我有一个Entity Transaction如下:
@Entity
class Transaction extends AbstractEntity<Long>{
private static final long serialVersionUID = 7222139865127600245L;
//other attributes
@ElementCollection(fetch = FetchType.EAGER, targetClass = java.lang.String.class)
@CollectionTable(name = "transaction_properties", joinColumns = @JoinColumn(name = "p_id"))
@MapKeyColumn(name = "propertyKey")
@Column(name = "propertyValue")
private Map<String, String> properties;
//getters and setters
}
所以,我的数据库Table为transaction_properties是
mysql> desc transaction_properties;

| Field | Type | Null | Key | Default | Extra |

我正在使用 Oracle 数据库。
我需要在我的网络服务器上安装此功能.此错误消息正在寻找/usr/share/phpCOLON/usr/share/pear
我的php安装在/usr/share/php5,我没有/usr/share/pear文件夹
冒号在那个语法中意味着什么,"和"？
如果路径错误我不知道如何在此脚本中更改,我不想更改share/php5为php,或者是推荐的？
我正在使用play 2.2.2.
我想jdbc在Play/Scala项目中启用库,如访问SQL数据库中所述.
这是我的rootproject/project/plugins.sbt:
libraryDependencies ++= Seq(
jdbc
"com.google.zxing" % "core" % "2.0",
"mysql" % "mysql-connector-java" % "5.1.27",
"com.typesafe.slick" %% "slick" % "2.1.0",
"org.slf4j" % "slf4j-nop" % "1.6.4"
)
在编译项目时,我得到以下jdbc未找到的错误,

我试图使用clojure kORMa与compojure,webapp在这里nepleaks.
首先,我添加了kORMa依赖
[korma "0.3.0-RC4"]
lein deps很酷,然后创建src/hotel/conf/datasource.clj,如下所示:
(ns hotel.conf.datasource)
(use [korma.db])
(use [korma.core])
)
(defdb db (mysql {:db "nepleaks"
:user "root"
:password "mysql55"}))
(defentity users)
lein ring server 既没有抛出任何异常也没有创建数据库实体.
我错过了什么吗？我需要更多配置吗？
我想在gwt-localeSpring的帮助下设置用户选择的语言环境LocaleContextHolder.
public static final String getCurrentLocale() {
return LocaleContextHolder.getLocale().getLanguage();
}
我实际上在Spring MVC和内部Dashboard中有登录界面gwtp.在登录之前必须在外部接口中选择相同的区域设置用户gwt.
不幸的是,我没有看到任何gwt内置的Locale setter.
