# **[springboot-mybatis  Mapper接口与Mapper.xml ][springboot-mybatis _Mapper_Mapper.xml]路径不同时配置不同** #

**方法一：**

1.  如图在同一包下 
2.  ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NpbmF0XzM0MzM4MTYy_size_16_color_FFFFFF_t_70][]

2.修改配置文件

mybatis.mapper-locations=classpath:com/kry/xr/dao/mapper/\*.xml

mybatis.type-aliases-package=com.kry.xr.entity

3.mybatis的mapper.xml文件，我们把它和Mapper.java放一起，都在src/main/java下面，这样利用maven打包时，就要修改pom.xml文件，让它把mapper.xml文件一起打包进jar或者war里了，否则，这些文件不会被打包的。（maven认为src/main/java只是java的源代码路径）

3.1 方法一(l一定要)

<resources>
    			<resource>
    				<directory>src/main/java</directory>
    				<includes>
    					<include>**/*.xml</include>
    				</includes>
    				<filtering>true</filtering>
    			</resource>
                <！-- 一定也要-->
                <resource>
                    <directory>src/main/resources</directory>
                    <includes>
                        <include>**/*</include>
                    </includes>
                </resource>
    		</resources>

3.2方法二

利用build-helper-maven-plugin插件

3.3方法三

利用maven-resources-plugin插件

**方法二：**

1.  不在同包下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NpbmF0XzM0MzM4MTYy_size_16_color_FFFFFF_t_70 1][]

2.配置文件

mybatis.mapper-locations=**classpath:mapper/\*.xml**

mybatis.type-aliases-package=com.kry.xr.entity

3.可加可不加无影响

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NpbmF0XzM0MzM4MTYy_size_16_color_FFFFFF_t_70 2][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NpbmF0XzM0MzM4MTYy_size_16_color_FFFFFF_t_70 3][]
