我使用的 SpringBoot、knife4j 版本jar包如下所示:
org.springframework.boot
spring-boot-starter-parent
2.3.5.RELEASE
com.github.xiaoymin
knife4j-spring-boot-starter
2.0.7
下文中 Knife4jConfiguration.java 文件,其代码是我直接从 springboot-demo 项目中直接拷贝过来放到 MyBatis-SpringBoot 项目中。
springboot-demo项目Controller层包路径为: com.moon.controller ,MyBatis-SpringBoot 项目Controller层包路径为:com.moon.mybatis.controller 。 由于我忘记修改 Knife4jConfiguration.java 文件中 “RequestHandlerSelectors.basePackage(…)” 包路径,导致项目运行后,Swagger文档中没有接口信息。
Controller层包路径修改正确后,运行项目,Swagger文档中接口信息正常展示。

.enable(true)
.select()
//这里指定Controller扫描包路径
// .apis(RequestHandlerSelectors.basePackage("com.moon.controller"))
.apis(RequestHandlerSelectors.basePackage("com.moon.mybatis.controller"))
.paths(PathSelectors.any())
.build();
return docket;
}
private Tag[] getTags() {
return new Tag[] {
new Tag("alibaba", "阿里巴巴API接口"),
new Tag("tencent", "腾讯API接口")
};
}
}
程序运行后,Swagger接口文档信息展示如下所示:
Swagger 接口文档访问地址为:http://localhost:8080/doc.html#/home
本案例项目Demo地址为: Mybatis框架学习 。
如果大家觉得我的项目还行,可以加一个 Start ,感谢各位老铁了。
