SpringBoot与Mybatis整合的xxxMapper.java与xxx.Mapper.xml的问题

如果想把二者放在一个文件夹下，不做任何配置的情况会出现错误

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.offcn.mapper.UserMapper.getUserList

解决方案：

1. 把映射文件 放到resources 目录下 结构目录一模一样

2.在pom.xml文件中添加如下

<build>
    <resources>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>false</filtering>
        </resource>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.*</include>
            </includes>
            <filtering>false</filtering>
        </resource>
    </resources>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>
