java框架-----spring框架------spring概述

 

1.spring框架（概述）

 

1. • Spring框架中可用的功能模塊有：（spring官網參考資料）
   • Dependency Injection（IoC）
   • Aspect-Oriented Programming including Spring's declarative transaction management（AOP）
   • Spring MVC web application and RESTful web service framework
   • Foundational support for JDBC, JPA, JMS
   • Much more…
   • All avaible features and modules are described in the Modules section of the reference documentation. Their maven/gradle coordinates are also described there.
   • 　　

   •  

     　　
2. 構成spring框架的全部模塊
   • The Spring Framework consists of features organized into about 20 modules. These modules are grouped into Core Container, Data Access/Integration, Web, AOP (Aspect Oriented Programming), Instrumentation, Messaging, and Test, as shown in the following diagram.　　

   • All avaible features and modules are described in the Modules section of the reference documentation. 

   • 在spring開發包中，上圖所示各個模塊被分開打包成「spring-模塊名稱-版本號.RELEASE.jar」，(e.g. spring-core-4.3.4.RELEASE.jar, spring-webmvc-4.3.4.RELEASE.jar, spring-jms-4.3.4.RELEASE.jar, etc.). 實際工程中，並不須要將spring的全部模塊都包含進你的工程，你能夠根據實際須要只選擇你的工程可以用到的那幾個模塊對應的jar包添加至你的工程中就能夠了。
   • 另外，spring框架的全部jar包以及spring框架所依賴的其餘jar包均可以在maven的中央倉庫找到，因此若是你的工程是使用maven進行管理的，那麼你的工程中引入spring時將會變得很是便捷：由於maven會自動從maven的中央倉庫下載你的項目所依賴的spring的jar包以及spring所依賴的其餘jar包到maven local repository中，
3. 如何使用spring

　　　　　　step1，明確spring是支持maven的

　　　　　　　　　　Each release of the Spring Framework will publish artifacts to the following places:

• • • • • Maven Central, which is the default repository that Maven queries, and does not require any special configuration to use. Many of the common libraries that Spring depends on also are available from Maven Central and a large section of the Spring community uses Maven for dependency management, so this is convenient for them. The names of the jars here are in the form spring-*-<version>.jar and the Maven groupId is org.springframework.
        • ArtifactId見下表

        • GroupId	ArtifactId	Description
          org.springframework	spring-aop	Proxy-based AOP support
          org.springframework	spring-aspects	AspectJ based aspects
          org.springframework	spring-beans	Beans support, including Groovy
          org.springframework	spring-context	Application context runtime, including scheduling and remoting abstractions
          org.springframework	spring-context-support	Support classes for integrating common third-party libraries into a Spring application context
          org.springframework	spring-core	Core utilities, used by many other Spring modules
          org.springframework	spring-expression	Spring Expression Language (SpEL)
          org.springframework	spring-instrument	Instrumentation agent for JVM bootstrapping
          org.springframework	spring-instrument-tomcat	Instrumentation agent for Tomcat
          org.springframework	spring-jdbc	JDBC support package, including DataSource setup and JDBC access support
          org.springframework	spring-jms	JMS support package, including helper classes to send and receive JMS messages
          org.springframework	spring-messaging	Support for messaging architectures and protocols
          org.springframework	spring-orm	Object/Relational Mapping, including JPA and Hibernate support
          org.springframework	spring-oxm	Object/XML Mapping
          org.springframework	spring-test	Support for unit testing and integration testing Spring components
          org.springframework	spring-tx	Transaction infrastructure, including DAO support and JCA integration
          org.springframework	spring-web	Web support packages, including client and web remoting
          org.springframework	spring-webmvc	REST Web Services and model-view-controller implementation for web applications
          org.springframework	spring-webmvc-portlet	MVC implementation to be used in a Portlet environment
          org.springframework	spring-websocket	WebSocket and SockJS implementations, including STOMP support

        • 若是你決定使用maven管理你的軟件工程，那麼如何使用maven爲你的項目自動添加spring框架的相關jar包呢？詳細教程參見以下連接：使用maven爲個人項目添加spring相關jar包
        • So the first thing you need to decide is how to manage your dependencies: we generally recommend the use of an automated system like Maven, Gradle or Ivy, but you can also do it manually by downloading all the jars yourself.
