@Autowired
Environment env;

@GetMapping("properties")
public Map<String, Object> allProperties() {
    Map<String, Object> map = new HashMap<>();
    map.put("activeProfiles", env.getActiveProfiles());
    map.put("defaultProfiles", env.getDefaultProfiles());

    MutablePropertySources sources = ((AbstractEnvironment) env).getPropertySources();
    for (PropertySource<?> source : sources) {
        if (source instanceof EnumerablePropertySource) {
            EnumerablePropertySource propertySource = (EnumerablePropertySource) source;
            for (String s : propertySource.getPropertyNames()) {
                map.put(s, propertySource.getProperty(s));
            }
