本專案為前後端分離，介面採用springboot2+mybatis方式，前端header攜帶authorization引數請求介面，有些介面不需要攜帶authorization，本人初搞java，在研究了老半天后如下的方式解決了我的問題，在攔截器裡拿到了我要的authorization，相關配置程式碼如下：

一、建立攔截器配置

@Configuration
public class InterceptorConfig implements WebMvcConfigurer {

一開始拿不到authorization是因為在攔截器配置裡 少了下面這段話，最初是registry.addInterceptor(new new AuthorizationInterceptor())這種寫法，怎麼都拿不到authorization;

//讓bean提前載入
@Bean
public HandlerInterceptor getInterceptor(){
    return new AuthorizationInterceptor();
}

@Override
public void addInterceptors(InterceptorRegistry registry) {
    //註冊攔截器
    InterceptorRegistration registration = registry.addInterceptor(getInterceptor());
    registration.addPathPatterns("/**");
    registration.excludePathPatterns(
            "/api/Base_User/UserLogin",
            "/api/Base_User/GetCode",
            "/api/Base_PT_Type/GetDataList",
            "/api/Base_User/UserInfoByToken",
            "/**/*.html",
            "/**/*.js",
            "/**/*.css",
            "/**/*.woff",
            "/**/*.ttf"
    );
  }
}
 

二、攔截器

public class AuthorizationInterceptor implements HandlerInterceptor {
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {

    if (HttpMethod.OPTIONS.toString().equals(request.getMethod())){
        response.setStatus(HttpServletResponse.SC_OK);
        return true;
    }

    String authorization = request.getHeader("authorization");
    if (StringHelper.isEmpty(authorization)){
        return false;
    }
    String userid= TokenUtils.verify(authorization.replace("Bearer ",""));
    if (StringHelper.isEmpty(userid)){
        ResponseModel dataobj=new ResponseModel(0,false,"token無效");

        return false;
    }
    return true;
}

@Override
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, @Nullable ModelAndView modelAndView) throws Exception {
}
 

}
