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; import org.apache.http.conn.ssl.NoopHostnameVerifier; import org.apache.http.conn.ssl.SSLConnectionSocketFactory; import org.apache.http.impl.client.CloseableHttpClient; import org.apache.http.impl.client.HttpClients; import org.apache.http.impl.conn.PoolingHttpClientConnectionManager; import org.apache.http.ssl.SSLContextBuilder; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.http.client.ClientHttpRequestInterceptor; import org.springframework.http.client.HttpComponentsClientHttpRequestFactory; import org.springframework.http.converter.StringHttpMessageConverter; import org.springframework.web.client.RestTemplate; import java.nio.charset.StandardCharsets; import java.security.KeyManagementException; import java.security.KeyStoreException; import java.security.NoSuchAlgorithmException; import java.security.cert.X509Certificate; import java.util.ArrayList; import java.util.List; @Configuration public class RestConfig { @Bean public RestTemplate buildRestTemplate(List<RequestHeaderInterceptor> interceptors) throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException { HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory(); // factory.setConnectionRequestTimeout(requestTimeout); // factory.setConnectTimeout(connectTimeout); // factory.setReadTimeout(readTimeout); // https SSLContextBuilder builder = new SSLContextBuilder(); builder.loadTrustMaterial(null, (X509Certificate[] x509Certificates, String s) -> true); SSLConnectionSocketFactory socketFactory = new SSLConnectionSocketFactory(builder.build(), new String[]{"SSLv2Hello", "SSLv3", "TLSv1", "TLSv1.1", "TLSv1.2"}, null, NoopHostnameVerifier.INSTANCE); Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create() .register("http", new PlainConnectionSocketFactory()) .register("https", socketFactory).build(); PoolingHttpClientConnectionManager phccm = new PoolingHttpClientConnectionManager(registry); phccm.setMaxTotal(200); CloseableHttpClient httpClient = HttpClients.custom().setSSLSocketFactory(socketFactory).setConnectionManager(phccm).setConnectionManagerShared(true).build(); factory.setHttpClient(httpClient); RestTemplate restTemplate = new RestTemplate(factory); List<ClientHttpRequestInterceptor> clientInterceptorList = new ArrayList<>(); for (RequestHeaderInterceptor i : interceptors) { ClientHttpRequestInterceptor interceptor = i; clientInterceptorList.add(interceptor); } restTemplate.setInterceptors(clientInterceptorList); restTemplate.getMessageConverters().set(1, new StringHttpMessageConverter(StandardCharsets.UTF_8)); return restTemplate; } }希望能帮到同样遇到该问题的同学
