Let me show the code.

@Configuration
public class RestTemplateConfig 
 @Bean
 public RestTemplate restTemplate(ClientHttpRequestFactory factory) 
 return new RestTemplate(factory);
 
 @Bean
 public ClientHttpRequestFactory simpleClientHttpRequestFactory() 
 SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory();
 factory.setReadTimeout(PublicConfigRpt.REST_TEMPALTE_READ_TIMEOUT);
 factory.setConnectTimeout(PublicConfigRpt.REST_TEMPLATE_CONNECT_TIMEOUT);
 return factory;
 

PublicConfigRpt.REST_TEMPALTE_READ_TIMEOUT is defined as below.

@Configuration
public class PublicConfigRpt 

 public static Integer REST_TEMPALTE_READ_TIMEOUT;
 public static Integer REST_TEMPLATE_CONNECT_TIMEOUT;

 @Value("$rest_template_read_timeout")
 public void setRestTempalteReadTimeout(Integer restTempalteReadTimeout) 
 REST_TEMPALTE_READ_TIMEOUT = restTempalteReadTimeout;
 

 @Value("$rest_template_connect_timeout")
 public void setRestTemplateConnectTimeout(Integer restTemplateConnectTimeout) 
 REST_TEMPLATE_CONNECT_TIMEOUT = restTemplateConnectTimeout;
 

The timeout parameter is read from property file and set in SimpleClientHttpRequestFactory.

It is OK when started from local Intellij idea. But when it deployed to k8s, it throws exception.

2019/03/07 16:50:34.964 | INFO | Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'simpleClientHttpRequestFactory' defined in class path resource [cn/homersatellite/dd/jd/report/config/RestTemplateConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.http.client.ClientHttpRequestFactory]: Factory method 'simpleClientHttpRequestFactory' threw exception; nested exception is java.lang.NullPointerException

The PublicConfigRpt.REST_TEMPALTE_READ_TIMEOUT is null when simpleClientHttpRequestFactory is invoked, then it throws null exception. Anyone can tell me how to handle this? Thanks.
