书接上回点这里

用了插件第二天就不能用了，然后我尝试下了各个版本的chrome＋各种解决方法都解决失败了。

最终看到一位大佬的解决方法，在springboot加个配置类去解决

import org.springframework.boot.autoconfigure.session.DefaultCookieSerializerCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.session.MapSessionRepository;
import org.springframework.session.SessionRepository;
import org.springframework.session.config.annotation.web.http.EnableSpringHttpSession;
import org.springframework.session.web.http.DefaultCookieSerializer;

import java.util.concurrent.ConcurrentHashMap;

@Configuration
@EnableSpringHttpSession
public class SessionConfig {
    @Bean
    public SessionRepository sessionRepository() {
        return new MapSessionRepository(new ConcurrentHashMap<>());
    }

    @Bean
    DefaultCookieSerializerCustomizer cookieSerializerCustomizer() {
        return new DefaultCookieSerializerCustomizer() {
            @Override
            public void customize(DefaultCookieSerializer cookieSerializer) {
                cookieSerializer.setSameSite("None");
                cookieSerializer.setUseSecureCookie(true); // 此项必须，否则set-cookie会被chrome浏览器阻拦
            }
        };
    }
}

导入依赖

<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-core</artifactId>
</dependency>

问题解决
