org.apache.ibatis.builder.BuilderException: Wrong namespace. Expected 'com.sc.starry_sky.dao.UserMapper' but found 'UserMapper'.

 

这个错误是没找到对应的mapper接口，检查namespace写对了没

 

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found)

 

出现这个错误的原因xml文件没有被编译，在pom文件里build标签下面加入如下即可解决

<resources>
    <resource>
        <directory>src/main/java</directory>
        <includes>
            <include>**/*.xml</include>
        </includes>
        <filtering>true</filtering>
    </resource>
</resources>
