BeanCreationException的解决办法之一

如何调试ContextLoader-上下文初始化失败和BeanCreationException（获取上下文初始化参数）

我看到许多有关解决该问题的人们的帖子： ERROR context.ContextLoader-上下文初始化失败
org.springframework.beans.factory.BeanCreationException：

有没有一种方法可以打开调试来隔离问题？

它抱怨“ 没有这样的属性：针对类：groovy.lang.MetaClassImpl的getOrg
”，但这不是我们的类之一，是否有某种方法可以获取与我们的代码库相关的信息？

在我们的案例中，我们已经部署了Grails
1.2.1应用程序，并且在Tomcat中运行得很好。然后，我们停止了Tomcat进行数据库备份，然后重新启动了该应用程序。现在，没有环境更改（即，配置文件也没有更改等）的同一WAR会引发此错误。我们之前也间歇性地观察过此行为，但是重新启动可修复问题。

在我们的开发环境中，同一个应用程序可以与“ grails prod run-app”以及“ grails prod run-war”一起正常运行。

如果将日志记录级别设置DEBUG为org.springframework，org.codehaus.groovy则可以获取更多详细信息。

但在Grails的情况下，有时它可以帮助刚刚停止Tomcat，删除work和temp目录，并启动tomcat一次。

BeancreationException + NosuchBeandefinition异常

我正在使用SpringBoot开发Spring 4应用程序。

在com.test.tm包中，
应用程序类：

@SpringBootApplication   @EnableJpaRepositories( repositoryFactoryBeanClass = GenericRepositoryFactoryBean.class )  @Import( { HikariDataSourceConfig.class } )  public class Application {     public static void main( String[] args )   {    SpringApplication.run(Application.class, args);   }  }

在com.test.tm.entities包中，
用户类别：

@Table( name = "test.user" )@Entitypublic class User implements Serializable {    @Id  @GeneratedValue( strategy = GenerationType.AUTO )  private Integer id;  private String message;    ....  }

在com.test.tm.user
UserService.class中：

@Service@Transactional( rollbackFor = Exception.class )public class UserService {@Autowiredprivate GenericRepository<User, Serializable> gr; public User saveEntity( User usr ) {    return gr.save(usr); } public String getUser() {    //Get User logic }  }

GenericRepository.java：

@NoRepositoryBeanpublic interface GenericRepository<T, ID extends Serializable> extends PagingAndSortingRepository<T, ID> {    public List<T> findByNamedQuery( String name );    public List<T> findByNamedQueryAndParams( String name, Map<String, Object> params ); }

还有一种GenericRepositoryImpl.java实现上述方法的逻辑的地方。

在运行Application.java时，出现以下错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name ''userService'': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.test.utils.spring.repo.GenericRepository com.test.tm.user.UserService.gr; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type[com.test.utils.spring.repo.GenericRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.Dependency annotations: {@ org.springframework.beans.factory.annotation.Autowired(required = true) }

我没有定义名为userService的变量，但是仍然显示错误。
我可以通过任何方式解决上述问题。

广告。1. userService如文档所示，Spring 使用默认名称创建bean 。

广告。2.我不起诉，但是也许GenericRepositoryImpl不在
com.test.tm包裹内？如果是，则@ComponentScan使用正确的包声明指定其他注释，即。@ComponentScan("com.test.utils")，或者-
如果您使用的是Boot
1.3+-修改@SpringBootApplication(scanBasePackages={"com.test.utils","com.test.tm"})

BeanCreationException: Error creating bean with name ''dataSource'' defined in class path r...

现场情景：

初次搭建 springboot 工程，原本要搭建一个 springboot+mybatis 的 maven 工程，听说 springboot 会把一切给配置好，天真的在执行完 mybatis 自动生成 mapper 文件后进行打包，当前 springboot 工程只有一个空的 application.properties 文件，没有进行任何配置，故进行打包时（执行 run as maven install 命令）报以下错误：

Description:

Failed to configure a DataSource: ''url'' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class


Action:

Consider the following:
    If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
    If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

观察错误意为有数据源的依赖包但没有配置数据源：

添加两个配置文件（个人偏好使用 yml 文件，故删掉类 application.properties 文件添加了 yml 文件进行配置）：

application.yml：

spring:
  profiles:
    active: dev

application-dev.yml：

server:
  port: 8080
 
spring:
  datasource:
    username: root
    password: wbj@1992*
    url: jdbc:mysql://localhost:3306/swyx_form?useUnicode=true&characterEncoding=utf-8&useSSL=true&serverTimezone=UTC
    driver-class-name: com.mysql.jdbc.Driver
 
mybatis:
  mapper-locations: classpath:mapping/*Mapper.xml
  type-aliases-package: com.example.entity
 
#showSql
logging:
  level:
    com:
      example:
        mapper : debug

重新执行打包命令，再无异常

BeanCreationException异常

最近在搞Ibatis跟spring集成的时候，遇到这样一个问题，我在dao继承SqlMapClientDaoSupport时，报了下面这错误，一直纠结，请教各位大侠

各位大侠多多指教

BeanCreationException的解决办法之一

org.springframework.beans.factory.BeanCreationException: Error creating bean with name ''userServiceImpl'': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.atxieyun.crowdfunding.cpes2.dao.UserDao

解决方法：你看到没有我的就是因为这个 com.atxieyun.crowdfunding.cpes2.dao.UserDao 与图中的value中的不一样导致的，应该是com.atxieyun.crowdfunding.cpes2.dao.UserDao这样的，因此需要平时多注意一下，很多错误都是自己疏忽造成的。

我们今天的关于如何调试ContextLoader-上下文初始化失败和BeanCreationException和获取上下文初始化参数的分享已经告一段落，感谢您的关注，如果您想了解更多关于BeancreationException + NosuchBeandefinition异常、BeanCreationException: Error creating bean with name ''dataSource'' defined in class path r...、BeanCreationException异常、BeanCreationException的解决办法之一的相关信息，请在本站查询。
