1|1簡(jiǎn)介

最近基于最新的Activiti7配置了SpringBoot2。

簡(jiǎn)單上手使用了一番。發(fā)現(xiàn)市面上解決Activiti7的教程很少，采坑也比較多，在A(yíng)ctiviti6配置數(shù)據(jù)源和Activiti7有所區(qū)別，基于A(yíng)ctiviti6在A(yíng)ctiviti7里是無(wú)法正常使用的。接下來(lái)讓我們看下區(qū)別。

1|2問(wèn)題

Activiti6多數(shù)據(jù)源配置

6的配置比較簡(jiǎn)單點(diǎn)。

先加入配置：

# activiti 數(shù)據(jù)源spring.datasource.activiti.driver=com.MySQL.jdbc.Driverspring.datasource.activiti.url=jdbc:mysql://10.1.1.97:3311/test-activiti7-db?useUnicode=true&characterEncoding=utf8&useSSL=false&allowMultiQueries=truespring.datasource.activiti.username=rootspring.datasource.activiti.password=Rtqw123OpnmERspring.datasource.activiti.driverClassName=com.mysql.jdbc.Driver

用@ConfigurationProperties加載以spring.datasource.activiti開(kāi)頭的DataSource。創(chuàng)建ActivitiConfig繼承AbstractProcessEngineAutoConfiguration方法注入SpringProcessEngineConfigurationbean,調(diào)用AbstractProcessEngineAutoConfiguration#baseSpringProcessEngineConfiguration方法把創(chuàng)建的數(shù)據(jù)源注入。

Activiti6的數(shù)據(jù)源已經(jīng)配置完成，如果是7的話(huà)會(huì)發(fā)現(xiàn)

AbstractProcessEngineAutoConfiguration#baseSpringProcessEngineConfiguration方法已經(jīng)不存在了，我們需要產(chǎn)考源碼構(gòu)建方式改造一番。

1|3修復(fù)

Activiti7多數(shù)據(jù)源配置

配置還是要上面的。

創(chuàng)建ActivitiConfig繼承AbstractProcessEngineAutoConfiguration方法注入SpringProcessEngineConfigurationbean。用@ConfigurationProperties加載以spring.datasource.activiti開(kāi)頭的DataSource

@Configurationpublic class ActivitiConfig extends AbstractProcessEngineAutoConfiguration { @Bean @ConfigurationProperties(prefix = "spring.datasource.activiti") public DataSource activitiDataSource() { return DataSourceBuilder.create().build(); } ...略}SpringProcessEngineConfiguration注入方式改為下面： @Bean @Primary public SpringProcessEngineConfiguration springProcessEngineConfiguration( PlatformTransactionManager transactionManager, SpringAsyncExecutor springAsyncExecutor, ActivitiProperties activitiProperties, ProcessDefinitionResourceFinder processDefinitionResourceFinder, @Autowired(required = false) DefaultActivityBehaviorFactoryMappingConfigurer processEngineConfigurationConfigurer, @Autowired(required = false) List<ProcessEngineConfigurator> processEngineConfigurators, UserGroupManager userGroupManager, DataSource dataSource) throws IOException { SpringProcessEngineConfiguration conf = new SpringProcessEngineConfiguration(); conf.setConfigurators(processEngineConfigurators); configureProcessDefinitionResources(processDefinitionResourceFinder, conf); conf.setDataSource(dataSource); conf.setTransactionManager(transactionManager); if (springAsyncExecutor != null) { conf.setAsyncExecutor(springAsyncExecutor); } conf.setDeploymentName(activitiProperties.getDeploymentName()); conf.setDatabaseSchema(activitiProperties.getDatabaseSchema()); conf.setDatabaseSchemaUpdate(activitiProperties.getDatabaseSchemaUpdate()); conf.setDbHistoryUsed(activitiProperties.isDbHistoryUsed()); conf.setAsyncExecutorActivate(activitiProperties.isAsyncExecutorActivate()); if (!activitiProperties.isAsyncExecutorActivate()) { ValidatorSet springBootStarterValidatorSet = new ValidatorSet("activiti-spring-boot-starter"); springBootStarterValidatorSet.addValidator(new AsyncPropertyValidator()); if (conf.getProcessValidator() == null) { ProcessValidatorImpl processValidator = new ProcessValidatorImpl(); processValidator.addValidatorSet(springBootStarterValidatorSet); conf.setProcessValidator(processValidator); } else { conf.getProcessValidator().getValidatorSets().add(springBootStarterValidatorSet); } } conf.setMailServerHost(activitiProperties.getMailServerHost()); conf.setMailServerPort(activitiProperties.getMailServerPort()); conf.setMailServerUsername(activitiProperties.getMailServerUserName()); conf.setMailServerPassword(activitiProperties.getMailServerPassword()); conf.setMailServerDefaultFrom(activitiProperties.getMailServerDefaultFrom()); conf.setMailServerUseSSL(activitiProperties.isMailServerUseSsl()); conf.setMailServerUseTLS(activitiProperties.isMailServerUseTls()); if (userGroupManager != null) { conf.setUserGroupManager(userGroupManager); } conf.setHistoryLevel(activitiProperties.getHistoryLevel()); conf.setCopyVariablesToLocalForTasks(activitiProperties.isCopyVariablesToLocalForTasks()); conf.setSerializePOJOsInVariablesToJson(activitiProperties.isSerializePOJOsInVariablesToJson()); conf.setJavaClassFieldForJackson(activitiProperties.getJavaClassFieldForJackson()); if (activitiProperties.getCustomMybatisMappers() != null) { conf.setCustomMybatisMappers( getCustomMybatisMapperClasses(activitiProperties.getCustomMybatisMappers())); } if (activitiProperties.getCustomMybatisXMLMappers() != null) { conf.setCustomMybatisXMLMappers( new HashSet<>(activitiProperties.getCustomMybatisXMLMappers())); } if (activitiProperties.getCustomMybatisXMLMappers() != null) { conf.setCustomMybatisXMLMappers( new HashSet<>(activitiProperties.getCustomMybatisXMLMappers())); } if (activitiProperties.isUseStrongUuids()) { conf.setIdGenerator(new StrongUuidGenerator()); } if (activitiProperties.getDeploymentMode() != null) { conf.setDeploymentMode(activitiProperties.getDeploymentMode()); } conf.setActivityBehaviorFactory(new DefaultActivityBehaviorFactory()); if (processEngineConfigurationConfigurer != null) { processEngineConfigurationConfigurer.configure(conf); } return conf; } private void configureProcessDefinitionResources( ProcessDefinitionResourceFinder processDefinitionResourceFinder, SpringProcessEngineConfiguration conf) throws IOException { List<Resource> procDefResources = processDefinitionResourceFinder .discoverProcessDefinitionResources(); if (!procDefResources.isEmpty()) { conf.setDeploymentResources(procDefResources.toArray(new Resource[0])); } }

1|4常見(jiàn)錯(cuò)誤

在以上配置中可能會(huì)有jdbcUrl is required with driverClassName錯(cuò)誤

解決辦法如下:

# activiti 數(shù)據(jù)源spring.datasource.activiti.driver=com.mysql.jdbc.Driverspring.datasource.activiti.url=jdbc:mysql://10.1.1.97:3311/test-activiti7-db?useUnicode=true&characterEncoding=utf8&useSSL=false&allowMultiQueries=true# url換為jdbc-url 解決jdbcUrl is required with driverClassName錯(cuò)誤# 官方文檔的解釋是：# 因?yàn)檫B接池的實(shí)際類(lèi)型沒(méi)有被公開(kāi)，所以在您的自定義數(shù)據(jù)源的元數(shù)據(jù)中沒(méi)有生成密鑰，而且在IDE中沒(méi)有完成(因?yàn)镈ataSource接口沒(méi)有暴露屬性)。# 另外，如果您碰巧在類(lèi)路徑上有Hikari，那么這個(gè)基本設(shè)置就不起作用了，因?yàn)镠ikari沒(méi)有url屬性(但是確實(shí)有一個(gè)jdbcUrl屬性)。在這種情況下，您必須重寫(xiě)您的配置如下:spring.datasource.activiti.jdbc-url=${spring.datasource.activiti.url}spring.datasource.activiti.username=rootspring.datasource.activiti.password=Rtqw123OpnmERspring.datasource.activiti.driverClassName=com.mysql.jdbc.Driver
