Configuration会生成cglib代理对象，你用Component注入配置类就没问题了
