Question

我刚遇到配置问题。调用我的服务时出现以下错误（未定义名为'***'的bean）。我发现的所有其他帖子都没有帮助我。任何帮助都会非常感激。

调度程序servlet：

<import resource="classpath:spring/mvc-view-config.xml" />
<import resource="classpath:spring/database-config.xml" />
<import resource="classpath:spring/hibernate-config.xml" />

<context:annotation-config />

<mvc:resources mapping="/resources/**" location="/resources/" />
<mvc:annotation-driven />
<context:component-scan base-package="de.christian.api*" />

冬眠-配置：

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"></property>
    <property name="annotatedClasses">
        <list>
            <value>de.christian.api.model.User</value>
            <value>de.christian.api.model.News</value>
            <value>de.christian.api.model.Tag</value>
            <value>de.christian.api.model.Project</value>
            <value>de.christian.api.model.Article</value>
            <value>de.christian.api.model.News</value>
            <value>de.christian.api.model.GuestbookEntry</value>
            <value>de.christian.api.model.News</value>
            <value>de.christian.api.model.Tag</value>
            <value>de.christian.api.model.Project</value>
            <value>de.christian.api.model.Article</value>
            <value>de.christian.api.model.News</value>
            <value>de.christian.api.model.GuestbookEntry</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
            <prop key="hibernate.show_sql">true</prop>
        </props>
    </property>
</bean>

<bean id="transactionManager"
    class="org.springframework.orm.hibernate4.HibernateTransactionManager"
    p:sessionFactory-ref="sessionFactory">
</bean>

应用程序上下文：

<context:component-scan base-package="de.christian.api.controller" />
<mvc:resources mapping="/resources/**" location="/resources/" />
<mvc:annotation-driven />

<bean
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix">
        <value>/</value>
    </property>
    <property name="suffix">
        <value>.html</value>
    </property>
</bean>

服务：

@Service("guestbookEntryService")
public class GuestbookEntryServiceImpl implements IGuestbookEntryService {

控制器调用：

ConfigurableApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
gservice =          (IGuestbookEntryService)context.getBean("guestbookEntryService");

我希望有人对我有所暗示。

Answer 1

因为您正在谈论base-package春天应该知道它应该在不添加*的情况下查看更深层的包。请尝试：

<context:component-scan base-package="de.christian.api" />

有关详细信息，请查看this。

Answer 2

需要注意几件事。您的控制器将作为application-context.xml的一部分进行扫描，并且您的服务/ daos将作为dispatcher-servlet.xml的一部分进行扫描。它们是两种不同的背景。尝试从控制器代码中的dispatcher-servlet.xml获取它。

没有名为＆＃39; ***＆＃39;是定义的（Spring，Hibernate）
