Spring Cloud Gateway 和 Swagger 是否存在兼容性问题,出现错误

Does Spring Cloud Gateway and Swagger have compatibility issue, getting errors

我正在动手使用 Spring Cloud Gateway 和 Swagger 创建微服务。无法启动我的应用程序。它给出 Failed to introspect annotated methods on class springfox.documentation.swagger2.configuration.Swagger2DocumentationConfiguration 需要 spring 的错误-boot-starter-web 依赖项。但是在包含此依赖项时,出现错误 Spring MVC found on classpath,此时与 Spring Cloud Gateway 不兼容。请删除 spring-boot-starter-web 依赖项。

我们不能将 Swagger 与 Spring 云网关一起使用吗?

Spring Cloud Gateway 建立在 Project Reactor 之上并且已经包含一个 Netty(而不是 Tomcat 服务器)。

所以请尝试删除:

<dependency> 
    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

而且 Springfox 还不支持 Spring Webflux,但是有一个解决方案可以让它工作,为此你需要按照下面描述的步骤进行操作。

将依赖项替换为以下内容:

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>3.0.0-SNAPSHOT</version>
</dependency>
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>3.0.0-SNAPSHOT</version>
</dependency>

添加这个依赖:

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-spring-webflux</artifactId>
    <version>3.0.0-SNAPSHOT</version>
</dependency>

添加存储库:

<repositories>
    <repository>
        <id>spring-milestone</id>
        <name>Spring Maven MILESTONE Repository</name>
        <url>https://repo.spring.io/libs-milestone</url>
    </repository>
    <repository>
        <id>jcenter-snapshots</id>
        <name>jcenter</name>
        <url>http://oss.jfrog.org/artifactory/oss-snapshot-local/</url>
    </repository>
</repositories>

将注释更改为:

@EnableSwagger2WebFlux

可以在 this link 找到工作草案。

@V.Mokrecov,我不同意你关于Springfox对SpringWebFlux的支持。

对于 Springfox 和 SpringWebFlux,仅以下依赖项就足够了:

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-webflux</artifactId>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-boot-starter</artifactId>
            <version>3.0.0</version>
        </dependency>

随着 Springfox 3.0.0 的发布,现在也不需要包含注解了。您可以省略@EnableSwagger2 和@EnableSwagger2WebFlux。

包括这些依赖项对我有用。
