Java SnakeYaml转储自动转换数字（表示为字符串）

我正在使用yaml转储方法为我的对象创建一个配置文件。我有以下代码：

Map<String, String> map = new HashMap<>();
map.put("phonenumber","7285042388");
map.put("name","Cristina");
DumperOptions dumperOptions1 = new DumperOptions();
dumperOptions1.setDefaultFlowStyle(DumperOptions.FlowStyle.BLOCK);
Yaml yaml2 = new Yaml(dumperOptions);
System.out.println(yaml2.dump(map));`

我希望显示的电话号码不带单引号。我注意到使用对象类型为值的映射可以解决这个问题，但我需要值类型为字符串。如何解决这个问题？

您可以使用String类的replaceAll方法将all替换为replaceAll（“，”）等emply空格；

Map<String, Object> map = new HashMap<>();
map.put("phonenumber",  new BigInteger("7285042388"));
map.put("name","Cristina");
DumperOptions dumperOptions1 = new DumperOptions();
dumperOptions1.setDefaultFlowStyle(DumperOptions.FlowStyle.BLOCK);
Yaml yaml2 = new Yaml(dumperOptions1);
System.out.println(yaml2.dump(map));

Map<String, Object> map = new HashMap<>();
map.put("phonenumber",  new BigInteger("7285042388"));
map.put("name","Cristina");
DumperOptions dumperOptions1 = new DumperOptions();
dumperOptions1.setDefaultFlowStyle(DumperOptions.FlowStyle.BLOCK);
Yaml yaml2 = new Yaml(dumperOptions1);
System.out.println(yaml2.dump(map));

phonenumber: 7285042388
name: Cristina
