Class BootstrapConfigurationLoader

java.lang.Object

com.svenruppert.jsentinel.bootstrap.BootstrapConfigurationLoader

public final class BootstrapConfigurationLoader
extends Object

Loads BootstrapConfiguration from system properties and environment variables.

Sources, in order of precedence

1. System property (highest)
2. Environment variable
3. Caller-provided default (lowest)

Keys

Configuration keys

System property	Environment variable
security.bootstrap.mode	SECURITY_BOOTSTRAP_MODE
security.bootstrap.token.file	SECURITY_BOOTSTRAP_TOKEN_FILE
security.bootstrap.token.ttl	SECURITY_BOOTSTRAP_TOKEN_TTL

The TTL value is parsed as an ISO-8601 duration (e.g. PT15M, PT24H). If absent, the configuration default applies.

Invalid mode values fail fast with IllegalArgumentException; the caller decides whether to log + fall back or to abort startup.

BootstrapConfigurationLoader

public BootstrapConfigurationLoader()

Default loader reading from System.getProperty(String) and System.getenv(String).

BootstrapConfigurationLoader

public BootstrapConfigurationLoader(Function<String,String> sysprop,
 Function<String,String> env)

Test seam: inject custom sources.

Parameters:

sysprop - function returning system-property values (typically System.getProperty(String))

env - function returning environment-variable values (typically System.getenv(String))

Method Details

load

public BootstrapConfiguration load(BootstrapMode defaultMode,
 Path defaultTokenFile,
 Duration defaultValidity)

Builds a BootstrapConfiguration from the configured sources.

Parameters:

defaultMode - mode used when neither sysprop nor env supply one

defaultTokenFile - token file used in PERSISTENT_FILE mode when neither sysprop nor env supply one

defaultValidity - validity used when no TTL is configured

Returns:

resolved configuration

Throws:

IllegalArgumentException - if a configured value is unparseable
