1、黑龍江工程學(xué)院本科生畢業(yè)設(shè)計外文文獻翻譯SpringFrameworkSpring is an open source framework, and Spring was launched in 2003 as a lightweight Java development framework created by Rod Johnson. In a nutshell, Spring is a hierarchical, JavaSE/E

2、Efull-stack (one-stop) lightweight open source framework. The powerful JavaBeans based configuration management using the Inversion of Control (IoC) principle makes application components faster and easier.1. facilitate

3、decoupling and simplify developmentThrough the IoC container provided by Spring, we can control dependencies between objects by Spring, avoiding excessive program coupling caused by hard coding. With Spring, users do not

4、 have to write code for the bottom tier requirements of single instance schema classes, properties, file parsing, and so on, and can focus more on top tier applications.2.AOP programming supportThrough the Spring functio

5、nality provided by AOP, it is easy to implement face oriented programming, and many features that are not easily implemented with traditional OOP can be easily handled by AOP.3. declarative transaction supportIn Spring,

6、we can extricate ourselves from tedious and tedious transaction management code and flexibly manage the transaction through declarative manner, so as to improve the efficiency and quality of development.4. convenience pr

7、ogram testingAlmost all test work can be done in a non container dependent programming manner, and in Spring, testing is no longer expensive, but something to do. For example, Spring supports Junit4 and can easily test S

8、pring programs by annotations.5. convenient integration of various excellent frameworkSpring does not exclude all kinds of excellent open source framework, on the contrary, Spring can reduce the difficulty of the use of

9、Spring framework, provides a framework for a variety of excellent (such as Struts, Hibernate, Hessian, Quartz) directly support the.6. reduce the difficulty of using Java EE APISpring provides a thin layer of encapsulati

12、里，測試不再是昂貴的操作，而是隨手可做的事情。例如：Spring 對 Junit4 支持，可以通過注解方便的測試 Spring 程序。5.方便集成各種優(yōu)秀框架Spring 不排斥各種優(yōu)秀的開源框架，相反，Spring 可以降低各種框架的使用難度，Spring 提供了對各種優(yōu)秀框架（如 Struts,Hibernate、Hessian、Quartz）等的直接支持。6.降低 Java EE API 的使用難度Spring 對很多難用的 Ja

13、va EE API（如 JDBC，JavaMail，遠程調(diào)用等）提供了一個薄薄的封裝層，通過 Spring 的簡易封裝，這些 Java EE API 的使用難度大為降低。7.Java 源碼是經(jīng)典學(xué)習(xí)范例Spring 的源碼設(shè)計精妙、結(jié)構(gòu)清晰、匠心獨運，處處體現(xiàn)著大師對 Java 設(shè)計模式靈活運用以及對 Java 技術(shù)的高深造詣。Spring 框架源碼無疑是 Java 技術(shù)的最佳實踐范例。如果想在短時間內(nèi)迅速提高自己的 Java 技術(shù)水平

14、和應(yīng)用開發(fā)水平，學(xué)習(xí)和研究 Spring 源碼將會使你收到意想不到的效果。MVC——Spring 的作用是整合，但不僅僅限于整合，Spring 框架可以被看做是一個企業(yè)解決方案級別的框架?？蛻舳税l(fā)送請求，服務(wù)器控制器（由 DispatcherServlet 實現(xiàn)的)完成請求的轉(zhuǎn)發(fā)，控制器調(diào)用一個用于映射的類 HandlerMapping，該類用于將請求映射到對應(yīng)的處理器來處理請求。HandlerMapping 將請求映射到對應(yīng)的處理器

15、Controller（相當(dāng)于 Action）在 Spring 當(dāng)中如果寫一些處理器組件，一般實現(xiàn)Controller 接口，在 Controller 中就可以調(diào)用一些 Service 或 DAO 來進行數(shù)據(jù)操作 ModelAndView 用于存放從 DAO 中取出的數(shù)據(jù)，還可以存放響應(yīng)視圖的一些數(shù)據(jù)。 如果想將處理結(jié)果返回給用戶，那么在 Spring 框架中還提供一個視圖組件ViewResolver，該組件根據(jù) Controller
