Spring mvc在controller中注入service时报空

[小虫hh]

今天配置spring mvc时一直报空，找不到问题在哪里。希望各位帮帮忙。
tomcat能正常启动，没有报错，但是在调用controller时注入的service对象为null
web.xml配置

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/applicationContext.xml</param-value>
</context-param>
<servlet>
<servlet-name>rest</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>rest</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

applicationContext.xml已有：
<context:component-scan base-package="com"/>
<mvc:default-servlet-handler/>
<mvc:annotation-driven />

controller代码

@Controller
@RequestMapping(value = "/sync")
public class servicecontroller extends BaseController{

@javax.annotation.Resource(name = "syncClientService")
private ISyncClientService syncClientService;

@RequestMapping(value = "/start")
@ResponseBody
private String syncStart(HttpServletRequest request) throws Exception{
CreLogger.info("**********Strat invoke synchusers...");
JSONObject jsonPara = getJsonPara(request);
String sychUrl = jsonPara.getString("syncurl");

SynchroniseuserResponse response = syncClientService.syncUserStart(sychUrl);
if (response != null) {
SynchroniseuserResponseType responseType = response.getSynchroniseuserResponse();
if (responseType.getResultCode() == 0) {
CreLogger.info("**********同步成功...");
return "同步成功！";
}else {
CreLogger.info("**********同步失败...");
return "同步失败！";
}
}else {
CreLogger.info("**********同步失败...");
return "同步失败！";
}

}

}

service代码：
@Service("syncClientService")
public class syncClientService implements ISyncClientService{
private static com.dayangit.cre.util.CreLogger CreLogger = com.dayangit.cre.util.CreLogger.getLogger(servicecontroller.class);

@javax.annotation.Resource(name = "AuthorizationManager")
private AuthorizationManager authorizationManager;

@SuppressWarnings("null")
public SynchroniseuserResponse syncUserStart(String url) {
try {
SynchroniseUsersServiceStub stub = new SynchroniseUsersServiceStub(url);
SynchroniseuserRequest request = new SynchroniseuserRequest();
SynchroniseuserRequestType requestType = new SynchroniseuserRequestType();
//设置全局同步
CreLogger.info("**********设置全局同步**********");
requestType.setSyncAll(true);
ModifiedModuleInfoType moduleInfo = new ModifiedModuleInfoType();

requestType.setModifiedModuleInfo(moduleInfo);
request.setSynchroniseuserRequest(requestType);
SynchroniseuserResponse response = stub.synchroniseUsers(request);
return response;
} catch (Exception e) {
CreLogger.error("exception",e);
}
return null;

}
里面的具体逻辑就省了，很长

<context:component-scan base-package="com"/> 这个包名写精确一点

[小虫hh]

谢谢，麻烦再详细说一下吧，这个包应该写到什么地方呢？
包结构是这样的，我改成com.dayang还是不行

[jxxiaotao]

写成com.dayang.*就行

谢了~试过，不行呢~~

版主再帮忙看一下吧

spring的配置文件呢？

<context:component-scan base-package="com.dayang.*"/> <mvc:default-servlet-handler/> <mvc:annotation-driven /> 还需要别的吗？

1：<context:component-scan base-package="com.*"/> 2：<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" /> <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />

试了，，还是不行

<context:component-scan base-package="com.ecp888.passport">
		<context:include-filter type="regex"
			expression=".dao..*" />
		<context:include-filter type="regex"
			expression=".service..*" />
	</context:component-scan>

	<context:annotation-config />

[chenjazz]

你就不能格式化代码在发出来啊

[Yaphets_VJ]

<context:component-scan base-package="com" > <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan>

看了所有评论及回复 我也不知道了
