Example 4 with ELProcessor

use of javax.el.ELProcessor in project Payara by payara.

the class RealmUtil method getConfiguredValue.

static <T> T getConfiguredValue(Class<T> type, T value, Config provider, String mpConfigKey) {
    T result = value;

Example 5 with ELProcessor

use of javax.el.ELProcessor in project tomee by apache.

the class TomEEDatabaseIdentityStore method init.

@PostConstruct
private void init() throws Exception {
    definition = definitionSupplier.get();
    validationTypes = new HashSet<>(asList(definition.useFor()));
    passwordHash = getInstance(definition.hashAlgorithm());
    final ELProcessor elProcessor = new ELProcessor();
    elProcessor.getELManager().addELResolver(beanManager.getELResolver());
    // the trick with hashAlgorithmParameters is that it returns a String[]
    // each of them may be an EL to evaluate
    // and then we need to create a Map to pass in the password hash class
    // 1. get the list of String and evaluate expressions
    // 2. then split and create the map
    passwordHash.initialize(stream(definition.hashAlgorithmParameters()).flatMap(s -> toStream(eval(elProcessor, s, Object.class))).collect(toMap(s -> (String) s.substring(0, s.indexOf('=')), s -> (String) eval(elProcessor, s.substring(s.indexOf('=') + 1), String.class))));
