SpringBoot整合Flowable6.4

大量的配置文件让人很烦躁，尤其是某个项目中无处不在却怎么也找不到的配置文件，所以之前的示例项目也是时候改成SpringBoot了。

基于上一篇的示例，首先在Pom文件中新增加DataSource、Flowable和其它一些将要用到的配置：

<!-- datasource -->
<dependency>
  <groupId>mysql</groupId>
  <artifactId>mysql-connector-java</artifactId>
  <version>5.1.38</version>
</dependency>
<dependency>
  <groupId>com.alibaba</groupId>
  <artifactId>druid</artifactId>
  <version>1.1.2</version>
</dependency>
<!-- flowable -->
<dependency>
  <groupId>org.flowable</groupId>
  <artifactId>flowable-spring-boot-starter-process</artifactId>
  <version>6.4.1</version>
</dependency>
<dependency>
  <groupId>org.flowable</groupId>
  <artifactId>flowable-json-converter</artifactId>
  <version>6.4.1</version>
</dependency>
<!-- hutool -->
<dependency>
  <groupId>cn.hutool</groupId>
  <artifactId>hutool-core</artifactId>
  <version>4.6.1</version>
</dependency>
<dependency>
  <groupId>commons-io</groupId>
  <artifactId>commons-io</artifactId>
  <version>2.4</version>
</dependency>

然后，配置DataSource：

@Configuration
@EnableTransactionManagement
public class DataSourceConfig {

    @Primary
    @Bean(name = "dataSource")
    @ConditionalOnBean(PropertiesConfigurer.class)
    public DataSource getDataSource() throws Exception {
        DruidDataSource dataSource = new DruidDataSource();
        //PropertiesConfigurer是一个获得配置文件属性的持久类
        dataSource.setDriverClassName(PropertiesConfigurer.getProperty("db.driver"));
        dataSource.setUrl(PropertiesConfigurer.getProperty("db.url"));
        dataSource.setUsername(PropertiesConfigurer.getProperty("db.user"));
        dataSource.setPassword(PropertiesConfigurer.getProperty("db.password"));
        dataSource.setInitialSize(1);
        dataSource.setMinIdle(1);
        dataSource.setMaxActive(20);
        dataSource.setFilters("stat");
        return dataSource;
    }

    @Primary
    @Bean(name = "transactionManager")
    public DataSourceTransactionManager getDataSourceTransactionManager(@Qualifier("dataSource")DataSource dataSource) {
        DataSourceTransactionManager dataSourceTransactionManager = new DataSourceTransactionManager();
        dataSourceTransactionManager.setDataSource(dataSource);
        return dataSourceTransactionManager;
    }
}

配置Flowable：

@Configuration
public class FlowableConfig {

    @Primary
    @Bean(name = "processEngineConfiguration")
    public SpringProcessEngineConfiguration getSpringProcessEngineConfiguration(@Qualifier("dataSource") DataSource dataSource, @Qualifier("transactionManager")DataSourceTransactionManager transactionManager) {
        SpringProcessEngineConfiguration configuration = new SpringProcessEngineConfiguration();
        configuration.setDataSource(dataSource);
        configuration.setTransactionManager(transactionManager);
        configuration.setDatabaseSchemaUpdate("true");
        configuration.setAsyncExecutorActivate(true);
        configuration.setCustomPostDeployers(new ArrayList<EngineDeployer>(){
            private static final long serialVersionUID = 4041439225480991716L;
            {
                add(new RulesDeployer());
            }
        });
        return configuration;
    }
}
