示例1: setStaticFinalField
import sun.reflect.FieldAccessor; //导入方法依赖的package包/类
public static void setStaticFinalField(
Field field, Object value)
throws NoSuchFieldException, IllegalAccessException
{
// 获得 public 权限
field.setAccessible(true);
// 将modifiers域设为非final,这样就可以修改了
Field modifiersField =
Field.class.getDeclaredField(MODIFIERS_FIELD);
modifiersField.setAccessible(true);
int modifiers = modifiersField.getInt(field);
// 去掉 final 标志位
modifiers &= ~Modifier.FINAL;
modifiersField.setInt(field, modifiers);
FieldAccessor fa = reflection.newFieldAccessor(
field, false
);
fa.set(null, value);
}
示例2: setFailsafeFieldValue
import sun.reflect.FieldAccessor; //导入方法依赖的package包/类
public static void setFailsafeFieldValue(Field field, Object target, Object value)
throws NoSuchFieldException, IllegalAccessException {
// let's make the field accessible
field.setAccessible(true);
// next we change the modifier in the Field instance to
// not be final anymore, thus tricking reflection into
// letting us modify the static final field
Field modifiersField = Field.class.getDeclaredField("modifiers");
modifiersField.setAccessible(true);
int modifiers = modifiersField.getInt(field);
// blank out the final bit in the modifiers int
modifiers &= ~Modifier.FINAL;
modifiersField.setInt(field, modifiers);
FieldAccessor fa = ReflectionFactory.getReflectionFactory().newFieldAccessor(field, false);
fa.set(target, value);
}
示例3: setField
import sun.reflect.FieldAccessor; //导入方法依赖的package包/类
private static void setField(Field field, Object target, Object value) throws NoSuchFieldException, IllegalAccessException, IllegalArgumentException, InvocationTargetException, NoSuchMethodException, SecurityException {
field.setAccessible(true);
Field modifiersField = Field.class.getDeclaredField("modifiers");
modifiersField.setAccessible(true);
modifiersField.setInt(field, field.getModifiers() & ~Modifier.FINAL);
FieldAccessor fieldAccessor = ReflectionFactory.getReflectionFactory().newFieldAccessor(field, true);
fieldAccessor.set(target, value);
}
示例4: setFailSafeFieldValue
import sun.reflect.FieldAccessor; //导入方法依赖的package包/类
