mapper namespace全限定类名指向其他的子工程
时间: 2023-08-26 22:05:42 浏览: 51
根据引用\[1\]和引用\[2\]的内容,可以使用`<package>`标签来注册指定包下的所有mapper接口。例如,可以使用以下方式来注册其他子工程的mapper接口:
```xml
<package name="com.example.mapper" />
```
这将会注册`com.example.mapper`包下的所有mapper接口。请确保这些mapper接口的名称和映射文件的名称相同,并且它们都放在同一个目录中,以便正确地进行映射。

mapper namespace
Mapper namespace refers to the namespace in which a mapper class is defined. In the context of object-relational mapping (ORM) frameworks like MyBatis, the mapper namespace is used to identify and locate a specific mapper interface or XML file that contains SQL statements or mappings for database operations.
In MyBatis, a mapper namespace is typically declared in the mapper XML file using the `namespace` attribute. This namespace serves as a unique identifier for the mapper and is used to associate it with the corresponding Java interface or class.
For example, in a MyBatis mapper XML file, you might have:
```xml
<mapper namespace="com.example.dao.UserMapper">
<!-- SQL statements and mappings -->
</mapper>
```
Here, the `namespace` attribute specifies that the mapper belongs to the `com.example.dao` package and is named `UserMapper`. This allows you to reference and use this mapper in your MyBatis configuration or Java code by using the fully qualified name `com.example.dao.UserMapper`.
mybatis中mapper namespace
在Mybatis中,mapper namespace是指mapper接口的全类名。namespace用于实现语句与接口的绑定,通过生成mapper接口的代理对象来替代DAO层的设计。如果采用面向接口的编程方式,namespace必须为mapper接口的全类名对象。这样可以确保可以通过namespace来调用对应的mapper接口方法。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
