springboot：shiro注入dubbo服务空指针问题

问题描述最近搭建springboot+dubbo+shiro微服务时，自定义的shiro的realm组件中：@Componentpublic class AuthRealm extends AuthorizingRealm { @Reference private AccountService accountService;调用dubbo服务accountService时，出现了空指针的异常。问题原因dubbo的@Reference机制，是在spring bean全部注册完成后，再注入的spring bean中。而shiro的authRealm调用代码： @Autowired private AuthRealm authRealm; @Bean public SessionsSecurityManager securityManager(){ DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager(); securityManager.setRealm(authRealm); return securityManager; }在代码中我们可以看到，注册securityManager这个bean的时候，会将authRealm赋值给securityManager，但是此时accountService还未注入到authRealm中去，所以securityManager的authRealm属性中accountService字段为null。解决方案在将authRealm赋值给securityManager时，手动将accountService注入到authRealm中。@Componentpublic class AuthRealm extends AuthorizingRealm { private AccountService accountService; @Autowired private DubboProperties properties; … /** * 手动注入dubbo服务 */ public void setAccountService() { ReferenceConfig<AccountService> referenceConfig = new ReferenceConfig<>(); referenceConfig.setApplication(properties.getApplication()); referenceConfig.setRegistry(properties.getRegistry()); referenceConfig.setInterface(AccountService.class); this.accountService = referenceConfig.get(); }}@Configurationpublic class ShiroConfig { @Autowired private AuthRealm authRealm; @Bean public SessionsSecurityManager securityManager(){ DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager(); authRealm.setAccountService(); securityManager.setRealm(authRealm); return securityManager; } …}项目源码：https://github.com/ksyzz/spri…
