spring bean生命周期：http://www.cnblogs.com/zrtqsk/p/3735273.html html
session bean建立：java
/**
* Created by dongsilin on 2017/3/7.
* RestTemplate bean，生命周期为session
*/
@Configuration
public class RestTemplateBean {
private static final SimpleClientHttpRequestFactory requestFactory = new SimpleClientHttpRequestFactory();
private static final HttpMessageConverter httpMessageConverter = new StringHttpMessageConverter(Charset.forName("UTF-8"));
static {
requestFactory.setReadTimeout(1000 * 30); //30s
requestFactory.setConnectTimeout(1000 * 30); //30s
}
@Bean @Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS)
public RestTemplate initRestTemplate(){
RestTemplate restTemplate = new RestTemplate();
restTemplate.setRequestFactory(requestFactory);
restTemplate.getMessageConverters().set(1, httpMessageConverter);
return restTemplate;
}
}
session bean使用：spring
@Autowired private RestTemplate restTemplate;
