我有以下源代码，我试图在spring boot中运行它，但绑定没有发生，它抱怨它无法找到转换器。
出现意外错误：
(type=Internal Server Error, status=500). No converter found for return value of type: class com.test.SearchVO。
据我所知，弹簧靴不需要杰克逊罐子在路径上。但我试过补充一点，但它仍无法正常工作。我在不同的论坛尝试过类似的问题找不到任何好的答案，请帮忙。
了解springboot是否会自动转换？
我尝试发布我无法获得值等的值。
我第一次参与弹簧应用并尝试弹簧靴，因为没有弹簧调度员。

将@EnableAutoConfiguration替换为@SpringBootApplication注释。
@SpringBootApplication 包含：
@Components（即@RestController, @Controller, @Repository, @Service）以下是Small Demo您的请求映射。
考虑将@RestController移动到abc.xyz.controller包下的单独类中，其中abc.xyz是包含SpringBootApplication类的包，这将确保@ComponentScan查找所有构造型。

请确保您对SearchVO类的字段具有公共获取方法。
