Several approaches to persistence have been discussed and the choice of one over the other is rationalized with regard to object-oriented methodology.West Virginia University.;Vangari, Srinivas S.West Virginia University.
Feign在默认情况下使用的是JDK原生的URLConnection发送HTTP请求,没有连接池,但是对每个地址会保持一个长连接,即利用HTTP的persistence connection。 在生产环境中,通常不使用默认的http client,通常有如下两种选择: 使用ApacheHttpClient 使用OkHttp 那么如何替换掉呢?其实很简单,下面演示使用ApacheHttpClient替换。 1、添加A...

AsyncRequestPersistence类的实例变量delegate相当于Active Object模式中的Servant参与者实例。 AsyncRequestPersistence类的store方法利用匿名类生成一个java.util.concurrent.Callable实例methodRequest。该实例相当于Active Object模式中的MethodRequest参与者实例。利用闭包(Closure),该实例封装了对store方法调用的上下文信息(包括调...
JPA (Java Persistence API )是Java的持久化API,用于对象的持久化。它是一个非常强大的ORM持久化的解决方案,免去了使用JDBCTemplate开发的编写脚本工作。JPA通过简单约定好接口方法的规则自动生成相应的JPQL语句,然后映射成POJO对象。 JPA是一个规范化接口,封装了Hibernate的操作作为默认实现,让用户不通过...

Combining memory objects that are spooled to a local disk with the distributed feature from the DISTRIBUTE attribute provides object persistence (when the Java Object Cache is running in distributed mode). Object persistence allows objects to survive the restarting of the JVM. Disk Objects Disk ...
