1、webconfig中引用要注解引用
之前是直接new了一个
@Configuration
public class WxWebMvcConfiguration implements WebMvcConfigurer {
@Autowired
private LoginUserHandlerMethodArgumentResolver loginUserHandlerMethodArgumentResolver;
@Override
public void addArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers) {
argumentResolvers.add(loginUserHandlerMethodArgumentResolver);
}
}
2、HandlerMethodArgumentResolver 中加Service注解
