第一步,约定好传参编码格式

不管是运用httpclient，还是原生http，都要设置传参的编码，为了统一，这儿全部设置为utf-8

第二步，修正application.properties文件

添加如下配置信息：

spring.http.encoding.force=true

spring.http.encoding.charset=UTF-8

spring.http.encoding.enabled=true

server.tomcat.uri-encoding=UTF-8

package com.springboot.bootdemo01;

import org.springframework.boot.autoconfigure.web.WebMvcAutoConfiguration;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.http.converter.HttpMessageConverter;

import org.springframework.http.converter.StringHttpMessageConverter;

import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

import java.nio.charset.Charset;

import java.util.List;
