解决中文乱码

一、在返回中的头部信息中指定字符集为UTF-8

 response.setCharacterEncoding("utf-8");

二、在API上指定produces

@RequestMapping(value = "/hello", produces = "application/json; charset=UTF-8")

三、全局配置字符编码

package com.reachauto.hkr.common.config;

import com.fasterxml.jackson.databind.ObjectMapper;
import com.reachauto.hkr.common.feign.FeignInterceptor;
import feign.RequestInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.http.converter.ResourceHttpMessageConverter;
import org.springframework.http.converter.StringHttpMessageConverter;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

import java.util.List;
