activiti怎么把xml配置形式变为java config 形式

[阿侬呀]

@Bean
public SpringProcessEngineConfiguration springProcessEngineConfiguration(DruidDataSource druidDataSource,HibernateTransactionManager hibernateTransactionManager){
SpringProcessEngineConfiguration springProcessEngineConfiguration =new SpringProcessEngineConfiguration();
springProcessEngineConfiguration.setDataSource(druidDataSource());
springProcessEngineConfiguration.setTransactionManager(hibernateTransactionManager);

//springProcessEngineConfiguration.setDatabaseSchemaUpdate(databaseSchemaUpdate);
springProcessEngineConfiguration.setJobExecutorActivate(false);
return springProcessEngineConfiguration;
}
// <bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean">
// <property name="processEngineConfiguration" ref="processEngineConfiguration" />
// </bean>
@Bean
public ProcessEngineFactoryBean processEngineFactoryBean(SpringProcessEngineConfiguration springProcessEngineConfiguration){
ProcessEngineFactoryBean processEngineFactoryBean = new ProcessEngineFactoryBean();
processEngineFactoryBean.setProcessEngineConfiguration(springProcessEngineConfiguration);

return processEngineFactoryBean;
}
@Bean
public ProcessEngine processEngine() {
ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
processEngine.getRepositoryService();
processEngine.getRuntimeService();
processEngine.getTaskService();
processEngine.getHistoryService();
processEngine.getIdentityService();
processEngine.getManagementService();

return processEngine;
}
