java - NoSuchDefinitionException : No matching bean of type

Question

所以我进行了搜索和谷歌搜索，但没有任何答案或我发现可以帮助我。

Nov 27, 2012 11:24:32 AM org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet dispatcher threw exception

Controller 类:

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

    @Autowired
    private CustomerSearchService customerSearchService;

//snip

服务实现(接口(interface)没有注释):

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

    @Autowired
    private HistoryTxService historyTxService;

    @Autowired
    private CustomerTxService customerTxService;

//snip

据我了解:

 @Service
 @Qualifier("customerSearchService")

和

 @Service("customerSearchService")

执行相同的操作，也会产生相同的错误。

这是我的 datasource-context.xml:

<?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>

有什么线索吗？当然，我的 Controller 位于 project-webapp 中，我的 tx/services/daos 位于 project-dataacess 中，这些当然包含在全局 pom 和 webapp 中pom。

我应该补充一点，我已经对数据访问模块内的服务进行了单元测试，并且它们运行良好。

哎呀，我的 web.xml 似乎缺少一些监听器。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>

所以我添加了:

    <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>

这解决了它。因此，如果您遇到此问题，请确保您已设置这些!
