总结一下项目：代理和信托。

代理涵盖帮助投资机构/投资者买卖证券，收益归投资者。

信托涵盖财富管理，收益归约定的受益人。

RestClient Official Document

The RestClient is a synchronous HTTP client that offers a modern, fluent API. It offers an abstraction over HTTP libraries that allows for convenient conversion from a Java object to an HTTP request, and the creation of objects from an HTTP response.

Lets see how it is designed.

Docker Compose simplifies the management of multi-container applications by defining services, networks, and volumes in a single YAML file.

with a single command, we can create and start all the services from yaml file.

let’s see how we use docker compose in Spring Boot. Github Demo / Docker Compose Support in Spring Boot

Backoff is a strategy for dealing with failures, conflicts, or resource competition.

The core logic is: when an operation fails or encounters a limitation, it will pause for a period of time before trying again, and the retry interval is usually adjusted dynamically to avoid increasing system pressure or conflicts.

let’s see how spring-framework implement it.

in Spring-Framework 7.0, Spring team redesigned a minimal core retry feature in spring-core. inspired by the Spring Retry project.

currently only with 3 classes & 4 interfaces.

let’s deep into it.

Introduce minimal retry functionality as a core framework feature

Introduce @Retryable AOP support (based on core.retry and Reactor retry functionality)

when I try to read the spring-integration code, I find it is essential to know spring-messaging first. some concepts are same like message channel, pollable / subscribable channel, asynchronious, integration, etc.

spring-messaging is a sub-module under spring-framework. it highly abstracts the components when two systems needs to communicate via messages.
