SOFABoot dependency management

Before using SOFA middleware, we need to introduce SOFABoot dependency management.

<parent>
    <groupId>com.alipay.sofa</groupId>
    <artifactId>sofaboot-dependencies</artifactId>
    <version>${sofa.boot.version}</version>
</parent>

Middleware introduced SOFA

SOFABoot using a series of suffixes to -sofa-boot-starter to mark a middleware component, if you want to use a middleware, can be added directly to the corresponding dependence.

<dependency>
    <groupId>com.alipay.sofa</groupId>
    <artifactId>rpc-sofa-boot-starter</artifactId>
</dependency>

Middleware	starter
SOFARPC	rpc-sofa-boot-starter
SOFATracer	tracer-sofa-boot-starter
SOFALookout	lookout-sofa-boot-starter

Expanding component introduced SOFABoot

Spring Boot SOFABoot based health screening, isolation module, isolation class scalability.

Extended Components	starter
health examination	healthcheck-sofa-boot-starter
Modular isolation	isle-sofa-boot-starter
Class isolation	sofa-ark-springboot-starter
Extended Test	test-sofa-boot-starter

SOFA introduced middleware plug-ark

SOFABoot isolation assembly provides a class SOFAArk, SOFAArk container means, a user may rely on conflict constituents packaged into packets ark plug. Runtime, ark plug-in uses a separate class loader, can and plug-ins and other business depends ark isolation, solve the problem of class conflict.

Providing SOFARPC SOFABoot official SOFATracer the ark and plug, for example into plug-in dependencies SOFARPC ark Alternatively SOFARPC starter in the application, and to isolate the application and SOFARPC indirectly dependent.

Ark plug	plugin
SOFARPC	rpc-sofa-boot-plugin
SOFATracer	tracer-sofa-boot-plugin

Namespace introduced SOFABoot

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:sofa="http://sofastack.io/schema/sofaboot"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
            http://sofastack.io/schema/sofaboot   http://sofastack.io/schema/sofaboot.xsd"
       default-autowire="byName">
</beans>

Introducing SOFABoot Infra-dependent

To view SOFABoot directly through the browser version information SOFA middleware, only need to add the following content in Maven dependencies can:

<dependency>
    <groupId>com.alipay.sofa</groupId>
    <artifactId>infra-sofa-boot-starter</artifactId>
</dependency>

After the application starts successfully, you can enter in the browser

• 2.x: http://localhost:8080/sofaboot/versions

• 3.x: http://localhost:8080/actuator/versions

Start to accelerate the introduction of asynchronous dependence

The introduction of dependence

SOFABoot in v2.6.0 began offering asynchronous initialization Spring Bean capability, introduced as follows Starter you can:

<dependency>
    <groupId>com.alipay.sofa</groupId>
    <artifactId>runtime-sofa-boot-starter</artifactId>
</dependency>

Instructions

Bean asynchronous principle is to turn on the initialization method initialization (init-method) is responsible for the implementation of a separate thread Bean, so during use, in addition to introducing the above dependency management, but also the definition of Bean disposed in xml async-init="true"attribute specifies whether asynchronous execution Bean the initialization method, for example:

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:sofa="http://sofastack.io/schema/sofaboot"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
            http://sofastack.io/schema/sofaboot   http://sofastack.io/schema/sofaboot.xsd"
       default-autowire="byName">
    <!-- async init  test -->
    <bean id="testBean" class="com.alipay.sofa.runtime.beans.TimeWasteBean" init-method="init" async-init="true"/>
</beans>

Configuration

SOFABoot asynchronous initialization capability provides two configuration attributes for the thread pool size designated for asynchronous execution Bean initialization method (init-method) of:

// 线程池基本大小，默认值为 CPU 核数加一
com.alipay.sofa.boot.asyncInitBeanCoreSize

// 线程池中允许的最大线程数大小，默认值为 CPU 核数加一
com.alipay.sofa.boot.asyncInitBeanMaxSize

Configuration can be provided by VM -D application.yml Spring Boot parameters or configuration files.
