springBoot拦截不到TRACE类型请求

Spring Boot本身并不直接限制对TRACE类型的HTTP请求的拦截,但是默认情况下,它可能会忽略这类低优先级的请求。因为TRACE请求主要用于获取交互过程的详细信息,并不是常规业务请求,所以很多框架会选择不处理它们,包括Spring Boot。
如果你想要拦截到TRACE请求,可以采取以下步骤:
1. **配置全局拦截器**:你可以创建一个全局异常处理器或WebMvcConfigurer接口的实现类,然后注册一个拦截所有HTTP请求的`RequestMappingHandlerInterceptor`。确保在这个拦截器中检查并处理`RequestMethod.TRACE`。
```java
@Configuration
public class WebConfig implements WebMvcConfigurer {
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new TraceRequestInterceptor())
.addPathPatterns("/**");
}
private static class TraceRequestInterceptor implements HandlerInterceptorAdapter {
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
if (request.getMethod().equals(HttpMethod.TRACE)) {
// 对TRACE请求做特殊处理
System.out.println("Received TRACE request for " + request.getRequestURI());
}
return true;
}
}
}
```
2. **自定义Filter**:如果想在Servlet层拦截,可以创建一个过滤器并在其中处理TRACE请求。
```java
@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class TraceFilter implements Filter {
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
HttpServletRequest httpRequest = (HttpServletRequest) request;
if (httpRequest.getMethod().equals(HttpMethod.TRACE)) {
// 处理TRACE请求...
} else {
chain.doFilter(request, response);
}
}
}
```
