Spring Boot Starter

Integrates Redisson with Spring Boot library. Depends on Spring Data Redis module.

Supports Spring Boot 1.3.x - 3.3.x

Usage

1. Add redisson-spring-boot-starter dependency into your project:

Maven

<dependency>
     <groupId>org.redisson</groupId>
     <artifactId>redisson-spring-boot-starter</artifactId>
     <version>xVERSIONx</version>
</dependency>

Gradle

compile 'org.redisson:redisson-spring-boot-starter:xVERSIONx'

redisson-spring-boot-starter depends on redisson-spring-data module compatible with the latest version of Spring Boot. Downgrade redisson-spring-data module if necessary to support previous Spring Boot versions:

redisson-spring-data module name	Spring Boot version
redisson-spring-data-16	1.3.y
redisson-spring-data-17	1.4.y
redisson-spring-data-18	1.5.y
redisson-spring-data-2x	2.x.y
redisson-spring-data-3x	3.x.y

For Gradle, you can downgrade to redisson-spring-data-27 this way:

implementation ("org.redisson:redisson-spring-boot-starter:xVERSIONx") {
   exclude group: 'org.redisson', module: 'redisson-spring-data-33'
}
implementation "org.redisson:redisson-spring-data-27:xVERSIONx"

2. Add settings into application.settings file

Using common Spring Boot 3.x+ settings:

spring:
  data:
    redis:
      database: 
      host:
      port:
      password:
      ssl: 
      timeout:
      connectTimeout:
      clientName:
      cluster:
        nodes:
      sentinel:
        master:
        nodes:

Using common Spring Boot up to 2.7.x settings:

spring:
  redis:
    database: 
    host:
    port:
    password:
    ssl: 
    timeout:
    connectTimeout:
    clientName:
    cluster:
      nodes:
    sentinel:
      master:
      nodes:

FAQ

Q: How to replace Netty version brought by Spring Boot?

You need to define netty version in properties section of your Maven project.

    <properties>
          <netty.version>4.1.107.Final</netty.version> 
    </properties>

Q: How to disable Redisson?

You may not have Redis or Valkey in some environments. In this case Redisson can be disabled:

• Using Annotations
  Spring Boot 2.7+

@SpringBootApplication
@EnableAutoConfiguration(exclude = {
    RedissonAutoConfigurationV2.class})
public class Application {
   
    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }
}

Spring Boot up to 2.6

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

• Using application.yml file
  Spring Boot 2.7+

spring:
  autoconfigure:
    exclude:
      - org.redisson.spring.starter.RedissonAutoConfigurationV2

Spring Boot up to 2.6

spring:
  autoconfigure:
    exclude:
      - org.redisson.spring.starter.RedissonAutoConfiguration

{% include 'cache/Spring-cache.md' %}

Spring Session

Please note that Redis or Valkey notify-keyspace-events setting should contain Exg letters to make Spring Session integration work.

Ensure you have Spring Session library in your classpath, add it if necessary:

Maven

<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-core</artifactId>
    <version>3.2.1</version>
</dependency>

<dependency>
   <groupId>org.redisson</groupId>
   <artifactId>redisson-spring-data-33</artifactId>
   <version>xVERSIONx</version>
</dependency>

Gradle

compile 'org.springframework.session:spring-session-core:3.2.1'

compile 'org.redisson:redisson-spring-data-33:xVERSIONx'

Spring Http Session configuration

Add configuration class which extends AbstractHttpSessionApplicationInitializer class:

@Configuration
@EnableRedisHttpSession
public class SessionConfig extends AbstractHttpSessionApplicationInitializer { 

     @Bean
     public RedissonConnectionFactory redissonConnectionFactory(RedissonClient redisson) {
         return new RedissonConnectionFactory(redisson);
     }

     @Bean(destroyMethod = "shutdown")
     public RedissonClient redisson(@Value("classpath:/redisson.yaml") Resource configFile) throws IOException {
        Config config = Config.fromYAML(configFile.getInputStream());
        return Redisson.create(config);
     }

}

Spring WebFlux’s Session configuration

Add configuration class which extends AbstractReactiveWebInitializer class:

@Configuration
@EnableRedisWebSession
public class SessionConfig extends AbstractReactiveWebInitializer { 

     @Bean
     public RedissonConnectionFactory redissonConnectionFactory(RedissonClient redisson) {
         return new RedissonConnectionFactory(redisson);
     }

     @Bean(destroyMethod = "shutdown")
     public RedissonClient redisson(@Value("classpath:/redisson.yaml") Resource configFile) throws IOException {
        Config config = Config.fromYAML(configFile.getInputStream());
        return Redisson.create(config);
     }
}

Spring Boot configuration

1. Add Spring Session Data Redis library in classpath:
   Maven:

<dependency>
  <groupId>org.springframework.session</groupId>
  <artifactId>spring-session-data-redis</artifactId>

Spring Transaction Manager

Redisson provides implementation of both org.springframework.transaction.PlatformTransactionManager and org.springframework.transaction.ReactiveTransactionManager interfaces to participant in Spring transactions. See also Transactions section.

Spring Transaction Management

@Configuration
@EnableTransactionManagement
public class RedissonTransactionContextConfig {
    
    @Bean
    public TransactionalBean transactionBean() {
        return new TransactionalBean();
    }
    
    @Bean
    public RedissonTransactionManager transactionManager(RedissonClient redisson) {
        return new RedissonTransactionManager(redisson);
    }
    
    @Bean(destroyMethod="shutdown")
    public RedissonClient redisson(@Value("classpath:/redisson.yaml") Resource configFile) throws IOException {
         Config config = Config.fromYAML(configFile.getInputStream());
        return Redisson.create(config);
    }
    
}


public class TransactionalBean {

    @Autowired
    private RedissonTransactionManager transactionManager;

    @Transactional
    public void commitData() {
        RTransaction transaction = transactionManager.getCurrentTransaction();
        RMap<String, String> map = transaction.getMap("test1");
        map.put("1", "2");
    }

}

Reactive Spring Transaction Management

@Configuration
@EnableTransactionManagement
public class RedissonReactiveTransactionContextConfig {
    
    @Bean
    public TransactionalBean transactionBean() {
        return new TransactionalBean();
    }
    
    @Bean
    public ReactiveRedissonTransactionManager transactionManager(RedissonReactiveClient redisson) {
        return new ReactiveRedissonTransactionManager(redisson);
    }
    
    @Bean(destroyMethod="shutdown")
    public RedissonReactiveClient redisson(@Value("classpath:/redisson.yaml") Resource configFile) throws IOException {
         Config config = Config.fromYAML(configFile.getInputStream());
        return Redisson.createReactive(config);
    }
    
}

public class TransactionalBean {

    @Autowired
    private ReactiveRedissonTransactionManager transactionManager;

    @Transactional
    public Mono<Void> commitData() {
        Mono<RTransactionReactive> transaction = transactionManager.getCurrentTransaction();
        return transaction.flatMap(t -> {
            RMapReactive<String, String> map = t.getMap("test1");
            return map.put("1", "2");
        }).then();
    }

}

Spring Cloud Stream

This feature is available only in Redisson PRO edition.

Redisson implements Spring Cloud Stream integration based on the reliable Redis Stream structure for message delivery. To use Redis binder with Redisson you need to add Spring Cloud Stream Binder library in classpath:

Maven:

<dependency>
    <groupId>pro.redisson</groupId>
    <artifactId>spring-cloud-stream-binder-redisson</artifactId>
    <version>xVERSIONx</version>
</dependency>

Gradle:

compile 'pro.redisson:spring-cloud-stream-binder-redisson:xVERSIONx'  

Compatible with Spring versions below.

Spring Cloud Stream	Spring Cloud	Spring Boot
4.1.x	2023.0.x	3.0.x, 3.1.x, 3.2.x
4.0.x	2022.0.x	3.0.x, 3.1.x, 3.2.x
3.2.x	2021.0.x	2.6.x, 2.7.x (Starting with 2021.0.3 of Spring Cloud)
3.1.x	2020.0.x	2.4.x, 2.5.x (Starting with 2020.0.3 of Spring Cloud)

Receiving messages

Register the input binder (an event sink) for receiving messages as follows:

@Bean
public Consumer<MyObject> receiveMessage() {
  return obj -> {
     // consume received object ...
  };
}

Define channel id in the configuration file application.properties. Example for receiveMessage bean defined above connected to my-channel channel:

spring.cloud.stream.bindings.receiveMessage-in-0.destination=my-channel

Publishing messages

Register the output binder (an event source) for publishing messages as follows:

@Bean
public Supplier<MyObject> feedSupplier() {
	return () -> {
           // ...
           return new MyObject();
	};
}

Define channel id in the configuration file application.properties. Example for feedSupplier bean defined above connected to my-channel channel:

spring.cloud.stream.bindings.feedSupplier-out-0.destination=my-channel
spring.cloud.stream.bindings.feedSupplier-out-0.producer.useNativeEncoding=true

Spring Data Redis
