NoSuchDefinitionException：沒有匹配的類型爲

Question

的bean

所以我搜索了一下，但沒有找到答案，或者我找到的東西可以幫助我。

控制器類：

@Controller 
public class SearchController { 
    protected Logger logger = LoggerFactory.getLogger(this.getClass()); 
    private static final String VIEW_SEARCH = "customerSearch"; 

    @Autowired 
    private CustomerSearchService customerSearchService; 

//snip 

服務實現（該接口沒有註釋）：

@Service("customerSearchService") 
public class CustomerSearchServiceImpl implements CustomerSearchService{ 

    @Autowired 
    private HistoryTxService historyTxService; 

    @Autowired 
    private CustomerTxService customerTxService; 

//snip 

從我的理解：

@Service 
@Qualifier("customerSearchService") 

和

@Service("customerSearchService") 

表現相同，它們也產生相同的錯誤。

這是我的數據源-context.xml中：

<?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.xsd 
     http://www.springframework.org/schema/context 
     http://www.springframework.org/schema/context/spring-context-3.1.xsd"> 

    <context:annotation-config/> 
    <context:component-scan base-package="com.nimchip.project.data.dao.impl"/> 
    <context:component-scan base-package="com.nimchip.project.data.tx.impl"/> 
    <context:component-scan base-package="com.nimchip.project.data.service.impl"/> 

    <bean id="initScript" class="org.springframework.core.io.ClassPathResource"> 
     <constructor-arg index="0" value="sql/schema.sql"/> 
    </bean> 

    <bean name="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
     <property name="driverClassName" value="net.sourceforge.jtds.jdbc.Driver"/> 
     <property name="url" value="jdbc:jtds:sqlserver://test/project2;instance=DEV"/> 
     <property name="username" value="username"/> 
     <property name="password" value="password"/> 
    </bean> 

    <bean name="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate"> 
     <constructor-arg ref="dataSource"/> 
    </bean> 

    <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> 
     <property name="dataSource" ref="dataSource"/> 
    </bean> 

</beans> 

任何線索？當然，我的控制器在project-webapp，我的tx/services/daos在project-dataacess，當然這些都包含在全局pom和webapp pom中。

我應該補充一點，我已經從dataaccess模塊​​中單元測試過服務，它們工作正常。

Answer 1

糟糕，似乎我的web.xml缺少一些監聽器。我的web.xml是：

<web-app id="WebApp_ID" 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"> 

    <display-name>New Project</display-name> 


    <context-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value> 
      /WEB-INF/datasource-context.xml 
     </param-value> 
    </context-param>  

    <!-- Spring MVC --> 
    <servlet> 
     <servlet-name>dispatcher</servlet-name> 
     <servlet-class> 
      org.springframework.web.servlet.DispatcherServlet 
     </servlet-class> 
     <load-on-startup>1</load-on-startup> 
    </servlet> 
    <servlet-mapping> 
     <servlet-name>dispatcher</servlet-name> 
     <url-pattern>/</url-pattern> 
    </servlet-mapping> 

    <session-config> 
     <session-timeout>30</session-timeout> 
    </session-config> 

    <welcome-file-list> 
     <welcome-file>index.jsp</welcome-file> 
    </welcome-file-list> 

</web-app> 

於是我說：

<listener> 
     <listener-class> 
      org.springframework.security.web.session.HttpSessionEventPublisher 
     </listener-class> 
    </listener> 

    <listener> 
     <listener-class> 
      org.springframework.web.context.ContextLoaderListener 
     </listener-class> 
    </listener> 

    <listener> 
     <listener-class> 
      ch.qos.logback.classic.selector.servlet.ContextDetachingSCL 
     </listener-class> 
    </listener> 

這固定它。所以，如果你有這個問題，確保你有這些設置！
