【Java】Springboot依赖注入顺序问题

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);
}}
