SpringMVC整合Mybatis的对象别名设置方式

原文链接：https://blog.csdn.net/xinghuo0007/article/details/53581239

1.在mybatis_config.xml中Mybatis别名设置

<?xml version="1.0" encoding="UTF-8" ?>  
<!DOCTYPE configuration  
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"  
"http://mybatis.org/dtd/mybatis-3-config.dtd">  
<configuration>  
        <!-- 对象命名空间 -->  
    <typeAliases>  
         <typeAlias alias="Staff" type="com.tongdatech.Staff"/>  
    </typeAliases>  
   <span style="white-space:pre"> </span> <!-- 映射map -->  
    <mappers>  
    </mappers>  
</configuration>  

2.还可以在spring-mybatis.xml中配置：

[html] view plain copy 在CODE上查看代码片派生到我的代码片
<?xml version="1.0" encoding="UTF-8"?>  
<beans xmlns="http://www.springframework.org/schema/beans"  
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"  
    xmlns:aop="http://www.springframework.org/schema/aop"  
    xsi:schemaLocation="  
http://www.springframework.org/schema/beans   
http://www.springframework.org/schema/beans/spring-beans-4.2.xsd   
http://www.springframework.org/schema/tx   
http://www.springframework.org/schema/tx/spring-tx-4.2.xsd  
http://www.springframework.org/schema/aop   
http://www.springframework.org/schema/aop/spring-aop-4.2.xsd  
"> 
<!-- 其他配置省略，主要看别名配置 -->  
<bean id="sqlSessionFactory" class="org.mybatis.spring.sqlSessionfactorybean">  
        <property name="dataSource" ref="dataSource" />  
        <property name="databaseIdProvider" ref="databaseIdProvider" />  
        <property name="mapperLocations" value="classpath*:/mapper/*/oracle/*.xml" />  
        <!-- 给映射的类配置别名 -->  
        <!-- 默认的别名是model类的首字母小写 -->  
        <!-- 如：StaffDeploy实体类。别名为：staffDeploy -->  
        <property name="typeAliasesPackage" value="com.tongdatech.demo.domain;com.tongdatech.sys.domain;com.tongdatech.hr.domain" />   //这里配置了三个包下的所有类的别名
        <property name="plugins">  
            <list>  
                <ref bean="myBatisPaginator" />  
                <ref bean="nullsqlInterceptor" />  
            </list>  
        </property>  
        <property name="configuration">  
            <bean class="org.apache.ibatis.session.Configuration">  
                <property name="objectFactory">  
                    <bean class="com.tongdatech.sys.component.mybatis.PageableObjectFactory" />  
                </property>  
            </bean>  
        </property>  
    </bean>  
</beans>  

在SpringMVC项目中一般都是以第二种为model设置别名。
