Understand the SANSORM framework: simplify the ORM development in the Java class library
Introduction:
Sansorm is an open source Java class library, which aims to simplify ORM (object relationship mapping) development process.ORM is a technology that connects a relationship database to object -oriented programming language. It allows developers to use object -oriented methods to operate databases.
The Sansorm framework provides a simple and powerful way to perform basic ORM operations, thereby reducing the workload of developers at database access layers.It uses a lightweight design concept, so that developers using this framework can quickly get started and concentrate on solving more important problems.
characteristic:
1. Simple and easy to use: The Sansorm framework provides a simple API, allowing developers to easily perform database operations, such as inserting, updating, deleting and querying.
2. High performance: The Sansorm framework optimizes the database operation, provides high -performance query and update functions, and also supports the use of database connection pools.
3. Zero Configuration: The Sansorm framework uses the method of annotation driver. It does not require tedious configuration files to reduce the workload of developers.
4. Support multiple databases: SANSORM framework supports a variety of common databases, such as MySQL, Oracle, Postgresql, etc.Developers can choose the right database according to their needs.
Example code:
Here are a Java code example using the Sansorm framework for data operation:
import com.sansorm.SansOrm;
import com.sansorm.annotations.Entity;
import com.sansorm.annotations.Id;
import com.sansorm.annotations.Table;
@Entity
@Table(name = "students")
public class Student {
@Id
private int id;
private String name;
private int age;
// omit the creation function and getter/setter method
public static void main(String[] args) {
Sansorm.init (); // initialize the sansorm framework
// Create a Student object
Student Student = New Student (1, "Zhang San", 20);
// Insert data to the database
SansOrm.insert(student);
// Query data
Student queriedStudent = SansOrm.selectById(Student.class, 1);
System.out.println (queriedStudent.getName ()); // Output: "Zhang San"
// update data
queriedStudent.setAge(21);
SansOrm.update(queriedStudent);
// delete data
SansOrm.delete(queriedStudent);
Sansorm.shutdown (); // Close the sansorm framework
}
}
Summarize:
The SANSORM framework is a simple and easy -to -use, high -performance Java Orm framework, which aims to simplify the development of database access layers.It provides a simple API, supports a variety of common databases, and configures the method of annotation drive, so that developers can focus on the realization of business logic.If you are looking for a solution to simplify the ORM development process, the Sansorm framework is worth trying.
