org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'dataSource' defined in class path resource

根据提供的引用内容,可以看出出现了一个名为'org.springframework.beans.factory.UnsatisfiedDependencyException'的异常,该异常是由于在创建名为'dataSource'的bean时出现了依赖不满足的情况而导致的。具体来说,是在配置Druid连接池时,使用set方法对name属性进行赋值时,参数值写错了,导致了该异常的出现。解决该异常的方法是检查Druid连接池的配置是否正确,特别是对于name属性的赋值是否正确。

写了自动装配和注解扫描为什么还会报这个错 Error creating bean with name 'bookController': Unsatisfied dependency expressed through field 'serviceBook'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'serviceBookImpl': Unsatisfied dependency expressed through field 'bookDao'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'bookDaoImpl': Unsatisfied dependency expressed through field 'jdbcTemplate'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.jdbc.core.JdbcTemplate#0' defined in class path resource [tx-annotation.xml]: Cannot resolve reference to bean 'dataSource' while setting bean property 'dataSource'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [tx-annotation.xml]: Initialization of bean failed; nested exception is java.lang.NoSuchMethodError: org.springframework.core.annotation.AnnotationUtils.isCandidateClass(Ljava/lang/Class;Ljava/lang/Class;)Z
这个错误是因为在创建 `bookController` bean 时,其依赖的 `serviceBook` 字段无法满足。同样地,创建 `serviceBookImpl` bean 时,其依赖的 `bookDao` 字段也无法满足。最后,创建 `bookDaoImpl` bean 时,其依赖的 `jdbcTemplate` 字段也无法满足。
具体原因是在 `tx-annotation.xml` 配置文件中,创建 `org.springframework.jdbc.core.JdbcTemplate` bean 时,无法解析对 `dataSource` bean 的引用。而在 `tx-annotation.xml` 中定义的 `dataSource` bean 初始化失败,报错为 `java.lang.NoSuchMethodError: org.springframework.core.annotation.AnnotationUtils.isCandidateClass(Ljava/lang/Class;Ljava/lang/Class;)Z`。
这个错误可能是由于依赖版本不兼容导致的。你可以检查一下项目中使用的 Spring 相关依赖的版本是否一致,并且与你所使用的 Spring 版本兼容。另外,还要确保相关的类和方法都正确引入和导入。
希望这些信息能对你有所帮助!如果还有其他问题,请继续提问。

这个错误看起来是在使用Spring框架时出现的。它表明在创建名为'securityConfig'的bean时出现了依赖注入错误,而这可能是由于名为'securityUserDetailsServiceImpl'的bean中的依赖注入失败所导致的。同时,'customMapper' bean中的'sqlSessionFactory'属性也无法满足依赖关系,这可能又是由于'sqlSessionFactory' bean中的依赖注入失败所导致的。最后,'dataSource' bean的初始化方法调用失败,原因可能是默认的primary数据库设置有误。建议检查这些bean及其依赖关系,以找出问题并解决它们。
