Filter里面注入失败。

解决方法在init初始化这里对Service进行手动注入


public class RESTApiAuthenticationFilter implements Filter {
    protected Logger logger = LoggerFactory.getLogger(getClass());
	@Autowired
	private ApiUserService apiUserService;
	@Autowired
	private SignaConfig signaConfig;
	@Override
	public void init(FilterConfig filterConfig)  {
		logger.info("RESTApiAuthentication filter has been launched!");
        //手动注入
		BeanFactory factory = WebApplicationContextUtils.getRequiredWebApplicationContext(filterConfig.getServletContext());
		signaConfig = factory.getBean(SignaConfig.class);
		apiUserService = factory.getBean(ApiUserService.class);
	}
    @Override
	public void doFilter(ServletRequest servletrequest, ServletResponse servletresponse,
                         FilterChain chain) throws IOException, ServletException {
    }
	@Override
	public void destroy() {
		// TODO Auto-generated method stub
	}
}
