springboot如何处理矩阵参数类型的url

矩阵参数类型的url如何处理

首先要开启这个功能

在webconfig类中创建Webconfigurer类 并且设置 urlPathHelper类中的removeSemicolonContent 为false

 @Bean

    public WebMvcConfigurer webMvcConfigurer(){

        return  new WebMvcConfigurer() {

            @Override

            public void configurePathMatch(PathMatchConfigurer configurer) {

                UrlPathHelper urlPathHelper = new UrlPathHelper();

                urlPathHelper.setRemoveSemicolonContent(false);

                configurer.setUrlPathHelper(urlPathHelper);

            }

        };

    }

下面测试类

  /**

     * url: http://localhost:8080/cars/sell;low=34;brand=byd,audi,yd

     * @param low

     * @param brand

     * @param PATH

     * @return map

     */

    @GetMapping("/cars/{path}")

    public Map carsSell(@MatrixVariable("low") Integer low,

                        @MatrixVariable("brand") List<String> brand,

                        @PathVariable("path")String PATH){

        Map<String,Object> map = new HashMap<>();

        map.put("low",low);

        map.put("brand",brand);

        map.put("path",PATH);

        return map;

    }

结果图如下：
