Exclude Spring Request HandlerInterceptor by Path-Pattern
提问by Ron Zoosk
I know we can map different url to different interceptor, or we can map multiple url to single interceptor too. I am just curious to know if we also have exclude option. for example if I have 50 url mapping in application and except 1 mapping I want to call interceptor for all so rather than writing configuration for 49 mapping can I just mention * and one exclude to the 50th url?
我知道我们可以将不同的 url 映射到不同的拦截器，或者我们也可以将多个 url 映射到单个拦截器。我只是想知道我们是否也有排除选项。例如，如果我在应用程序中有 50 个 url 映射，除了 1 个映射，我想为所有对象调用拦截器，而不是为 49 个映射编写配置，我可以只提到 * 和第 50 个 url 的一个排除吗？

HandlerInterceptors can be applied or excluded to (multiple) specific url's or url-patterns.
HandlerInterceptors 可以应用于或排除（多个）特定的 url 或 url-patterns。
See the MVC Interceptor Configuration.
请参阅MVC 拦截器配置。
Here are the examples from the documentation
以下是文档中的示例
@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new LocaleInterceptor());
registry.addInterceptor(new ThemeInterceptor()).addPathPatterns("/**").excludePathPatterns("/admin/**");
// multiple urls (same is possible for `exludePathPatterns`)
registry.addInterceptor(new SecurityInterceptor()).addPathPatterns("/secure/*", "/admin/**", "/profile/**");
}
}
or using XML config
或使用 XML 配置
<mvc:interceptors>
<bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor"/>
<mvc:interceptor>
<mvc:mapping path="/**"/>
<mvc:exclude-mapping path="/admin/**"/>
<bean class="org.springframework.web.servlet.theme.ThemeChangeInterceptor"/>
</mvc:interceptor>
<mvc:interceptor>
<!-- intercept multiple urls -->
<mvc:mapping path="/secure/*"/>
<mvc:mapping path="/admin/**"/>
<mvc:mapping path="/profile/**"/>
<bean class="org.example.SecurityInterceptor"/>
</mvc:interceptor>
</mvc:interceptors>

I think in spring-boot 2.0 version, this have changed a lot right now. Below is the implementation you can easily add and configure the path pattern.
我认为在 spring-boot 2.0 版本中，这现在已经改变了很多。下面是您可以轻松添加和配置路径模式的实现。
@Component
public class ServiceRequestAppConfig implements WebMvcConfigurer {
@Autowired
ServiceRequestInterceptor sri;
@Override
public void addInterceptors(InterceptorRegistry registry) {
String pathPattern = "/admin/**";
registry.addInterceptor(sri).excludePathPatterns(pathPattern);
}
}
@Component
public class ServiceRequestInterceptor extends HandlerInterceptorAdapter {
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) {
// Your logic
return true;
}
@Override
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, @Nullable Exception ex){
// Some useful techniques
}
}
