Spring Boot 自定义 Shiro 过滤器无法使用 @Autowired问题及解决方法

@Bean
public JwtTokenFilter JwtTokenFilter() {
  return new JwtTokenFilter();
}

@Bean(name = "shiroFilter")
public ShiroFilterFactoryBean shiroFilterFactoryBean() {
  ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
  shiroFilterFactoryBean.setSecurityManager(securityManager());
  // 注册自定义过滤器
  Map<String, Filter> filterMap = new LinkedHashMap<>(8);
  // 这里只能使用 new 新建实例
  filterMap.put("authc", new JwtTokenFilter());
  shiroFilterFactoryBean.setFilters(filterMap);
  Map<String, String> filterChains = new LinkedHashMap<>(8);
  filterChains.put("/v1/admin/login", "anon");
  filterChains.put("/**", "authc");
  shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChains);
  return shiroFilterFactoryBean;
}
