In-depth source code analysis, how does Spring solve circular dependencies?

1. Basic knowledge 1.1 What is circular dependency? There are direct or indirect dependencies between one or more objects. This dependency constitutes a circular call in the following three ways. Let’s look at a simple Demo, targeting “Scenario 2”. @Service public class Louzai1 { @Autowired private Louzai2 louzai2; public void test1() { } } @Service […]

[Docker] Docker Compose service dependencies and health checks

docker compose environment variables To increase security, add redis password verification in the previous python example, and the password is obtained from the environment variable: from flask import Flask from redis import StrictRedis import os import socket app = Flask(__name__) redis = StrictRedis(host=os.environ.get(‘REDIS_HOST’, ‘127.0.0.1’), port=6379, password=os.environ.get(‘REDIS_PASS’)) @app.route(‘/’) def hello(): redis.incr(‘hits’) return f”Hello Container World!

SpringBoot integrates ElasticSearch (different dependencies, business code and JPA methods are also different)

Framework: springboot + gradle 1. Introduce dependencies implementation(“org.elasticsearch:elasticsearch:7.6.1”) implementation(“org.elasticsearch.client:elasticsearch-rest-high-level-client:7.6.1”) 2. Configure application elasticsearch: username: elastic password: elastic uris: localhost:9200 3. Configuration file @Configuration @RequiredArgsConstructor public class ElasticsearchConfig{ public static ObjectMapper objectMapper = new ObjectMapper(); @Bean(“restHighLevelClient”) public RestHighLevelClient elasticsearchClient(ElasticsearchProperties elasticsearchProperties){ final CredentialsProvider credentialsProvider = new BasicCredentialsProvider(); credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(elasticsearchProperties.getUsername(), elasticsearchProperties.getPassword())); RestClientBuilder restClientBuilder = RestClient.builder(HttpHost.create(elasticsearchProperties.getUris().get(0))) .setHttpClientConfigCallback(httpAsyncClientBuilder -> […]
