问题描述

我有C＃代码和一个参数化构造函数，但我想在java Web应用程序中调用参数化的构造函数。我的问题是我正在使用Javonet来传递java到.NET但是我在调​​用C＃类构造函数时它会在tomcat服务器中抛出一些异常

我尝试过：

What I have tried:

@GetMapping("/cSharpCall")
public String javaCallCsharp()
{

 final String TMP_DIR = System.getProperty("java.io.tmpdir");

    try
    {
        /*System.out.println("Setting temporary directory for Javonet lic file to: "+TMP_DIR);
        Javonet.setLicenseDirectory(TMP_DIR);*/
        if (!Javonet.isActivated())
        {
            System.out.println("Setting temporary directory for Javonet lic file to: "+TMP_DIR);
            Javonet.setLicenseDirectory(TMP_DIR);
            Javonet.activate("[e-mail]","Za2j-Hb58-z8J3-b7MA-x4J7",JavonetFramework.v45);
            System.out.println("hiii........hiii..");
        }
        Javonet.addReference("ClassLibrary.dll");
        NObject objRandom = Javonet.New("TcpipIntface.Code.Client.AcsTcpClass");

        byte b=(byte)1;
        Boolean value = objRandom.invoke("Opendoor",b);

        System.out.println(value);

    }
    catch(JavonetException e)
    {
        e.printStackTrace();

    }

    return "redirect:/customer/list";

}

推荐答案

你没有参数调用Javonet.New，所以它试图调用一个没有参数的构造函数，它不存在...

尝试这样的东西：

You call Javonet.New without parameters, so it try to invoke a parameter-less constructor, which does not exists...
Try someting like this:

Javonet.New("DateTime",1980,1,1);

你打电话给Javonet.New没有参数，所以它尝试调用一个不存在的无参数构造函数...

尝试这样的事情：

You call Javonet.New without parameters, so it try to invoke a parameter-less constructor, which does not exists...
Try something like this:

Javonet.New("DateTime",1980,1,1);
