如何在xml中定义的骆驼路线中使用spring bean

问题描述 投票：0回答：1

问题是关于在xml文件中定义的在骆驼路线中使用由mapstruct产生的Spring bean /我有以下配置：春季java

@Component
public class OrderMapperImpl implements OrderMapper {

    @Override
    public CreateOrderRequest map(Order value) {
    }
}

@Bean
public Jaxb2Marshaller jaxbUnmarshaller() {
    Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
    marshaller.setPackagesToScan("ru.sth.package");
    return marshaller;
    }

骆驼xml路由

<?xml version="1.0" encoding="UTF-8"?>
<routes>
...
    <route id="from_somewhere">
        <from uri="{{random.endpoint}}"/>
        <log message="Received message from ${body}"/>
        <to uri="bean:jaxbUnmarshaller?method=unmarshal"/>
        <to uri="bean:orderMapper?method=map"/>
        <to uri="direct:toSomewhere" pattern="InOut"/>
    </route>
...
</routes>

例外是

有趣的是，解组器一切正常。映射器也是由mapstruct生成的，并在编译时生成有任何想法吗？

spring routes apache-camel spring-bean mapstruct

Spring组件扫描将创建的bean是OrderMapperImpl。在Spring中，默认情况下，带注释的Bean的名称是从类的简单名称生成的，并带有小写的首字母。

因此，在您的情况下，bean的名称为orderMapperImpl，应在骆驼xml定义中使用该名称。
