403-403: Useful new configuration property for flexibility!The new
apollo.override-system-propertiesconfiguration property in version 2.1.0+ is a helpful addition to provide flexibility in controlling whether Apollo's remote properties should override Java's system properties. The documentation clearly explains its purpose and the order of precedence for configuration.
407-407: Helpful new configuration property for gray releases!The new
apollo.labelconfiguration property is a useful addition to allow specifying the label information for the application, which is important for configuring gray release rules. The documentation clearly explains its purpose and the order of precedence for configuration.

453-453: Excellent support for Spring Boot 2.4+ and WebClient extension!The addition of Config Data Loader support for Spring Boot 2.4+ and Apollo Client 1.9.0+, along with the ability to extend the HTTP client using WebClient, is a great enhancement. The documentation provides clear instructions on the required dependencies, configuration properties, and the extensibility point for customizing the WebClient through an SPI implementation.

403-489: Comprehensive guide on ConfigMap caching in Kubernetes.This new section provides detailed information about ConfigMap caching for Apollo clients in Kubernetes environments. It covers:
- Version compatibility
- Configuration properties
- Naming conventions for ConfigMaps
- Steps to grant necessary permissions to the Pod's Service Account
The content is well-structured and informative. However, there are a few minor improvements that could be made:
The code blocks for Kubernetes resources (ServiceAccount, Role, RoleBinding, Pod) are not specified with a language. Adding
yamlas the language would improve syntax highlighting.The numbered list for granting permissions is not properly formatted in Markdown, which may affect rendering.
Consider applying the following changes to improve formatting:
- Add
yamlto the code blocks. For example:- ``` + ```yaml apiVersion: v1 kind: ServiceAccount metadata: name: my-service-account namespace: my-namespace ``` 2. Fix the numbered list formatting by adding a blank line after each item. For example: ```diff 1. 创建Service Account: 如果还没有Service Account，你需要创建一个。 + 2. 创建Role或ClusterRole: 定义一个Role或ClusterRole，授予对特定ConfigMap的读写权限。如果ConfigMap是跨多个Namespace使用的，应该使用ClusterRole。 + 3. 绑定Service Account到Role或ClusterRole: 使用RoleBinding或ClusterRoleBinding将Service Account绑定到上面创建的Role或ClusterRole。These changes will improve the readability and rendering of the documentation.

403-490: Comprehensive addition of ConfigMap caching information.This new section provides detailed information about ConfigMap caching in Kubernetes environments for Apollo client version 2.4.0 and above. The content is well-structured and informative, covering:
- Version applicability
- Purpose and benefits of ConfigMap caching
- Configuration properties
- Structure of cached data
- Detailed instructions for granting necessary permissions
The information appears to be complete and valuable for users implementing Apollo in Kubernetes environments.
However, there are a few minor improvements that could be made:
- Consider adding a brief introduction explaining why ConfigMap caching is beneficial in Kubernetes environments.
- The code blocks for Kubernetes configurations (ServiceAccount, Role, RoleBinding, Pod) should have a language specifier for proper syntax highlighting.
To improve readability and syntax highlighting, add language specifiers to the code blocks. For example:
- ``` + ```yaml apiVersion: v1 kind: ServiceAccount metadata: name: my-service-account namespace: my-namespace ```Apply similar changes to the other code blocks in this section.
