类 AbstractQueryContainerProvider<T>

java.lang.Object

cn.crane4j.core.support.container.query.AbstractQueryContainerProvider<T>

类型参数:

T - The data type stored in the repository.

所有已实现的接口:

ContainerProvider

直接已知子类:

AbstractNamespaceResolvableQueryContainerProvider

已过时。

This class is still used, but it will be refactored in the future.

@Deprecated
public abstract class AbstractQueryContainerProvider<T>
extends Object
implements ContainerProvider

Provides functionality to generate a specific MethodInvokerContainer object that supports generating SQL statements based on specified conditions and invoking the repository to execute the SQL, thereby retrieving data from the database.

Implementation

The implementing class must provide a repository information object that implements the AbstractQueryContainerProvider.Repository interface (typically as an inner class).
It should also implement the createRepository(java.lang.String, T) method to create this object when registering the repository.
This object will provide necessary functionality during SQL statement generation, including:

• Retrieving the entity class type associated with the repository;
• Converting the specified property names in the JavaBean to query fields in SQL;
• Obtaining the table name for querying in SQL;

Cache

The registered AbstractQueryContainerProvider.Repository (t) and generated MethodInvokerContainer will be cached.
Therefore, duplicate registration of the same AbstractQueryContainerProvider.Repository is not supported, and duplicate creation of the same MethodInvokerContainer will be avoided.
This cache is typically released only during JVM garbage collection. If necessary, you can manually invoke destroy() to clear all caches.
