IDEA 使用junit 做单元测试遇到的问题

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>
