添加不上依赖

id-spring-boot-starter

由于项目只使用了几个简单的注解就实现了单点登录的效果，不清楚过程是啥样，所以怎么实现单点登录的统一登出？

部分情况会出现java.lang.IllegalStateException:Calling [asyncError()] is not valid for a request with Async state。
解决方法：排除Tomcat依赖，使用Jetty代替。

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

您好 postman 返回
{
"imageUrl": "static/images//yogan.png",
"logoImageUrl": "static/images//watermark_yogan.png"
}
请问如何获取带水印的图片吗？

集成sso项目中，sso-client项目如何自定义权限校验呀，只能通过在方法上加注解吗，自己尝试了下rbac的方式，发现登录也会被拦截，不能重定向到sso-server的登录页面了，楼主知道的话，还望能够提供一些思路，谢谢，邮箱：[email protected]

Hi, we are a research group to help developers build secure applications. We designed a cryptographic misuse detector on Java language(Our main concern is the secure implementation and use of Json Web Token). We found your great public repository (i.e.,
Spring-Boot-In-Action) from Github, and several security issues detected by our detector are shown in the following. The specific security issues we found are as follows:
(1) Location: Package: cn.codesheep.springbt_security_jwt.controller; Class: JwtAuthController.class
and Package cn.codesheep.springbt_security_jwt.comm; Class:Const.class
Security issue: Using predictable/constant cryptographic key when creating and verifing Json Web Token.

Using a predictable/constant secret does not conform to the security implementation specification of JWT, which may bring security risks to your system. It is recommended to use a more secure way to store the secret used to generate the JWT and use a strong enough key to improve the security of the project. （For the hazards of predictable/constant secret, you can refer to CWE-321, NIST Special Publication 800-57).

We wish the above security issues cloud truly help you to build a secure application. If you have any concern or suggestion, please feel free to contact us, we are looking forwart to your reply. Thanks.

/springbt_security_jwt项目中，JWTFilter类中，
private UserDetailsService userDetailsService;使用@Autowired注解报错，
可以用@resource 代替

hi,hansonwang99.
我关注了你的这个项目，写的很不错，对我这个初级开发的帮助很大，这里先谢谢你啦！
但是我个人觉得在数据库/缓存相关这栏中，可以增加多数据源配置，springboot 集成 Jpa，springboot 集成 redis 这些内容，让你这个项目更加丰富。

异常信息如下

Resolved [org.springframework.http.converter.HttpMessageNotWritableException: Could not write JSON: (was java.lang.NullPointerException); nested exception is com.fasterxml.jackson.databind.JsonMappingException: (was java.lang.NullPointerException) (through reference chain: cn.codesheep.springbt_security_jwt.model.entity.User["authorities"])]

我自建一个模块不使用springbt security测试注册方法就是正常 望羊哥有空帮忙看看 谢谢
