I am using Springboot with MongoDb and Elasticsearch for my project. When my Elasticsearch server is running then my Springboot application is working fine but when the Elasticsearch server is stopped, my Springboot application also fails to start. According to my project's requirements, our Springboot application should still be running even though the Elasticsearch server fails to start as the majority of our APIs are built on Springboot and MongoDb and only a few depend on Elasticsearch. Is there any way I can achieve this?
Elasticsearch configuration
@Bean(destroyMethod = "close")
public RestHighLevelClient client() {
RestHighLevelClient client = new RestHighLevelClient(
RestClient.builder(new HttpHost(hostname, port,scheme))
.setRequestConfigCallback(
new RestClientBuilder.RequestConfigCallback() {
@Override
public RequestConfig.Builder customizeRequestConfig(
RequestConfig.Builder requestConfigBuilder) {
return requestConfigBuilder
.setConnectTimeout(6000000)
.setSocketTimeout(6000000);
}
}));
return client;
}

CodePudding user response：
You can mark them beans with @Lazy so spring will not construct them on application startup. It will construct them when you use them runtime.
please see this documentation
