BeanCreationException error happend on spring when I try to seperate the springMVC context with the root context bean scan -

i define 2 spring context files application, springmvc-config.xml springmvc , han-config.xml root application context. want utilize springmvc-config.xml scan @controller beans , han-config.xml scan @component, @repository, , @service beans

my problem if utilize <context:component-scan base-package="com.leo.han" / > in springmvc-config.xml application run , no errors during deployment. if want utilize <context:component-scan base-package="com.leo.han.controllers" use-default-filters="false"> <context:include-filter type="annotation" expression="org.springframework.stereotype.controller" /> </context:component-scan> in springmvc-config.xml scan controllers , utilize <context:component-scan base-package="com.leo.han" use-default-filters="false"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.controller" /> </context:component-scan> in han-config.xml scan @component, @repository, , @service beans recommended approach in spring forum. terrible errors org.springframework.beans.factory.beancreationexception: error creating bean name 'logincontroller': injection of autowired dependencies failed; nested exception org.springframework.beans.factory.beancreationexception: not autowire field: private com.leo.han.services.userservice com.leo.han.controllers.logincontroller.userservice; nested exception org.springframework.beans.factory.nosuchbeandefinitionexception: no qualifying bean of type [com.leo.han.services.userservice] found dependency: expected @ to the lowest degree 1 bean qualifies autowire candidate dependency. dependency annotations: {@org.springframework.beans.factory.annotation.autowired(required=true)} seems userservice bean never created reason can help me on bundle construction is: com.leo.han.controllers (all controllers annotated @controller) com.leo.han.services (all service annotated @service) com.leo.han.dao (all das annotated @repository) here sample code @controller public class logincontroller { @autowired private userservice userservice;

i using similar configuration base of operations bundle same "a.b" in both cases , 1 contains exclusion controllers ( root context) , other consists of inclusion ( mvc context) , works fine. can seek that.

now you'd love spring - if want programmatically determine candidate beans in classpath base of operations package, can write simple test programme below list candidate components.

public class testcomponentscanner { public static void main(string[] args) { classpathscanningcandidatecomponentprovider provider = new classpathscanningcandidatecomponentprovider(true); string basepackage = "com/leo"; provider.addexcludefilter(new annotationtypefilter(controller.class, true)); set<beandefinition> filteredcomponents = provider.findcandidatecomponents(basepackage); system.out.println("no of components :"+filteredcomponents.size()); (beandefinition component : filteredcomponents) { system.out.println("component:"+ component.getbeanclassname()); } provider.resetfilters(true); provider.addincludefilter(new annotationtypefilter(controller.class, true)); filteredcomponents = provider.findcandidatecomponents(basepackage); system.out.println("no of components :"+filteredcomponents.size()); (beandefinition component : filteredcomponents) { system.out.println("component:"+ component.getbeanclassname()); } }
