造成的：org.springframework.beans.BeanInstantiationException

我有一个非常基本的程序，但不管我的代码改变我总是得到同样的错误信息：造成的：org.springframework.beans.BeanInstantiationException

我的代码：

@SpringBootApplication 
public class DemoApplication { 

    private static final Logger log = LoggerFactory.getLogger(DemoApplication.class); 

    @Autowired 
    private ApplicationContext context; 

    public static void main(String[] args) { 
     SpringApplication.run(DemoApplication.class, args); 
    } 

    @Autowired 
    QueryRepoImp queryRepoImp; 

    @Bean 
    public CommandLineRunner clr() { 

     return a -> { 
      /* 
      System.out.println("Create Queries"); 
      Query c1 = new Query("Wood"); 
      Query c2 = new Query("Stones"); 

      // insert 
      repo.add(c1); 
      repo.add(c2); 

      for (Query t : repo.findAll()) { 
       System.out.println("Query: " + t.getRelation()); 
      } 


      */ 
     }; 
    } 
}

QueryRepoImp.java

@Repository 
public class QueryRepoImp implements QueryIRepoInt { 

    private final String SQL_INSERT = "INSERT INTO query (section) VALUES (?)"; 
    private final String SQL_FINDALL = "SELECT * FROM query ORDER BY lastname"; 
    Logger logger = Logger.getLogger("QueryLogger", QueryRepoImp.class.getName()); 

    @Autowired 
    JdbcOperations jdbcTemplate; 

    @Override 
    public void add(Query query) { 
     Object[] objects = {query}; 
     List<Object[]> list = new LinkedList<>(); 
     list.add(objects); 
     jdbcTemplate.batchUpdate(SQL_INSERT, list); 
    } 
}

QueryIRepoInt.java

@Component 
public interface QueryIRepoInt { 
    void add(Query query); 
}

谁能告诉我，请在错误皮？谢谢！

而你配置上下文文件/类是...？ – Andremoniy

嗨安娜，你可以添加一个单独的配置文件@Configuration文件或添加 – Pradeep

尝试从实施类中删除'@ Repository'并将'@ Component'更改为'@Repository' – user1211

仔细阅读堆栈跟踪。你的问题的原因写在那里。

Caused by: java.util.MissingResourceException: Can't find com.example.demo.QueryRepoImp bundle

此资源包缺失。检查它是否属于您的项目并重新检查。（或者您想使用LoggerFactory来获取记录器实例。）

如果您有像这样的嵌套异常，请检查每个异常。

我刚刚删除了记录器部分，现在它正在工作。但说实话，我不明白为什么。我认为这是因为Logger类不是用@Beans注释的吗？我需要记录仪时如何解决这个问题？但是哇，我坐在前面2个小时寻找完全不同的方向。所以，到目前为止谢谢你:) – AnnaKlein

不，你正在使用一种需要ResourceBundle的方法。查看Javadoc的java.util.logging.Logger＃getLogger（String，String）。但使用LoggerFactory通常是更好的方法 –

请在DemoApplication类中使用以下标签。

@EnableTransactionManagement 
@EnableAutoConfiguration 
@ComponentScan({"Packages you want to scan"}) 
@EnableJpaRepositories("Repository package") 
@SpringBootApplication 
public class DemoApplication 
{ 
     /*Main method*/ 
}
