JAX-RPC AXIS 1实现了这种RPC的方式，基于SOAP,WSDL. AXIS 1是web service的一种实现方式？ AXIS 2采用了JAX-WS 2. websphere SOA的三个概念有: WPS(Websphere Process Server,这个我开始老是搞错，以为是portal server); ESB; WSRR(Websphere Service Registry Repository) WID(WebSphere Integration Developer)用来开发SCA,ESB的平台。因为SOA的这些东东RAD(Rational Applicaiton Developer)是搞不定的。 同样这些SOA的组件需要在WebSphere Process Server下跑。WAS下是跑不动的。不过止今还没见过WPS,WID这些神兵利器。也就玩玩WAS，RAD了，还是在公司。：<
get/load区别 如果记录存在，get返回对象（或代理对象）；否则返回null。 如果记录存在，load返回对象；否则返回 NotObjectFoundException 2.hibernate Cache 2.1 一级缓存，在当前session内 2.2 Query Cache Cache queries and results. 方法： 1. 在hiberante Configuration 文件中： true 2. 查询时 Query query = session.createQuery("from Person p where p.id=1"); query.setCacheable(true); 2.3 二级缓存, 跨session . 如EHCache 3. load 与 CreateQuery 在处理Cache的区别 首先,load时在一个session中，一级缓存总是有效的。比如下面的只issue sql操作一次 Session session = getSessionFactory().openSession(); Transaction tx = session.beginTransaction(); Person person1 = (Person) session.load(Person.class, 1L); System.out.println(person1.getFirstName()); Person person2 = (Person) session.load(Person.class, 1L); System.out.println(person2.getFirstName()); tx.commit(); session.close(); 其次,如果用CreateQuery有点不同，比若下面的需要issue sql操作两次 Session session = getSessionFactory().openSession(); Transaction tx = session.beginTransaction(); Query query = session.createQuery("from Person p where p.id=1"); Iterator it = query.list().iterator(); while (it.hasNext ()){ Person p = (Person) it.next(); System.out.println(p.getFirstName()); } query = session.createQuery("from Person p where p.id=1"); it = query.list().iterator(); while (it.hasNext ()){ Person p = (Person) it.next(); System.out.println(p.getFirstName()); } tx.commit(); session.close(); 原因是session cache时是根据key(load方法中传入的ID)来缓存的。解决的方法是： 1. 用load，如上面的代码 2. 用查询缓存，如上面的介绍 Session session = getSessionFactory().openSession(); Transaction tx = session.beginTransaction(); Query query = session.createQuery("from Person p where p.id=1"); query.setCacheable(true); Iterator it = query.list().iterator(); while (it.hasNext ()){ Person p = (Person) it.next(); System.out.println(p.getFirstName()); } query = session.createQuery("from Person p where p.id=1"); query.setCacheable(true); it = query.list().iterator(); while (it.hasNext ()){ Person p = (Person) it.next(); System.out.println(p.getFirstName()); } tx.commit(); session.close();
dirname 与 pwd pwd返回的是执行时当前路径 dirname 后面跟一个script文件参数，返回的是执行的script文件所在的路径 差别在于有时在一个目录路径下执行另一个路径下的script，这时这两个路径不同
