問題的原因加載順序引起的。
方案一:用spring-dubbo配置文件的形式, 這個注入應該沒問題
主要說方案二:采用dubbo注解@Reference注入, 在實際情況中, 由於shiro和dubbo加載順序的原因, 會導致使用@Reference的bean注入到Realm中為null, 故在其他地方可以引用 該dubbo bean, 然后轉化為spring bean,再用spring上下文調用即可得到轉化后的dubbo bean即可。(配置文件的形式會 先把dubbo bean轉化為spring bean, 再采用@Autowired注入在加載順序上不會和dubbo沖突, 故可以成功注入)
方法:
1. 在Controller上引用該dubbo bean
@Reference(version = "1.0.0")
IAccountService iAccountService;
@Bean(name = "iAccountService")
public IAccountService getIAccountService(){
return iAccountService;
}
2.添加上下文工具類
@Component
public class SpringBeanFactoryUtils implements ApplicationContextAware {
private static ApplicationContext context = null;
public static <T> T getBean(Class<T> type) {
return context.getBean(type);
}
public static <T> T getBean(String name, Class<T> type) {
return context.getBean(name, type);
}
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
System.err.println("SpringBeanFactoryUtils be inited...");
if (SpringBeanFactoryUtils.context == null) {
SpringBeanFactoryUtils.context = applicationContext;
}
}
}
3.在Realm中引用bean
public class MyShiroRealm extends AuthorizingRealm {
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
String userName = (String) token.getPrincipal();
IAccountService iAccountService = SpringBeanFactoryUtils.getBean("iAccountService",IAccountService.class);
Account account = iAccountService.selectAccountByLogin(userName, null);
if (account == null) {
throw new UnknownAccountException();// 用戶名密碼不正確
}
。。。。。。
