Question

基于某些业务逻辑，我需要在请求到达控制器之前向请求添加查询参数。为了实现这一点，我使用了HandlerInterceptorAdapter来拦截请求。我有一个公用的lib，在其中定义了一个拦截器，从属项目具有控制器。拦截器正在注册，但是当我调用任何api调用时都不会被调用。

通用lib中的拦截器



@Component
public class RequestInterceptor extends HandlerInterceptorAdapter {

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, java.lang.Object handler)
            throws ServletException, IOException {
         request.setAttribute("id", "123"); // this would be populated based on logic

        return true;
    }
}

依赖性


@Configuration
public class Resolver implements WebMvcConfigurer {

@Autowired
RequestInterceptor interceptor;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(interceptor);
    }

}

您不必注释RequestInterceptor。请从RequestInterceptor类的@Autowired中删除@Component注释，并从Resolver类中删除此依赖性的public class RequestInterceptor extends HandlerInterceptorAdapter { @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, java.lang.Object handler) throws ServletException, IOException { request.setAttribute("id", "123"); // this would be populated based on logic return true; } } @Configuration @EnableWebMvc public class Resolver implements WebMvcConfigurer { @Override public void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(new RequestInterceptor()); } }注释。代替注入，请通过默认构造函数实例化它。

拦截器没有被调用
