请注意 br.com.ar.web 下的每个包如何匹配 WEB-INF / view 目录。它是在Spring MVC中运行约定优于配置所需的密钥。如何？？？依靠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 类包。此属性允许您构建模块化的@ Controller的

<!--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>

现在让我们看一下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将删除上面突出显示的上下文路径和文件扩展名之间的路径。让我们从右到左阅读提取的路径

表单方法名称

帐户不合格的班级名称不含控制器后缀

moduleA 包将被添加到 basePackage 属性

被翻译为

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

确定。但是Spring怎么知道哪个视图显示???见here

关于持久性相关问题???

首先，请参阅here我们如何实施存储库。 请注意，每个相关模块查询都存储在其相关的存储库包中。见上面的骨架。这里显示了ar-persistence.xml注意 mappingLocations 和 packagesToScan 属性

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.5.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-2.5.xsd"> <jee:jndi-lookup id="dataSource" jndi-name="jdbc/dataSource" resource-ref="true"> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="mappingLocations"> <util:list> <value>classpath:br/com/ar/model/repository/hql.moduleA.hbm.xml</value> <value>classpath:br/com/ar/model/repository/hql.moduleB.hbm.xml</value> </util:list> </property> <property name="packagesToScan"> <util:list> <value>br.com.ar.moduleA.model.domain</value> <value>br.com.ar.moduleB.model.domain</value> </util:list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect</prop> <prop key="hibernate.connection.charSet">UTF-8</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.format_sql">true</prop> <prop key="hibernate.validator.autoregister_listeners">false</prop> </props> </property> </bean> </beans>

注意我正在使用Hibernate。应正确配置JPA。

事务管理和组件扫描 ar-service.xml在aop中的 br.com.ar 之后注意两个点：pointcut的表达式属性装置

br.com.ar包下的任何包和子包

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd"> <context:component-scan base-package="br.com.ar.model">  <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"/> </bean> <tx:advice id="repositoryTransactionManagementAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="add" propagation="REQUIRED"/> <tx:method name="remove" propagation="REQUIRED"/> <tx:method name="update" propagation="REQUIRED"/> <tx:method name="find*" propagation="SUPPORTS"/> </tx:attributes> </tx:advice> <tx:advice id="serviceTransactionManagementAdvice" transaction-manager="transactionManager">  <tx:attributes> <tx:method name="*" propagation="REQUIRED"/> </tx:attributes> </tx:advice> <aop:config> <aop:pointcut id="servicePointcut" expression="execution(* br.com.ar..service.*Service.*(..))"/> <aop:pointcut id="repositoryPointcut" expression="execution(* br.com.ar..repository.*Repository.*(..))"/> <aop:advisor advice-ref="serviceTransactionManagementAdvice" pointcut-ref="servicePointcut"/> <aop:advisor advice-ref="repositoryTransactionManagementAdvice" pointcut-ref="repositoryPointcut"/> </aop:config> <bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor"/> </beans>

<强>测试

要测试带注释的@Controller方法，请参阅here如何

除了网络图层。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

<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <context-param> <param-name>contextConfigLocation</param-name> <param-value> classpath:ar-persistence.xml classpath:ar-service.xml </param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>ar</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>ar</servlet-name> <url-pattern>*.html</url-pattern> </servlet-mapping> <session-config> <session-timeout>30</session-timeout> </session-config> <resource-ref> <description>datasource</description> <res-ref-name>jdbc/dataSource</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> </web-app>

我希望它有用。更新架构到Spring 3.0。请参阅Spring参考文档。 mvc schema，据我所知，只在Spring 3.0中得到支持。牢记这一点
