NoSuchMethodError 使用 spring-boot

Question

我没有为这个项目改过它的pom.xml，但是我最近开始这个项目的时候，它报了这个错误：java.lang.NoSuchMethodError。 看到报错，好像是找不到我写的接口方法。

2020-07-21 10:23:05.212 ERROR [main] ApiDescriptionReader::read[#87] : Skipping process path[/projects], method[addProject] as it has an error.java.lang.NoSuchMethodError: org.springframework.http.MediaType.equalsTypeAndSubtype(Lorg/springframework/util/MimeType;)Z
    at springfox.documentation.builders.BodyParameterSpecificationProvider.lambda$create$0(BodyParameterSpecificationProvider.java:37)
... ...

我试过mvn clean install，还是不行。 这是 io.springfox 依赖树：

Answer 1

根据文档，这种方法自 spring 5.1.4 起就存在

https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/util/MimeType.html#equalsTypeAndSubtype-org.springframework.util.MimeType-

您可以更新您使用的 spring 的版本或降低 spring-fox 的版本
