java.util.NoSuchElementException tạo mùa xuân dữ liệu JPA đậu kho

Question

phụ thuộc của tôi là:

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" 

Tôi có tập tin bối cảnh sau đây:

<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> 

Tôi có lớp Kho lưu trữ trong gói .... user.priv:

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); 
} 

Tôi có một bài kiểm tra/JUnit mùa xuân đã điều sau đây trong nó mà gây ra lỗi:

@Autowired 
private D3UserService mD3UserService; 

Các stacktrace là:

Tôi đang làm gì sai? Tôi đã thử nhiều thứ khác nhau từ các bài viết tương tự nhưng không có gì có hiệu quả.

Vui lòng trợ giúp.

Answer 1

Nếu nó vẫn là của một số giúp đỡ: Bạn bỏ lỡ parmeter thứ hai trong

List<D3User> findByFirstNameAndLastName(String lastName); 

Nó phải được

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