UnsatisfiedDependencyException：创建名称为“exerciseController”的 bean 时出错

【问题标题】：UnsatisfiedDependencyException: Error creating bean with name 'exerciseController'UnsatisfiedDependencyException：创建名称为“exerciseController”的 bean 时出错
【发布时间】：2018-01-31 10:33:52
【问题描述】：

所以我正在使用 Spring Boot 创建一个小型 Web 应用程序，但是当我运行它时，我收到此错误“创建名称为 exerciseController 的 bean 时出错。我已经将我的实体和控制器分开在单独的包中。我还为 Web 层服务层和 DAO 层提供了三个不同的包，但由于某种原因，我的应用程序无法创建 exerciseController 我已经将 exerciseController 类注释为控制器。练习类已被注释为一个实体。我也已经在控制器类中自动连接了ExerciseService。它在 DAO 层被注释为存储库，在服务层被注释为服务。即便如此，无论出于何种原因，它仍然无法创建 bean exerciseController。

更多信息：我使用 hibernate 作为我的 ORM，并且我也在使用 h2 数据库引擎。

感谢您的帮助！！ :)

这是我的一些代码

package com.omar.workoutlog;

@SpringBootApplication
@EnableAutoConfiguration
@ComponentScan
public class Application  {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

我的练习控制器类：

package com.omar.workoutlog.Controllers;
@Controller
public class ExerciseController {

    @Autowired
    private ExerciseService exerciseService;

    @RequestMapping("/")
    public String showExercise(){


        return "workout";
    }

}

我的 ExerciseServiceImpl ：

package com.omar.workoutlog.Service;    
@Service
public class ExerciseServiceImpl implements ExerciseService {

    @Autowired
    private ExerciseDao exerciseDao;

    @Override
    public List<Exercise> findAll() {
        return null;
    }

    @Override
    public Exercise findById(Long id) {
        return null;
    }

    @Override
    public void save(Exercise exercise, MultipartFile file) {

    }

    @Override
    public void delete(Exercise exercise) {

    }

    @Override
    public void toggleFavorite(Exercise exercise) {

    }

    @Override
    public String findByExercisename(int week) {
        return exerciseDao.getExerciseName(week);
    }
}

如果您需要查看更多代码，请告诉我

这是我的 DataConfig 类：

【问题讨论】：

  • 能否请您在问题中添加每个类的包名称，以及您从 Spring Boot 应用程序获得的完整堆栈跟踪。
  • 嘿，我已经按照您的要求对问题进行了修改，如果您发现我哪里出错了，请告诉我，感谢您的帮助！
  • 非常好的堆栈跟踪。堆栈跟踪告诉您数据库的用户名或密码无效，只需确保在应用程序上定义了 h2 数据库配置。属性
  • 您还可以将DataConfig.class 分享到问题中，这将有助于明确配置中的不匹配之处。您还在使用 application.properties 文件吗？还是直接在DataConfig.class定义配置？

【解决方案1】：

根据日志信息，你得到的异常如下：

BeanCreationException: Error creating bean with name 'sessionFactory'
defined in class path resource [com/omar/workoutlog/Config/DataConfig.class


Caused by: org.h2.jdbc.JdbcSQLException: Wrong user name or password [28000-191]

让我们验证com.omar.workoutlog.Config.DataConfig 是否已正确定义所有属性以建立与 H2 数据库的连接。下面是一个如何创建 DataSoruce bean 的示例。

@Bean
public DataSource dataSource() {
    DataSourceBuilder dataSourceBuilder = DataSourceBuilder.create();
    dataSourceBuilder.url("jdbc:h2:mem:testDb");
    dataSourceBuilder.driverClassName("org.h2.Driver");
    return dataSourceBuilder.build();
}
