Spring-----2, Spring download and installation

I. Using spring in JAVASE applications

1. Download spring (download 1)

Download: Spring-frameword-3.05.release-with-docs.zip (Spring framework and documentation) + Spring-frameword-3.0.5.release-dependencies.zip ( The spring framework compiles and runs dependent third-party class libraries)

SPRING-FRAMEWORD-3.05.RELEASE-WITH-DOCS.ZIP directory structure:

Dist: Contains the Spring jar package, consists of 20 modules of the jar package, different jar packages provide different functions, the general core container corresponding jar package is the use of spring must

Docs: Documents that store spring, including development guides, API reference documents

Projects: Project structure for storing spring sub-modules, including project source code, MAVEN build file, Ant+lvy makefile

SRC: Project source code containing the spring modules; The source of each jar package containing a sub-module of the project

Other license and project-related documents on spring

2. Copy the jar package for the required modules in the Dist directory to the project Classpath path, and publish the jar packages together if you want to publish the app, and if there are not too many constraints, it is recommended that you copy all the jar packages in the Dist directory

3. Unzip the Spring-frameword-3.0.5.release-dependencies.zip; This directory contains the third-party class libraries on which the spring framework compiles and runs, depending on the project used by the application, and which jar files are required, usually by adding common-loggin Jar files in folders such as G

Ii. using spring in Web applications

Copy all jar packages under the dist path of the spring project to the Web App Web-inf/lib path

Copy the required third-party class library under spring's Spring-framework-3.0.5.release-dependencies.zip decompression path to the Web App Web-inf/lib path

Iii. developing spring applications in eclipse

New User library adds spring support for this project

Write the main program, the main program only initializes the spring container, the spring container is the core of the spring application, which manages the Java components in the container public class Springtest {public static void main (                String[] (args) {//Read the configuration file create a spring container The bean component that creates the Bean:spring container in spring is created and initialized when the container is created and instantiated       ApplicationContext context = new Classpathxmlapplicationcontext ("Bean.xml");             ApplicationContext context = new Filesystemxmlapplicationcontext (//"beans.xml");       Resource Resource = new Classpathresource ("Beans.xml");             Beanfactory context = new xmlbeanfactory (Resource);             Output Spring container System.out.println (context);       Get Personservice p = Context.getbean ("Personservice", Personservice.class) through the spring container;    P.info (); The}}applicationcontext instance is the spring container, which is the core of spring and is a huge, powerful factory; Once you get the spring container, It is up to the container to access the Beanspring container in the spring container without forcing the managed component to be the standard JavaBean spring container based on the profile information, responsible for creating the Personservice instance, and set property values for it-----the way that the spring container sets properties for an object is called inversion of control (inversion of CONTROL,IOC)

public class Personservice {    private String name;       Omit name Setter, getter method public       void info () {       System.out.println ("This person is named:" + name);}    }
