Use the SANSORM framework to simplify the data in the Java class library to endure

Use the SANSORM framework to simplify the data in the Java class library to endure introduce: In Java development, data persistence is a very important concept.Traditional methods involve many tedious steps, such as creating database connections, writing SQL statements, processing results sets, and so on.To simplify this process and improve development efficiency, we can use the Sansorm framework to simplify the durability of data in the Java library. Sansorm is a lightweight Java persistence framework, which provides a simple and convenient way for data persistence.Using the SANSORM framework, we can define the physical class through annotations and perform database operations through simple APIs. step: The following will introduce how to use the Sansorm framework to simplify the durable data in the Java class library. 1. Introduction dependencies: First of all, you need to add the Sansorm framework to the dependence of the project.The following dependencies can be added to the configuration file of Maven or Gradle: <!-- Maven --> <dependency> <groupId>com.github.marschall</groupId> <artifactId>sansOrm</artifactId> <version>3.2.0</version> </dependency> // Gradle implementation 'com.github.marschall:sansOrm:3.2.0' 2. Create a physical class: Using the SANSORM framework, we can use the annotation to identify the mapping relationship of the physical class and the attribute.For example, we create a physical class called User: @Table(name = "users") public class User { @Id @Column(name = "id") private Long id; @Column(name = "username") private String username; @Column(name = "password") private String password; // omit Getter and Setter } In the above example, the@Table annotation identifies the data table name corresponding to the physical class,@ID annotation identifies the main key field, and the@column annotation identifies ordinary fields. 3. Perform database operation: Using the Sansorm framework, we can perform database operations through simple APIs.The following are several commonly used examples: - Query data: List<User> users = SansOrm.select(User.class).where("username = ?", "admin").execute(); -Stch -in data: User user = new User(); user.setUsername("john"); user.setPassword("123456"); SansOrm.insert(user); - update data: User user = SansOrm.selectById(User.class, 1L); user.setUsername("new_username"); SansOrm.update(user); - delete data: User user = SansOrm.selectById(User.class, 1L); SansOrm.delete(user); Through the above examples, we can see that using the Sansorm framework to simplify the duration of data in the Java class library is very convenient.It provides a simple and easy -to -use API, and can define the mapping relationship between the physical class and the attributes through annotations, avoiding the complicated SQL statement writing and results set processing. Summarize: This article introduces how to use the Sansorm framework to simplify the durable data in the Java class library.By using the SANSORM framework, we can greatly reduce the amount of code for writing and processing database operations and improve development efficiency.I hope this article can help everyone.
