Spring Boot 中使用 Filter 与 HandlerInterceptor 路径匹配差别

环境说明

• spring boot 1.5.9
• jdk8

问题概述

在spring boot中使用Filter和HandlerIntercepter中对于相同路径匹配写法有差别,如路径/api/v1/service1,在Filter中可以使用/api/*,但在HandlerIntercepter注册时需要写成/api/**,以下为相关具体说明

1. Filter

在spring boot中自定义Filter(该Filter继承自org.springframework.web.filter.OncePerRequestFilter)在注册匹配路径时,对于/api/v1/service1做路径映射时,需要使用/api/*匹配

完整代码如下:

    @Bean
    public FilterRegistrationBean filterRegistrationBean() {
        FilterRegistrationBean registrationBean = new FilterRegistrationBean();
        //初始化自定义RequestFilter
        ApiRequestFilter apiRequestFilter = new ApiRequestFilter(apiConfigService);
        registrationBean.setFilter(apiRequestFilter);
        List urlPatterns = new ArrayList<>();
        //设置映射路径
        urlPatterns.add("/api/*");
        registrationBean.setUrlPatterns(urlPatterns);
        return registrationBean;
    }

2. HandlerInterceptor

在spring boot中自定义HandlerInterceptor(该HandlerInterceptor继承自org.springframework.web.servlet.handler.HandlerInterceptorAdapter)在注册匹配路径时,对于/api/v1/service1做路径映射时,需要使用/api/**匹配

完整代码如下:

@SpringBootApplication
@RestController
public class DemoApplication extends WebMvcConfigurerAdapter {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        // 添加拦截器
        registry.addInterceptor(new ApiInterceptor()).addPathPatterns("/api/**");
    }
}
