通过java反射获得属性名 和 值

网上查的, 稍微改了改

有空再好好改

public static void getAllFieldsName(Object model) throws NoSuchMethodException, IllegalAccessException, IllegalArgumentException, InvocationTargetException
{
Field[] field = model.getClass().getDeclaredFields();//获取实体类的所有属性，返回Field数组
for(int j=0 , len=field.length; j<len ; j++)//遍历所有属性
{
String name = field[j].getName();//获取属性的名字
System.out.println("attribute name:"+name);

String type = field[j].getGenericType().toString();//获取属性的类型
if(type.equals("class java.lang.String")){//如果type是类类型，则前面包含"class "，后面跟类名
Method m = model.getClass().getMethod("get"+firstUpperCase(name));
String value = (String) m.invoke(model);//调用getter方法获取属性值
if(value != null){
System.out.println("attribute value:"+value);
}
}
if(type.equals("class java.lang.Integer")){
Method m = model.getClass().getMethod("get"+firstUpperCase(name));
Integer value = (Integer) m.invoke(model);
if(value != null){
System.out.println("attribute value:"+value);
}
}
if(type.equals("class java.lang.Short")){
Method m = model.getClass().getMethod("get"+firstUpperCase(name));
Short value = (Short) m.invoke(model);
if(value != null){
System.out.println("attribute value:"+value);
}
}
if(type.equals("class java.lang.Double")){
Method m = model.getClass().getMethod("get"+firstUpperCase(name));
Double value = (Double) m.invoke(model);
if(value != null){
System.out.println("attribute value:"+value);
}
}
if(type.equals("class java.lang.Boolean")){
Method m = model.getClass().getMethod("get"+firstUpperCase(name));
Boolean value = (Boolean) m.invoke(model);
if(value != null){
System.out.println("attribute value:"+value);
}
}
if(type.equals("class java.util.Date")){
Method m = model.getClass().getMethod("get"+firstUpperCase(name));
Date value = (Date) m.invoke(model);
if(value != null){
System.out.println("attribute value:"+value.toLocaleString());
}
}
}
}
public static String firstUpperCase(String str)
{
return str.replaceFirst(str.substring(0, 1), str.substring(0, 1).toUpperCase()) ;
}
