Java中通過例項得到實體類中的屬性和屬性值

方式一(實體類)：
| 1234567 | //java中遍歷實體類，獲取屬性名和屬性值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（實體類或拓展類）:
| 1234567891011121314 | 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();}} |
pom.xml需要配依賴
