Spring boot 请求参数包含[]等特殊字符，导致无法接收问题

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: */@Configurationpublic class Config {    @Bean    public 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 ;    }}
