【中文标题】EnableEurekaClient 不能与 EnableOAuth2Sso 一起使用。它导致 springSecurityFilterChain bean AlreadyBuiltException【英文标题】:EnableEurekaClient cannot work with EnableOAuth2Sso. It causes springSecurityFilterChain bean AlreadyBuiltException 【发布时间】:2016-03-04 09:13:08 【问题描述】:我正在使用 spring-cloud-starter-parent 版本 Brixton.M3 来测试 spring security oauth2。在我启用 Eureka 客户端之前一切正常。
开启Eureka客户端后报如下错误,
[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.3.0.RELEASE:run (default-cli) on project spring-security-oauth2-brixton-demo: An exception occured while running. null: InvocationTargetException: Error creating bean with name 'springSecurityFilterChain' defined in class path resource [org/springframework/security/config/annotation/web/configuration/WebSecurityConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.servlet.Filter]: Factory method 'springSecurityFilterChain' threw exception; nested exception is org.springframework.security.config.annotation.AlreadyBuiltException: This object has already been built -> [Help 1]

【问题讨论】:
【参考方案1】:如此处所述:https://github.com/spring-cloud/spring-cloud-netflix/issues/673,删除 spring-cloud-security 依赖项将解决问题。
【讨论】:
【参考方案2】:我很确定您的ResourceServerConfigurerAdapter
中需要一个请求匹配器。示例:http.antMatcher("/**")
。
