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

    <dependency>
<groupId>commons-beanutils</groupId>
<artifactId>commons-beanutils</artifactId>

<version>1.9.3</version>
</dependency>
