### Ⅰ. Describe what this PR did
Endpoint Exposure
## 1. Server-Side Monitoring Data Endpoints
### 1) Modifications
`server/src/main/java/org/apache/seata/server/config/ServerConfig.java`
**Purpose**: Provides the key component configurations required for
server-side connection-pool monitoring.
```
### 2)Newly Added
`server/src/main/java/org/apache/seata/server/controller/ConnectionPoolController.java`
**Purpose**: Provides REST API endpoints for retrieving and updating
connection-pool metrics.
These APIs are consumed by the frontend service.
```java
@RestController
@RequestMapping("/api/pool")
@CrossOrigin(
origins = {"http://127.0.0.1:30000";, "http://127.0.0.1:8081"},
allowCredentials = "true")
@ConditionalOnProperty(name = "seata.enableConnectionPoolMetrics",
havingValue = "true")
public class ConnectionPoolController {
private final ConnectionPoolService connectionPoolService;
public ConnectionPoolController(ConnectionPoolService
connectionPoolService) {
this.connectionPoolService = connectionPoolService;
}
/**
* Get connection pool metrics by pool type
*
* @return list of connection pool metrics
*/
@GetMapping("/metrics/type/{poolType}")
public ApiResponse<List<ConnectionPoolMetricsVO>>
getMetricsByType(@PathVariable("poolType") PoolType poolType) {
return
ApiResponse.success(connectionPoolService.getMetricsByType(poolType));
}
/**
* Get connection pool metrics for all services
*
* @return list of all connection pool metrics
*/
@GetMapping("/metrics")
public ApiResponse<List<ConnectionPoolMetricsVO>> getAllMetrics() {
return ApiResponse.success(connectionPoolService.getAllMetrics());
}
/**
* Get connection pool configuration by pool type
*
* @return list of connection pool configuration
*/
@GetMapping("/config/type/{poolType}")
public ApiResponse<List<ConnectionPoolConfigVO>>
getConfigByType(@PathVariable("poolType") PoolType poolType) {
return
ApiResponse.success(connectionPoolService.getConfigByType(poolType));
}
/**
* Get connection pool configuration for all services
*
* @return list of all connection pool configuration
*/
@GetMapping("/config")
public ApiResponse<List<ConnectionPoolConfigVO>> getAllConfig() {
return ApiResponse.success(connectionPoolService.getAllConfig());
}
/**
* Update connection pool configuration
*
* @param poolName connection pool name
* @param request configuration update request
* @return operation result
*/
@PutMapping("/config/{poolName}")
public ApiResponse<Boolean> updateConfig(
@PathVariable("poolName") String poolName, @RequestBody
@Validated PoolConfigUpdateRequest request) {
try {
if (poolName == null || request == null) {
return ApiResponse.of(-1, "Invalid request parameters",
false);
}
if (!isValidConfigRequest(request)) {
return ApiResponse.of(-1, "Invalid configuration
parameters", false);
}
request.setPoolName(poolName);
boolean success = connectionPoolService.updateConfig(poolName,
request);
if (success) {
return ApiResponse.success(true);
} else {
return ApiResponse.of(-1, "Failed to update configuration
for service: " + poolName, false);
}
} catch (Exception e) {
return ApiResponse.of(-1, "Error updating configuration: " +
e.getMessage(), false);
}
}
}
```
`server/src/main/java/org/apache/seata/server/metrics/ConnectionPoolService.java`
**Purpose**: Provides the server-side implementation for retrieving
connection-pool metrics.
It obtains cached metrics from`ConnectionPoolInfoCache`and returns them to
callers.
Supporting classes:
- `server/src/main/java/org/apache/seata/server/common/HttpClient.java`
- Http utility class
- `core/src/main/java/org/apache/seata/core/model/ApiResponse.java`
- Unified response wrapper
-
`core/src/main/java/org/apache/seata/core/model/PoolConfigUpdateRequest.java`
- Request body for configuration updates
VO
-
`server/src/main/java/org/apache/seata/server/metrics/vo/ConnectionPoolConfigVO.java`
-
``server/src/main/java/org/apache/seata/server/metrics/vo/ConnectionPoolMetricsVO.java`
## 2.Client-Side Configuration Update Endpoint
### 1)Newly Added
`seata-spring-autoconfigure/seata-spring-autoconfigure-client/src/main/java/org/apache/seata/spring/boot/autoconfigure/controller/ClientConnectionPoolController.java`
**Purpose**: Provides connection-pool configuration update endpoints on the
client side.
These APIs are invoked by the Seata server.
```java
@RestController
@RequestMapping("/client/pool")
public class ClientConnectionPoolController {
private static final Logger LOGGER =
LoggerFactory.getLogger(ClientConnectionPoolController.class);
/**
* Update connection pool configuration.
* This endpoint is called by the Seata server to update client-side
connection pool settings.
*/
@PostMapping("/update")
public ResponseEntity<String> updateConfig(@RequestBody
PoolConfigUpdateRequest request) {
......
}
}
```
