spring boot 加入拦截器后swagger不能访问问题

spring boot 加入拦截器后swagger不能访问问题

未加入拦截器时，swagger可以正常访问接口信息，但是加入拦截器之后swagger就不能访问了

原因分析

不能访问的原因的swagger的内置接口被拦截器拦下来了

图片中可以看到swagger的所有请求的url信息，只要把他们加到拦截器的排除列表中即可

package com.trimps928.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

/**

 * @version 2018-06-26
 * 拦截器配置
 **/
@Configuration
public class MyWebAppConfig extends WebMvcConfigurationSupport {

    @Bean
    LoginInterceptor localInterceptor() {
        return new LoginInterceptor();
    }

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(localInterceptor())
                .addPathPatterns("/**")
                .excludePathPatterns("/user/login")
                .excludePathPatterns("/swagger-resources/**", "/webjars/**", "/v2/**", "/swagger-ui.html/**");
    }

    @Override
    protected void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("swagger-ui.html")
                .addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars/**")
                .addResourceLocations("classpath:/META-INF/resources/webjars/");
    }
}

网上找的资料中大部分只说添加这个
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(localInterceptor())
.addPathPatterns("/**")
.excludePathPatterns("/user/login")
.excludePathPatterns("/swagger-resources/**", "/webjars/**", "/v2/**", "/swagger-ui.html/**");
}
或者只添加
@Override
protected void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("swagger-ui.html")
.addResourceLocations("classpath:/META-INF/resources/");
registry.addResourceHandler("/webjars/**")
.addResourceLocations("classpath:/META-INF/resources/webjars/");
}
无数次的实验发现这两个方法都需要重写，只加任何一个都无法生效
