Inversion of Control (IoC)

Inversion of Control (IoC)

The Spring Web MVC framework

Data access with JDBC

Unit and integration testing

Transaction management

basic inventory management system

springapp

project name as “springapp”

“springapp” as the dispatcher name

springapp/web/index.jsp

springapp/web/WEB-INF/web.xml

plugin users can ignore this section

springapp/web/WEB-INF

web.xml

Front Controller

springapp-servlet.xml

Page Controller

BeanNameUrlHandlerMapping

HelloController

springapp.web

Source Packages

HelloController.java

return new ModelAndView("hello.jsp");

In Spring Web MVC, the Controller handles the request and returns a ModelAndView

ViewResolver

Agile development

Test Packages

JUnit

HelloControllerTests

springapp/test/springapp/web/HelloControllerTests.java

jstl.jar

standard.jar

When we enter http://localhost:8080/springapp/ in a browser, it should pull up the welcome file 'index.jsp', which should redirect to 'hello.htm' and is handled by the DispatcherServlet, which in turn delegates our request to the page controller that puts the date and time in the model and then makes the model available to the view 'hello.jsp'.

SimpleUrlHandlerMapping

ResourceBundleViewResolver

set a prefix and a suffix on the InternalResourceViewResolver

Test-Driven Development (TDD)

ProductManager service

Product class

service responsible for handling products

getProducts()

increasePrice()

make it an interface instead of a concrete class

public interface ProductManager

It's usually a good idea to mark unimplemented methods by getting them to throw an UnsupportedOperationException

We rename HelloController to InventoryController and the HelloControllerTests to InventoryControllerTests.

not going to add any code to load the business objects from a database

we can stub a couple of Product instances using Spring's bean and application context support

messageSource

This form uses a tag library named 'spring-form.tld' that is provided with the Spring Framework. We have to copy this file from the Spring distribution ('spring-framework-2.5/dist/resources/spring-form.tld') to the 'springapp/web/WEB-INF/tld' directory that we also need to create

commandClass and validator

a formView that is used for the form and a successView that we will go to after successful form processing

regular view reference that is forwarded to one of our JSP pages

alternative way is to use a redirect, where a response is sent back to the users browser instructing it to redirect to a new URL

we need to add an entry in the 'springapp-servlet.xml' file to define the new form and controller.

hsqldb.jar

Data Access Object (DAO)

ProductDao

you won't have to catch any exceptions

JdbcProductDao

opening and closing the connection or any statements. It is all handled for you

Since we are extending SimpleJdbcSupport we get a SimpleJdbcTemplate prepared and ready to use.

getProductList() executes a query using the SimpleJdbcTemplate

ProductMapper implements the ParameterizedRowMapper interface that defines a single method named mapRow that must be implemented.

saveProduct is also using the SimpleJdbcTemplate

spring-test.jar

Spring provides an extensive testing framework that supports JUnit 3.8 and 4 as well as TestNG

AbstractTransactionalDataSourceSpringContextTests

dependency injection of any public setter from an application context

opportunity to prepare our database with the appropriate test data in the onSetUpInTransaction method

deleteFromTables and executeSqlScript methods

service layer

The pointcut applies to any method called on the ProductManager interface. The advice is a transaction advice that applies to methods with a name starting with 'save'. The default transaction attributes of REQUIRED applies since no other attribute was specified. The advice also applies "read-only" transactions on any other methods that are adviced via the pointcut.

DBCP connection pool

copy aspectjweaver.jar from the 'spring-framework-2.5/lib/aspectj' directory and commons-dbcp.jar and commons-pool.jar from the 'spring-framework-2.5/lib/jakarta-commons' directory

A namespace is the set of all possible names in a naming system.

"cn" for common name, "dc" for domain component, "mail" for e-mail address and "sn" for surname
