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

這個錯誤是沒找到對應的mapper接口，檢查namespace寫對了沒

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

出現這個錯誤的原因xml文件沒有被編譯，在pom文件裏build標簽下面加入如下即可解決

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