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(); 
                } 
        }

 pom.xml需要配依赖

<groupId>commons-beanutils</groupId>
