spring mvc静态资源权限访问的设置方式_Java

一、案例现象

1.controller层

  /**
     * @author liujianfu
     * @description      controller中业务方法的集合参数获取，要将集合参数封装到一个pojo中才可以
     * 参数属性名与请求参数名称一致，参数值会自动映射匹配
     * @date 2021/1/10 22:14
     * @param
     * @return
     */
    @requestmapping("/bike6")
    public string bike6(){
      system.out.println("controller6:");
        return "ajax";
    }
    /**
     * @author liujianfu
     * @description      controller中业务方法的集合参数获取，要将集合参数封装到一个pojo中才可以
     * 参数属性名与请求参数名称一致，参数值会自动映射匹配
     * @date 2021/1/10 22:14
     * @param
     * @return
     */
    @requestmapping("/bike7")
    @responsebody
    public string bike7(@requestbody list<user> userlist){
        for(user u:userlist){
            system.out.println("user:"+u.getusername());
        }
        return "ok";
    }

2.jsp页面

<%@ page contenttype="text/html;charset=utf-8" language="java" %>
<html>
<head>
    <title>title</title>
    <script src="${pagecontext.request.contextpath}/js/jquery.min.js"></script>
    <script>
        var userlist=new array();
        userlist.push({username:"beijing",age:34});
        userlist.push({username:"shanghai",age:89});
        $.ajax({
            type:"post",
            url:"${pagecontext.request.contextpath}/bike7",
            data:json.stringify(userlist),
            contenttype:"application/json;charset=utf-8",
            success:function(result){
                alert(result);
            }
        })
    </script>
</head>
<body>

</body>
</html>

3.重启服务进行访问

二、解决办法

2.1 在spring-mvc 配置文件中，设置开放静态资源的访问

    <mvc:resources mapping="/js/**" location="/js/"></mvc:resources>
    <mvc:resources mapping="/images/**" location="/images/"></mvc:resources>
    <mvc:resources mapping="/css/**" location="/css/"></mvc:resources>
