回答: 根据你提供的引用内容,可能出现"No bean named 'ObjectMapper' available"的错误是因为在Spring的配置文件中没有定义名为"ObjectMapper"的bean。当使用bean的名称去搜索时,如果名称大小写不匹配,或者没有定义对应的bean,就会出现这个错误。\[1\]\[2\]为了解决这个问题,你可以按照以下步骤进行排查:
1. 检查报错信息,确保"ObjectMapper"这个bean是否已经被正确注入。
2. 检查Spring的配置文件,确认是否正确扫描了包含"ObjectMapper"的类所在的包。
3. 如果使用了注解配置,检查是否正确地添加了相关注解。\[3\]
希望这些信息对你有帮助!
