java.util.NoSuchElementException创建春数据仓库JPA豆

Question

我的依赖关系是：

springVersion = '3.2.4.RELEASE'

compile "org.springframework:spring-***:$springVersion" 
*** = all of them are included just in case! 
compile "org.springframework.data:spring-data-jpa:1.4.1.RELEASE" 
compile "org.hibernate.javax.persistence:hibernate-jpa-2.0-api:1.0.1.Final" 
runtime "org.hibernate:hibernate-entitymanager:4.2.6.Final" 
testCompile "org.springframework:spring-test:$springVersion" 
runtime "com.h2database:h2:1.3.173" 

我有以下方面的文件：

<tx:annotation-driven /> 

<jpa:repositories base-package="au.com.data3.samples.user.priv" /> 

<jdbc:embedded-database id="dataSource" type="H2"> 
</jdbc:embedded-database> 

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> 
    <property name="dataSource" ref="dataSource" /> 
    <property name="packagesToScan" value="au.com.data3.samples.user.model" /> 
    <property name="jpaVendorAdapter"> 
     <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> 
      <property name="showSql" value="false" /> 
      <property name="generateDdl" value="true" /> 
      <property name="database" value="H2" /> 
     </bean> 
    </property> 
    <property name="jpaProperties"> 
     <props> 
      <!--<prop key="hibernate.max_fetch_depth"></prop>--> 
      <prop key="hibernate.hbm2ddl.auto">create-drop</prop> 
      <prop key="hibernate.dialect">org.hibernate.dialect.H2Dialect</prop> 
     </props> 
    </property> 
</bean> 

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> 
    <property name="entityManagerFactory" ref="entityManagerFactory" /> 
</bean> 

我在.... user.priv包中有我的存储库类：

public interface D3UserRepository extends JpaRepository<D3User, Long> { 

D3User findByUsername(String username); 
    List<D3User> findByFirstName(String firstName); 
    List<D3User> findByLastName(String lastName); 
    List<D3User> findByFirstNameAndLastName(String lastName); 
} 

我已经在它下面这将导致该错误的春天/ JUnit测试：

@Autowired 
private D3UserService mD3UserService; 

堆栈跟踪是：

我在做什么错？我已经尝试了类似帖子的许多不同的东西，但没有任何工作。

请帮忙。

如果它是有一定的帮助还是：你错过了第二parmeter在

List<D3User> findByFirstNameAndLastName(String lastName); 

它必须是

List<D3User> findByFirstNameAndLastName(String firstName, String lastName);
