正常的參數，在后臺都是可以接收的，但是有時候會遇到一些比較奇怪的參數，帶有特殊的字符例如

特殊參數傳遞

還有的參數里面會有大括號之類的
{}[]類似于這樣的參數，后臺不處理一般是接收不到的；
處理方式如下

@SpringBootApplication
@EnableScheduling
@EnableFeignClients
public class ZhAlarmApplication {
    public static void main(String[] args) {
        ApplicationContext context = SpringApplication.run(ZhAlarmApplication.class, args);
        SpringContextUtil.setApplicationContext(context);
    }

    @Bean
    public ConfigurableServletWebServerFactory webServerFactory() {
        TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();
        factory.addConnectorCustomizers((TomcatConnectorCustomizer) connector -> connector.setProperty("relaxedQueryChars", "|{}[]\\"));
        return factory;
    }
}

如圖在啟動類中加入下面：

@Bean
    public ConfigurableServletWebServerFactory webServerFactory() {
        TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();
        factory.addConnectorCustomizers((TomcatConnectorCustomizer) connector -> connector.setProperty("relaxedQueryChars", "|{}[]\\"));
        return factory;
    }
