春天JPA BeanCreationException：無法解析參考豆「的entityManagerFactory」，同時設置構造函數的參數;

Question

我是新來春數據JPA。我想配置與Spring數據JPA我的maven webapp項目2天，現在我卡住了，因爲我得到實體廠長惱人的錯誤我。我已經驗證我的配置，但仍然無法理解爲什麼我的LogicImpl無法自動裝配倉庫，造成內部bean例外。我認爲有一些缺失，但我無法弄清楚。 我想使用Spring的事務templete在我的代碼，以及它工作正常，如果不使用我的資料庫界面在我logicImpl 我附上我的配置和代碼文件 ApplicationConfiguration.java

@Configuration 
@EnableJpaRepositories("com.itob.persistence.repository") 
@EnableTransactionManagement 
public class ApplicationConfiguration { 
@Autowired 
private DataSource dataSource; 
@Bean 
public JdbcTemplate jdbcTemplate(){return new JdbcTemplate(dataSource);} 
@Bean 
public DataSource dataSource(){ 
    BasicDataSource dataSource =new BasicDataSource(); 
    dataSource.setDriverClassName("oracle.jdbc.driver.OracleDriver"); 
    dataSource.setUrl("jdbc:oracle:thin:@localhost:1521:xe"); 
    dataSource.setUsername("hr");dataSource.setPassword("system");return dataSource; 
} 
@Bean 
public PlatformTransactionManager transactionManager() { 
    EntityManagerFactory factory = entityManagerFactory(); 
    return new JpaTransactionManager(factory); 
} 
@Bean 
public EntityManagerFactory entityManagerFactory() { 
    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter(); 
    vendorAdapter.setGenerateDdl(Boolean.TRUE); 
    vendorAdapter.setShowSql(Boolean.TRUE); 
    LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean(); 
    factory.setJpaVendorAdapter(vendorAdapter); 
    factory.setPackagesToScan("com.itob.persistence.model"); 
    factory.setDataSource(dataSource()); 
    factory.afterPropertiesSet(); 
    factory.setLoadTimeWeaver(new InstrumentationLoadTimeWeaver()); 
    return factory.getObject(); 
} 

DepartmentLogicImpl.java

import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.stereotype.Component; 
import org.springframework.transaction.annotation.Transactional; 

@Component 
public final class DepartmentLogicImpl implements IDepartmentLogic { 

@Autowired 
private DepartmentDao departmentDaoHbnImpl; 

@Autowired 
private IDepartmentConverter departmentConverterImpl; 

@Autowired 
private UserRepository userRepository; 

public DepartmentResponseBean getData() { 


    Department department = departmentConverterImpl.convertRequest("AMR"); 
    int insertedRows = departmentDaoHbnImpl.saveDepartment(department); 
    DepartmentResponseBean businessResponse = departmentConverterImpl.convertInsertedRecord(insertedRows); 
    return businessResponse; 
} 

@Transactional 
@Override 
public long totalUsers() { 
    return userRepository.count(); 
} 
}

Answer 1

你需要的是增加 @EnableJpaRepositories(basePackages="com.zxg.springdata",entityManagerFactoryRef="factoryBean")

你必須映射您的entityManagerFactory
