Bean Manager Parent Trunk framework architecture design and module layered principle explanation
Overview:
The Bean Manager Parent Trunk framework is a lightweight framework for the development of Java applications.This article will focus on the architecture design and module layering of the framework, as well as related programming code and configuration description.
1. architecture design
The architecture design of the Bean Manager Parent Trunk framework mainly includes the following components:
1. Core Module: The core module is the basis of the entire framework, which contains core functions and basic components.This module provides Bean's management mechanism and related operation methods, as well as management and calls on external dependence.It also defines the basic architecture and interface specifications of the framework, providing basic services for other modules.
2. Extension Module: The expansion module is a module that expands functional extensions on the basis of the core module.It provides more functions and components to meet specific needs.Developers can selectively use the extension module according to the actual situation to expand the framework.
3. Integration Module: Integrated module is used to integrate with external systems.This module provides interfaces and methods interacting with other systems to facilitate data transmission and sharing of framework and external systems.Through integrated modules, developers can easily integrate with other systems to improve the flexibility and interoperability of the system.
4. Business Module: The business module is a module developed according to specific business needs.It should expand on the basis of the core module and provide specific business logic and business components.In the business module, developers can encode and configure according to actual needs to achieve business functions.
2. Module layering principle
The Bean Manager Parent Trunk framework uses a module -layered design principle to better manage and organize code.Below is the layered principle of the framework of the frame:
1. The upper module depends on the lower module: the upper module cannot depend on the lower module. The dependency relationship between the modules should be one -way dependencies from top to bottom.This can ensure the independence and scalability of the module, which is convenient for development and maintenance alone.
2. The interaction between the modules: the interaction between the modules should be performed through the interface instead of directly reference the other party's class.This can reduce the coupling between modules, improve the replication and maintenance of code.
3. Configure the configuration file between the modules: the configuration between the modules should be performed through the configuration file instead of hard codes in the code.This can improve the configurable and scalability of the framework, reduce the demand for modification and re -compilation of code.
4. Communicate through events and messages between modules: communication between modules can be performed through events and messages to reduce direct coupling and dependencies between modules.Through events and messages, it can realize the decoupling and loosening between modules, and improve the scalability and flexibility of the framework.
Third, code and configuration description
In order to better understand and apply the Bean Manager Parent Trunk framework, the following is a related programming code and configuration example:
1. Code code for the core module:
// Define the core module interface
public interface CoreModule {
// The basic functions and methods of the core module
void doSomething();
}
// Implement the core module interface
public class CoreModuleImpl implements CoreModule {
@Override
public void doSomething() {
// Implement the specific function of the core module
}
}
2. Example of the code of the expansion module:
// Define the expansion module interface
public interface ExtensionModule {
// The functions and methods of the expansion module
void doSomethingMore();
}
// Implement the expansion module interface
public class ExtensionModuleImpl implements ExtensionModule {
@Override
public void doSomethingMore() {
// Implement the specific function of the extension module
}
}
3. Code example of integrated module:
// Define the integrated module interface
public interface IntegrationModule {
// The interface and method of the integrated module
void connectToExternalSystem();
}
// Implement the integrated module interface
public class IntegrationModuleImpl implements IntegrationModule {
@Override
public void connectToExternalSystem() {
// Realize the connection and interaction with the external system
}
}
4. Code example of the business module:
// Define the business module interface
public interface BusinessModule {
// The interface and method of the business module
void doBusinessLogic();
}
// Implement the business module interface
public class BusinessModuleImpl implements BusinessModule {
private CoreModule coreModule;
private ExtensionModule extensionModule;
private IntegrationModule integrationModule;
public BusinessModuleImpl(CoreModule coreModule, ExtensionModule extensionModule, IntegrationModule integrationModule) {
this.coreModule = coreModule;
this.extensionModule = extensionModule;
this.integrationModule = integrationModule;
}
@Override
public void doBusinessLogic() {
// Methods to execute business logic and call other modules
coreModule.doSomething();
extensionModule.doSomethingMore();
integrationModule.connectToExternalSystem();
}
}
In summary, the Bean Manager Parent Trunk framework realizes the organizational and management of code through reasonable architecture design and module layering, which improves the scalability and flexibility of the system.Developers can selectively use different modules according to actual needs to meet different business needs and functional requirements.At the same time, write the corresponding code and configuration according to the specific situation to achieve the function and business logic of the framework.
