Question

我根据弹簧启动和弹簧启动数据创建了一个应用程序，所以我想使用

内存中的HSQLDB

这是我的应用程序类：

package boot;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication()
public class Application {

    public static void main(String[] args) {

        SpringApplication.run(Config.class);

    }

}

这是Config类：

@Configuration
@EnableAutoConfiguration
@EnableJpaRepositories
@ComponentScan(basePackages = {"controller", "dao", "service"})
@EnableTransactionManagement
class Config {


    @Bean(name = "dataSource")
    public DataSource dataSource() {
        EmbeddedDatabaseBuilder builder = new EmbeddedDatabaseBuilder();
        return builder.setType(EmbeddedDatabaseType.HSQL).build();
    }

    @Bean(name = "entityManager")
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        vendorAdapter.setDatabase(Database.HSQL);
        vendorAdapter.setGenerateDdl(true);

        LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
        factory.setJpaVendorAdapter(vendorAdapter);
        factory.setPackagesToScan(getClass().getPackage().getName());
        factory.setDataSource(dataSource());

        return factory;
    }

    @Bean
    public PlatformTransactionManager transactionManager() {
        return new JpaTransactionManager();
    }

}

正如你在这三个包中“kenow”“控制器”，“dao”，“服务”那样一些@Autowired

当我运行应用程序时，我收到了这个错误：

Error creating bean with name 'taskController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private service.TaskManager controller.TaskController.taskManager; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'taskManagerImpl' defined in file [D:\JavaSe\restAng\target\classes\service\impl\TaskManagerImpl.class]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/aspectj/util/PartialOrder$PartialComparable

    at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:197) ~[spring-beans-4.2.6.RELEASE.jar:4.2.6.RELEASE]

这是我的TaskController

@RestController
public class TaskController {

    @Autowired
    private TaskManager taskManager;


    @RequestMapping(value = "/tasks", method = RequestMethod.GET, headers = "Accept=application/json")
    public List<Task> getAllTasks() {
        return taskManager.getAll();
    }
}

它出了什么问题？

Answer 1

您缺少aspectjweaver。您需要将其添加到依赖项中。

<dependency>
   <groupId>org.aspectj</groupId>
   <artifactId>aspectjweaver</artifactId>
   <version>1.8.9</version>
</dependency>
