小编Rad*_*ski的帖子

我通过使用Spring和Hibernate为服务创建实体,服务和JUnit测试来启动我的项目.所有这一切都很棒.然后我添加了spring-mvc来使用许多不同的分步教程来创建这个Web应用程序,但是当我尝试使用@Autowired注释创建Controller时,我在部署期间遇到来自Glassfish的错误.我想由于某些原因Spring没有看到我的服务,但经过多次尝试后我仍然无法处理它.

服务测试

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:/beans.xml"})

和

@Autowired
MailManager mailManager;

工作正常.

没有@Autowired的控制器,我可以毫无困难地在Web浏览器中打开我的项目.

公开节点包模块的标准方法是将它们列在index.ts中，如下所示：

export * from './module1';
export * from './module2';

但是，这会立即加载两个模块的内容。我想要一个未在 index.ts 文件中导出的模块，因为它需要安装一些可选的依赖项。

我遵循了本指南：https://blog.mozilla.org/data/2021/04/07/this-week-in-glean-publishing-glean-js/

我的package.json：

  "exports": {
    ".": {
      "import": "./dist/es/index.js",
      "require": "./dist/cjs/index.js"
    },
    "./module2": {
      "import": "./dist/es/module2.js",
      "require": "./dist/cjs/module2.js"
    }
  },
  "typesVersions": {
    "*": {
      ".": [
        "./dist/types/index.d.ts"
      ],
      "./module2": [
        "./dist/types/module2.d.ts"
      ]
    }
  },
// fallback for older Node versions:
  "module": "dist/es/index.js",
  "main": "dist/cjs/index.js",
  "types": "dist/types/index.d.ts",

在我构建项目后（使用tsc，分别用于 CJS 和 ESM），输出目录结构如下所示：

- dist
  - cjs
    - index.js
    - module2.js
  - es
    - index.js
    - module2.js
  - types …

我正在使用Java SE应用程序开发,使用Hibernate 4和c3p0与MariaDB数据库进行通信.它是长时间运行的应用程序,等待来自外部的信号,因此有时数据库会在8小时不活动后关闭我的连接.我试图配置c3p0连接验证,但它不起作用.你可以帮帮我吗？

我在Symfony2项目中使用了可缓慢的行为,但现在我想基于不同的文本(当前标题,旧标题,来自表单输入的用户文本)为一页制作许多slug,并将其保存在另一个页面中表.我的问题是 - 如何手动使用任何文本的学说扩展？我找不到任何地方.完美将是这样的:

/* careful - it's not a real, working code! */
$sluggable = new DoctrineSluggable();
$slug = $sluggable->generate('My own text!');
echo $slug; // my-own-text

我在OVH上有VPS,让我们说它是vpsXXXX.ovh.net,使用Debian 7.我已经安装了Java 8,Glassfish 4.1并启用了安全管理:

asadmin
> change-admin-password --user admin
> start-domain
> enable-secure-admin # user: admin
> restart-domain

我已经检查过vpsXXXX.ovh.net:8080和vpsXXXX.ovh.net:4848有效.当我通过scp上传我的战争时,通过SSH登录VPS并通过asadmin deploy JEE.war一切工作进行部署.

然后我取消部署它并尝试通过命令远程部署它:

asadmin --user admin --host vpsXXXX.ovh.net --port 4848 --secure deploy JEE.war

我给了管理员密码,经过很长一段时间(30秒？),我得到了:

remote failure: Request failed.
Command deploy failed.

我在VPS上的server.log:

我知道Google上有很多类似的问题,但我从他们那里尝试了很多,没有任何帮助.我试图从Java EE 7 Tutorial 运行这个项目,并在部署期间遇到异常.然后我用Stateful Bean制作了一个简单的小项目,得到了同样的一个.

首先,这是战争项目.我的所有文件:

很简单吧？我正在使用Glassfish 4.0(build 89)(从存储库 - Linux安装)具有全默认配置和所有内容.我检查了pkg,我安装了glassfish-ejb包:
