Apache Commons BeanUtils is a Java-based utility to provide component based architecture.
Modules The library is distributed in three jar files:
commons-beanutils.jar - contains everything commons-beanutils-core.jar - excludes Bean Collections classes commons-beanutils-bean-collections.jar - only Bean Collections classes.
Example Sample code may look like as follows: /** * Example displaying the new default behaviour such that * it is not possible to access class level properties utilizing the * BeanUtilsBean, which in turn utilizes the PropertyUtilsBean. */ public void testSuppressClassPropertyByDefault() throws Exception { final BeanUtilsBean bub = new BeanUtilsBean(); final AlphaBean bean = new AlphaBean(); try { bub.getProperty(bean, "class"); fail("Could access class property!"); } catch (final NoSuchMethodException ex) { // Ok
/** * Example showing how by which one would use to revert to the * behaviour prior to the 1.9.4 release where class level properties were accessible by * the BeanUtilsBean and the PropertyUtilsBean. */ public void testAllowAccessToClassProperty() throws Exception { final BeanUtilsBean bub = new BeanUtilsBean(); bub.getPropertyUtils().removeBeanIntrospector(SuppressPropertiesBeanIntrospector.SUPPRESS_CLASS); final AlphaBean bean = new AlphaBean(); String result = bub.getProperty(bean, "class"); assertEquals("Class property should have been accessed", "class org.apache.commons.beanutils2.AlphaBean", result); }
