PropertyUtils、BeanUtils的copyProperties()和set、get性能比较

A a1 = new A();
a1.setName("wang");
A a2 = new A();
long b = new java.util.Date().getTime();
a2.setName(a1.getName());
long e = new java.util.Date().getTime();
System.out.println("time1="+(e-b));
A a3 = new A();
b = new java.util.Date().getTime();
PropertyUtils.copyProperties(a3, a1);
e = new java.util.Date().getTime();
System.out.println("time2="+(e-b));
