在Java中如何比较两个对象浅析

DiffBuilder(final T lhs, final T rhs,
        final ToStringStyle style)

public class Person implements Diffable<Person> {

    private static final Logger log = LoggerFactory.getLogger(Person.class);

    String name;
    int age;
    boolean smoker;

    public DiffResult diff(Person obj) {
        // No need for null check, as NullPointerException correct if obj is null
        return new DiffBuilder(this, obj, ToStringStyle.SHORT_PREFIX_STYLE)
                .append("name", this.name, obj.name)
                .append("age", this.age, obj.age)
                .append("smoker", this.smoker, obj.smoker)
                .build();
    }

    public static void main(String[] args) {
        Person a = new Person();
        a.name = "deniro";
        a.age = 22;
        a.smoker = false;

        Person b = new Person();
        b.name = "jack";
        b.age = 22;
        b.smoker = true;

        DiffResult result = a.diff(b);
        log.info("result -> {}。", result);
    }
}

Class c = Class.forName("包.类名称");

Field[] fields = c.getDeclaredFields();

setAccessible(true);

f.getField(对象名称)；

fields[j].getName()

fields[j].get(obj)
