进行如下修改即可。
首先是 WebMvcConfiguration：
@Configuration
public class WebMvcConfiguration extends WebMvcConfigurerAdapter {
@Bean
public AuthenticationInterceptor authenticationInterceptor() {
return new AuthenticationInterceptor();
}
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(authenticationInterceptor()).addPathPatterns("/**");
}
}然后需要使 springboot 扫描到当前 Interceptor，也就是在类上加上 @Component 注释。
@Component
public class AuthenticationInterceptor implements HandlerInterceptor {
@Autowired
private UserService userService;
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object o) throws Exception {
User user = userService.getById(id);
}
@Override
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object o, ModelAndView modelAndView) throws Exception {
}
@Override
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object o, Exception e) throws Exception {
}
}SpringBoot 拦截器中无法使用 @Autowired 注入 Service
