java中遍历实体类 获取属性名和属性值

方式一(实体类)：

//java中遍历实体类，获取属性名和属性值public static void testReflect(Object model) throws Exception{for (Field field : model.getClass().getDeclaredFields()) {field.setAccessible(true);System.out.println(field.getName() + ":" + field.get(model) );}}

方式二（实体类或拓展类）:

public static void test2(Object obj) {try {PropertyUtilsBean propertyUtilsBean = new PropertyUtilsBean();PropertyDescriptor[] descriptors = propertyUtilsBean.getPropertyDescriptors(obj);for (int i = 0; i < descriptors.length; i++) {String name = descriptors[i].getName();if (!"class".equals(name)) {System.out.println(name+":"+ propertyUtilsBean.getNestedProperty(obj, name));}}} catch (Exception e) {e.printStackTrace();}}
