我正在使用 Spring Boot 测试微服务架构，但是当 Spring Session 尝试从 Redis 反序列化 session 时出现异常。
架构如下:
Redis <--(session) api="" gateway="" (oauth2="" atuhentication)--=""> Uaa Server
Redis <--( session="">
@SpringBootApplication
@EnableOAuth2Sso
@Controller
@EnableZuulProxy
@EnableRedisHttpSession
public class GatewayApplication {
@RequestMapping("/user")
@ResponseBody
public Map<String, Object> user(Principal user) {
Map<String, Object> map = new LinkedHashMap<String, Object>();
map.put("name", user.getName());
map.put("roles", AuthorityUtils.authorityListToSet(((Authentication) user)
.getAuthorities()));
return map;
}
public static void main(String[] args) {
SpringApplication.run(GatewayApplication.class, args);
}
@Configuration
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
protected static class SecurityConfiguration extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
// @formatter:off
http.httpBasic().and().logout().and().authorizeRequests()
.antMatchers("/index.html", "/login", "/").permitAll().anyRequest()
.authenticated().and().csrf().disable();
// @formatter:on
}
}
}

我得到以下堆栈跟踪。我确实注意到网关应用程序可以正确反序列化，但它在异常点上使用 DefaultListableBeanFactory。不过，管理应用程序使用此 StaticListableBeanFactory。

关于如何配置或修复此问题的任何想法？
最佳答案
问题似乎与以下修复有关
https://jira.spring.io/browse/SPR-15766
升级到 spring 4.3.10 应该会改善这种情况。
