Jax-ws 开发webService ，并使用spring注入service类中遇到 空指针

               

一般情况下，使用eclipse自带的 jax-ws 生成webservice 会自动生成2个类：

ContractConnector.java

ContractConnectorDelegate.java

package com.wonders.webservice.contract;@javax.jws.WebService(targetNamespace = "http://contract.webservice.wonders.com/", serviceName = "ContractConnectorService", portName = "ContractConnectorPort", wsdlLocation = "WEB-INF/wsdl/ContractConnectorService.wsdl")public class ContractConnectorDelegate { com.wonders.webservice.contract.ContractConnector contractConnector = new com.wonders.webservice.contract.ContractConnector(); public String saveContract(String contractXML, String secret) {  return contractConnector.saveContract(contractXML, secret); }}

ContractConnector中
ContractWsService该类中包含了存取数据及对hibernate 的使用，所以使用spring注入，但webservice调用时，一直抱空指针。

由于ContractConnectorDelegate类中 需要new ContractConnector类 ，所以无法注入service

故最后将service修改为static 后，程序启动就注入，这样new 了之后，该service 存在。
