【原】使用mybatis-generator自动生成mapper失败

不忘初心 2019-04-20 围观() 评论() 点赞() 【JAVA开发】

简介：在使用mybatis-generator插件自动生成mapper文件的时候，提示“No plugin found for prefix 'mybatis-generator' in the current project”，因为在pom.xml文件中少了一段plugin配置。

由于在项目中mybatis和jpa的混用，导致大家都很少关注mapper.xml文件的字段了，上周线上出了一个问题，就是因为使用jpa顺手了，增加了字段，下意识的以为会自动处理，所以就没有手动在mapper中增加字段。

今天把最新的字段都整理一遍到mapper中去，表很大，字段太多了，准备使用mybatis插件进行自动生成，然后我拷贝一下，但是在使用mybatis-generator插件自动生成mapper文件的时候，却失败了：

开始还懵逼了一下，看提示信息是仓库中没有找到插件，转念一想不太可能，因为这不是第一次在本机使用这个插件了，之前在别的项目中也使用过，去之前的项目配置中比对了一下，发现在pom.xml文件中少了一段配置：

<plugin>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-maven-plugin</artifactId>
    <configuration>
        <configurationFile>${basedir}/src/main/resources/mybatis/generatorConfig.xml</configurationFile>
        <verbose>true</verbose>
        <overwrite>true</overwrite>
    </configuration>
</plugin>

加上之后，再次执行：mvn mybatis-generator:generate，问题得到解决！
