springboot2.x+h2+activiti6环境搭建记录

由于需要用到activiti6工作流，经过艰难的配置终于把环境搭起来了，结合查的和自己踩的坑，记录下过程，以备后用。

1.eclipse安装activi插件

我的eclipse是Eclipse IDE for RCP and RAP Developers，在线安装一直失败，最终离线安装搞定。

参照https://blog.csdn.net/qq_24583853/article/details/85270214安装成功

2.配置h2数据库和activiti6

配置文件配置如下，采用本地文件方式存储

#配置数据库h2的参数
spring.datasource.url=jdbc:h2:./db/H2/testdb
spring.datasource.driver-class-name=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=sa

spring.h2.console.enabled=true

spring.activiti.database-schema-update=true

spring.activiti.check-process-definitions=false
spring.activiti.process-definition-location-prefix: classpath:/processes/

3.pom的主要配置

        org.springframework.boot
        spring-boot-starter-parent
        2.2.6.RELEASE
         
    

            org.mybatis.spring.boot
            mybatis-spring-boot-starter
            2.1.2
        
            com.h2database
            h2
            runtime
        
        
            org.activiti
            activiti-spring-boot-starter-basic
            6.0.0
        
    org.activiti
    activiti-common-rest
    6.0.0

            org.projectlombok
            lombok
            true
        

4.参数加载配置代码

对于数据库和mybatis参数用config配置类进行加载如下：

• 
  @Configuration
  @ConfigurationProperties(prefix = "spring.datasource")
  @MapperScan(basePackages = { DataSourceConstants.MAPPER_PACKAGE }, sqlSessionFactoryRef = "mybatisSqlSessionFactory")
  public class DataSourceConfig {
  
      private String url;
  
      private String username;
  
      private String password;
      
      @Bean(name = "mybatisDataSource")
      public DataSource mybatisDataSource() {
          DruidDataSource dataSource = new DruidDataSource();
          dataSource.setDriverClassName("org.h2.Driver");
          dataSource.setUrl(url);
          dataSource.setUsername(username);
          dataSource.setPassword(password);
          return dataSource;
      }
  
      @Bean(name = "mybatisTransactionManager")
      public DataSourceTransactionManager mybatisTransactionManager() {
          return new DataSourceTransactionManager(mybatisDataSource());
      }
  
  	@Bean
  
  	public SqlSessionTemplate sqlSessionTemplate(SqlSessionFactory sqlSessionFactory) {
  		//防止前端不填值后端插入失败
  		sqlSessionFactory.getConfiguration().setJdbcTypeForNull(JdbcType.NULL);
  		return new SqlSessionTemplate(sqlSessionFactory);
  	}
      
      @Bean(name = "mybatisSqlSessionFactory")
      public SqlSessionFactory mybatisSqlSessionFactory(@Qualifier("mybatisDataSource") DataSource mybatisDataSource)
              throws Exception {
          final SqlSessionFactoryBean sessionFactory = new SqlSessionFactoryBean();
          sessionFactory.setDataSource(mybatisDataSource);
          sessionFactory.setMapperLocations(new PathMatchingResourcePatternResolver()
                  .getResources(DataSourceConstants.MAPPER_LOCATION));
        
          return sessionFactory.getObject();
      }
  
      public String getUrl() {
          return url;
      }
  
      public void setUrl(String url) {
          this.url = url;
      }
  
      public String getUsername() {
          return username;
      }
  
      public void setUsername(String username) {
          this.username = username;
      }
  
      public String getPassword() {
          return password;
      }
  
      public void setPassword(String password) {
          this.password = password;
      }
  
  }

  activiconfig

• @Configuration
  	public class ActivitiConfig {
  	 
  	    @Value("${spring.datasource.url}")
  	    private String url;
  	 
  	    @Value("${spring.datasource.username}")
  	    private String userName;
  	 
  	    @Value("${spring.datasource.password}")
  	    private String password;
  	 
  	    @Value("${spring.datasource.driver-class-name}")
  	    private String driver;	 	
  	 
  	    @Bean
  	    public ProcessEngineConfiguration processEngineConfiguration() {
  	        ProcessEngineConfiguration processEngineConfiguration = new StandaloneProcessEngineConfiguration();
  	        // 连接数据库的配置
  	        processEngineConfiguration.setJdbcDriver(driver);
  	        processEngineConfiguration.setJdbcUrl(url);
  	        processEngineConfiguration.setJdbcUsername(userName);
  	        processEngineConfiguration.setJdbcPassword(password);
  	       // processEngineConfiguration.setAsyncExecutorActivate(true);
  	       // processEngineConfiguration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
  	        return processEngineConfiguration;
  	    }
  	    
  	   /* @Bean
  	    public ProcessEngine processEngine() {
  	        return processEngineConfiguration().buildProcessEngine();
  	    }
  	    */
  	    @Bean
  	    public RepositoryService repositoryService() {
  	        return processEngineConfiguration().buildProcessEngine().getRepositoryService();
  	    }
  	 
  	    @Bean
  	    public RuntimeService runtimeService() {
  	        return processEngineConfiguration().buildProcessEngine().getRuntimeService();
  	    }
  	 
  	    @Bean
  	    public TaskService taskService() {
  	        return processEngineConfiguration().buildProcessEngine().getTaskService();
  	    }
  	 
  	    @Bean
  	    public FormService formService() {
  	        return processEngineConfiguration().buildProcessEngine().getFormService();
  	    }
  	 
  	    @Bean
  	    public HistoryService historyService() {
  	        return processEngineConfiguration().buildProcessEngine().getHistoryService();
  	    }
  	 
  	    @Bean
  	    public ManagementService managementService() {
  	        return processEngineConfiguration().buildProcessEngine().getManagementService();
  	    }
  	 
  	    @Bean
  	    public IdentityService identityService() {
  	        return processEngineConfiguration().buildProcessEngine().getIdentityService();
  	    }
  	}

   

• 启动类

• @SpringBootApplication
  @EnableAutoConfiguration(exclude = {     
          org.activiti.spring.boot.SecurityAutoConfiguration.class
  })
  
  public class Application {
  
  	public static void main(String[] args) {
  		SpringApplication.run(Application.class, args);
  	}

  在启动类中，一定要加上剃掉security的权限校验，不然每次需要权限校验

• 切记要在resources下创建目录processes，因为在配置文件里配置了扫描位置。

• 以上就是自己搭建的过程，搭建中坑太多了，，，，，，，
