gateway+oauth2 error #2

Open yqbjtu opened 6 years ago

yqbjtu commented 6 years ago

I have the same issue, I just made a small modification in spring-cloud-gateway-sample. only adding the following two dependencies for I need to support oauth (if I does not use gateway , my oauth works well).

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

        <dependency>
        <groupId>org.springframework.security.oauth.boot</groupId>
        <artifactId>spring-security-oauth2-autoconfigure</artifactId>
        <version>2.0.0.RELEASE</version>
        </dependency>

then I added "@EnableOAuth2Sso" to main class. When I start my gateway project. it reports the following error: ... java.lang.Thread.run(Thread.java:748) 2018-08-08 19:46:09.047 WARN 16540 --- [ost-startStop-1] o.a.c.loader.WebappClassLoaderBase : The web application [ROOT] appears to have started a thread named [reactor-http-nio-7] but has failed to stop it.

If I remove the spring-boot-starter-web

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

when I started ,the error is like this 

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to process import candidates for configuration class [com.example.demogateway.DemogatewayApplication]; nested exception is java.lang.IllegalStateException: Failed to introspect annotated methods on class org.springframework.security.oauth2.config.annotation.web.configuration.OAuth2ClientConfiguration
...
Caused by: java.lang.NoClassDefFoundError: javax/servlet/Filter

then I added javax.servlet-api dependeancy, the new error is like this.

@yqbjtu - Did you get @EnableOAuth2Sso working with Spring Cloud Gateway?
