Question

spring boot2 RestTemplate 请求URL超时 RestTemplate配置代码如下 @Bean public RestTemplate restTemplate(RestTemplateBuilder builder) { HttpComponentsClientHttpRequestFactory httpRequestFactory = new HttpComponentsClientHttpRequestFactory(); httpRequestFactory.setConnectionRequestTimeout(30000); httpRequestFactory.setConnectTimeout(30000); httpRequestFactory.setReadTimeout(30000); return builder.requestFactory(() -> httpRequestFactory).build(); } 报错信息如下： org.springframework.web.client.ResourceAccessException: I/O error on GET request for "https://pro-api.coinmarketcap.com/v1/cryptocurrency/listings/latest": Connect to pro-api.coinmarketcap.com:443 [pro-api.coinmarketcap.com/13.35.121.116, pro-api.coinmarketcap.com/13.35.121.31, pro-api.coinmarketcap.com/13.35.121.107] failed: Read timed out; nested exception is org.apache.http.conn.ConnectTimeoutException: Connect to pro-api.coinmarketcap.com:443 [pro-api.coinmarketcap.com/13.35.121.116, pro-api.coinmarketcap.com/13.35.121.31, pro-api.coinmarketcap.com/13.35.121.107] failed: Read timed out at org.springframework.web.client.RestTemplate.doExecute(RestTemplate.java:696) at org.springframework.web.client.RestTemplate.exchange(RestTemplate.java:622) at com.chinawkb.monitor.service.impl.CoinMarketServiceImpl.getData(CoinMarketServiceImpl.java:58) at com.chinawkb.monitor.service.impl.CoinMarketServiceImpl.updateTokenInfos(CoinMarketServiceImpl.java:39) at com.chinawkb.monitor.EthereumMonitorApplication$Test.run(EthereumMonitorApplication.java:59) at org.springframework.boot.SpringApplication.callRunner(SpringApplication.java:792) at org.springframework.boot.SpringApplication.callRunners(SpringApplication.java:776) at org.springframework.boot.SpringApplication.run(SpringApplication.java:315) at org.springframework.boot.SpringApplication.run(SpringApplication.java:1242) at org.springframework.boot.SpringApplication.run(SpringApplication.java:1230) at com.chinawkb.monitor.EthereumMonitorApplication.main(EthereumMonitorApplication.java:38) Caused by: org.apache.http.conn.ConnectTimeoutException: Connect to pro-api.coinmarketcap.com:443 [pro-api.coinmarketcap.com/13.35.121.116, pro-api.coinmarketcap.com/13.35.121.31, pro-api.coinmarketcap.com/13.35.121.107] failed: Read timed out at org.apache.http.impl.conn.DefaultHttpClientConnectionOperator.connect(DefaultHttpClientConnectionOperator.java:151) at org.apache.http.impl.conn.PoolingHttpClientConnectionManager.connect(PoolingHttpClientConnectionManager.java:373) at org.apache.http.impl.execchain.MainClientExec.establishRoute(MainClientExec.java:394) at org.apache.http.impl.execchain.MainClientExec.execute(MainClientExec.java:237) at org.apache.http.impl.execchain.ProtocolExec.execute(ProtocolExec.java:185) at org.apache.http.impl.execchain.RetryExec.execute(RetryExec.java:89) at org.apache.http.impl.execchain.RedirectExec.execute(RedirectExec.java:110) at org.apache.http.impl.client.InternalHttpClient.doExecute(InternalHttpClient.java:185) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:83) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:56) at org.springframework.http.client.HttpComponentsClientHttpRequest.executeInternal(HttpComponentsClientHttpRequest.java:87) at org.springframework.http.client.AbstractBufferingClientHttpRequest.executeInternal(AbstractBufferingClientHttpRequest.java:48) at org.springframework.http.client.AbstractClientHttpRequest.execute(AbstractClientHttpRequest.java:53) at org.springframework.web.client.RestTemplate.doExecute(RestTemplate.java:687) ... 10 common frames omitted Caused by: java.net.SocketTimeoutException: Read timed out at java.net.SocketInputStream.socketRead0(Native Method) at java.net.SocketInputStream.socketRead(SocketInputStream.java:116) at java.net.SocketInputStream.read(SocketInputStream.java:171) at java.net.SocketInputStream.read(SocketInputStream.java:141) at sun.security.ssl.InputRecord.readFully(InputRecord.java:465) at sun.security.ssl.InputRecord.read(InputRecord.java:503) at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:983) at sun.security.ssl.SSLSocketImpl.performInitialHandshake(SSLSocketImpl.java:1385) at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1413) at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1397) at org.apache.http.conn.ssl.SSLConnectionSocketFactory.createLayeredSocket(SSLConnectionSocketFactory.java:396) at org.apache.http.conn.ssl.SSLConnectionSocketFactory.connectSocket(SSLConnectionSocketFactory.java:355) at org.apache.http.impl.conn.DefaultHttpClientConnectionOperator.connect(DefaultHttpClientConnectionOperator.java:142) ... 23 common frames omitted 已确认rest接口是可以访问的（同一台机器上的postMan可以正常运行） 有没有人遇到过，求教！！
