 有19个模块
 暂时升级一个模块，发现session不能共享

  https://blog.youkuaiyun.com/qq_24484911/article/details/103478476


两个项目需要集成，并实现session共享，使用spring session实现，但一直不成功。

原因是一个项目的springboot版本较高（2.1.3.RELEASE），会将session使用base64转码

@Configuration
public class RedisSessionConfig {
 
	/**
	 * @Description 解决高版本的springboot会自动将session用base64转码。
	 * 				导致与底版本springboot无法session共享。
	 * 				此配置为禁止转码
	 */
	@Bean
	public DefaultCookieSerializer getDefaultCookieSerializer(){
		DefaultCookieSerializer cookieSerializer = new DefaultCookieSerializer();
		cookieSerializer.setUseBase64Encoding(false);
		return cookieSerializer;
	}
}

 ClassNotFoundException: org.springframework.boot.bind.RelaxedDataBinder]
