Bean connector

You can use the BeanConnector to access a java bean data.

     Person person = new Person("Jan", 30);
     BeanConnector connector = BeanConnector.connect(person);
     System.out.println(connector.getProperty("age"));
     System.out.println(connector.getProperty("name"));

Config properties

Read configuration from multi place. For example, if a properties file in the jar file and the content is

example.key1=key1
example.key2=key2

And a properties file in the classpath(WEB-INF/classes or the home of a bach e.g.),and the content is

example.key1=cat

so, if you call

ConfigProperty configProperty = ConfigProperty.getInstance();
configProperty.setFileEncoding("UTF-8");
configProperty.setLocations(getResource());
configProperty.loadProperties();
configProperty.getProperty("example.key1", "default"); // return cat
configProperty.getProperty("example.key2", "default"); // return key2
List<Properties> history = configProperty.getAllPropertiesLoadedHistoryIncludeOverwrite(); // return all histories of all properties file loaded.
