spring - hibernate 5 命名策略配置

使用Spring和Hibernate 5的命名策略配置可以方便地管理数据库表与实体类的映射关系。本文将介绍如何 ，并提供相应的案例代码。

        ...
        com.example.CustomPhysicalNamingStrategy
        com.example.CustomImplicitNamingStrategy
        ...
    

java
public class CustomPhysicalNamingStrategy implements PhysicalNamingStrategy {
    @Override
    public Identifier toPhysicalTableName(Identifier name, JdbcEnvironment context) {
        String tableName = name.getText().toUpperCase();
        return context.getIdentifier(tableName, name.isQuoted());
    }
    @Override
    public Identifier toPhysicalColumnName(Identifier name, JdbcEnvironment context) {
        String columnName = name.getText().toLowerCase();
        return context.getIdentifier(columnName, name.isQuoted());
    }
}
public class CustomImplicitNamingStrategy implements ImplicitNamingStrategy {
    @Override
    public Identifier determinePrimaryTableName(ImplicitEntityNameSource source) {
        String tableName = source.getEntityNaming().getClassName().toUpperCase();
        return source.getBuildingContext().getObjectNameNormalizer().normalizeIdentifier(tableName);
    }
    @Override
    public Identifier determineBasicColumnName(ImplicitBasicColumnNameSource source) {
        String columnName = source.getAttributePath().getProperty();
        return source.getBuildingContext().getObjectNameNormalizer().normalizeIdentifier(columnName);
    }
}

java
@Entity
@Table(name = "employee")
public class Employee {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    @Column(name = "full_name")
    private String fullName;
    // getters and setters
}
