Activiti7支持达梦数据库

国产化是大势所趋，这里尝试一下达梦数据库

1. 引入达梦数据库连接驱动包

驱动jar—DmJdbcDriver18.jar，可将该jar包上传至阿里云私有maven仓库，并通过maven下载引入。

<dependency>
    <groupId>com.dameng</groupId>
    <artifactId>DmJdbcDriver18</artifactId>
    <version>8.1.1.193</version>
</dependency>

2. 配置数据库连接

在application.yml中添加如下内容：

spring:
 datasource:
  username: ACTIVITI
  password: 123456789
  jdbc-url: jdbc:dm://192.168.1.39:5236:DAMENG
driver-class-name: dm.jdbc.driver.DmDriver

3. 更改Activiti 默认数据源连接方式

因为Activiti 包中未预设达梦数据库，所以要手动修改默认数据源连接方式。方法为增加类ActivitiConfig，在类中重新定义activiti的配置类SpringProcessEngineConfiguration。

import org.activiti.spring.SpringProcessEngineConfiguration;
import org.activiti.spring.boot.AbstractProcessEngineAutoConfiguration;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.jdbc.DataSourceBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.transaction.PlatformTransactionManager;

import javax.annotation.Resource;
import javax.sql.DataSource;

//声名为配置类，继承Activiti抽象配置类
@Configuration
public class ActivitiConfig extends AbstractProcessEngineAutoConfiguration {

    @Bean
    @Primary
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource activitiDataSource() {
        return DataSourceBuilder.create().build();
    }

    @Resource
    PlatformTransactionManager activitiTransactionManager;


    @Bean
    public SpringProcessEngineConfiguration springProcessEngineConfiguration(){
        System.out.println("注入activiti的config");
        SpringProcessEngineConfiguration configuration = new SpringProcessEngineConfiguration();
         DataSource dataSource = activitiDataSource();
         configuration.setDataSource(dataSource);
         configuration.setDatabaseType("oracle");
         configuration.setTransactionManager(activitiTransactionManager);
         configuration.setDatabaseSchemaUpdate("none");
        return  configuration;
    }
}

4. 初始化Activiti 所需的表

达梦数据库与oracle兼容，所以可直接执行activiti的oracle的初始sql。

sql语句activiti.oracle.create.engine.sql

5. 修正缺失字段

官方初始化sql中缺少ACT_RE_DEPLOYMENT表的PROJECT_RELEASE_VERSION_和VERSION_字段，可执行下列sql语句进行增加。

alter table ACT_RE_DEPLOYMENT add column PROJECT_RELEASE_VERSION_ varchar(255) DEFAULT NULL;
alter table ACT_RE_DEPLOYMENT add column VERSION_ varchar(255) DEFAULT NULL;
