#No qualifying bean of type [com.dao.ResourceDao] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency

本文介绍了解决项目启动过程中出现的Noqualifyingbeanoftype问题的方法。主要关注于检查DAO和服务层的实现类是否正确地使用了@Repository和@Service注解。

在项目启动过程中，如果出现No qualifying bean of type [com.dao.ResourceDao] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency问题，意思是至少需要一个bean作为com.dao.ResourceDao的实现类添加注解@Repository，则需要检测ResourceDao的实现类有没有添加@Repository这个注解，如果没有添加，则添加上；类似，如果是Service层出现此类问题，给Service的实现类添加@Service这个注解。

如openAiChatModel的路径见：org.springframework.ai.autoconfigure.openai.OpenAiAutoConfiguration.java。@Qualifier注解是用来指定注入的bean的名字，value值需要到源码中查看，在Spring框架中，出现。

上午改了一下项目运行开始这个错误 先看错误提示修改，找到配置文件的问题 注入问题，由于有两个类实现了xx，所以Spring不知道应该绑定哪个实现类，所以抛出了如上错误。 这时候就得用到@Qualifier("xxxx")注解了 通过这个注解表明了哪个类才是我们需要的。 添加完注解后运行，出现新的问题，提示找不到注解的类 就添加了自动扫描这个类的包路径 运行还是提示这个错误，继续找原因...

把@Autowired 改成以下 @Autowired(required = false) @Autowired(required=false)：表示忽略当前要注入的bean，如果有直接注入，没有跳过，不会报错。 在容器的启动过程中，会初始化很多bean，这也是spring的核心之一（IOC）。但是在注入的过程中，扫描到公共方法中要注入的bean，并未找到，强行注入就会注入失败。我们又不能单独的去除改方法，所以我们采取的思想就是有bean就注入，没有就不注入。 ...

确保 MyBatis 或者 MyBatis-Plus 的配置文件正确配置了 Mapper 接口的扫描路径。MyBatis 或者 MyBatis-Plus 的配置文件可能存在错误，导致 Mapper 接口无法被正确加载。在 MyBatis 或者 MyBatis-Plus 里，通常需要给 Mapper 接口添加特定的注解，像。如果你使用的是 Spring Boot 和 MyBatis-Plus，可以在主应用类上添加。从你给出的错误信息可知，Spring 应用在启动时碰到了依赖注入问题，具体是在创建。

日志信息显示红框这个 类没有效 bean，第一反应看到这个类，以为没有这个类接口，发现有这个类时间 ，想想草率了，仔细一看这个错误：expected at least 1 bean which qualifies as autowire candidate，意思：期望至少有一个有效的可选 bean,框中的是接口，装配的是实现类，于是查找它的实现，蒙蔽了没有写实现类，出现这个情况是 copy的漏掉了，太难了。一个小小错误让我认识到，大部分答案都在日志中，错误信息一定要仔细看清楚，再找解决问题，自己有毒！

出现该问题的原因主要是编译等级跟jdk不一致。 先查看你jdk版本 我这里是1.7,设置下Java compiler 和 Project Facets，问题解决！！

引用中提到了一个错误信息，它指示在自动注入依赖时找不到符合条件的bean。类似的错误信息在引用中也有提到。原因可能是重复注入相同的bean接口类。解决这个问题的方法有两种，一种是去掉重复的注解，另一种是去掉重复的接口注解或类注解。 另外，引用中提到了另一种可能的情况，即自动注入失败。在测试类中遇到了这个问题，实际上自动注入的是FeginClient而不是Service。通过将@Autowired的required属性设置为false可以解决这个问题。 总结起来，这些引用内容提供了一些关于自动注入依赖时出现问题的可能原因和解决方法。你可能需要检查重复注解和依赖的类型，以确保正确地注入bean。<span class="em">1</span><span class="em">2</span><span class="em">3</span> #### 引用[.reference_title] - *1* *3* [expected at least 1 bean which qualifies as autowire candidate for this dependency.](https://blog.csdn.net/weixin_42190471/article/details/117827289)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v93^chatsearchT3_1"}}] [.reference_item style="max-width: 50%"] - *2* [available: expected at least 1 bean which qualifies as autowire candidate.
