7.添加基于Spring的WebService拦截器

public class AccountInterceptor extends AbstractPhaseInterceptor<SoapMessage>{

    private String name;
    private String password;
    
    public AccountInterceptor(String name,String password) {
        //Phase值决定了拦截器什么时候拦截到消息
        //PRE_PROTOCOL准备请求时拦截
        super(Phase.PRE_PROTOCOL);
        this.name = name;
        this.password = password;
    }

    //一旦被拦截，首先调用此方法
    @SuppressWarnings("deprecation")
    @Override
    public void handleMessage(SoapMessage msg) throws Fault {
        List<Header> headers = msg.getHeaders();
        //在客户端请求时，会将用户名密码带过去
        //怎么带用户名和密码到服务器，将用户名和密码设置在请求头中
        org.w3c.dom.Document document = DOMHelper.createDocument();
        Element ele = document.createElement("account");//创建标签<account></account>
        
        Element eleName = document.createElement("name");//创建标签<name></name>
        eleName.setTextContent(name);//给<name>设值，值为客户端传进来的用户名
        ele.appendChild(eleName);
        
        Element elePwd = document.createElement("password");//创建标签<password></password>
        elePwd.setTextContent(password);//给<password>设值，值为客户端传进来的密码
        ele.appendChild(elePwd);
        //设置标签<account>的account
        headers.add(new Header(new QName("account"),ele));
        //如果拦截了，打印以下信息!
        System.out.println("客户端拦截了");
    }
}
