Question

尝试在Junit中运行测试时遇到BeanCreation异常。看来春天是试图自动装备该领域时遇到问题。

测试类是： -

    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration(locations = {"classpath*:servlet-context.xml"})
    @ComponentScan("com.org.devcenter.processtutorials")
    public class LdapDirectoryContextSetupTest {
    @Autowired
    LdapDirectoryContext ldapSetup;

    private final static String securityPrincipal = "xxx"; 
    private final static String initialContextfactory = "xxx";
    private final static String providerUrl = "xxx";
    private final static String securityAuthentication = "xxx";

    @Test
    public void testEnvironmentProperties(){

        assertEquals(securityPrincipal, ldapSetup.createLdapEnvironmentProperties().get(Context.SECURITY_PRINCIPAL));
        assertEquals(providerUrl, ldapSetup.createLdapEnvironmentProperties().get(Context.PROVIDER_URL));
        assertEquals(securityAuthentication, ldapSetup.createLdapEnvironmentProperties().get(Context.SECURITY_AUTHENTICATION));
        assertEquals(initialContextfactory, ldapSetup.createLdapEnvironmentProperties().get(Context.INITIAL_CONTEXT_FACTORY));       
    }
}

我正在尝试测试的课程如下： -

    @Component
    public class LdapDirectoryContext {

    @Value("${security_Principal}")
    private String securityPrincipal;
    @Value("${intital_context_Factory}")    
    private String initialContextfactory;

    @Value("${provider_Url}")
    private String providerUrl;
    @Value("${security_Authentication}")
    private String securityAuthentication;

    /**
     * This method sets up and returns the ldapConnectionProperties hashtable. 
     * @return ldapConnectionProperties Hashtable.
     */
    public Hashtable<String,String> createLdapEnvironmentProperties(){

        Hashtable<String,String> ldapEnvironmentProperties = new  Hashtable<String,String>();
        ldapEnvironmentProperties.put(Context.PROVIDER_URL, providerUrl);
        ldapEnvironmentProperties.put(Context.SECURITY_PRINCIPAL, securityPrincipal);
        ldapEnvironmentProperties.put(Context.SECURITY_AUTHENTICATION, securityAuthentication);
        ldapEnvironmentProperties.put(Context.INITIAL_CONTEXT_FACTORY, initialContextfactory);  

        return ldapEnvironmentProperties;
    }

    /**
     * This method creates a DirContext(directory context) object based on the ldapConnectionProperties Hashtable passed.
     * @param ldapConnectionProperties Hashtable passed.
     * @return DirContext object.
     * @throws NamingException if the context object could not be created due to invalid Ldap properties supplied
     * or when encountering issues interacting with the Ldap Server. 
     */
    public DirContext getDirContext(Hashtable<String, String> ldapConnectionProperties ) throws NamingException{
        return new InitialDirContext(ldapConnectionProperties);
    }
}

我的servlet上下文如下所示： -
