Automated Configuration

1.Enabling Connection Pool Monitoring

1)Modification

seata-spring-autoconfigure/seata-spring-autoconfigure-client/src/main/java/org/apache/seata/spring/boot/autoconfigure/properties/SeataProperties.java

Purpose: Add a configuration field to enable or disable the connection pool monitoring feature.

 /**
  * enable connection pool metrics
  */
 private boolean enableConnectionPoolMetrics = false;

spring/src/main/java/org/apache/seata/spring/annotation/GlobalTransactionScanner.java

Purpose: Configure whether to enable the connection pool monitoring feature and initialize the client HTTP port.

// init enableConnectionPoolMetrics / httpPort
try {
    if (applicationContext != null) {
        String enableConnectionPoolMetricsStr =
                applicationContext.getEnvironment().getProperty("seata.enableConnectionPoolMetrics");
        if (enableConnectionPoolMetricsStr != null
                && !enableConnectionPoolMetricsStr.trim().isEmpty()) {
            boolean enableConnectionPoolMetrics = Boolean.parseBoolean(enableConnectionPoolMetricsStr);
            RmNettyRemotingClient.getInstance().setEnableConnectionPoolMetrics(enableConnectionPoolMetrics);
        }
        String portStr = applicationContext.getEnvironment().getProperty("server.port");
        if (portStr != null && !portStr.trim().isEmpty()) {
            try {
                int port = Integer.parseInt(portStr.trim());
                RmNettyRemotingClient.getInstance().setHttpPort(port);
            } catch (NumberFormatException e) {
                LOGGER.debug("Invalid server.port in Spring Environment: {}", portStr);
            }
        }
    }
} catch (Throwable t) {
    LOGGER.debug("Failed to resolve server.port from Spring Environment", t);
}

2.Loading Client Endpoint Configuration

1)Modification

seata-spring-autoconfigure/seata-spring-autoconfigure-client/src/main/java/org/apache/seata/spring/boot/autoconfigure/SeataSpringFenceAutoConfiguration.java

Purpose: Load the client-side endpoint (ClientConnectionPoolController), which provides the ability to update connection pool configurations.

@Bean
@ConditionalOnProperty(name = "seata.enableConnectionPoolMetrics", havingValue = "true")
@ConditionalOnClass(name = "org.springframework.web.bind.annotation.RestController")
public ClientConnectionPoolController connectionPoolController() {
    return new ClientConnectionPoolController();
}

Same-Port Hosting

namingserver/src/main/java/org/apache/seata/namingserver/controller/SpaController.java

Purpose:: Add a new front-end entry controller SpaController, forwarding GET /cpmto forward:/cpm/index.html

namingserver/pom.xml

Purpose:

• Use frontend-maven-plugin to run npm ci and npm run build within the front-end directory at build time.
• Use maven-resources-plugin to copy cpm/build/* into namingserver target/classes/static/cpm/, so it can be packaged into the executable JAR.
