UnsatisfiedDependencyException：创建名称为＆＃39; exerciseController＆＃39;的bean时出错

时间：2017-08-23 02:00:33

标签： java spring hibernate spring-mvc spring-boot

所以我正在使用Spring启动创建一个小型Web应用程序，但是当我运行它时，我收到此错误“错误创建名为exerciseController的bean。我已经将我的实体和控制器分开了。我还有三个不同的Web层服务层包和DAO层但由于某些原因我的应用无法创建exerciseController我已经将exerciseController类注释为Controller。练习课已注释为实体。我也已经在控制器类中自动装配了ExerciseService。它在DAO层中注释为存储库，并在服务层中注释为服务。即便如此，由于某种原因它仍然无法创建bean exerciseController。

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

感谢您的帮助!! ：）

以下是我的一些代码

package com.omar.workoutlog;

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

我的ExerciseController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

这是完整的堆栈跟踪：

这是我的DataConfig类：

    package com.omar.logbook.Config;

import org.springframework.context.annotation.Bean;

workoutlog.db.driver = org.h2.Driver
workoutlog.db.url = jdbc:h2:tcp://localhost/~/Documents/workoutlog/data/workoutlog

2 个答案:

答案 0 :(得分：0)

尝试在SpringBootApplication注释中给出控制器包名称，如下所示

@SpringBootApplication(scanBasePackages = { "com.test.dashboard" }, scanBasePackageClasses = {
    com.test.dashboard.controller.DashboardPageController.class })

答案 1 :(得分：0)

根据日志信息，您获得的异常如下：

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已正确定义所有属性以建立与H2数据库的连接。以下是创建DataSoruce bean的一个示例。

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