我需要创建一个接受要包装的整数的构造函数。我目前有：
public class IntegerRateable implements Rateable {
private Integer object;
public IntegerRateable(Integer object) {
this.object = new Integer(object);
}
我不确定我的代码有什么问题。我的印象是这应该允许它被包裹。

如果你想要的是，你的<script src="https://unpkg.com/vue"></script>
<div id="app">
<p v-html="$options.filters.json(message)"></p>
<p :inner-html.prop="message | json"></p>
<p v-html="jsonMethod(message)"></p>
</div>类包含一个Integer作为成员变量，试试这个：
IntegerRateable然后，只需将public class IntegerRateable implements Rateable {
private Integer object;
public IntegerRateable (int number) {
this.object = number;
}
对象实例化为：

You may first want to check your braces, you're missing a closing brace #include <stdio.h>
#include <signal.h>
#include <errno.h>
#include <stdlib.h>
#include <time.h>
#include <string.h>
#include <unistd.h>
#include <sys/types.h>
#include <assert.h>
#include <sys/wait.h>
/* 24h = 24 * 60 * 60*/
#define TIMER_FREQUENCY 86400
void timer_expired(int sig)
{
// use this handler
}
int main(void)
{
struct sigaction act;
clockid_t clock_id;
timer_t timer_id;
struct sigevent clock_sig_event;
struct itimerspec timer_value;
int ret;
/* Register new action for SIGUSR1 */
memset(&act, 0, sizeof(struct sigaction));
act.sa_handler = timer_expired;
ret = sigaction(SIGUSR1, &act, NULL);
assert(ret == 0);
clock_id = CLOCK_MONOTONIC;
memset(&clock_sig_event, 0, sizeof( struct sigevent));
clock_sig_event.sigev_notify = SIGEV_SIGNAL;
clock_sig_event.sigev_signo = SIGUSR1;
clock_sig_event.sigev_notify_attributes = NULL;
/* Creating process interval timer */
ret = timer_create(clock_id, &clock_sig_event, &timer_id);
assert(ret == 0);
/* setitng timer interval values */
memset(&timer_value, 0, sizeof(struct itimerspec));
timer_value.it_interval.tv_sec = TIMER_FREQUENCY;
timer_value.it_interval.tv_nsec = 0;
/* setting timer initial expiration values*/
timer_value.it_value.tv_sec = TIMER_FREQUENCY;
timer_value.it_value.tv_nsec = 0;
/* Create timer */
ret = timer_settime(timer_id, 0, &timer_value, NULL);
assert(ret == 0);
/* Now we have a timer with following features:
* It will expire after 24 hours and excute fucntion timer_expired
* upon expiration */
/*
* Do something here
*
* To test, sleep() for 5 sec and set timer expiry as 1 sec i.e.
* TIMER_FREQUENCY as 1.
* In this case first timer will expire after 1 sec and sleep will
* come out, also timer_expired() will be executed. Later time will expire after every 1 sec.
*
* We can also use SIGEV_THREAD instead of SIGEV_SIGNAL in clock_sig_event.sigev_notify
* while creating timer_id using timer_create().In that case we need to check for other parameter
* as well.

If that's not the problem, I'am assuming that the problem is in this line
} . There is nothing wrong with this, it's just that it using the Integer constructor has been deprecated which you can find out more about here https://docs.oracle.com/javase/9/docs/api/java/lang/Integer.html#Integer-int-
So the preferred way of doing it would be to do this.object = new Integer(object);
EDIT: Although, I don't see a point in doing this since you can just do this.object = new Integer.valueOf(object);
