No TaskScheduler/ScheduledExecutorService bean found for scheduled processing
时间: 2023-11-04 09:58:54 浏览: 111
No TaskScheduler/ScheduledExecutorService bean found for scheduled processing是指在Spring定时任务中没有找到TaskScheduler或ScheduledExecutorService的bean。当@EnableScheduling注解启用Spring的定时任务功能时,会自动寻找TaskScheduler或ScheduledExecutorService的bean来执行定时任务。如果没有找到这些bean,会抛出No TaskScheduler/ScheduledExecutorService bean found for scheduled processing异常。
为了解决这个问题,可以按照以下步骤进行操作:
1. 确保在配置类或XML文件中已经定义了TaskScheduler或ScheduledExecutorService的bean,并且这些bean的名称为taskScheduler。
2. 如果没有特殊需求,可以直接使用默认的单线程调度器,不需要定义TaskScheduler或ScheduledExecutorService的bean。
3. 如果需要自定义调度器,可以创建一个实现了TaskScheduler或ScheduledExecutorService接口的bean,并将其定义为taskScheduler。

Field taskScheduler in gateway.confserv.conf.WebSocketConfig required a single bean, but 2 were found:
To resolve the issue of having multiple beans for the `taskScheduler` field in `gateway.confserv.conf.WebSocketConfig`, you can try the following steps:
1. Specify a qualifier for each `taskScheduler` bean in your configuration. This will help identify which bean should be injected into the `WebSocketConfig` class. For example, you can use `@Qualifier("bean1")` and `@Qualifier("bean2")`.
2. Update the `WebSocketConfig` class to use the appropriate qualifier for the `taskScheduler` field. This ensures that the correct bean is injected.
Example:
```java
@Configuration
public class WebSocketConfig {
@Autowired
@Qualifier("bean1")
private TaskScheduler taskScheduler;
// Rest of the configuration
}
```
3. Make sure that you have defined the beans with the corresponding qualifiers in your configuration class or XML file.
Example:
```java
@Configuration
public class AppConfig {
@Bean
@Qualifier("bean1")
public TaskScheduler taskSchedulerBean1() {
// Bean definition
}
@Bean
@Qualifier("bean2")
public TaskScheduler taskSchedulerBean2() {
// Bean definition
}
// Rest of the configuration
}
```
By qualifying the beans and specifying the appropriate qualifier in the `WebSocketConfig` class, you can ensure that only one bean is injected into the `taskScheduler` field.
/dolphinscheduler/projects/{projectCode}/task-definition 的用法
`/dolphinscheduler/projects/{projectCode}/task-definition` 是用于获取特定项目下的任务定义信息的 API 接口。
具体用法如下:
- 将 `{projectCode}` 替换为你想要获取任务定义信息的项目的项目编码。
- 发送 GET 请求到 `/dolphinscheduler/projects/{projectCode}/task-definition` 接口。
这个接口将返回指定项目下的任务定义信息,包括任务名称、任务类型、任务参数等。
请注意,你需要先登录并获取有效的访问令牌(access token)才能成功调用该接口。
