springboot 拦截器解决authorization为null

本项目为前后端分离，接口采用springboot2+mybatis方式，前端header携带authorization参数请求接口，有些接口不需要携带authorization，本人初搞java，在研究了老半天后如下的方式解决了我的问题，在拦截器里拿到了我要的authorization，相关配置代码如下：

一、创建拦截器配置

原代码如下，这种拿不到authorization：

public class InterceptorConfig implements WebMvcConfigurer {
@Override
public void addInterceptors(InterceptorRegistry registry) {
//注册拦截器
## 新旧写法区别就在这里
InterceptorRegistration registration = registry.addInterceptor(new AuthorizationInterceptor());

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"
);
}
}

新代码 增加getInterceptor()

@Configuration
public class InterceptorConfig implements WebMvcConfigurer {
//让bean提前加载
@Bean
public HandlerInterceptor getInterceptor(){
return new AuthorizationInterceptor();
}

@Override
public void addInterceptors(InterceptorRegistry registry) {
//注册拦截器
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、拦截器

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无效");

return false;
}
return true;
}

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