Java 自动生成数据库设计文档-编程知识

Java 自动生成数据库设计文档

背景：有时候急需要数据库设计文档，手写太麻烦，这里介绍一款开源组件，可以自动根据数据库连接生成数据库设计文档

废话不多说，直接上代码

导入maven包

<dependency><groupId>org.freemarker</groupId><artifactId>freemarker</artifactId><version>2.3.30</version></dependency><dependency><groupId>cn.smallbun.screw</groupId><artifactId>screw-core</artifactId><version>1.0.3</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-test</artifactId><scope>test</scope></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><scope>test</scope></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><scope>test</scope></dependency>
