[游戏开发]Whitelabel Error PageThis application has no explicit mapping for /error so you are seeing this as

        private String userName;
        private  Integer age;
//    public UserEntity(){
//
//    }


        public UserEntity(String userName,Integer age){
            this.userName=userName;
            this.age=age;

        }

在上面这段代码块中没有设置无参构造会在网页中出现出现

There was an unexpected error (type=Internal Server Error, status=500).

nested exception is org.apache.ibatis.executor.ExecutorException: No constructor found in com.mayikt.Entity.UserEntity matching [java.lang.Integer, java.lang.String]

解决方法

只需在方法类中添加无参构造即可
