spring boot 集成 restTemplate 调用第三方接口中文乱码问题

最近使用restTemplate调第三方接口返回中文出现乱码
双方均已约定使用utf-8编码格式，但返回接口中文乱码，在排查过程中发现restTemplate默认的是ISO-8859-1编码，因此需要将编码格式改为utf-8，修改如下 ：

添加：

restTemplate.getMessageConverters().set(1, new StringHttpMessageConverter(StandardCharsets.UTF_8));

package com.igen.sorting.icbc.config;import org.apache.http.config.Registry;
import org.apache.http.config.RegistryBuilder;
import org.apache.http.conn.socket.ConnectionSocketFactory;
import org.apache.http.conn.socket.PlainConnectionSocketFactory;

}

希望能帮到同样遇到该问题的同学
