报错信息：Invalid bound statement (not found): 找不到绑定的mapper
解决步骤
看target 目录下是否存在mapper.xml 文件，如果不存在的话，应该是因为你的mapper.xml是放在java文件夹下，而不是resources目录下。这就需要在pom.xml文件下配置resources
<resources>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
</resources>
如果还是不行就看下 mapperLocations 的配置路径 mapperLocations="classpath:com/**/mapper/*.xml"
是不是使用了” ** “符号表示，需要将他替换成具体的目录！！！！！！
