前言:
这个网上有很多资料,我查了一下,第一次生成mapper文件夹下没有东西,dao和entity报错,之后又查了一下,报了个错、再查、没有问题了,所以索性记录一下吧;
正文:
pom文件
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.5</version>

<configuration>
<!--允许移动生成的文件 -->

<!-- 是否覆盖 -->
<overwrite>true</overwrite>
<!-- 自动生成的配置 -->
<configurationFile>

</configurationFile>
</configuration>

</build>
有的博客是这样写的:
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.5</version>
<configuration>
<overwrite>true</overwrite>
<verbose>true</verbose>
</configuration>
看出区别了吗,多了一个,添加了之后pom文件报错,去了没有问题了;
配置文件:生成文件的依据
在resource目录下新建xml文件:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration

<!--tableName是数据库中表的名字,domainObjectName是实体的名字-->

</generatorConfiguration>
第一次生成一大片错,果断删除重查,把 中的type=”ANNOTATEDMAPPER”值改为XMLMAPPER
怎么生成呐?上盘Idea傻瓜式教程
图上标注的固定命令,idea是会自己弹出来的,很强大的idea;
这样回到第一张图片,找到刚才起的那个接地气的名字,点击右变绿色箭头,秒秒间文件生成而且没有错哦
小结:
如果没有成功的话,很简单、接着查就好
