Spring：XML配置轉換為Java配置

Question

我在項目中使用activiti和spring，以前以如下方式配置的XML方式：

<bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService" />
<bean id="runtimeService" factory-bean="processEngine" factory-method="getRuntimeService" />
<bean id="taskService" factory-bean="processEngine" factory-method="getTaskService" />
<bean id="historyService" factory-bean="processEngine" factory-method="getHistoryService" />
<bean id="managementService" factory-bean="processEngine" factory-method="getManagementService" />

如何配置為轉換為JAVA？

Answer 1

像這樣：

@Autowired
@Bean(name = "repositoryService"
RepositoryService createRepositoryService(ProcessEngine processEngine) {
    return processEngine.getRepositoryService();
}
