SpringBoot集成Flowable modeler设计器

文章目录

SpringBoot整合Flowable

flowable GitHub仓库：
https://github.com/flowable/flowable-engine

下载源码，或者git clone

找到 modules/flowable-ui-modeler/flowable-ui-modeler-app 模块，拷贝该模块下resource/static/目录下的所有内容至自己项目的resource/static/目录下。

注意：一定要注意源码版本要与项目中的flowable一致，否则会有资源文件获取不到

这里我复制到了 static/modeler/ 目录下

然后启动项目，访问其中的index页面：
http://localhost:10001/modeler/index.html（根据情况修改访问路径）

官方提供首页：

发现少了点东西，f12检查

与官方对比下发现，路径中多了静态资源目录 modeler

我们找到static/modeler/scripts/app-cfg.js 这个文件，做下修改

FLOWABLE.CONFIG = {
	'onPremise' : true,
	'contextRoot' : "",
	'webContextRoot' : "",
	'datesLocalization' : false
};

重启访问index.html

路径是对了，但是还是404错误，account请求是获取登录用户信息的，我们可以实现这个请求，返回一个内置用户，去除登录逻辑；

在项目中全局查找/app/rest/account，在static/modeler/scripts/configuration/url-config.js文件中定义的，我们将请求路径修改一下
在这里插入图片描述
参考官方modeler的响应

在这里插入图片描述

@RestController
@RequestMapping("/modeler/app")
public class AppRestResource {

    @GetMapping("/rest/account")
    public String getAccount() {
        // 参考官方提供的响应数据
        return "{\"id\":\"admin\",\"firstName\":\"Test\",\"lastName\":\"Administrator\",\"email\":\"admin@flowable.org\",\"fullName\":\"Test Administrator\",\"groups\":[],\"privileges\":[\"access-idm\",\"access-rest-api\",\"access-task\",\"access-modeler\",\"access-admin\"]}";
    }
}

重启再访问

这时虽然页面看起来没有问题，但是一些操作还是无法完成的，再看一下static/modeler/scripts/configuration/url-config.js这个文件，其中有很多请求服务端都没有实现的；两种方法：1、参考源码一个个自己实现；2、引入这些请求的源码包

很显然，选择第二种方式，引入源码包

<dependency>
    <groupId>org.flowable</groupId>
    <artifactId>flowable-ui-modeler-rest</artifactId>
    <version>${flowable.version}</version>
</dependency>

重启访问，发现需要登录

在这里插入图片描述
Flowable Security自动配置类org.flowable.spring.boot.FlowableSecurityAutoConfiguration，其在org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration配置前完成自动配置
该类在一个自动配置类中引用，这个配置类在
因此只要排除SecurityAutoConfiguration的自动配置，Flowable Security就不会被配置。在启动类@SpringBootApplication中排除SecurityAutoConfiguration

@SpringBootApplication(
        exclude = {SecurityAutoConfiguration.class}
)

重启访问，发现没有了登陆认证，但是其他操作还是无法操作（http请求404），虽然我们引入了请求源码包，但是SpringBoot并没有扫描这些包

@ComponentScan(basePackages = {
        "org.flowable.ui",
        "top.theonly.flowable.springboot"
})

重启，报错了（日了狗了）

Description:

Parameter 1 of constructor in org.flowable.ui.modeler.service.AppDefinitionPublishService required a bean of type 'org.flowable.ui.modeler.properties.FlowableModelerAppProperties' that could not be found.

The injection point has the following annotations:
	- @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'org.flowable.ui.modeler.properties.FlowableModelerAppProperties' in your configuration.

在AppDefinitionPublishService中，没有找到类型为FlowableModelerAppProperties的bean

在这里插入图片描述
FlowableModelerAppProperties没有交给Spring容器管理。

我们可以定义个类继承FlowableModelerAppProperties，交给Spring容器管理。

@Component
public class CustomFlowableModelerAppProperties extends FlowableModelerAppProperties {
}

重启，又又报错了

FlowableCommonAppProperties中的这三个属性是没有配置，那就配置一下呗
application.properties

# 随便配置，不会用到
flowable.common.app.idm-url=a
flowable.common.app.idm-admin.user=a
flowable.common.app.idm-admin.password=a

重启访问，又报错了（点根烟继续）

mybatis mapper 映射文件找不到
在这里插入图片描述
新建一个mybatis配置文件mybatis-cfg.xml，将上面三个映射文件添加进来

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">

<configuration>
    <mappers>
        <mapper resource="META-INF/modeler-mybatis-mappings/Model.xml"/>
        <mapper resource="META-INF/modeler-mybatis-mappings/ModelHistory.xml"/>
        <mapper resource="META-INF/modeler-mybatis-mappings/ModelRelation.xml"/>
    </mappers>
</configuration>

配置mybatis配置文件位置

mybatis.config-location=classpath:mybatis/mybatis-cfg.xml

重启，又又又又报错

Caused by: java.lang.IllegalArgumentException: No enum constant org.apache.ibatis.type.JdbcType.${blobType}

在这里插入图片描述
将这两个属性在mybatis配置文件中配置一下

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">

<configuration>
    <properties>
        <property name="prefix" value=""/>
        <property name="blobType" value="BLOB"/>
    </properties>
    <mappers>
        <mapper resource="META-INF/modeler-mybatis-mappings/Model.xml"/>
        <mapper resource="META-INF/modeler-mybatis-mappings/ModelHistory.xml"/>
        <mapper resource="META-INF/modeler-mybatis-mappings/ModelRelation.xml"/>
    </mappers>
</configuration>

重启访问，后台又又又又又报错

### Cause: java.sql.SQLSyntaxErrorException: Table 'flowable-springboot2.act_de_model' doesn't exist
; bad SQL grammar []; nested exception is java.sql.SQLSyntaxErrorException: Table 'flowable-springboot2.act_de_model' doesn't exist] with root cause

act_de_model表不存在

使用liquibase生成表

引入依赖

<dependency>
    <groupId>org.liquibase</groupId>
    <artifactId>liquibase-core</artifactId>
    <version>3.6.3</version>
</dependency>

copy flowable-modeler-app-db-changelog.xml到自己项目resource中
在这里插入图片描述
写一个类来生成表

public class FlowableLiquibaseTest {
    public static void main(String[] args) throws SQLException, LiquibaseException {
        DruidDataSource dataSource = new DruidDataSource();
        dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");
        dataSource.setUrl("jdbc:mysql://127.0.0.1:3306/flowable-springboot?useUnicode=true&characterEncoding=utf8&serverTimezone=Asia/Shanghai&nullCatalogMeansCurrent=true&useSSL=false");
        dataSource.setUsername("root");
        dataSource.setPassword("123456");

        DruidPooledConnection connection = dataSource.getConnection();

        DatabaseConnection databaseConnection = new JdbcConnection(connection);
        Database db = DatabaseFactory.getInstance()
                .findCorrectDatabaseImplementation(databaseConnection);

        Liquibase liquibase = new Liquibase("liquibase/flowable-modeler-app-db-changelog.xml",
                new ClassLoaderResourceAccessor(), db);

        liquibase.update("flowable");
    }
}

运行main方法

11:13:08.790 [main] INFO liquibase.lockservice.StandardLockService - Successfully released change log lock

查看数据库，表已生成

那定义一个拦截器，拦截以app开头的路径，设置一个user

public class CustomHandlerInterceptor implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        String servletPath = request.getServletPath();
        if (servletPath.startsWith("/app")) {
            User user = new UserEntityImpl();
            user.setId("admin");
            SecurityUtils.assumeUser(user);
        }
        return true;
    }

}

添加拦截器

@Configuration
public class CustomInterceptorAdapter extends WebMvcConfigurerAdapter {

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new CustomHandlerInterceptor())
                .addPathPatterns("/**");
        super.addInterceptors(registry);
    }
}

重启访问，创建模型，终于成功了
