spring security 中异常 org.springframework.expression.spel.SpelEvaluationException

异常：org.springframework.expression.spel.SpelEvaluationException: EL1057E: No bean resolver registered in the context to resolve access to bean ‘myrbacService’

在springboot中添加了springsecurity，在配置权限的时候发生了这个异常

@Override
public void config(ExpressionUrlAuthorizationConfigurer<HttpSecurity>.ExpressionInterceptUrlRegistry config) {
    config.anyRequest().access("@myrbacService.hasPermission(request, authentication)");
}

原因是这个bean需要加在上下文对象中，只需添加2个配置即可

@Bean
public OAuth2WebSecurityExpressionHandler oAuth2WebSecurityExpressionHandler(ApplicationContext applicationContext) {
    OAuth2WebSecurityExpressionHandler expressionHandler = new OAuth2WebSecurityExpressionHandler();
    expressionHandler.setApplicationContext(applicationContext);
    return expressionHandler;
}

在ResourceServerConfigurerAdapter的实现类中配置如下

@Autowire
private OAuth2WebSecurityExpressionHandler expressionHandler;
@Override
public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
    resources.expressionHandler(expressionHandler);
}
