用反射吧，然后設置setAccessible為true就可以了，如下：public class Test {private?String?readOnly;

public?String?getReadOnly()?{

????return?readOnly;

}

public?static?void?main(String[]?args)?throws?SecurityException,?NoSuchFieldException,?IllegalArgumentException,?IllegalAccessException?{

????Test?t?=?new?Test();

????Field?f?=?t.getClass().getDeclaredField("readOnly");

????f.setAccessible(true);

????f.set(t,?"test");

????System.out.println(t.getReadOnly());

}}
