Spring boot Spring Boot Camel JPA没有要加入的本地事务

我正在使用

Spring Boot 1.5.10.RELEASE
Camel 2.21.1
Java 1.8

我的申请

@SpringBootApplication
@ImportResource({"classpath:my-webservice.xml", "classpath:my-camel.xml"})
public class CamelCXFApplication extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(CamelCXFApplication.class, args);
    }

    @Bean
    ServletRegistrationBean servletRegistrationBean() {
        ServletRegistrationBean servlet = new ServletRegistrationBean(new CamelHttpTransportServlet(), "/camel-rest-jpa/*");
        servlet.setName("CamelServlet");
        return servlet;
    }
}

我的路线

@Component
public class RestAPI extends RouteBuilder {

    @Override
    public void configure() {
        restConfiguration().contextPath("/camel-rest-jpa").apiContextPath("/api-doc")
                .apiProperty("api.title", "Camel REST API")
                .apiProperty("api.version", "1.0")
                .apiProperty("cors", "true")
                .apiContextRouteId("doc-api")
                .bindingMode(RestBindingMode.json);


        rest("/books").description("Books REST service")
                .get("/").description("The list of all the books")
                .route().routeId("books-api")
                .bean(Database.class, "findBooks")
                .endRest()
                .get("order/{id}").description("Details of an order by id")
                .route().routeId("order-api")
                .bean(Database.class, "findOrder(${header.id})");


    }
}

我的后路

@Component
public class Backend extends RouteBuilder {

    @Override
    public void configure() {


        // A first route generates some orders and queue them in DB
        from("timer:new-order?delay=1s&period={{example.generateOrderPeriod:2s}}")
                .routeId("generate-order")
                .bean("orderService", "generateOrder")
                .to("jpa:org.apache.jms.example.spring.boot.rest.jpa.Order")
                .log("Inserted new order ${body.id}");

        // A second route polls the DB for new orders and processes them
        from("jpa:org.apache.jms.example.spring.boot.rest.jpa.Order"
                + "?consumer.namedQuery=new-orders"
                + "&consumer.delay={{example.processOrderPeriod:5s}}"
                + "&consumeDelete=false")
                .routeId("process-order")
                .log("Processed order #id ${body.id} with ${body.amount} copies of the «${body.book.description}» book");

    }
}

马文

我正在跟踪

https://github.com/apache/camel/tree/master/examples/camel-example-spring-boot-rest-jpa

但是我没有使用Spring Boot 2.0.3，我使用的是1.5.10

更新

我意识到我有一个

jmtransactionmanager

@Bean
    public JmsTransactionManager jmsTransactionManager(final ConnectionFactory connectionFactory) {
        JmsTransactionManager jmsTransactionManager = new JmsTransactionManager();
        jmsTransactionManager.setConnectionFactory(connectionFactory);
        return jmsTransactionManager;
    }

---

我是否需要为Jpa定义其他transactionManager？还需要什么？

要集成数据库并将其用于事务性应用，您的

JmsTransactionManager

不适合。您需要一个

DataSourceTransactionManager

我没有看到任何发送或使用JMS的路由。如果您根本不使用JMS，那么就不需要

JmsTransactionManager
