1. สปริงเฟรมเวิร์คเวิร์คชอป(Spring Framework Workshop) By www.spring66.com มิถุนายน 2553, 12 ชัดเจน “เขียนจาวาไม่ใช้สปริง บาป”

2. @roofimonขอ ขอบคุณTA ไม่มี TA ไม่มีงานนี้ครับ @somkiat พระ @9tae ไปบวชอยู่ @poorprogrammer @nuboat @YashimaExteen @boyone @siros_s มาสอน AOP ตอนบ่าย TA เป็นผู้ทรงคุณวุฒิเรื่องสปริงทุกท่าน

3. Agenda Impossible is nothing Why Spring? New Features and Enhancements in Spring 3.0 Core Container 3.0 Persistence with Spring JDBC AOP (@siros_s) EhCache(Apply AOP) Spring Web MVC with Web Annotation

4. Basic Requirements JDK 1.6 ++ Maven 2.0.x Apache Derby Netbeans, Eclipse, Vi, Whatever IDE Skeleton Source from http://code.google.com/p/spring66-training-3/svn/branches/1.0.PRE Full https://spring66-training-3.googlecode.com/svn/branches/1.9PRE

5. ที่มาของเนื้อหา(ลอกมาจากไหน) Building Spring2 Enterprise Application Development J2EE without EJB Professional Spring Framework Spring2 in Action Pro Spring2 Spring Recipe หนังสืออ้างอิงเยอะมาก

7. Spring provides comprehensive infrastructure support for developing Java applications

9. lightweight Container (Value Added) Transaction Thread management Object pooling Clustering Management Remoting Exposing remote services Consuming remote services Customization and extensibility AOP

10. ทำไมต้องสปริง เมื่อก่อน Java เตรียมเครื่องมือไว้ให้เยอะไปหมดแต่เวลาใช้ ? Design Pattern: ต้องนั่งตีความเอาเอง กระบวนการรวมฟีเจอร์ของ SUN โหดร้ายเกินไป ชีวิตเราถูกผูกติดกับ Application Server, API มากเกินไป อยากเอาฟีเจอร์มารวมกันพร้อมทั้งใช้ Design Pattern ด้วย ? Light Weight

11. สมัยนี้

13. Main Components

14. Layer of Application

15. Bean? Bean is a service Service = Interface+Implement+Descriptor Bean อาศัยอยู่ใน Bean Factory หรือ Application Context Application Context คือหัวใจของ Spring คิดไม่ออกต้องสร้าง Application Context ขึ้นมาก่อน

16. Configuration ส่วนมากจะชื่อ applicationContect.xml

17. Initial Context //Load Context Manually From AppConfig.class ApplicationContext context = new FileSystemXmlApplicationContext( "classpath:/applicationContext.xml"); //Lookup Bean named Clinic clinic = (Clinic)context.getBean(“clinic”); Collection<Vet> vets = clinic.getVets();

18. The “PetClinic”

19. The “Lightweight Container” Architecture

20. Basic Architecture Spring JDBC Spring Core Spring Web MVC JSP jQuery

21. Basic Requirement Use Cases View a list of veterinarians and their specialties View information pertaining to a pet owner Update the information pertaining to a pet owner Add a new pet owner to the system View information pertaining to a pet Update the information pertaining to a pet Add a new pet to the system View information pertaining to a pet's visitation history Add information pertaining to a visit to the pet's visitation history Business Rules An owner may not have multiple pets with the same case-insensitive name

22. Checkout Code from Google Code Create Test Case Call “isClinicServiceReady” @Autowired protected Clinic clinic; @Test public void isCliniceReady() { assertNotNull(clinic); } We have done creating our first “bean”.

23. Checkout Code from Google Code Create “interface Clinic” Run Test (Fail!!!!!) Create applicationContect.xml Copy content from “Master Project” “srcestesourcesrgpring66raining3estetclinicaseline” Run Test !!!!!! We have done creating our first “bean”.

24. What we have done?

25. Why Test First Test case is “META-CODE”, code that explains code. Feel confident for refactor, move and share.

26. Checkout Code from Google Code Create “interface ListDataService” Create “class ListDataServiceImpl” @Override public List getElementsList() { List list = new ArrayList(); list.add("Tom"); list.add("Henri"); list.add("Jim"); return list; }

27. Go more deep into “DataSource” DB Persistence Manager Oracle MsSQL DB2 MySQL Hibernate iBatis OpenJPA Connection Data Source

28. Go more deep into “DataSource” Basically we must have this information for datasource Driver Class Driver Class Name Connection String (URL) Username Password Plus some optional parameters depends on Driver Manager (Pool Size, Wait Time, bla bla bla)

29. Go more deep into DataSource Basically we must have this information <bean id="dataSource" class=“$Driver"> <!-- Connection Info --> <property name="driverClassName" value="${jdbc.driverClassName}" /> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <!-- Connection Pooling DBCP --> <property name="initialSize" value="5"/> <property name="maxActive" value="100" /> <property name="maxIdle" value="30" /> <property name="maxWait" value="1000" /> <property name="poolPreparedStatements" value="true" /> <property name="defaultAutoCommit" value="false" /> </bean>

30. Spring JDBC The value-add provided by the Spring Framework JDBC abstraction is perhaps best shown by the sequence of actions outlined in the table.

31. Spring JDBC

32. Go more deep into Spring JDBC JdbcTemplate NamedParameterJdbcTemplate SimpleJdbcTemplate SimpleJdbcInsert and SimpleJdbcCall RDBMS Objects including MappingSqlQuery, SqlUpdate and StoredProcedure

33. Go more deep into Spring JDBC DataSource Prepared Statement Mapper Extractor

34. Move up to Service Layer The most important part of our Application. All business logics are located, here Test it carefully, change very often. Controller Service Entity A Entity B Entity C

35. Spring Web MVC Flow Clear separation of roles Powerful and straightforward configuration of both framework and application classes as JavaBeans. Adaptability, non-intrusiveness, and flexibility. Customizable binding and validation Customizable handler mapping and view resolution Flexible model transfer Beans whose lifecycle is scoped to the current HTTP request or HTTP Session

36. Spring DispatcherServlet

37. Dispatcher Servlet <web-app> <servlet> <servlet-name>example</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>example</servlet-name> <url-pattern>*.form</url-pattern> </servlet-mapping> </web-app>

38. Example-servlet.xml <context:component-scan base-package="com.spring66.petclinic.web"/> <bean class="org.springframework.web.servlet.view.BeanNameViewResolver" p:order="0"/> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/jsp/" p:suffix=".jsp" p:order="1"/> <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource" p:basename="messages"/>

39. Context Hierarchy

45. And then Copy Content from Main Project

46. srcainavaompring66etcliniceb

47. ====ClinicController======

48. “mvn jetty:run –Dmaven.test.skip=true –Djetty.port=9999”

50. And then Copy Content from Web.text

51. ====TestVetController======

53. Create “VetController”

54. Copy content from “Web.txt”

55. Part “VetController”

56. There are two interesting parts:

57. Inject “clinic” service into controller

58. @Autowired

59. And Request Mapping

60. @Request over “public Collection<Vet> list()”

62. And then Copy Content from Web.text

63. ====TestOwnerController======

65. Copy content from “Web.txt”

66. Part “SearchOwnerController”

67. If it works so move forward

68. Do some magic by adding new Owner

69. Copy content from “Web.txt”

70. Part “AddOwnerController”

71. Create “ViewUtils”

72. Copy content from “Web.txt”

73. Part “ViewUtils”

74. Create “PageType”.. Good u can guest, next
