遍历java对象中的属性

public static void Reflect(Object obj) throws NoSuchMethodException, IllegalAccessException, IllegalArgumentException, InvocationTargetException{
        Field[] field = obj.getClass().getDeclaredFields();        //获取实体类的所有属性，返回Field数组  
        for(int j=0 ; j<field.length ; j++){     //遍历所有属性
                String fname = field[j].getName();    //获取属性名称
                
                System.out.println("attribute fname:"+fname);     
                fname = fname.substring(0,1).toUpperCase()+fname.substring(1); //将属性的首字符大写，方便构造get，set方法
                String ftype = field[j].getGenericType().toString();    //获取属性的类型
                if(ftype.equals("class java.lang.String")){   //如果ftype是类类型，则前面包含"class "，后面跟类名
                    Method m = obj.getClass().getMethod("get"+fname);
                    String value = (String) m.invoke(obj);    //利用反射原理，调用getter方法获取属性值
                    if(value != null){
						//对属性值的操作逻辑（如改变编码）	
                        System.out.println("attribute value:"+value);
                    }
                }
                if(ftype.equals("class java.lang.Integer")){     
                    Method m = obj.getClass().getMethod("get"+fname);
                    Integer value = (Integer) m.invoke(obj);
                    if(value != null){
                        System.out.println("attribute value:"+value);
                    }
                }
                if(ftype.equals("class java.lang.Short")){     
                    Method m = obj.getClass().getMethod("get"+fname);
                    Short value = (Short) m.invoke(obj);
                    if(value != null){
                        System.out.println("attribute value:"+value);                    }
                }       
                if(ftype.equals("class java.lang.Double")){     
                    Method m = obj.getClass().getMethod("get"+fname);
                    Double value = (Double) m.invoke(obj);
                    if(value != null){                    
                        System.out.println("attribute value:"+value);  
                    }
                }                  
                if(ftype.equals("class java.lang.Boolean")){
                    Method m = obj.getClass().getMethod("get"+fname);    
                    Boolean value = (Boolean) m.invoke(obj);
                    if(value != null){                      
                        System.out.println("attribute value:"+value);
                    }
                }
                if(ftype.equals("class java.util.Date")){
                    Method m = obj.getClass().getMethod("get"+fname);                    
                    Date value = (Date) m.invoke(obj);
                    if(value != null){
                        System.out.println("attribute value:"+value.toLocaleString());
                    }
                }                
            }
    }
