Restful webservice 跨域问题解决

一、ajax跨域调用restful webservice

       1）jsonp的方式。略

        2）配置拦截器，设置允许那些origin可以发起跨域请求，具体代码：

public class TestInterceptor extends AbstractPhaseInterceptor {
    public TestInterceptor() {
        super(Phase.RECEIVE);
    }
 
    public TestInterceptor(String phase) {
        super(phase);
    }
 
    @Override
    public void handleMessage(Message message) throws Fault {
    	if (message.getDestination() != null) {
            System.out.println(message.getId() + "#" + message.getDestination().getMessageObserver());
        }
        if (message.getExchange() != null) {
            System.out.println(message.getExchange().getInMessage() + "#" + message.getExchange().getInFaultMessage());
            System.out.println(message.getExchange().getOutMessage() + "#" + message.getExchange().getOutFaultMessage());
        }
        HttpServletRequest request = (HttpServletRequest) message.get(  
                AbstractHTTPDestination.HTTP_REQUEST);//这句可以获取到request 
        HttpServletResponse response = (HttpServletResponse) message.get(  
                AbstractHTTPDestination.HTTP_RESPONSE);//这句可以获取到request 
        response.setCharacterEncoding("UTF-8");
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "x-requested-with");
    }
}

 

• Access-Control-Allow-Origin 为允许哪些Origin发起跨域请求. 这里设置为"*"表示允许所有。
• Access-Control-Allow-Methods 为允许请求的方法.
• Access-Control-Max-Age 表明在多少秒内，不需要再发送预检验请求，可以缓存该结果
• Access-Control-Allow-Headers 表明它允许跨域请求包含content-type头，这里设置的x-requested-with ，表示ajax请求
•  

然后在把这个拦截器加入到配置文件里面

 二、请求webservice时候，返回的数据出现中文乱码问题，我们同样可以在拦截器里面配置

response.setCharacterEncoding("UTF-8");
