Springboot依赖注入顺序问题

Question

最近初学Springboot,初始化图中SingInRequestProcessor类时,如何让注入的crmProperties不为null?
另外初始化时,会执行方法process内的内容,这是必然的吗?
假如crmProperties不为null,crmProperties.getKeyN()却会为空,初始化时里面还没赋值.

有相关的资料也可以给我推荐一下,谢谢了.

@Component
public class SignInRequestProcessor implements Processor {

    @Autowired
    private CRMProperties crmProperties;

    @Override public void process(Exchange exchange) throws Exception {

        //生成工作密钥,需保存
        String workKey = DES3Encrpt.newKey(16);
        crmProperties.setWorkKey(workKey);

        //signInRequest填充参数
        SignInRequest signInRequest = new SignInRequest();
        signInRequest.setRandom(String.valueOf(KunlunUtils.getRandomInt()));
        signInRequest.setClientCode(crmProperties.getClientCode());            //应从配置文件获取
        signInRequest.setWorkKey(workKey);
        signInRequest.setUserCode(crmProperties.getUserCode());
        signInRequest.setPasswd(crmProperties.getPasswd());
        signInRequest.setVerifyInfo(crmProperties.getVerifyInfo());
        signInRequest.setComputer(crmProperties.getComputer());
        signInRequest.setTerminalNo(crmProperties.getTerminalNo());

        //XML转换
        String signInRequestXML = JAXBUtils.convertObjectToXML(signInRequest);

        //RSA加密
        String psInputPara = RSAEncrpt.encrypt(signInRequestXML, crmProperties.getKeyE(), crmProperties.getKeyN());

        String content = KunlunUtils.generateSoapRequest(12, psInputPara);

        exchange.getIn().setBody(content);
    }
}

1、简单的方法：CRMProperties类上加上@Component，即可注入。

2、应该不会执行。

3、看CRMProperties中怎么处理赋值了。
