Camel-Spring Boot：执行后路由不会停止

Question

我正在使用 Spring Boot + Camel，配置如下。

主类

 @SpringBootApplication
public class Application extends RouteBuilder {
    public static void main(String[] args) {

        SpringApplication.run(Application.class, args);
    }
    @Override
    public void configure() throws Exception {
        from("sql:{{list.sql}}?dataSource=#dataSource")
        .log("process row ${body}")
        .to("stream:out");
    }}

application.properties

camel.springboot.name=ListJob
camel.springboot.main-run-controller=true

list.sql=<SELECT QUERY>

spring.datasource.driver=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://IP:3306/test
spring.datasource.username=un
spring.datasource.password=pwd

由于 "camel.springboot.main-run-controller" 属性，我的 Spring Boot 在执行 SELECT 查询的无限循环中运行路由，直到我点击 CNTRL+C。如果我删除此属性，应用程序只会立即启动和停止路由，而不会完成执行。

有人可以帮我，让我的路线开始，执行步骤并在我运行 Spring Boot 应用程序时停止吗？

Answer 1

您可以使用 spring-boot 属性：

# handle only one 1 message and then stop the route
camel.springboot.duration-max-messages=1
# run for 180 seconds and then gracefully shutdown
camel.springboot.duration-max-seconds=180
# a polling consumer will cancel the graceful shutdown so set the shutdownTimeout to a minimum
camel.springboot.shutdownTimeout=1

Answer 2

添加.stop()：

public void configure() throws Exception {
        from("sql:{{list.sql}}?dataSource=#dataSource")
        .log("process row ${body}")
        .stop();
    }
