JSON.toJSON 转换 @Configuration 修饰的对象会出现死循环

```java
@Data
@NoArgsConstructor
@Configuration
public class TestConfig {

    /**
     * 测试 name
     */
    private String info = "name";

}

   @Autowired
   private TestConfig testConfig;

   @Test
    public void testXMLSelect() throws IOException {
        log.info("testConfig = {}", JSON.toJSON(testConfig));
    }
```
