springsession生成sessionid不一致問題解決

不廢話，本人遇到的問題主要是兩個不同的springboot版本，需要共享sessionid。

1.配置application

#cookie作用域
server.servlet.session.cookie.path=/
server.servlet.session.cookie.max-age=-1
server.servlet.session.cookie.http-only=false
server.servlet.session.cookie.name=SESSIONIDS


2.繼承springsession默認的DefaultCookieSerializer類，可以設置cookie的基本參數

public class DynamicCookieMaxAgeCookieSerializer extends DefaultCookieSerializer {
    private static final Logger LOGGER = LoggerFactory.getLogger(DynamicCookieMaxAgeCookieSerializer.class);

    public static final String COOKIE_MAX_AGE = "cookie.max-age";
    @Value("${server.servlet.session.cookie.path}")
    private String cookiePathValue  ;
    @Value("${server.servlet.session.cookie.max-age}")
    private Integer cookieMaxAge;

    @Override
    public void writeCookieValue(CookieValue cookieValue) {
        HttpServletRequest request = cookieValue.getRequest();
        // 從request域讀取到cookie的maxAge屬性
        Object attribute = request.getAttribute(COOKIE_MAX_AGE);
        if (attribute != null) {
            cookieValue.setCookieMaxAge((int) attribute);
        } else {
            // 如果未設置，就使用默認cookie的生命周期
            cookieValue.setCookieMaxAge(this.cookieMaxAge);
        }
        if (LOGGER.isDebugEnabled()) {
            LOGGER.debug("動態設置cooke.max-age={}", cookieValue.getCookieMaxAge());
        }
        super.writeCookieValue(cookieValue);
    }

    @Override
    public void setCookiePath(String cookiePath) {
        super.setCookiePath(cookiePathValue);
    }
}
3.IOC

@Configuration
//@EnableRedisHttpSession(maxInactiveIntervalInSeconds = 1800)
public class SpringSessionConfiguration {
    @Value("${server.servlet.session.cookie.name}")
    private String cookieName;

   /* @Value("${server.servlet.session.cookie.secure}")
    private Boolean cookieSecure;*/

// @Value("${server.servlet.session.cookie.max-age}")
// private Integer cookieMaxAge;
    //server.servlet.session.cookie.path
    @Value("${server.servlet.session.cookie.path}")
    private String cookiePath;

    @Value("${server.servlet.session.cookie.http-only}")
    private Boolean cookieHttpOnly;

   /* @Value("${server.servlet.session.cookie.same-site}")
    private String cookieSameSite;*/

    @Bean
    public CookieSerializer cookieSerializer() {
        DynamicCookieMaxAgeCookieSerializer serializer = new DynamicCookieMaxAgeCookieSerializer();
        serializer.setCookieName(this.cookieName);
        // serializer.setCookieMaxAge(this.cookieMaxAge);
        //serializer.setSameSite(this.cookieSameSite);
        serializer.setUseHttpOnlyCookie(this.cookieHttpOnly);
        serializer.setCookiePath(cookiePath);
        serializer.setSameSite(null);
        return serializer;
    }
}
