网上的解决办法:

文献1:https://www.cnblogs.com/xiaotiannet/p/3846966.html
他里面提到的方法我感觉是c#或者.net的方法,我在java里面没有找到相应的包。需要用using Oracle.DataAccess.Types;
using Oracle.DataAccess.Client;类似这种
https://blog.csdn.net/studyzy/article/details/11524527
无奈放弃。

文献2:https://blog.csdn.net/WangJQ12/article/details/78772311
使用mybatis的框架,但是工会的框架不是mybatis,不能用。放弃

文献3:https://blog.csdn.net/qiruiduni/article/details/37882031
这种方法应该是比较通用的,但是我意外的发现其实什么都不用加,就可以插入了。所以也没有用到。

最终的解决办法:

最开始是想用文献2的方法,但是gh的框架,不允许,只能自己实现一个controller了,本来想用拦截器,但是框架里面找不到bean的配置地方,用filter也行,但是我觉得有点麻烦,偶然发现了rdcp.request然后就用了controller

补充:

关于发布的问题,
1.本来我添加了一个java文件,我觉得应该改一下class,但是我查看了out目录,并没有发现class文件,就算我手动编译我也不知道放在哪里,后来我意外的发现,直接把java文件放上去,然后成了,也就是说不需要编译 连重启都不需要

2.另外就是数据库连接格式的问题,官网用的是oracle 12 本地用的是 oracle 11 ,发现后台报错,查看了下怀疑是 url的格式好像有点区别,其他都不变,需要改下url
private static String URL = “jdbc:oracle:thin:@xxx:1521:orcl”;(本地和远程都可以)

核心代码如下:

jsp

    var CUR_USER_ID= $("#CUR_USER_ID").val();
            rdcp.request("!gh/manu/~java/Dbjz_manu.dbjzApply",{"manu_id":manu_id,"company":company,"CUR_USER_ID":CUR_USER_ID,"content":content,"author_one":author_one,"author_two":author_two,"author_three":author_three,"content_text":text},function(data){
                if(data.header.code == 0)
                {
                    $.messager.alert("提示","插入成功!","info",function () {
                        cancel();

                    });
                }
            });

        }
