The JMS API does not architect a reason for using multiple connections; however, there may be operational reasons for doing so. A JMS client typically creates a connection, one or more sessions, and a number of message producers and consumers. When a connection is created, it is in ...
RestTemplate是执行HTTP请求的同步阻塞式的客户端,它在HTTP客户端库(例如JDK HttpURLConnection,Apache HttpComponents,okHttp等)基础封装了更加简单易用的模板方法API。也就是说RestTemplate是一个封装,底层的实现还是java应用开发中常用的一些HTTP客户端。但是相对于直接使用底层的HTTP客户端库,它的操作更加方便、快捷,能...
使用JDBC 2.1 核心 API 创建的新Connection对象有一个与之关联的最初为空的类型映射。用户可以为此类型映射中的 UDT 输入一个自定义映射关系。在使用ResultSet.getObject方法从数据源中获取 UDT 时,getObject方法将检查该连接的类型映射是否有对应该 UDT 的条目。如果有,那么getObject方法将该 UDT 映射到所指示的类。
A new Connection object created using the JDBC 2.1 core API has an initially empty type map associated with it. A user may enter a custom mapping for a UDT in this type map. When a UDT is retrieved from a data source with the method ResultSet.getObject, the getObject method will check...
In many cases this value will be the actual baud rate, but baud rates higher than 19200 will correspond to lower values in the enumeration since the property is represented as a 16 bit integer. Product Availability Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server. Supported ...

To use such connections in applications, we provide the secure connection factory (class: SecureConnectionFactory). Although the secure connection factory’s primary purpose is to provide the framework to set up HTTPS connections where the AS Java is the client component, you can also use the ...
