１、配置文件
application.properties中加了，意思是设置超时时间为20000ms即20s，
spring.mvc.async.request-timeout=20000
2、config配置类
public class WebMvcConfig extends WebMvcConfigurerAdapter {
@Override
public void configureAsyncSupport(final AsyncSupportConfigurer configurer) {
configurer.setDefaultTimeout(20000);
configurer.registerCallableInterceptors(timeoutInterceptor());
}
@Bean
public TimeoutCallableProcessingInterceptor timeoutInterceptor() {
return new TimeoutCallableProcessingInterceptor();
}
}3、RestTemplate超时
import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;
import org.springframework.web.client.RestTemplate;
@Slf4j
@Configuration
public class RestTemplateConfig {
@Bean
@ConfigurationProperties(prefix = "rest.connection")
public HttpComponentsClientHttpRequestFactory httpRequestFactory() {
return new HttpComponentsClientHttpRequestFactory();
}
@Bean
public RestTemplate customRestTemplate(){
return new RestTemplate(httpRequestFactory());
}
}也可以：
@Beanpublic SimpleClientHttpRequestFactory httpRequestFactory() {
SimpleClientHttpRequestFactory requestFactory = new SimpleClientHttpRequestFactory();
requestFactory.setConnectTimeout(1000);
requestFactory.setReadTimeout(1000);
return requestFactory;
}
@Beanpublic RestTemplate customRestTemplate(){
return new RestTemplate(httpRequestFactory());
}application.properties:
#restTemplate配置# 连接不共用的时候，等待连接超时。
rest.connection.connectionRequestTimeout=30000# 建立连接超时
rest.connection.connectTimeout=30000# 建立连接成功后 从服务器读取超时
rest.connection.readTimeout=30000或者
#restTemplate配置
rest.connection.connection-request-timeout=30000
rest.connection.connect-timeout=30000
rest.connection.read-timeout=30000推荐文章：
