利用反射遍历一个POJO对象的各个字段名及属性。。。

java 代码

public class ReflectionFiledPrintTest {
    private String name = "GoGoGo";

    private String city = "DoDoDo";

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public static void main(String args[]) {
        Object obj = "222";
        System.out.println("111"+obj);
        ReflectionFiledPrintTest tfpt = new ReflectionFiledPrintTest();
        try {
            Class reClass = Class
                    .forName("reflection.ReflectionFiledPrintTest");
            Method methods[] = reClass.getDeclaredMethods();
            for (int i = 0; i < methods.length; i++) {
                if (methods[i].getName().startsWith("get")) {
                    Object retobj = methods[i].invoke(tfpt, null);
                    System.out.println(methods[i].getName() + "="
                            + (String) retobj);
                }
            }
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        } catch (InvocationTargetException e) {
            e.printStackTrace();
        }
    }
}
