No qualifying bean of type 'XXX' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

出现错误"No qualifying bean of type 'XXX' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}"的原因是没有找到符合自动装配条件的bean。

通常，这种错误是由于注入的bean类型与实际存在的bean类型不匹配所导致的。解决这个问题有几种方法可以尝试。一种方法是检查注入的bean类型是否正确，确保它与实际存在的bean类型一致。另一种方法是检查是否存在重复的注解或配置，这可能导致重复注入相同类型的bean。

另外，这个错误也可能是由于项目的依赖问题造成的。可以通过检查项目的POM文件，确保只引入了必要的依赖，并排除无关的依赖。同时，确保POM文件的父级管理正确配置。如果遇到类似的问题，不能通过网络上的解决方案解决，可以仔细检查自己的POM文件，确保依赖配置正确。

综上所述，解决"No qualifying bean of type 'XXX' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}"错误的方法包括：
1. 检查注入的bean类型是否正确，并确保它与实际存在的bean类型一致。
2. 检查是否存在重复的注解或配置，避免重复注入相同类型的bean。
3. 检查项目的POM文件，确保只引入了必要的依赖，并排除无关的依赖，同时确保POM文件的父级管理正确配置。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
