Any open source Spring sample project that's bigger than PetClinic? [closed]

spring spring-mvc open-source

I've finished reading the spring doc and the PetClinic sample project. Just like to see some bigger real world project that's done with Spring. Thanks.

Solution 2:

I work for a big health insurance company where we heavily use Spring in backend. I will show you how a modularized application is built.

Skeleton WEB-INF without classes directory

ar
    WEB-INF
        web.xml
        /**
          * Spring related settings file
          */
        ar-servlet.xml
        web
            moduleA
                account
                    form.jsp
            moduleB
                order
                    form.jsp

Skeleton classes directory

        classes
            /**
              * Spring related settings file
              */
            ar-persistence.xml
            ar-security.xml
            ar-service.xml
            messages.properties
            br
                com
                    ar
                        web
                            moduleA
                                AccountController.class        
                            moduleB
                                OrderController.class
            br
                com
                    ar
                        moduleA
                            model
                                domain
                                    Account.class
                                repository
                                    moduleA.hbm.xml
                                service
            br
                com
                    ar
                        moduleB
                            model
                                domain
                                    Order.class
                                repository
                                    moduleB.hbm.xml
                                service
            ...

Notice how each package under br.com.ar.web matchs WEB-INF/view directory. It is The key needed To run convention-over-configuration in Spring MVC. How to ??? rely on ControllerClassNameHandlerMapping

WEB-INF/ar-servlet.xml Notice basePackage property which means look for any @Controller class under br.com.ar.view package. This property allows you build modularized @Controller's

<!--Scans the classpath for annotated components at br.com.ar.web package-->
<context:component-scan base-package="br.com.ar.web"/>
<!--registers the HandlerMapping and HandlerAdapter required to dispatch requests to your @Controllers-->
<mvc:annotation-driven/>
<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping">
    <property name="basePackage" value="br.com.ar.web"/>
    <property name="caseSensitive" value="true"/>
    <property name="defaultHandler">
        <bean class="org.springframework.web.servlet.mvc.UrlFilenameViewController"/>
    </property>
</bean>
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/view/"/>
    <property name="suffix" value=".jsp"/>
</bean>

Now let's see, for instance, AccountController

package br.com.ar.web;

@Controller
public class AccountController {

    @Qualifier("categoryRepository")
    private @Autowired Repository<Category, Category, Integer> categoryRepository;

    @Qualifier("accountRepository")
    private @Autowired Repository<Account, Accout, Integer> accountRepository;

    /**
     * mapped To /account/form
     */
    @RequestMapping(method=RequesMethod.GET)
    public void form(Model model) {
        model.add(categoryRepository().getCategoryList());
    }

    /**
     * mapped To account/form
     */
    @RequestMapping(method=RequesMethod.POST)
    public void form(Account account, Errors errors) {
        accountRepository.add(account);
    }

}

How does it work ???

Suppose you make a request for http://127.0.0.1:8080/ar/moduleA/account/form.html

Spring will remove the path between context path and file extension - highlighted above. Let's read the extracted path from the right To the left

  • form method name
  • account unqualified class name without Controller suffix
  • moduleA package which will be added to basePackage property

which is translated to

br.com.ar.web.moduleA.AccountController.form

Ok. But how does Spring know which view to show ??? See here

And about persistence related issues ???

First of all, see here how we implement repository. Notice each related module query is stored at its related repository package. See skeleton above. Here is shown ar-persistence.xml Notice mappingLocations and packagesToScan property

Notice i am using Hibernate. JPA should be properly configured.

Testing

To test annotated @Controller method, see here how to

Other than web layer. Notice how i configure a JNDI dataSource in @Before method

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:ar-service.xml", "classpath:ar-persistence.xml"})
public class AccountRepositoryIntegrationTest {

    @Autowired
    @Qualifier("accountRepository")
    private Repository<Account, Account, Integer> repository;

    private Integer id;

    @Before
    public void setUp() {
         SimpleNamingContextBuilder builder = new SimpleNamingContextBuilder();
         DataSource ds = new SimpleDriverDataSource(new oracle.jdbc.driver.OracleDriver(), "jdbc:oracle:thin:@127.0.0.1:1521:ar", "#$%#", "#$%#");

         builder.bind("/jdbc/dataSource", ds);
         builder.activate();

         /**
           * Save an Account and set up id field
           */
    }

    @Test
    public void assertSavedAccount() {
        Account account = repository.findById(id);

        assertNotNull(account);
    }

}

If you need a suite of tests, do as follows

@RunWith(Suite.class)
@Suite.SuiteClasses(value={AccountRepositoryIntegrationTest.class})
public void ModuleASuiteTest {}

web.xml is shown as follows

I hope it can be useful. Update schema To Spring 3.0. See Spring reference documentation. mvc schema, As far As i know, is supported just in Spring 3.0. Keep this in mind

Solution 3:

Some candidates:

  • AppFuse - In AppFuse, the Spring Framework is used throughout for its Hibernate/iBATIS support, declarative transactions, dependency binding and layer decoupling.

  • Equinox (a.k.a. AppFuse Light) - a simple CRUD app created as part of Spring Live.

  • Spring by Example - Various Spring examples plus some downloadable libraries.

  • Tudu Lists - Tudu Lists is a J2EE application for managing todo lists. It's based on JDK 5.0, Spring, Hibernate, and an AJAX interface (using the DWR framework).

Solution 4:

Look at Apache CXF. It uses Spring.
