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;

@Configuration
public 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 ;
    }
