springboot配置文件0开头的数字自动被转换成为其他值/与原值不匹配: 000000转为0

在springboot配置文件需要使用字符串类型的数值时候，有时候直接写一个0开头的数值，例如001。配置生效之后，打印配置参数时候发现不对，输出的是数值1。

而yml中配置的：000000，输出的是：0

public class ConstructYamlInt extends AbstractConstruct {
        public ConstructYamlInt() {
        }

        public Object construct(Node node) {
            String value = SafeConstructor.this.constructScalar((ScalarNode)node).toString().replaceAll("_", "");
            int sign = 1;
            char first = value.charAt(0);
            if (first == '-') {
                sign = -1;
                value = value.substring(1);
            } else if (first == '+') {
                value = value.substring(1);
            }

            int basex = true;
            if ("0".equals(value)) {
                return 0;
            } else {
                byte base;
                if (value.startsWith("0b")) {
                    value = value.substring(2);
                    base = 2;
                } else if (value.startsWith("0x")) {
                    value = value.substring(2);
                    base = 16;
                } else {
                    if (!value.startsWith("0")) {
                        if (value.indexOf(58) == -1) {
                            return SafeConstructor.this.createNumber(sign, value, 10);
                        }

                        String[] digits = value.split(":");
                        int bes = 1;
                        int val = 0;
                        int i = 0;

                        for(int j = digits.length; i < j; ++i) {
                            val = (int)((long)val + Long.parseLong(digits[j - i - 1]) * (long)bes);
                            bes *= 60;
                        }

                        return SafeConstructor.this.createNumber(sign, String.valueOf(val), 10);
                    }

                    value = value.substring(1);
                    base = 8;
                }

                return SafeConstructor.this.createNumber(sign, value, base);
            }
        }
    }

解决方法：

config: "001"
或者
config: "000000"
