写一个不用配置文件的springmvc拦截器，用于拦截所有/jftzc/*，拦截到的请求需从请求头中获取参数uid，当uid=12345时放行，否则返回401.

public class MyInterceptor implements HandlerInterceptor {

@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
String requestUri = request.getRequestURI();
if (requestUri.startsWith("/jftzc/")) {
String uid = request.getHeader("uid");
if ("12345".equals(uid)) {
return true;
} else {
response.setStatus(HttpStatus.UNAUTHORIZED.value());
return false;
}
}
return true;
}

}

写一个springmvc拦截器，用于拦截所有/jftzc/*，拦截到的请求需从请求头中获取参数uid，当uid=12345时放行，否则返回401.

public class MyInterceptor implements HandlerInterceptor {

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        String uri = request.getRequestURI();
        if (uri.startsWith("/jftzc/")) {
            String uid = request.getHeader("uid");
            if ("12345".equals(uid)) {
                return true;
            } else {
                response.setStatus(401);
                return false;
            }
        }
        return true;
    }
}

需要在Spring MVC配置文件中注册该拦截器：

<mvc:interceptors>
    <mvc:interceptor>
        <mvc:mapping path="/jftzc/**"/>
        <bean class="com.example.MyInterceptor"/>
    </mvc:interceptor>
</mvc:interceptors>
