jeesite免登陆，及vue跨域访问jeeSite项目设置

一、jeeSite 4.0以上版本
1.springMVC使用注解@CrossOrigin(origins = “*”, maxAge = 3600)

1）导入import org.springframework.web.bind.annotation.CrossOrigin;

2）方法必须声明使用什么请求方式

列如@RequestMapping(value={"/sss"},method = RequestMethod.POST)

2.jeesite框架中，需要免登录才能跨域成功

在配置文件----spring-context-shiro.xml中找到

<bean name="shiroFilterChainDefinitions" class="java.lang.String">

在需要跨域的路径中，使得 ${adminPath}/sss/** = anon

二、jeeSite 4.0版本以下
因为不存在正在@CrossOrigin
在后台写一个过滤器过滤器来改写请求头头

CorsFilter.java

public class CorsFilter implements Filter {
@Override
public void init(FilterConfig filterConfig) throws ServletException {

}

@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
    HttpServletResponse response = (HttpServletResponse) servletResponse;
    HttpServletRequest request = (HttpServletRequest)servletRequest;

    String origin = request.getHeader("Origin");
    response.setHeader("Access-Control-Allow-Origin", 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,Authorization");
    response.setHeader("Access-Control-Allow-Credentials", "true");
    String method = request.getMethod();
    if(method.equalsIgnoreCase("OPTIONS")){
        servletResponse.getOutputStream().write("Success".getBytes("utf-8"));
    }else{
        filterChain.doFilter(servletRequest, servletResponse);
    }
}

@Override
public void destroy() {

}

}
