1. Positioning

zbus-spring-boot-starter is a Spring Boot starter that integrates zbus for applications using zbus. It provides auto-configuration, property binding, and ready-to-use beans so that applications can consume zbus capabilities with minimal setup.

Dimension	Description
Type	Spring Boot Starter
Consumers	Spring Boot applications using zbus
Core Capabilities	auto-configuration, property binding, ready-to-use beans for zbus
JDK	17
Coordinates	io.github.easy4j:zbus-spring-boot-starter:1.0.0-SNAPSHOT
Config Prefix	zbus

2. Core Capabilities

Capability	Status	Description
Auto-configuration	✅ Stable	Registers zbus beans automatically
Property Binding	✅ Stable	Binds zbus.* to ZbusConsumerEventProperties
Consumer bean	✅ Stable	Auto-registered via ZbusConsumerAutoConfiguration, ZbusProducerAutoConfiguration, ZbusPushEventHandlerAutoConfiguration, ZbusRpcClientAutoConfiguration, ZbusRpcServiceAutoConfiguration

3. Requirements and Compatibility

Dependency	Minimum	Evidence
JDK	17	pom.xml
Spring Boot	2.3.0.RELEASE	pom.xml parent
Maven	3.6+	Maven Enforcer

4. Auto-configuration

The starter auto-configures the following beans:

Bean	Condition	Missing Behavior
Consumer	classpath + property	not created
ZbusConsumerTemplate	classpath + property	not created
DefaultMQProducer	classpath + property	not created
ZbusProducerTemplate	classpath + property	not created
ZbusEventMessageHandler	classpath + property	not created
SpringClientBootstrap	classpath + property	not created
RpcInvoker	classpath + property	not created
ZbusPullConsumerTemplate	classpath + property	not created
ServiceBootstrap	classpath + property	not created
DefaultMQPullConsumer	classpath + property	not created
MQPullConsumerScheduleService	classpath + property	not created
ZbusPullConsumerTemplate	classpath + property	not created

Auto-configuration registration:

• META-INF/spring/org.springframework.boot.autoconfigure.AutoConfiguration.imports (Spring Boot 2.7+ / 3.x / 4.x)
• META-INF/spring.factories (Spring Boot 2.x legacy)

5. Dependency

<dependency>
    <groupId>io.github.easy4j</groupId>
    <artifactId>zbus-spring-boot-starter</artifactId>
    <version>1.0.0-SNAPSHOT</version>
</dependency>

No additional easy4j component dependencies.

6. Quick Start

6.1 Add dependency

Add the dependency above to your pom.xml.

6.2 Configure

zbus:
  enabled: true

6.3 Use the bean

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

Then inject the auto-configured bean in your code:

@Autowired
private Consumer consumer;

7. Configuration Reference

7.1 Config Prefix

zbus

7.2 Configuration Items

Property	Type	Default	Required	Description	Sensitive
zbus.enabled	boolean	true	No	Enable the starter	No

8. Version Lines and Compatibility

Branch	JDK	Spring Boot	Component Version	Status
2.3.x / 2.7.x	8+	2.3.x / 2.7.x	1.0.x	Maintenance
3.0.x ~ 3.5.x	17	3.x	2.0.x	Maintenance
4.0.x / 4.1.x	17+	4.x	3.0.x	Active

9. Build and Test

mvn clean verify
mvn -pl zbus-spring-boot-starter -am test

10. Troubleshooting

Symptom	Diagnosis	Resolution
Bean not created	Check auto-configuration report	Verify zbus.enabled=true and classpath
ClassNotFoundException	Missing dependency	Add the required module
Version conflict	mvn dependency:tree	Use BOM for version alignment
