前言

Spring boot 请求参数包含[]等特殊字符，导致无法接收问题

对字符进行转义

中括号[] 必须用%5B%5D转义，否则tomcat无法解析，回抛出不合法字符异常，不会进入控制器

修改tomcat 配置

package cn.com.cosmagn.wms.config;import org.springframework.boot.web.embedded.tomcat.TomcatConnectorCustomizer;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;/*** @Author: hrd* @CreateTime: 2024/3/8 13:56* @Description:*/
@Configuration
public class Config {@Beanpublic TomcatServletWebServerFactory tomcatServletWebServerFactory (){// 修改内置的 tomcat 容器配置TomcatServletWebServerFactory tomcatServlet = new TomcatServletWebServerFactory();tomcatServlet .addConnectorCustomizers((TomcatConnectorCustomizer) connector -> connector.setProperty("relaxedQueryChars", "[]"));return tomcatServlet ;}
