filter与interceptor的区别
filter 作用于 servlet，而 interceptor 作用于 spring。
可以看到 filter 作用在 DispatcherServlet 之前，而 interceptor 作用在之后。
filter
Filters are part of the webserver and not the Spring framework. For incoming requests, we can use filters to manipulate and even block requests from reaching any servlet. Vice versa, we can also block responses from reaching the client.
fitler 的 @Order 注解数字越小越先执行。 -2 < -1 < 0 < 1 < 2。
@Slf4j
@Component
@Order(-1)
public class LogFilter implements Filter {
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
log.info("in filter before chain.doFilter");
chain.doFilter(request, response);
log.info("in filter after chain.doFilter");
}
}
@Slf4j
@Component
@Order(-2)
public class LogFilter2 implements Filter {
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
log.info("in filter2 before chain.doFilter");
chain.doFilter(request, response);
log.info("in filter2 after chain.doFilter");
}
}
输出如下：
in filter2 before chain.doFilter
in filter before chain.doFilter
in filter after chain.doFilter
in filter2 after chain.doFilter
interceptor
跟在 spring 中的 add 顺序有关。
@Configuration
public class SpringConfiguration implements WebMvcConfigurer {
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new LogInterceptor());
registry.addInterceptor(new LogInterceptor2());
WebMvcConfigurer.super.addInterceptors(registry);
}
}
输出如下：
in interceptor preHandle
in interceptor2 preHandle
in interceptor2 postHandle
in interceptor postHandle
in interceptor2 afterCompletion
in interceptor afterCompletion
如上图，如果preHandle返回 false，那么 Controller 无法执行了，直接执行afterCompletion。
404
如果访问不存在的 uri 会发生什么？
in filter2 before chain.doFilter
in filter before chain.doFilter
in interceptor preHandle, url: http://localhost:8080/notfound
in interceptor2 preHandle
in interceptor2 postHandle
in interceptor postHandle, url: http://localhost:8080/notfound
in interceptor2 afterCompletion
in interceptor afterCompletion, url: http://localhost:8080/notfound
in filter after chain.doFilter
in filter2 after chain.doFilter
in interceptor preHandle, url: http://localhost:8080/error
in interceptor2 preHandle
in interceptor2 postHandle
in interceptor postHandle, url: http://localhost:8080/error
in interceptor2 afterCompletion
in interceptor afterCompletion, url: http://localhost:8080/error
可以看到 filter 和 interceptor 会完全走完，最后被重定向到了/error。
而重定向到/error 不会再走 filter，因为/error 没有经过 tomcat，只是在 spring 中流转。
在controller中抛出异常
@RequestMapping("/exception")
public void exception() {
log.info("throw biz exception");
throw new RuntimeException("biz exception");
}
增加一个异常 handler
@Component
@Slf4j
public class MyResponseStatusExceptionResolver extends AbstractHandlerExceptionResolver {
@Override
protected ModelAndView doResolveException(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) {
try {
// modify status code
log.info("in MyResponseStatusExceptionResolver, url: {}", request.getRequestURL());
response.sendError(600, "biz error");
} catch (Exception e) {
log.error("error in MyResponseStatusExceptionResolver.", e);
}
return new ModelAndView();
}
}

可以看到 interceptor 的 postHandle 没有执行。虽然增加了AbstractHandlerExceptionResolver也是会重定向到/error。
注意：Controller 抛出的异常被AbstractHandlerExceptionResolver处理了。但是如果访问不存在 uri(404)不会被AbstractHandlerExceptionResolver处理。
如果在filter中抛出了异常
在chain.doFilter之前抛异常

可以看到后面的 controller、 interceptor、doFilter 之后的日志都没有打印。
在chain.doFilter之后抛异常
@Slf4j
@Component

public class LogFilter implements Filter {
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

chain.doFilter(request, response);
if (true) {
throw new RuntimeException("after doFilter throw exception in filter");
}
log.info("in filter after chain.doFilter");
}
}
正常请求
请求正常响应的 uri，竟然又来一次重定向，不符合预期。需要看源码了。
