Field injection is not recommended 的具体解决办法

Field injection is a method of dependency injection where dependencies are directly injected into class fields. However, it is generally not recommended due to several reasons:
1. Tight coupling: Field injection creates a tight coupling between the class and its dependencies, making it difficult to change or replace those dependencies in the future.
2. Lack of control: With field injection, the dependencies are automatically injected without any explicit control or configuration. This can make it harder to manage and test the dependencies.
3. Difficulties in unit testing: Field injection can make unit testing more challenging because it requires additional setup to mock or replace the injected dependencies.
To address these issues, it is recommended to use constructor injection or setter injection instead. Constructor injection involves passing dependencies as parameters to the class constructor, while setter injection involves using setter methods to inject the dependencies.
By using constructor or setter injection, you can achieve better decoupling, improve testability, and have more control over the dependencies.
