我在一家大型健康保险公司工作,我们在后端大量使用 Spring。我将向您展示如何构建模块化应用程序。
骨架 WEB-INF没有类目录
ar
WEB-INF
web.xml
/**
* Spring related settings file
*/
ar-servlet.xml
web
moduleA
account
form.jsp
moduleB
order
form.jsp
骨架 类目录
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
...
注意br.com.ar.web 匹配 WEB-INF/view 目录下的每个包。这是在 Spring MVC 中运行约定优于配置所需的关键。如何 ???靠ControllerClassNameHandlerMapping
WEB-INF/ar-servlet.xml 注意 basePackage 属性,这意味着在 br.com.ar.view 下查找任何 @Controller 类em> 包。此属性允许您构建模块化的@Controller
<!--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>
现在让我们看看,例如,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);
}
}
它是如何工作的???
假设您请求http://127.0.0.1:8080/ar/moduleA/account/form.html
Spring 将删除 在 上下文路径和文件扩展名之间的路径 - 上面突出显示。让我们读取提取的路径从右到左
翻译成
br.com.ar.web.moduleA.AccountController.form
好的。但是 Spring 怎么知道要显示哪个视图???见here
关于持久性相关的问题???
首先,请参阅here 我们如何实现存储库。 请注意,每个相关的模块查询都存储在其相关的存储库包中。见上面的骨架。这里显示 ar-persistence.xml 注意 mappingLocations 和 packagesToScan 属性
<?xml version="1.0" encoding="UTF-8"?>

<prop key="hibernate.validator.autoregister_listeners">false</prop>

</property>

</beans>
请注意,我正在使用 Hibernate。应该正确配置 JPA。
事务管理和组件扫描 ar-service.xml 注意aop:pointcut的表达式属性br.com.ar后面的两个点意思是
br.com.ar包下的任何包和子包

测试
要测试带注释的@Controller 方法,请参阅here 如何
网页层除外。请注意我如何在 @Before 方法中配置 JNDI 数据源
@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);
}
}
如果您需要一套测试,请执行以下操作
@RunWith(Suite.class)
@Suite.SuiteClasses(value={AccountRepositoryIntegrationTest.class})
public void ModuleASuiteTest {}
web.xml如下所示

我希望它有用。将架构更新到 Spring 3.0。请参阅 Spring 参考文档。据我所知,仅在 Spring 3.0 中支持 mvc 模式。记住这一点

看看Apache CXF。它使用 Spring。
