冷不防 2022-05-15 04:00 90阅读 0赞

generatorConfig.xml的头文件http://mybatis.org/dtd/mybatis-generator-config\_1\_0.dtd标红

### 原因：缺少mybatis-generator-core.jar ###

解决办法：Pom.xml添加依赖

<dependency>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-core</artifactId>
                <version>1.3.5</version>
            </dependency>

### 逆向工程执行错误： ###

原因：pom.xml的plugin中没有配置xml文件路径，它去找默认的文件了，默认的文件路径是src/main/resources，文件名是generatorConfig.xml

### 解决办法： ###

### 1）在该路径下新建generatorConfig.xml文件 ###

### 2）在pom.xml的plugin中配置自定义的xml文件路径及其名字 ###
