MyBatis mapperLocations、basePackage多数据路径配置

单数据路径配置

多数据路径配置

    
        
        
            
                classpath:com/loongshawn/dao/impl/mapper/*.xml
                classpath:com/loongshawn/dao/impl/mapper3/pmc/*.xml
            
        
        
    

    
    
        
        
    

mapperLocations属性多路径配置如下：

                    
        classpath:com/autonavi/dao/impl/mapper/*.xml              
        classpath:com/autonavi/dao/impl/mapper3/pmc/*.xml
    

basePackage属性多路径配置仅需通过英文逗号”,”分隔开不同路径即可。

以上实现方式均验证无误。
