1. 添加攔截器類AjaxFilter?

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;


/**
?*允許跨域訪問
?*/
public class AjaxFilter implements Filter {
public void destroy() {

}

public void doFilter(ServletRequest req, ServletResponse res,
FilterChain chain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) req;
HttpServletResponse response = (HttpServletResponse) res;
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,Content-Type");
chain.doFilter(request, response);
}


public void init(FilterConfig arg0) throws ServletException {
}

}

2.配置web.xml

<filter>
<filter-name>ajaxFilter</filter-name>
<filter-class>com.a.filter.AjaxFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>ajaxFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
