SPI(Service Provider Interface),是JDK内置的一种服务提供发现机制,可以用来启用框架扩展和替换组件,主要是被框架的开发人员使用,比如java.sql.Driver接口,其他不同厂商可以针对同一接口做出不同的实现,MySQL和PostgreSQL都有不同的实现提供给用户,而Java的SPI机制可以为某个接口寻找服务实现。Java中SPI机制主要思想是将...
Domain 目录服务器目录applications,将应用目录放在此目录下将可以作为应用访问,如果是Web应用,应用目录需要满足Web应用目录要求,jsp文件可以直接放在应用目录中,Javabean需要放在应用目录的WEB-INF目录的classes目录中,设置服务器的缺省应用将可以实现在浏览器上无需输入应用名。 85、在weblogic中发布ejb需涉及到哪些配置文件...

8)面对Array,我们可以直接持有基本型别数值的Array(例如:int [] num;),也可以持有reference(指向对象)的Array;但是容器类仅能持有reference(指向对象),若要将基本型别置于容器内,需要使用wrapper类。但是wrapper类使用起来可能不很容易上手,此外,primitives Array的效率比起“容纳基本型别之外覆类(的reference)”的容...
staticObjectget(Objectarray, int index) Returns the value of the indexed component in the specified array object. static booleangetBoolean(Objectarray, int index) Returns the value of the indexed component in the specified array object, as aboolean. ...
A typical strategy is to transform the name into a file name and then read a "class file" of that name from a file system. Every java.lang.Class Class object contains a Class#getClassLoader() reference to the ClassLoader that defined it. Class objects for array classes are not created ...
is supported across all of the AtomicX classes. For people who like to think of these operations in terms of machine-level barriers on common multiprocessors, lazySet provides a preceeding store-store barrier (which is either a no-op or very cheap on current platforms), but no store-load ...

Assert.isInstanceOf(Class clazz,Object obj,"clazz must be of type [clazz]")-obj必须能被正确造型成为clazz 指定的类 junit也提供断言工具类,但是我们只能在单元测试中使用,而Spring提供的这个,哪儿都能使用,还是比较方便的 PathMatcher 路径匹配器
Instances of the class Class represent classes and interfaces in a running Java application. An enum type is a kind of class and an annotation type is a kind of interface. Every array also belongs to a class that is reflected as a Class object that is shared by all arrays with the same...
