Swagger 3 在 SpringBoot 3 中获取 Whitelabel 错误页面

Question

我正在 Springboot 3 中制作 API。当我添加此 dependency 时，我在 http://localhost:8080/swagger-ui/index.html 或其他链接处收到白标签错误页面。我还添加了@EnableWebMvc @ComponentScan(basePackages = {"org.springdoc"}) @SpringBootApplication注释，但他们没有解决我的问题。

我的pom.xml文件：

我的应用程序java文件：

package coding.userDataBase;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class UserDataBaseApplication {

    public static void main(String[] args) {
        SpringApplication.run(UserDataBaseApplication.class, args);
    }

}

如何解决 springboot 3 中的 swagger 3 出现白标错误。谢谢大家顺便说一句。

Answer 1

从 pom.xml 中删除其他 swagger 依赖项并使用它：

<dependency>
    <groupId>org.springdoc</groupId>
    <artifactId>springdoc-openapi-starter-webmvc-ui</artifactId>
    <version>2.1.0</version>
</dependency>

Answer 2

一般来说，接受的答案应该有效。但是，如果您发现从 IntelliJ 内部启动 Spring Boot 时出现Whitelabel 错误页面，请尝试以下操作：

• 转到文件 > 使缓存无效...，然后单击使缓存无效并重新启动
• 在终端中，执行

  mvn clean install -DskipTests

• 重新启动您的应用程序
• 尝试访问 http://localhost:8080/[context-root]/v3/api-docs 或 http://localhost:8080/[context-root]/swagger-ui/index.html 这对我有用（经过几个小时的谷歌搜索）...
