ruoyi flowable

  1. 集成flowable

1.1导入maven依赖

  1. <flowable.version>6.7.0</flowable.version>
  2. <!--flowable 主依赖-->
  3. <dependency>
  4.     <groupId>org.flowable</groupId>
  5.     <artifactId>flowable-spring-boot-starter</artifactId>
  6.     <version>${flowable.version}</version>
  7. </dependency>

  1. 集成flowable-modeler

2.1 maven依赖

  1. <!-- flowable 集成依赖conf ,包内包含 rest，logic -->
  2. <dependency>
  3.     <groupId>org.flowable</groupId>
  4.     <artifactId>flowable-ui-modeler-conf</artifactId>
  5.     <version>${flowable.version}</version>
  6.     <exclusions>
  7.         <exclusion>
  8.             <groupId>org.mybatis</groupId>
  9.             <artifactId>mybatis</artifactId>
  10.         </exclusion>
  11.         <exclusion>
  12.             <groupId>org.mybatis</groupId>
  13.             <artifactId>mybatis-spring</artifactId>
  14.         </exclusion>
  15.     </exclusions>
  16. </dependency>

前端下载

地址：GitHub - flowable/flowable-engine: A compact and highly efficient workflow and Business Process Management (BPM) platform for developers, system admins and business users.

直接将github上flowable-engine项目（GitHub - flowable/flowable-engine: A compact and highly efficient workflow and Business Process Management (BPM) platform for developers, system admins and business users.）version 6.7.0 （分支 origin/flowable-release-6.7.0）的前端代码拷贝到自己项目中，路径保持相同：flowable-engine-6.7.0\modules\flowable-ui-modeler\flowable-ui-modeler-app\src\main\resources

2.2 flowable的yml配置

  1. flowable:
  2.   # 关闭异步，不关闭历史数据的插入就是异步的，会在同一个事物里面，无法回滚
  3.   # 开发可开启会提高些效率，上线需要关闭
  4.   database-schema-update: true
  5.   process-definition-location-prefix: classpath*:/processes/
  6.   process-definition-location-suffixes: "**.bpmn20.xml, **.bpmn"
  7.   common:
  8.     app:
  9.       idm-url: http://localhost:${server.port}/flowable-idm1
  10.       idm-admin:
  11.         user: admin
  12.         password: test
  13.   #解决乱码问题
  14.   activity-font-name: 宋体
  15.   label-font-name: 宋体
  16.   annotation-font-name: 宋体
  17.   #关闭定时任务JOB
  18.   async-executor-activate: false

2.3路径重定向配置

（用于路径跳转直接可免去index.html）

  1.  
  2.     @Override
  3.     public void addViewControllers(ViewControllerRegistry registry) {
  4.         registry.addViewController("/").setViewName("forward:" + indexUrl);
  5.         registry.addViewController("/modeler").setViewName("forward:/modeler/index.html");
  6.     }

2.4免登录配置

类名随意定，如FlowableSecurityConfiguration.class，包路径与flowable相同：org.flowable.ui.modeler.conf

  1.  
  2. import org.flowable.ui.common.security.SecurityConstants;
  3. import org.springframework.context.annotation.Configuration;
  4. import org.springframework.core.annotation.Order;
  5. import org.springframework.security.config.annotation.web.builders.HttpSecurity;
  6. import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
  7. import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
  8.  
  9. @Configuration(proxyBeanMethods = false)
  10. @EnableWebSecurity
  11. public class FlowableSecurityConfiguration {
  12.  
  13.     @Configuration
  14.     @Order(SecurityConstants.TASK_API_SECURITY_ORDER)
  15.     public static class ModelerApiWebSecurityConfigurationAdapter extends WebSecurityConfigurerAdapter {
  16.  
  17.         @Override
  18.         protected void configure(HttpSecurity http) throws Exception {
  19.             http
  20.                     //必须要将csrf设置为disable，不然后面发送POST请求时会报403错误
  21.                     .csrf().disable()
  22.                     //为了简单起见，简单粗暴方式直接放行modeler下面所有请求
  23.                     .authorizeRequests().antMatchers("/modeler/**").permitAll();
  24.             //解决iframe无法访问问题
  25.             http.csrf().disable().headers().frameOptions().sameOrigin();
  26.         }
  27.     }
  28. }

2.5 数据库链接配置

2.6.2MyBatisConfig.class修改

屏蔽内部所有方法，继承上边的自动化配置类，增加注解和注入bean

  1.

  3. import org.mybatis.spring.SqlSessionTemplate;

  42.         return getSqlSessionTemplate(sqlSessionFactory, properties);
  43.     }
  44. }

2.6.3yml修改mybatis配置

让其支持BLOB

  1. # MyBatis
  2. mybatis:
  3.   # 搜索指定包别名
  4.   typeAliasesPackage: org.morfly.kdla.pdmp.**.domain
  5.   # 配置mapper的扫描，找到所有的mapper.xml映射文件
  6.   mapperLocations: mapper/*/*.xml,classpath*:mapper/*.xml,classpath:/META-INF/modeler-mybatis-mappings/*.xml
  7.   # 加载全局的配置文件
  8.   configLocation: classpath:mybatis/mybatis-config.xml
  9.   # 参数配置
  10.   configuration-properties:
  11.     # 配置流程引擎参数，详情可见 DatabaseConfiguration
  12.     blobType: BLOB
  13.     boolValue: TRUE
  14.     # 不要设置库名，否则会出现双库名 bug
  15.     prefix: ''
