JPAAdminUserDao class have method findUserByEmail

JPAAdminUserDao类有方法findUserByEmail

   @Transactional
 public class JPAAdminUserDao extends JPAGenericDao<AdminUser, Long> 
   implements AdminUserDao {
@Autowired
private EntityManager entityManagerFactoryBean;
/**
 * 
 * @param email receiving
 * @return AdminUser object
 */
public final AdminUser findUserByEmail(final String email) {
    List<AdminUser> users = new ArrayList<AdminUser>();
    users =       (List<AdminUser>)entityManagerFactoryBean.getEntityManagerFactory().createEntityManager()
            .createQuery("from " + AdminUser.class.getName() 
                    + " as user where user.email=:email")
            .setParameter("email", email).getResultList();
    if (users.size() > 0) {
        return users.get(0);
    } else {
        return null;
    }
}
}

UserDetailsServiceImplementation

public class UserDetailsServiceImplementation implements UserDetailsService   {

/**
 * Using JPAAdminUserDao object.
 */
@Autowired
private JPAAdminUserDao jpaUserDao;

 @Override
public final UserDetails loadUserByUsername(final String username) 
        throws UsernameNotFoundException {

    HashSet<String> set = new HashSet<String>();
    AdminUser user = (AdminUser) jpaUserDao.findUserByEmail(username);
    if (user instanceof AdminUser) {
        set.add(new String("ROLE_USER"));
        set.add(new String("ROLE_ADMIN"));
        set.add(new String("ROLE_REDADMIN"));
    } else {
        set.add(new String("ROLE_USER"));
    }
    List<GrantedAuthority> authorities = buildUserAuthority(set);
    return buildUserForAuthentication(user, authorities);

}

/**
 * 
 * @param user Receiving user object
 * @param authorities Receiving list of user authorities 
 * @return returning user object 
 */
private User buildUserForAuthentication(final AdminUser user, 
        final List<GrantedAuthority> authorities) {
    return new User(user.getEmail(), user.getPassword(), true, 
            true, true, true, authorities);
}

/**
 * 
 * @param userRoles receiving
 * @return Returning list of authorities
 */
private List<GrantedAuthority> buildUserAuthority(final 
        Set<String> userRoles) {

    Set<GrantedAuthority> setAuths = new HashSet<GrantedAuthority>();
    // Build user's authorities
    for (String userRole : userRoles) {
        setAuths.add(new SimpleGrantedAuthority(userRole));
    }
    List<GrantedAuthority> result = new 
            ArrayList<GrantedAuthority>(setAuths);

    return result;
}

public final JPAAdminUserDao getJpaUserDao() {
    return jpaUserDao;
}

public final void setAdminUserDao(final JPAAdminUserDao newJpaUserDao) {
    this.jpaUserDao = newJpaUserDao;
}
}

If i comment next line

如果我评论下一行

<beans:property name="entityManagerFactoryBean"     ref="entityManagerFactoryBean"/>

in spring-security I will have java.lang.NullPointerException in JPAAdminUserDao class in method findUserByEmail

在spring-security中,我将在方法findUserByEmail中的JPAAdminUserDao类中使用java.lang.NullPointerException

You seem to have problems while you are loading your spring xml beans configuration files. Your persistence-context.xml is probably never loaded.

在加载spring xml beans配置文件时,您似乎遇到了问题。您的persistence-context.xml可能永远不会被加载。

Are you sure that this line is importing the persistence-context.xml file (Remove it if it is no longer necessary, it may load some context twice) :

您确定此行正在导入persistence-context.xml文件(如果不再需要,则删除它,它可能会加载一些上下文两次):

<import resource="classpath*:**/spring/*context.xml" />

Try to add the persistence-context.xml in the context-param in your web.xml

尝试在web.xml中的context-param中添加persistence-context.xml

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/spring-security.xml
        **/path/to/persistence-context.xml
    </param-value>
</context-param>

To ensure that your servlet-context.xml file is correctly loaded, add an init param to your DispatcherServlet declaration in your web.xml :

要确保正确加载servlet-context.xml文件,请在web.xml中的DispatcherServlet声明中添加init参数:

<servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/path/to/servlet-context.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
