How to integrate Jackson with Dotenvx?

You can integrate Jackson with Dotenvx to protect some sensitive fields, such as SSN, email or phone number.

  ObjectMapper getDotenvxObjectMapper() {
    SimpleModule simpleModule = new SimpleModule();
    simpleModule.addSerializer(new DotenvxGlobalJsonSerializer(publicKey));
    return JsonMapper.builder().addModules(simpleModule).build();
}

@Test
public void testJsonSerialize() throws IOException {
    Map<String, String> info = new HashMap<>();
    info.put("email", "private:demo@example.com");
    info.put("nick", "Jackie");
    final String jsonText = objectMapper.writeValueAsString(info);
    System.out.println(jsonText);
}

If text value prefixed with private:, and the value will be encrypted.
