Spring throws exception for undefined bean

I follow this guide to use Spring Security. I would like to use Hibernate for database queries. I configured the code, but the following exception is thrown.

I defined bean in spring-security.xml and my-servlet.xml , but still no result.

 Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'myMemberDetailsService' is defined at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition(DefaultListableBeanFactory.java:570) at org.springframework.beans.factory.support.AbstractBeanFactory.getMergedLocalBeanDefinition(AbstractBeanFactory.java:1114) at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:279) at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:194) at org.springframework.beans.factory.support.BeanDefinitionValueResolver.resolveReference(BeanDefinitionValueResolver.java:320) ... 93 more

MemberRepository

 public class MemberRepositoryImpl implements MemberRepository { SessionFactory sessionFactory; @SuppressWarnings("unchecked") @Override public Member findByUserName(String username) { List<Member> members = new ArrayList<Member>(); members = sessionFactory.getCurrentSession() .createQuery("from Member where username=?") .setParameter(0, username).list(); if (members.size() > 0) { return members.get(0); } else { return null; } } }

MyMemberDetailsService

 public class MyMemberDetailsService implements UserDetailsService { private MemberRepository memberRep; @Override public UserDetails loadUserByUsername(final String username) throws UsernameNotFoundException { Member member = memberRep.findByUserName(username); HashSet<String> roles = new HashSet<String>(); roles.add("ROLE_MEMBER"); List<GrantedAuthority> authorities = buildUserAuthority(roles); return buildUserForAuthentication(member, authorities); } // Converts com.mkyong.users.model.User user to // org.springframework.security.core.userdetails.User private User buildUserForAuthentication(Member member, List<GrantedAuthority> authorities) { return new User(member.getUsername(), member.getPassword(), member.isEnabled(), true, true, true, authorities); } private List<GrantedAuthority> buildUserAuthority(Set<String> userRoles) { Set<GrantedAuthority> setAuths = new HashSet<GrantedAuthority>(); // Build user authorities for (String userRole : userRoles) { setAuths.add(new SimpleGrantedAuthority(userRole)); } List<GrantedAuthority> Result = new ArrayList<GrantedAuthority>( setAuths); return Result; } }

I just read the tutorial and I saw that it did not mention anything about the web.xml configuration, so I downloaded it to see how it was configured.

You said that you tried to define myMemberDetailsService in both places, my-servlet and spring-security , but that didn't work.

Well, I think this is a configuration problem, so please try changing your web.xml as follows (I used the names that you used in your question, but please check if there is something wrong):

 <servlet> <servlet-name>my-servlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/my-servlet.xml, /WEB-INF/spring-security.xml </param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet>

And remove your global <context-param> for the contextConfigLocation parameter, if any.

If this does not work, I will recommend that you use a similar configuration, such as a tutorial, that is, leave the minimum MVC configuration in my-servlet.xml and configure the rest of the beans in a separate context.

Hope this helps!

Enabling UserDetailsService in security xml resolve the issue.

In your spring-security.xml include an implementation definition for MyMemberDetailsService.

 <beans:bean class="your.package.MyMemberDetailsService" id="myMemberDetailsService" />

I see that you include login-service.xml in your spring-security.xml . Therefore, defining a bean user service in login-service.xml will also solve the problem.

According to the tutorial, web.xml should contain a link to your spring config xml.

web.xml will look like

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

The mvc-dispatcher-servlet xml file should contain an import of all the other xmls.

mvc-dispatcher-servlet xml will look like

  <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" ..."> <import resource="my-servlet.xml" /> <import resource="spring-security.xml" /> ... </beans>
