Question

我从头开始生成演示项目。该项目编译并开始时没有错误并发出警告。

但在应用 jhipster-entity-audit 后，我看到异常：

2018-01-17 03:46:54.194  WARN 128655 --- [demo-Executor-1] com.zaxxer.hikari.pool.ProxyConnection   : HikariPool-1 - Connection org.postgresql.jdbc.PgConnection@409be93d marked as broken because of SQLSTATE(08003), ErrorCode(0)

在应用jhipster-entity-audit时，我选择了：

Custom JHipster auditing (works with SQL)

JHipster版本：4.13.3

.yo-rc.json：

{
  "generator-jhipster": {
    "promptValues": {
      "packageName": "com.mycompany.myapp",
      "nativeLanguage": "en"
    },
    "jhipsterVersion": "4.13.3",
    "baseName": "demo",

    "enableTranslation": true,
    "nativeLanguage": "en",
    "languages": [
      "en"
    ]
  },
  "generator-jhipster-entity-audit": {
    "auditFramework": "custom"
  }
}

实体配置： 没有entityName.json文件

浏览器和操作系统 Linux Mint 18.3 Sylvia

npm -v
5.6.0
node -v
v8.9.4

请建议找到解决此问题的方法。

更新：我打开了问题：https://github.com/hipster-labs/generator-jhipster-entity-audit/issues/82

解决方法： 来自@ deepu105的提示解决方法只需添加字符串

cm.createCache(com.mycompany.myapp.domain.EntityAuditEvent.class.getName(), jcacheConfiguration);

到 CacheConfiguration.java 文件

Answer 1

当我使用IntelliJ运行dev时，我遇到了同样的问题。服务器。我不知道为什么，但我在这一步解决了这个问题：

使用maven手动构建测试，如果它是一个intelliJ错误（对我来说构建没问题）： ./mvnw
进入intellij并打开maven pannel：“view” - ＆gt; “工具窗口” - ＆gt; “maven project”
关于“个人资料”菜单处于活动状态且已停用且处于活动状态（再次）“IDE”个人资料（对我来说“dev”个人资料也有效）
现在，尝试使用intellij构建。

我有同样的问题。我意识到这是因为我使用OAuth2的决定。然后，我使用HTTP会话身份验证创建了一个新的jhipster项目，然后再次运行该项目。没关系。祝你好运
