GridGain Pro+SpringBoot：Docker部署与缓存配置技术咨询

Hey, sounds like you've already got your GridGain Pro Docker image built and running, and now you're looking to hook up your Spring cache configuration with it. Let's walk through the key steps and considerations to make this integration smooth:

1. Add the Right GridGain Pro Dependencies to Your Spring Project #

First up, you need to include GridGain's Spring Cache integration and core Pro dependencies in your build file. Since this is the Pro version, you'll probably need to configure access to GridGain's private repository (check your license docs for the repo details). For Maven, that looks like:

<dependency>
    <groupId>org.gridgain</groupId>
    <artifactId>gridgain-spring-cache</artifactId>
    <version>your-gridgain-pro-version</version>
</dependency>
<dependency>
    <groupId>org.gridgain</groupId>
    <artifactId>gridgain-core</artifactId>
    <version>your-gridgain-pro-version</version>
</dependency>

Double-check that the versions match the one you used to build your Docker image—mismatched versions can cause weird connection issues.

2. Configure GridGain Client Connection to Your Docker Nodes #

Your existing CustomConfiguration class needs a GridGain client config bean to connect to the Docker-hosted nodes. Here's how to extend it:

@Configuration
@EnableCaching
public class CustomConfiguration extends CachingConfigurerSupport {

    @Bean
    public GridGainConfiguration gridGainConfiguration() {
        GridGainConfiguration cfg = new GridGainConfiguration();
        
        // Enable client mode since we're connecting from a Spring app
        cfg.setClientMode(true);
        
        // Point to your Docker node's address: use host IP + mapped port (if using host networking)
        // Or if using a custom Docker network, use the container name instead of host IP
        cfg.setAddresses(Collections.singletonList("your-host-ip:10800"));
        
        // If you've enabled security in GridGain Pro, add credentials here
        cfg.setSecurityCredentialsProvider(new BasicSecurityCredentialsProvider("username", "password"));
        
        // Add any Pro-specific configs (like encryption, authorization) here to match your Docker node setup
        return cfg;
    }

    @Bean
    @Override
    public CacheManager cacheManager() {
        GridGainCacheManager cacheManager = new GridGainCacheManager();
        cacheManager.setConfiguration(gridGainConfiguration());
        // Optional: set a default cache name if needed
        return cacheManager;
    }

    @Bean
    @Override
    public KeyGenerator keyGenerator() {
        return (target, method, params) -> {
            StringBuilder sb = new StringBuilder();
            sb.append(target.getClass().getName());
            sb.append(method.getName());
            for (Object obj : params) {
                sb.append("|");
                sb.append(obj.toString());
            }
            return sb.toString();
        };
    }
}

A quick note: if your Spring app is also running in a Docker container, put both containers on the same custom Docker network—this lets you use the GridGain container's name (e.g., gridgain-node:10800) instead of the host IP, which is more reliable.

3. Verify Docker Port Mapping & Network Setup #

Make sure your GridGain Docker container is exposing the right ports when you start it. The critical ones for client connections and clustering are:

• 10800: Default TCP client port
• 47100: Node-to-node communication port
• 47500: Node discovery port

A sample run command would be:

docker run -d -p 10800:10800 -p 47100:47100 -p 47500:47500 your-gridgain-pro-image

If using a custom network (recommended for multi-container setups):

# Create the network first
docker network create gridgain-network

# Start GridGain node on the network
docker run -d --network gridgain-network --name gridgain-node your-gridgain-pro-image

# Start your Spring app on the same network
docker run -d --network gridgain-network --name spring-app your-spring-app-image

4. Validate Your Custom KeyGenerator #

Your custom key generator looks like it's building keys from class name, method name, and params—good start! Just keep in mind:

• GridGain requires cache keys to be serializable. Strings are fine, but if any of your params have unstable toString() outputs (e.g., dynamic object states), you might get unexpected cache misses.
• For custom objects, consider using a stable identifier (like an ID field) instead of relying on toString(), or make the object implement Serializable if you decide to use the object itself as part of the key.

5. Sync Pro Feature Configs Between Client & Docker Nodes #

If you're using GridGain Pro features like encryption, role-based access control, or persistence, make sure your Spring client's GridGainConfiguration matches the settings in your Docker node's config. For example, if you enabled cache encryption in the Docker node, you need to add the encryption config to your client bean too:

EncryptionConfiguration encryptionCfg = new EncryptionConfiguration();
encryptionCfg.setKeyStorePath("/path/to/your/keystore");
encryptionCfg.setKeyStorePassword("keystore-password".toCharArray());
cfg.setEncryptionConfiguration(encryptionCfg);

Mismatched configs here will cause connection failures or feature malfunctions.

Once everything is set up, test with a @Cacheable annotated method—call it a few times and check that GridGain is storing/retrieving the cache entries correctly. You can use GridGain's web console or CLI to inspect the cache data if you have those set up.
