Common elements of a map file

Schema= "SchemaName"
Default-cascade= "Cascade_style"
Default-access= "field|property| ClassName "
Default-laze= "True|false"
Auto-import= "True|false"
Package= "Package.name"
/>

1.schema (optional): The name of the database schema, and the table name is expanded to the fully qualified name of the table with the specified schema name.

2.default-cascade (optional, default is None): The default cascading style. Specifies a Java attribute and collection class for which the Cascade attribute is not explicitly noted, and Hibernate takes the corresponding default cascading style.

3.default-access (optional, property by default): Hibernate is used to access the properties of the policy, can be customized by implementing the PropertyAccessor interface.

4. The default property is actually accessing and setting properties through the set and get methods of the properties.

5.default-lazy (optional, true by default): Lazy loading, specifying Java properties and collection classes that do not explicitly indicate the lazy attribute, Hibernate takes the corresponding default loading style

6. Lazy loading, such as when we load an object, query the data table and then encapsulate the object, we just load the data table OID to memory, and the other properties are in the database, only when we want to get other properties (such as call get method) We then load the information into memory.

7.auto-import (optional, true by default): Specifies whether we can use a non-fully qualified class name in the query language (limited to classes in this mapping file).

8.package (optional): Specify a package prefix

9. Specify the name prefix for the following class Pojo classes, and if you do not specify a prefix, we need to specify the fully qualified class name
