Flowable開(kāi)發(fā)--Modeler集成(六)

一、Flowable-Modeler功能

https://gitee.com/lwj/flow-modeler-sduty/tree/master/src/main

提供可視化編輯器，編輯BPMN流程，編輯CASE模型，編輯Form表單苏携，編輯App應(yīng)用，編輯決策表
提供可視化參數(shù)配置：每個(gè)流程可以配置詳細(xì)的參數(shù)設(shè)置，按照流程對(duì)應(yīng)的規(guī)范來(lái)設(shè)計(jì)惧蛹。
提供導(dǎo)入導(dǎo)出功能：方便將流程結(jié)果導(dǎo)入到其他應(yīng)用程序
在我們實(shí)際項(xiàng)目中，我們的流程配置和表單都是在一個(gè)系統(tǒng)中操作的，不可能在flowable的war包上做流程配置香嗓。
所以集成modeler是flowable使用的開(kāi)端爵政。

二、源碼下載與編譯

  1. 源碼下載
    下載地址：
    https://github.com/flowable/flowable-engine

    源碼

  2. 導(dǎo)入idea編譯


    導(dǎo)入idea

    編譯

    編譯

編譯結(jié)果：

三陶缺、Modeler集成

1. 拷貝全都靜態(tài)資源到項(xiàng)目中resources

源碼文件

2. Maven依賴

由于flowable-modeler的流程設(shè)計(jì)器頁(yè)面很多操作會(huì)訪問(wèn)后臺(tái)接口钾挟，所以在這里導(dǎo)入依賴文件。

4. 創(chuàng)建流程模型包

創(chuàng)建包：org.flowable.ui
在java中創(chuàng)建包名：org.flowable.ui

創(chuàng)建包

5. 去除認(rèn)證

1）創(chuàng)建org.flowable.ui.common.rest.idm.remote包，添加類：

import org.flowable.ui.common.model.UserRepresentation;
import org.flowable.ui.common.security.DefaultPrivileges;
import org.flowable.ui.common.service.exception.NotFoundException;
import org.flowable.ui.common.service.idm.RemoteIdmService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import java.util.ArrayList;
import java.util.List;

@RestController
@RequestMapping("/app")
public class RemoteAccountResource {

    @Autowired
    private RemoteIdmService remoteIdmService;

    /**
     * GET /rest/account -> get the current user.
     */
    @RequestMapping(value = "/rest/account", method = RequestMethod.GET, produces = "application/json")
    public UserRepresentation getAccount() {
//        UserRepresentation userRepresentation = null;
//        String currentUserId = SecurityUtils.getCurrentUserId();
//        if (currentUserId != null) {
//            RemoteUser remoteUser = remoteIdmService.getUser(currentUserId);
//            if (remoteUser != null) {
//                userRepresentation = new UserRepresentation(remoteUser);
//
//                if (remoteUser.getGroups() != null && remoteUser.getGroups().size() > 0) {
//                    List<GroupRepresentation> groups = new ArrayList<>();
//                    for (RemoteGroup remoteGroup : remoteUser.getGroups()) {
//                        groups.add(new GroupRepresentation(remoteGroup));
//                    }
//                    userRepresentation.setGroups(groups);
//                }
//
//                if (remoteUser.getPrivileges() != null && remoteUser.getPrivileges().size() > 0) {

        UserRepresentation userRepresentation = new UserRepresentation();
        userRepresentation.setFirstName("admin");
        userRepresentation.setLastName("admin");
        userRepresentation.setFullName("admin");
        userRepresentation.setId("admin");
        List<String> pris = new ArrayList<>();
        pris.add(DefaultPrivileges.ACCESS_MODELER);
        pris.add(DefaultPrivileges.ACCESS_IDM);
        pris.add(DefaultPrivileges.ACCESS_ADMIN);
        pris.add(DefaultPrivileges.ACCESS_TASK);
        pris.add(DefaultPrivileges.ACCESS_REST_API);
        userRepresentation.setPrivileges(pris);

        if (userRepresentation != null) {
            return userRepresentation;
        } else {
            throw new NotFoundException();
        }
    }
}

2）創(chuàng)建包：org.flowable.ui.common.security 包添加以下類：

import org.flowable.idm.api.User;
import org.flowable.ui.common.model.RemoteUser;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.context.SecurityContext;

        return null;
    }

    /**
     * @return the {@link User} object associated with the current logged in user.
     */
    public static User getCurrentUserObject() {
        if (assumeUser != null) {
            return assumeUser;
        }

        RemoteUser user = new RemoteUser();

        user.setId("admin");
        user.setDisplayName("admin");
        user.setFirstName("admin");
        user.setLastName("admin");
        user.setEmail("admin@admin.com");
        user.setPassword("test");
        List<String> pris = new ArrayList<>();
        pris.add(DefaultPrivileges.ACCESS_MODELER);
        pris.add(DefaultPrivileges.ACCESS_IDM);
        pris.add(DefaultPrivileges.ACCESS_ADMIN);
        pris.add(DefaultPrivileges.ACCESS_TASK);
        pris.add(DefaultPrivileges.ACCESS_REST_API);
        user.setPrivileges(pris);
        return user;
    }

    public static FlowableAppUser getCurrentFlowableAppUser() {
        FlowableAppUser user = null;
        SecurityContext securityContext = SecurityContextHolder.getContext();
        if (securityContext != null && securityContext.getAuthentication() != null) {
            Object principal = securityContext.getAuthentication().getPrincipal();
            if (principal instanceof FlowableAppUser) {
                user = (FlowableAppUser) principal;
            }
        }
        return user;
    }

    public static boolean currentUserHasCapability(String capability) {
        FlowableAppUser user = getCurrentFlowableAppUser();
        for (GrantedAuthority grantedAuthority : user.getAuthorities()) {
            if (capability.equals(grantedAuthority.getAuthority())) {
                return true;
            }
        }
        return false;
    }

    public static void assumeUser(User user) {
        assumeUser = user;
    }

    public static void clearAssumeUser() {
        assumeUser = null;
    }

}

3）創(chuàng)建包：org.flowable.ui.modeler.conf 添加安全配置類：

6. 啟動(dòng)類配置

修改原有啟動(dòng)類：包名com.xtsz.modeler

package com.xtsz.modeler;

import org.flowable.ui.modeler.conf.ApplicationConfiguration;
import org.flowable.ui.modeler.servlet.AppDispatcherServletConfiguration;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Import;

/**
 * 導(dǎo)入配置
 */
@Import({
        ApplicationConfiguration.class,
        AppDispatcherServletConfiguration.class
})
@SpringBootApplication
public class ModelerApplication {

    public static void main(String[] args) {
        SpringApplication.run(ModelerApplication.class, args);
    }

}

7. 流程模型漢化

拷貝文件到resources目錄：


源漢化文件
目標(biāo)漢化文件

四嫁蛇、啟動(dòng)測(cè)試

  1. 請(qǐng)求地址：http://localhost:8002/flowable-modeler/

    模型流程

  2. 創(chuàng)建流程


    創(chuàng)建流程

    創(chuàng)建流程

    設(shè)計(jì)流程

五锨并、常見(jiàn)問(wèn)題

  1. Cannot convert value '2019-10-22 08:09:24.000000' from column 6 to TIMESTAMP
    原因：MySql數(shù)據(jù)庫(kù)必須使用8.0.0+。
    依賴：
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <scope>runtime</scope>
        </dependency>

數(shù)據(jù)庫(kù)配置：

# 數(shù)據(jù)庫(kù)
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/workflow_flowable?useUnicode=true&characterEncoding=UTF-8&useSSL=false&autoReconnect=true&failOverReadOnly=false&serverTimezone=GMT%2b8&zeroDateTimeBehavior=convertToNull&allowMultiQueries=true
