Resttemplate请求中文乱码

1 概述

解决RestTemplate请求中文乱码问题。

如果是StringHttpMessageConverter,则修改器默认字符集:ISO-8859-1为utf-8,对于postForObject 底层均采用了MappingJackson2HttpMessageConverter来处理请求。

对于String格式提交数据时，底层其实采用的是StringHttpMessageConverter来处理请求。

1.1 RestTemplateUtil

package com.kikop.localribbonclient.util;

import org.springframework.http.converter.HttpMessageConverter;

import org.springframework.http.converter.StringHttpMessageConverter;

import org.springframework.web.client.RestTemplate;

import java.nio.charset.Charset;

import java.util.List;

*/

public class RestTemplateUtil {

/**

 * 获取restTemplate实例

 *

 * @param charset utf-8

 * @return

 */

public static RestTemplate getInstance(String charset) {

    // 如果是StringHttpMessageConverter,则修改器默认字符集:ISO-8859-1为utf-8

    // postForObject 底层均采用了MappingJackson2HttpMessageConverter来处理请求

    // String格式提交数据时，底层其实采用的是StringHttpMessageConverter来处理请求

    RestTemplate restTemplate = new RestTemplate();

    List<HttpMessageConverter<?>> list = restTemplate.getMessageConverters();

    for (HttpMessageConverter<?> httpMessageConverter : list) {

        if (httpMessageConverter instanceof StringHttpMessageConverter) {

            ((StringHttpMessageConverter) httpMessageConverter).setDefaultCharset(Charset.forName(charset));

            break;

        }

    }

    return restTemplate;

}

}

1.2使用

package com.kikop.localribbonclient.controller;

import com.kikop.localribbonclient.util.RestTemplateUtil;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.cloud.client.ServiceInstance;

import org.springframework.cloud.client.loadbalancer.LoadBalancerClient;

import org.springframework.web.bind.annotation.GetMapping;

import org.springframework.web.bind.annotation.RestController;

import org.springframework.web.client.RestTemplate;

/**

• @author kikop

• @version 1.0

• @project Name: myribboninaction

• @file Name: RibbonController

• @desc 功能描述

• @date 2020/2/9

• @time 11:02

*/

@RestController

public class RibbonController {

@Autowired

private LoadBalancerClient loadBalancer;

@GetMapping("/testRibbon")

public String testRibbon() {

    ServiceInstance instance = loadBalancer.choose("stores");

    return instance.getHost() + ":" + instance.getPort();

}

@GetMapping("/testReqDomain")

public String testReqDomain() {

    ServiceInstance instance = loadBalancer.choose("stores");

    String reqServerUrl = String.format("http://%s:%d", instance.getHost(), instance.getPort());

    System.out.println(reqServerUrl);

    RestTemplate restTemplate = RestTemplateUtil.getInstance("utf-8");

    return restTemplate.getForObject(reqServerUrl, String.class);

}

}
