项目搭建

• 使用IDE或者在http://start.spring.io上创建一个SpringBoot的基础项目，差不多是这样的目录结构
  
• 引入相关依赖

<!-- activiti -->
<dependency>
	<groupId>org.activiti</groupId>
	<artifactId>activiti-spring-boot-starter-basic</artifactId>
	<version>${activiti.version}</version>
</dependency>

<dependency>
	<groupId>org.activiti</groupId>
	<artifactId>activiti-modeler</artifactId>
	<version>${activiti.version}</version>
</dependency>

<dependency>
	<groupId>org.activiti</groupId>
	<artifactId>activiti-diagram-rest</artifactId>
	<version>${activiti.version}</version>
</dependency>

<!-- db -->
<dependency>
	<groupId>mysql</groupId>
	<artifactId>mysql-connector-java</artifactId>
</dependency>

<dependency>
	<groupId>org.mybatis.spring.boot</groupId>
	<artifactId>mybatis-spring-boot-starter</artifactId>
	<version>1.3.0</version>
</dependency>

<dependency>
	<groupId>com.github.drtrang</groupId>
	<artifactId>druid-spring-boot-starter</artifactId>
	<version>1.0.2</version>
</dependency>

<dependency>
	<groupId>com.baomidou</groupId>
	<artifactId>mybatisplus-spring-boot-starter</artifactId>
	<version>1.0.4</version>
</dependency>**

这样基本的东西也就差不多了

配置activiti

• 我这里将application.properties改成了yml格式(个人比较喜欢吧)，配置文件如下：

spring:
  application:
    name: spring-boot-activiti
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/activiti_learning?useUnicode=true&characterEncoding=utf8
    username: root
    password: 
    druid:
      validationQuery: SELECT 1
      initialSize: 10
      minIdle: 10
      maxActive: 200
      minEvictableIdleTimeMillis: 180000
      testOnBorrow: false
      testWhileIdle: true
      removeAbandoned: true
      removeAbandonedTimeout: 1800
      logAbandoned: true
      poolPreparedStatements: true
      maxOpenPreparedStatements: 100
  activiti:
    check-process-definitions: false
  mvc:
    static-path-pattern: /**
security:
  basic:
    enabled: false
server:
  port: 6000
mybatis-plus:
  mapper-locations: classpath:mapper/*Mapper.xml
  typeAliasesPackage: com.xiaoantimes.taichi.entity
  global-config:
    id-type: 2
    field-strategy: 2
    auto-set-db-type: true
    db-column-underline: true
    refresh-mapper: true
  configuration:
    map-underscore-to-camel-case: true
    cache-enabled: false

• 配置activiti的SpringProcessEngineConfiguration

@Configuration
public class ActivitiConfig {

  @Autowired
  PlatformTransactionManager transactionManager;

  @Autowired
  DruidDataSource druidDataSource;

  @Bean
  public SpringProcessEngineConfiguration getProcessEngineConfiguration(){
      SpringProcessEngineConfiguration config =  
						     new SpringProcessEngineConfiguration();
      config.setDataSource(druidDataSource);
      config.setTransactionManager(transactionManager);
      config.setDatabaseType("mysql");
      config.setDatabaseSchemaUpdate("true");
      return config;
  }
}

到这里SpringBoot已经集成好了Activiti

启动

我们启动我们到程序，这时候，你可以在数据库中看到生成了Activiti相关到表，说明我们集成成功了

问题

• 看到有的人是在配置的时候，还配置了八大接口，其实不需要，用起步依赖，这些都不需要我们来做了，需要用的时候直接注入就行
