### Ⅰ. Describe what this PR did
# 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.
```java
/**
* 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.
```java
// 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.
```java
@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 /cpm`to` 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.
