spring boot 拦截器中无法注入serivce

摘要: 最近在项目中用拦截器去拦截用户操作，并对操作日志进行记录， 在拦截器中记录日志时调用service 层 的save方法，发现service为null ,通过
@Autowired
private LogService logService;
这种方式无法注入；解决办法看以下代码。

[code=language-java]@Configuration
public class OptPermissionHandlerInterceptor extends HandlerInterceptorAdapter {
private Logger logger = LoggerFactory.getLogger(OptPermissionHandlerInterceptor.class);

@Autowired
private OperatorLogService operatorLogService; //这里使用@Autowired无法注入成功

@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws      Exception {
if (true) {
return true;
} else {
String result = "当前登录用户无权限！";
response.getOutputStream().write(result.getBytes());
response.setStatus(HttpStatus.OK.value());
return false;
}
}

@SuppressWarnings("rawtypes")
@Override
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
try {
if (handler instanceof HandlerMethod) {
HandlerMethod handlerMethod = (HandlerMethod) handler;
String beanName = handlerMethod.getBean().getClass().toString();
String methodName = handlerMethod.getMethod().getName();
String uri = request.getRequestURI();
String remoteAddr = request.getRemoteAddr();
String sessionId = request.getSession().getId();

OperatorLog optLog = new OperatorLog();
optLog.setBeanName(beanName);
optLog.setMethodName(methodName);
optLog.setRemoteAddr(remoteAddr);
optLog.setSessionId(sessionId);
optLog.setUri(uri);

if (operatorLogService == null) {//解决service为null无法注入问题
System.out.println("operatorLogService is null!!!");
BeanFactory factory = WebApplicationContextUtils.getRequiredWebApplicationContext(request.getServletContext());
operatorLogService = (OperatorLogService) factory.getBean("operatorLogService");
}
operatorLogService.saveOperatorLog(optLog);
}
} catch (Exception e) {
logger.error("", e);
}
}

@Override
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler,
Exception ex) throws Exception {

}

}
