如何通过jackson进行字符串验证？

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>

</dependency>

public class MyString {
    private String value;

    // 省略构造方法和其他方法

    public String getValue() {
        return value;
    }

    public void setValue(String value) {
        this.value = value;
    }
}

public class MyStringDeserializer extends JsonDeserializer<MyString> {
    @Override
    public MyString deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException {
        String value = jsonParser.getValueAsString();
        
        // 在这里进行字符串验证的逻辑判断，例如判断字符串长度、格式等
        
        MyString myString = new MyString();
        myString.setValue(value);
        return myString;
    }
}

public class MyString {
    @JsonDeserialize(using = MyStringDeserializer.class)
    private String value;

    // 省略构造方法和其他方法

    public String getValue() {
        return value;
    }

    public void setValue(String value) {
        this.value = value;
    }
}

ObjectMapper objectMapper = new ObjectMapper();
SimpleModule module = new SimpleModule();
module.addDeserializer(MyString.class, new MyStringDeserializer());
objectMapper.registerModule(module);

String jsonString = "{\"value\": \"example\"}";
try {
    MyString myString = objectMapper.readValue(jsonString, MyString.class);
    // 字符串验证通过，可以进行后续操作
} catch (JsonProcessingException e) {
    // 字符串验证失败，处理异常情况
}
