Question

我使用Spring Initializr生成了一个Spring Boot Web应用程序，使用嵌入式Tomcat和包作为可执行的JAR文件。

这是主要的应用程序：

package com.tdk;


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import com.tdk.repository.JdbcRemoteUnitRepository;


@SpringBootApplication
public class TdkDeviceManagerApp implements CommandLineRunner {


    @Autowired
    private JdbcRemoteUnitRepository jdbcRemoteUnitRepository;

    public static void main(String[] args) {
        SpringApplication app = new SpringApplication(TdkDeviceManagerApp.class);
        app.run(args);
    }

    @Override
    public void run(String... arg0) throws Exception {

        jdbcRemoteUnitRepository.getUnitsWithoutFirmwareInfo();
    }
}

这1个存储库类：

package com.tdk.repository;

    /**
     * @author  tdk ©
     * @version 1.0
     * @since  15 sept. 2017
     */
    @Transactional
    @Service
    public class JdbcRemoteUnitRepository {
    ..
    }



    @ContextConfiguration(classes={ProductionPersistenceConfig.class})
    @RunWith(SpringRunner.class)
    public class JdbcRemoteUnitRepositoryTests {

        @Autowired
        private JdbcRemoteUnitRepository repository;

        @Test   
        public void testGetAllGuardians() throws DataAccessException, SQLException {        
            assertEquals(2, 2);
        }

    }

这是测试类中的一个：

@ContextConfiguration(classes={ProductionPersistenceConfig.class})
@RunWith(SpringRunner.class)
public class JdbcRemoteUnitRepositoryTests {

    @Autowired
    private JdbcRemoteUnitRepository repository;

    @Test   
    public void testGetAllGuardians() throws DataAccessException, SQLException {        
        assertEquals(2, 2);
    }

}

当我启动应用程序时。从Eclipse一切都很好，没有问题。但是当我在Eclipse中运行测试时出现了这个错误：

尝试使用注释@SpringBootTest。

此外，您还可以找到有用的注释@Profile("test")，利用它可以为测试环境设置另一个数据库。

SpringBoot注入：使用app可以，但不能使用测试
