springboot设置接口超时

springboot　设置接口超时

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

设置配置HttpComponentsClientHttpRequestFactory中的RequestConfig属性

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;
}

@Bean
public 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
