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...

前言 在Spring Framework里的spring-core核心包里面,有个org.springframework.util里面有不少非常实用的工具类。 该工具包里面的工具类虽然是被定义在Spring下面的,但是由于Spring框架目前几乎成了JavaEE实际的标准了,因此我们直接使用也是无妨的,很多时候能够大大的提高我们的生产力。本文主要介绍一些个人认为还非常实用的...

Another nice feature of properties: if a developer uses Reflection, he can access these properties more easily in a generic way. It is possible to use non-standard set and get accessor functions, but the syntax of these functions must be well-defined and negotiated beforehand for this to ...
The default value of the limit can be changed by specifying a positive value with the jdk.http.maxHeaderSize system property on the command line, or in the $JAVA_HOME/jre/lib/net.properties file. A negative or zero value is interpreted as no limit. If the limit is exceeded, the request...

Retains flexibility by allowing Java libraries to define the formatting syntax used in string templates. Simplifies the use of APIs that accept strings written in non-Java languages (e.g., SQL, XML, and JSON). Enables the creation of non-string values computed from literal text and embedded ...
