按路径模式排除Spring Request HandlerInterceptor

标签: spring interceptor

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,我想为所有人调用拦截器,而不是为49映射编写配置,我可以提及*和一个排除到第50个URL吗?

HandlerInterceptor可以应用或排除到(多个)特定网址或网址模式。

请参阅MVC Interceptor Configuration

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/**");
    }
}

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>

我认为在spring-boot 2.0版本中,这已经发生了很大变化。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
    }

}

就我而言:

/ api / v1 /用户管理器服务/租户/添加

PathPattern配置不正确:

 @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new RequestInterceptor())
                .addPathPatterns("/**")
                .excludePathPatterns("/tenants/**");
    }

我不见了:

/ **

在实际路径之前。

更正后,它可以按预期工作:

@Override
public void addInterceptors(InterceptorRegistry registry) {
    registry.addInterceptor(new RequestInterceptor())
            .addPathPatterns("/**")
            .excludePathPatterns("/**/tenants/**");
}
