没有类型[org.springframework.oxm.jaxb.Jaxb2Marshaller]的限定bean

Question

注入jaxb2Marshaller获取以下异常

找不到[org.springframework.oxm.jaxb.Jaxb2Marshaller]类型的限定bean用于依赖：预期至少有1个bean可以作为此依赖项的autowire候选者。依赖注释：{@ org.springframework.beans.factory.annotation.Autowired（required = true）}

@Autowired
private Jaxb2Marshaller  jaxb2Marshaller; 

public Jaxb2Marshaller getJaxb2Marshaller() {
    return jaxb2Marshaller;
}

public void setJaxb2Marshaller(Jaxb2Marshaller jaxb2Marshaller) {
    this.jaxb2Marshaller = jaxb2Marshaller;
}

getJaxb2Marshaller（）。unmarshal（new StreamSource（new ByteArrayInputStream（source.getData（）。getBytes（）））;;

任何人都可以建议如何注入jaxb2Marshaller ??
