How to get field from context?

Question

Java

For a server application, authorization is required in some third-party services through a login, password, key, etc., in a word, ordinary String constant fields. In order to avoid having to rebuild and deploy the project when changing this data, as I understand it, you can write them as in context.xml which is located in webapp/META-INF and, if necessary, edit only this xml "hot".
1. How to get these fields from the context?
2. Is it safe to store such data in this way? If not, what is the best way?

Answer 1

@ConfigurationProperties, for example
and then sp-el and away we go

@Value("${name}")
private String name;
