Spring Learning Note 1--spring Build

1. Create a new Java project 2. Add spring-related jar packages and add them to the reference 3. Add spring dependent jar packages and add them to the reference 4. Write Spring configuration file Applicationcontext.xmlCreate a new Applicationcontext.xml file, and then write the header file. For the spring header file, refer to the guide provided by spring. Unzip the downloaded spring file to finddocs\spring-framework-reference\html\index.htmland open, and then find in the open page there will be a header file related to the following is the written applicationcontext.xml file.

<?XML version= "1.0" encoding= "UTF-8"?><Beansxmlns= "Http://www.springframework.org/schema/beans"Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"xsi:schemalocation= "Http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd" >           <BeanID= "User"class= "domain. User ">< Propertyname= "Name"value= "Fei"/></Bean></Beans>

5, write the test program run SpringFirst, write a test of the entity class user

 Public classUser {PrivateString name; PublicString GetName () {returnname;}  Public voidsetName (String name) { This. Name =name;}  PublicUser (String name) { This. Name =name;}  PublicUser () {} Public voidSayname () {System.out.println (name);}}

Ii. writing the test file method one: Using the Spring test framework

@RunWith (Springjunit4classrunner.  Class)// Use Spring's test framework @ContextConfiguration ("Classpath:applicationContext.xml")//  Load the spring configuration file and load the configuration files placed in other folders:/config/applicationcontext.xmlpublicclass  springtest {  privatepublicvoid  test1 () {  User.sayname (); } }

Mode two: Load the spring configuration file with Classpathxmlapplicationcontext to implement ApplicationContext

 Public class SpringTest02 {  privatestaticstatic  {  new classpathxmlapplicationcontext ("Classpath:config/applicationcontext.xml" Public void test1 () {  Ctx.getbean ("user", user.  Class). Sayname (); }}
