我是 Spring 和 Spring Data 的新手，我创建了简单的应用程序。但是，我的应用程序的 Controller 始终无法自动连接存储库，即使我有一个

CustomerController.java

package controllers;

import persistence.domains.Customer;
import repositories.CustomerService;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping(value = "/customers")
@Service
public class CustomerController {


    private CustomerService customerRepository;


    @Autowired
    public CustomerController(CustomerService customerRepository) {
        this.customerRepository = customerRepository;
    }

    @RequestMapping(method = RequestMethod.GET)
    public List<Customer> getAllCustomers() {
        return customerRepository.findAll();
    }


}

CustomerRepository.java

package persistence.repositories;

import persistence.domains.Customer;

import java.util.List;

import org.springframework.data.repository.CrudRepository;

public interface CustomerRepository extends CrudRepository<Customer,Long> {

    public Customer save(Customer customer);
    public Customer findOneByName(String name);
    public List<Customer> findAll();
}

CustomerService.java

package persistence.repositories;

import persistence.domains.Customer;

import java.util.List;

public interface CustomerService {
    /**
     * Return all customers
     * @return A list of all customers
     */
    public List<Customer> findAll();
}

RepositoryCustomerService.java

package persistence.repositories;

import persistence.domains.Customer;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;

@Component
public class RepositoryCustomerService implements CustomerService {
    @Resource
    private CustomerRepository repo;

    @Transactional
    public List<Customer> findAll() {
        return repo.findAll();

    }

}

持久化配置.java

package configurations;

import javax.persistence.EntityManagerFactory;
import javax.sql.DataSource;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Profile;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.jdbc.datasource.embedded.EmbeddedDatabaseBuilder;
import org.springframework.jdbc.datasource.embedded.EmbeddedDatabaseType;
import org.springframework.orm.jpa.JpaTransactionManager;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter;
import org.springframework.transaction.PlatformTransactionManager;

@Configuration
@EnableJpaRepositories
public class PersistenceConfig {

    @Bean
    @Profile("embedded")
    public DataSource dataSourceEmbedded() {
        System.out.println("CREATE DATA SOURCE BEAN");
        return new EmbeddedDatabaseBuilder().setType(EmbeddedDatabaseType.HSQL)
                .addScript("classpath:sql/schema.sql")
                .addScript("classpath:sql/test-data.sql").build();
    }

    @Bean
    public DriverManagerDataSource dataSource() {
        DriverManagerDataSource ds = new DriverManagerDataSource();
        ds.setDriverClassName("com.mysql.jdbc.Driver");
        ds.setUrl("jdbc:mysql://127.0.0.1:3306/database-name");
        ds.setUsername("root");
        ds.setPassword("");
        return ds;
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        vendorAdapter
                .setDatabase(org.springframework.orm.jpa.vendor.Database.MYSQL);
        vendorAdapter.setGenerateDdl(true);
        LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
        factory.setJpaVendorAdapter(vendorAdapter);
        factory.setPackagesToScan(getClass().getPackage().getName());
        factory.setDataSource(dataSource());
        return factory;
    }

    @Bean
    public PlatformTransactionManager transactionManager() {
        JpaTransactionManager txManager = new JpaTransactionManager();
        txManager.setEntityManagerFactory((EntityManagerFactory) entityManagerFactory());
        return txManager;
    }
}

这是错误堆栈

最佳答案

告诉Spring你的存储库在哪里，以及你的实体在哪里:

@Configuration
@EnableJpaRepositories(basePackages="persistence.repositories")
@EntityScan(basePackages="...")
public class PersistenceConfig {
...

理想情况下，您应该使用 basePackageClasses 与 basePackages 来确保类型安全。

 @EnableJpaRepositories(basePackageClasses={RepositoryPackageMarker.class})
