问题描述

简要描述您碰到的问题。

环境信息

请填写以下信息：

  • OS信息： win10
  • JDK信息：1.8.0.301
  • 版本信息：2.0.14

重现步骤

如何操作可以重现该问题：

@Data
@Configuration
@ConfigurationProperties(prefix = "config")
public class Config {
    public String[] deviceCodes;
    public String barkPushUrl;
    public String barkPushToken;
    public String location;
    public List<String> storeNameWhiteList;
}

填充数据：Config(deviceCodes=[M, Q], barkPushUrl=https://baidu.com, barkPushToken=token, location=广东 深圳 南山区, storeNameWhiteList=[深圳湾])

针对于此类和数据，使用 JSON.toJSONString(config) 时抛出异常。（奇怪，通过直接new的方式创建这个对象就可以正常toJsonString，但是通过读配置文件，以注入的形式使用这个对象就会抛异常。）

复现代码

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.ActiveProfiles;

import com.alibaba.fastjson2.JSON;

@SpringBootTest
@ActiveProfiles("test")
public class IssuesTest {
    @Autowired
    Config configs;

    @Test
    public void test() {
        Config config = new Config();
        assertEquals("{}", JSON.toJSONString(config));

        System.out.println(configs.toString());
        System.out.println(JSON.toJSONString(configs));
    }
}

期待的正确结果

对您期望发生的结果进行清晰简洁的描述。

正常转为json string

附加信息

奇怪，通过直接new的方式创建这个对象就可以正常toJsonString，但是通过读配置文件的形式，就导致这里抛异常。

Configuration ConfigurationProperties 这两个是什么package下的？需要依赖什么类库？

@wenshao ，我在这里补充复现代码和环境依赖供您使用。

测试类代码

import static org.junit.jupiter.api.Assertions.assertEquals;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.ActiveProfiles;

import com.alibaba.fastjson2.JSON;


@SpringBootTest
@ActiveProfiles("test")
public class IssuesTest {
    @Autowired
    Config configs;

    @Test
    public void test() {
        //new对象时，可以正常toJSONString
        Config config = new Config();
        config.setLocation("广东");
        assertEquals("{\"location\":\"广东\"}", JSON.toJSONString(config));

        // 使用@Autowired 注入时，可以正常调用类toString打印属性，但是不能toJSONString
        System.out.println(configs.toString());
        System.out.println(JSON.toJSONString(configs));
    }
}

springboot application.yml 关于此对象的配置文件片段

config:
  deviceCodes:
    - 'M'
    - 'Q'
  barkPushUrl: https://baidu.com
  barkPushToken: token
  location: 广东 深圳 南山区
  storeNameWhiteList:
    - '深圳湾'

使用的springboot 依赖版本

       <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <version>2.7.4</version>
        </dependency>

        <!--         https://mvnrepository.com/artifact/com.alibaba/fastjson -->
        <dependency>

            <artifactId>fastjson</artifactId>
            <version>2.0.14</version>
        </dependency>

是因为bean被spring代理导致的？
