你能推荐最好的jQuery multiselect插件吗？我需要预测搜索功能以及多选.预测搜索功能会很方便,因为下拉列表包含很长的值列表.

在尝试将消息发布到spring bean的init-method中的通道时,获取'Dispatcher没有订阅者'错误.请看下面的例子:

applicationContext.xml中

        request-channel="currencyChannel" remote-channel="currencyServiceChannel"
        reply-channel="currencyReplyChannel" host="localhost" port="2197" />

Spring托管bean:

每次触发我的构建工作流程时，都会下载Maven依赖项。

Travis CI提供了一种缓存Maven存储库的方法。Github操作是否提供允许缓存Maven存储库的类似功能？

调用/actuator/auditevents端点时出现 404 错误。仔细观察，我发现可用端点列表不包括/auditevents端点。

在谷歌代码上提供的ehcache-spring-annotations库中,可以使用配置选项"create-missing-caches"来动态创建动态缓存(未在ehcache.xml中定义缓存).纯弹簧ehcache抽象(Spring 3.1.1)中是否有类似的配置？或者有没有其他方法可以使用spring ehcache抽象创建动态缓存？

下面是我的nodejs代码

const express = require('express');

const app = express();

app.use('/', (req, res, next) => {
    console.log("In interceptor");
    next();
});

app.use('/users', (req, res, next) => {
    console.log('In /users middleware');
    res.send('<h1>From "/users" handler </h1>');
});

app.use('/', (req, res, next) => {
    console.log("Default handler");
    res.send('<h1>From default handler</h1>');
});

app.listen(3000);

从浏览器（chrome 和 Edge）发出请求时的控制台输出

http://localhost:3000
******************
In interceptor
Default handler
In interceptor
Default handler
******************

http://localhost:3000/users
******************
In interceptor
In /users middleware
In interceptor
Default handler
******************

但是当使用发出请求时curl，我没有看到多次调用

curl http://localhost:3000
