如何整合Spring Boot，Camel和Mybatis

问题描述

需要使用SpringBoot将Camel和MyBatis与应用程序集成在一起.SpringBoot为Camel和MyBatis提供了开箱即用的支持.还提供了Camel和MyBatis SpringBoot启动器.

Need to Integrate Camel and MyBatis with application using SpringBoot.SpringBoot provides out-of-box support for Camel and MyBatis. Also provides Camel and MyBatis SpringBoot starters.

但是，当我尝试将Spring Boot应用程序与Camel和MyBatis集成时，它会失败.

However, when i try to integrate Spring Boot application with Camel and MyBatis, it fails.

我正在使用基于Java DSL的Camel Route.还使用Mybatis Spring启动依赖项.注释映射器，在application.properties文件中添加数据库属性.我期望发生的事情:1)SpringBoot设置数据源和映射器，启动时使用sqlsessionfactory.2)接下来调用Camel-MyBatis使用者，在(1)中完成的设置将允许Camel使用mybatis成功进行数据库调用.

I am using Java DSL based Camel Route. Also using Mybatis Spring boot dependencies. Annotate mappers, added database properties in the application.properties file. What I was expecting to happen:1) SpringBoot setup datasource and mappers, sqlsessionfactory on start-up.2) Next the Camel-MyBatis consumer is called, the setup done in (1) would allow, Camel to successfully make database calls using mybatis.

我创建了带弹簧注释的配置类，并用它来创建/获取DataSource bean.

I created spring annotated configuration class and used it to create/get DataSource bean.

我如何让骆驼使用此dataSource bean?如何告诉Camel使用新构建的SQL会话工厂，而不是尝试从配置文件构建?

How can i get Camel to use this dataSource bean?How to tell Camel to use newly build SQL session factory, instead of it trying to build from configuration file?

在github中创建了示例应用，它使用内存中的数据库(h2)

推荐答案

我已经能够成功将Spring Boot 1.3.6，Apache Camel 2.17.2与Mybatis-Spring-Boot-Starter 1.1.1结合使用:

I have been able to use Spring Boot 1.3.6, Apache Camel 2.17.2 with Mybatis-Spring-Boot-Starter 1.1.1 successfully:

maven中的关键依赖项:

Key dependencies in maven:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-spring-boot-starter</artifactId>
</dependency>
<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-mybatis</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-spring-boot</artifactId>
</dependency>

要声明的关键豆

@Bean(name="mybatis")
public MyBatisComponent myBatisComponent( SqlSessionFactory sqlSessionFactory )
{
    MyBatisComponent result = new MyBatisComponent();
    result.setSqlSessionFactory( sqlSessionFactory );
    return result;
}
