Jax-ws 开发webService ，并使用spring注入service类中遇到 空指针
作者：互联网
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
package com.wonders.webservice.contract;
import java.text.DecimalFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;

import com.wonders.webservice.contract.service.ContractWsService;
public class ContractConnector {
public ContractConnector() {
System.out.println("初始化connecter");
}
private static ContractWsService contractWsService;
public void setContractWsService(ContractWsService contractWsService) {
this.contractWsService = contractWsService;
}
public String saveContract(String contractXML,String secret){
if(secret==null || !"abcd".equals(secret)){
return "验证码错误！";
}
try {
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
ContractWs contractWs = new ContractWs(); //存到临时表中去
Document document = DocumentHelper.parseText(contractXML);
Element root = document.getRootElement();
/**必填区域**/

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。
