1，首先我們建立一個Java實體類Person,並建立屬性name,age,gender,程式碼如下：

public class Person {
	private String name;
	private int age;
	private String gender;
	
	public Person(String n,int a,String g) {
		name = n;
		age = a;
		gender = g;
	}
	
	public String getName() {
		return name;
	}
	
	public int getAge() {
		return age;
	}
	public String getGender() {
		return gender;
	}
}
 

Person person = new Person("zhangsan", 30, "男");

 
    /**  
     * 獲取屬性名陣列  
     * */  
    private static String[] getFiledName(Object o){  
        Field[] fields=o.getClass().getDeclaredFields();  
        String[] fieldNames=new String[fields.length];  
        for(int i=0;i<fields.length;i++){  
//            System.out.println(fields[i].getType());  
            fieldNames[i]=fields[i].getName();  
        }  
        return fieldNames;  
    }  
 

 /* 根據屬性名獲取屬性值  
     * */  
    private static Object getFieldValueByName(String fieldName, Object o) {  
        try {    
            String firstLetter = fieldName.substring(0, 1).toUpperCase();    
            String getter = "get" + firstLetter + fieldName.substring(1);    
            Method method = o.getClass().getMethod(getter, new Class[] {});    
            Object value = method.invoke(o, new Object[] {});    
            return value;    
        } catch (Exception e) {    
          
            return null;    
        }    
    }   
     
 

StringBuilder sbName = new StringBuilder();
		StringBuilder sbValue = new StringBuilder();
		String[] fieldNames = getFiledName(person);
		 
		  for(int j=0 ; j<fieldNames.length ; j++){     //遍歷所有屬性
	               String name = fieldNames[j];    //獲取屬性的名字
	               Object value = getFieldValueByName(name,person);
	               sbName.append(name);
	               sbValue.append(value);
	                if(j != fieldNames.length - 1) {
	                	sbName.append("/");
	                	sbValue.append("/");
	                }
	              
	              
	        }
	      
	        System.out.println("attribute name:"+sbName.toString()); 
	        System.out.println("attribute value:"+sbValue.toString());
