springboot集成flowableui

先下载源码

Release Flowable 6.7.2 release · flowable/flowable-engine · GitHub

选择zip文件,下载,解压

然后进入E:\flowable-engine-flowable-6.7.2\flowable-engine-flowable-6.7.2\modules

然后这个flowable-ui的文件夹拷贝到一个你自己新建的workflow文件夹里面

然后再idea中导入项目

如果报这个错误

在pom中加入这一部分代码

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <scope>compile</scope>
</dependency>

如果报下面的错误,找到57行

spring-boot-starter-tomcat的scope

provided改成compile

然后刷新maven 启动项目

浏览器输入http://localhost:8080/flowable-ui/

账号admin 密码test

接下来,我们要吧flowable-ui集成到自己的springboot项目中

在pom文件添加这些数据

</project>

然后把flowable-ui项目的flowable-default.properties文件拿过来

注释端口号,注释h2数据库，并且修改成mysql数据库

自己的数据库要先建一个flowable的名字

主要关注这部分的内容

这是文件内容

然后新建一个目录，下面是我的目录,你可以改动

com.dmg.flowable.ui

然后把FlowableUiApplication和FlowableUiAppEventRegistryCondition

把放入com.dmg.flowable.ui目录下

账号admin 密码test

就可以看到界面了

我们可以看下数据库,第一次会创建87张表
