Migrate Gateway to Spring Cloud 2024.0.1 / Spring Boot 3.4.3

Browse Source 
- Migrate Gateway module from Spring Cloud 2023.0 to Spring Cloud 2024.0.1
- Upgrade from Spring Boot 3.2.4 to Spring Boot 3.4.3
- Align spring-boot3-starter and observability-spring-boot-3 with same versions
- Update logstash-logback-encoder to version 8.0 for Logback 1.5.x compatibility
- Ensure correct MDC propagation in WebFlux applications

- Verified Gateway container starts correctly with Spring Boot 3.4.3
- Confirmed logging with MDC properties works correctly
- Tested Docker build process with CDS enabled

# GeoServer Cloud Observability Spring Boot 3 Starter
This module provides a Spring Boot 3 compatible version of the observability starter (logging, metrics, tracing) for GeoServer Cloud services, with special support for WebFlux applications and the Gateway service.
## Features
- SLF4J/Logback based logging configuration
- MDC (Mapped Diagnostic Context) enrichment for both servlet and WebFlux applications
- Access logging for both servlet and WebFlux applications
- GeoServer OWS MDC integration
- Full Spring Boot 3 compatibility with Jakarta EE
- Reactive context propagation for MDC in WebFlux applications
- Spring Cloud Gateway integration
## Usage
### Maven Dependency
```xml
<dependency>
<groupId>org.geoserver.cloud</groupId>
<artifactId>gs-cloud-starter-observability-spring-boot-3</artifactId>
</dependency>
```
### Configuration Properties
Various MDC and logging behaviors can be configured through properties:
```yaml
# Access logging configuration
logging:
accesslog:
enabled: true
info-patterns: /api/**, /rest/**
debug-patterns: /events/**
trace-patterns: /**
# MDC configuration properties
geoserver:
mdc:
authentication:
id: true
authorities: true
http:
id: true
remote-addr: true
remote-host: true
method: true
url: true
query-string: true
parameters: false
session-id: true
headers: false
cookies: false
spring:
application-name: true
profile: true
instance-id: true
version: true
properties:
my.custom.property: true
ows:
service: true
service-version: true
operation: true
```
## MDC Propagation in WebFlux
This module includes special support for MDC propagation in reactive applications using WebFlux. The MDC context is maintained throughout the reactive chain using Reactor's context propagation capabilities.
This means that log messages emitted from anywhere in the processing chain will have access to the same MDC properties, even across asynchronous boundaries. This is particularly important for:
- Request tracing
- User identification
- Correlation IDs
- Request metadata
## Gateway Integration
For Spring Cloud Gateway applications, this module also provides:
- GlobalFilter adapters to ensure MDC context is available to all Gateway filters
- Access logging within the Gateway filter chain
- Proper handling of the dual filter chains in Gateway (WebFilter and GlobalFilter)
To use this in the Gateway service:
```xml
<dependency>
<groupId>org.geoserver.cloud</groupId>
<artifactId>gs-cloud-starter-observability-spring-boot-3</artifactId>
</dependency>
```
The Gateway integration will automatically activate when the Spring Cloud Gateway classes are detected on the classpath.

* Auto-configuration for integrating WebFlux MDC filters with Spring Cloud Gateway.
* <p>
* This configuration ensures that both MDC propagation and access logging
* are properly configured and registered as global filters in the gateway.
* <p>
* <h2>Why Both WebFilter and GlobalFilter?</h2>
* While WebFilters like MDCWebFilter and AccessLogWebfluxFilter will automatically run in Spring WebFlux
* applications, Spring Cloud Gateway uses its own filter chain mechanism with important differences:
* <ul>
* <li><b>Separate Filter Chains:</b> Spring WebFlux uses {@code WebFilter} while Spring Cloud Gateway
* uses {@code GlobalFilter}. These are two distinct filter chains that execute independently.</li>
* <li><b>Execution Order:</b> The GlobalFilter chain executes before the WebFilter chain in Gateway,
* so Gateway-specific components (routes, predicates, custom filters) would miss MDC context
* without proper integration.</li>
* <li><b>Complete Request Tracing:</b> To ensure consistent logging across the entire request
* lifecycle, MDC context must be available from the earliest point of request processing.</li>
* </ul>
* <p>
* Without these adapters, you might see logs from the WebFlux filter chain with MDC context, but logs
* from Gateway components would lack this context, resulting in incomplete or inconsistent logging.
* <p>
* This configuration is conditional on the presence of MDCWebFilter and Spring Cloud Gateway classes,
* which are typically provided by the {@code gs-cloud-starter-observability} module's
* optional dependency on Spring Cloud Gateway.
* <p>
* It creates adapter filters that bridge between Spring WebFlux's WebFilter interface and
* Spring Cloud Gateway's GlobalFilter interface, ensuring complete MDC context propagation.

Spring-Boot starter project to treat application observability (logging, metrics, tracing) as a cross-cutting concern.
## WebFlux Applications Note
**Important**: This module only supports servlet-based applications running on Spring Boot 2.7. For WebFlux (reactive) applications or applications using Spring Boot 3, use the Spring Boot 3 compatible module instead:
```xml
<dependency>
<groupId>org.geoserver.cloud</groupId>
<artifactId>gs-cloud-starter-observability-spring-boot-3</artifactId>
<version>${project.version}</version>
</dependency>
```
When using this module in a WebFlux application, MDC properties like request ID, method, URL, etc. will not be available in log messages as Spring Boot 2.7 lacks the necessary reactive context propagation capabilities.

## Logstash formatted JSON Logging
## Logging Features
The `net.logstash.logback:logstash-logback-encoder` dependency allows to write logging entries as JSON-formatted objects in Logstash scheme.
### JSON-formatted Logging
The application must be run with the `json-logs` Spring profile, as defined in [logback-spring.xml](src/main/resources/logback-spring.xml).
The `net.logstash.logback:logstash-logback-encoder` dependency allows writing log entries as JSON-formatted objects in Logstash schema, which is ideal for
log aggregation systems like Elasticsearch, Logstash, and Kibana (ELK stack).
#### Enabling JSON Logging
To enable JSON logging, run the application with the `json-logs` Spring profile:
```bash
java -jar myapp.jar --spring.profiles.active=json-logs
```
Or in Docker/docker-compose:
```yaml
environment:
- SPRING_PROFILES_ACTIVE=json-logs
```
The JSON logging configuration is defined in [logback-spring.xml](src/main/resources/logback-spring.xml).
#### Example JSON Log Output
A basic HTTP request log entry with JSON formatting (without MDC properties) looks like:
```json
{
"@timestamp": "2024-12-16T04:51:11.229-03:00",
"@version": "1",
"message": "POST 201 /geoserver/cloud/rest/workspaces",
"logger_name": "org.geoserver.cloud.accesslog",
"thread_name": "http-nio-9105-exec-2",
"level": "INFO",
"level_value": 20000
}
```
### Mapped Diagnostic Context (MDC)
The observability starter provides rich Mapped Diagnostic Context (MDC) support, making log entries more informative by including contextual
details about requests, authentication, and application information.
#### MDC Configuration Properties
All MDC properties can be enabled/disabled through configuration. Available categories include:
##### **HTTP Request Properties** (`logging.mdc.include.http`):
- `id`: Request ID (ULID format)
- `method`: HTTP method (GET, POST, etc.)
- `url`: Request URL path
- `query-string`: URL query parameters
- `remote-addr`: Client IP address
- `remote-host`: Client hostname
- `session-id`: HTTP session ID
- `headers`: HTTP request headers (filtered by pattern)
- `headers-pattern`: Regex pattern for including headers
- `cookies`: HTTP cookies
- `parameters`: Request parameters
##### **Authentication Properties** (`logging.mdc.include.user`):
- `id`: Authenticated username
- `roles`: User roles
##### **Application Properties** (`logging.mdc.include.application`):
- `name`: Application name
- `version`: Application version
- `instance-id`: Instance identifier
- `active-profiles`: Active Spring profiles
##### **GeoServer Properties** (`logging.mdc.include.geoserver.ows`):
- `service-name`: OWS service name (WMS, WFS, etc.)
- `service-version`: Service version
- `service-format`: Requested format
- `operation-name`: Operation name (GetMap, GetFeature, etc.)
#### Example MDC Configuration
```yaml
logging:
mdc:
include:
user:
id: true
roles: true
application:
name: true
version: true
instance-id: true
active-profiles: true
http:
id: true
method: true
url: true
query-string: false
parameters: false
headers: false
headers-pattern: ".*"
cookies: false
remote-addr: true
remote-host: false
session-id: false
geoserver:
ows:
service-name: true
service-version: true
service-format: true
operation-name: true
```
### Access Logging
The observability starter includes an access logging system that logs incoming HTTP requests with configurable patterns and log levels.
#### Access Log Configuration
Access logging can be configured in your application properties:
```yaml
logging:
# Control behavior of the org.geoserver.cloud.accesslog logging topic
accesslog:
enabled: true
# Requests matching these patterns will be logged at INFO level
info:
- .*\/(rest|gwc\/rest)(\/.*|\?.*)?$
# Requests matching these patterns will be logged at DEBUG level
debug:
- .*\/(ows|ogc|wms|wfs|wcs|wps)(\/.*|\?.*)?$
# Requests matching these patterns will be logged at TRACE level
trace:
- ^(?!.*\/web\/wicket\/resource\/)(?!.*\.(png|jpg|jpeg|gif|svg|webp|ico)(\\?.*)?$).*$
```
The log format includes:
- HTTP method
- Status code
- Request URI path
- Any MDC properties configured (when using JSON logging)
#### Setting Log Levels
Control the access log verbosity with standard log levels:
```yaml
logging:
level:
org.geoserver.cloud.accesslog: INFO # Set to DEBUG or TRACE for more detail
```
### Combining JSON Logging with MDC and Access Logging
For maximum observability, combine JSON logging with MDC properties and access logging:
1. Enable the `json-logs` profile
2. Configure the MDC properties you want to include
3. Enable and configure the access log patterns
4. Set appropriate log levels
This combination provides rich, structured logs that can be easily parsed, filtered, and analyzed by log management systems.
#### Complete Example with MDC Properties
When JSON logging and MDC properties are enabled, a log entry looks like this:
```json
{
"@timestamp": "2024-12-16T04:51:11.229-03:00",
"@version": "1",
"message": "POST 201 /geoserver/cloud/rest/workspaces",
"logger_name": "org.geoserver.cloud.accesslog",
"thread_name": "http-nio-9105-exec-2",
"level": "INFO",
"level_value": 20000,
"enduser.authenticated": "true",
"application.instance.id": "restconfig-v1:192.168.86.128:9105",
"enduser.id": "admin",
"http.request.method": "POST",
"application.version": "1.10-SNAPSHOT",
"http.request.id": "01jf9sjy4ndynkd2bq7g6qx6x7",
"http.request.url": "/geoserver/cloud/rest/workspaces",
"application.name": "restconfig-v1"
}
```
This rich structured format enables powerful filtering and analysis in log management systems. For example, you could easily:
- Filter logs by user (`enduser.id`)
- Track requests across services (`http.request.id`)
- Monitor specific endpoints (`http.request.url`)
- Group logs by application (`application.name`)
- Track application versions (`application.version`)
For OWS requests, GeoServer-specific properties would also be included:
```json
{
...
"gs.ows.service.name": "WMS",
"gs.ows.service.version": "1.3.0",
"gs.ows.service.operation": "GetMap",
"gs.ows.service.format": "image/png"
}
```
