類:
public class Test {
private String name;
public String getName() {
return name;
}
public void setName( String name) {
this.name= name;
}
}
方法1：
Test t = new Test();
Field f = t.getClass().getDeclaredField("name");
f.setAccessible(true);
f.set(t, "this is test1");
System.out.println(t.getName());
方法2：
Test t = new Test();
Method setName = t.getClass().getMethod("setName", String.class);
String s ="this is test2";
setName.invoke(t,s);
System.out.println(t.getName());
