C# 通过 Hessian服务调用java

1.下载Hessiancsharp.dll

2.新建一个c#窗体程序，然后在添加一个类库

3.添加一个接口类，接口中的方法名和参数与java中的服务方法名和参数保持一致

  public partial interface HessianManager
    {
        /// <summary>
        ///
        /// </summary>
        /// <param name="method">方法名</param>
        /// <param name="operate">操作（添加、删除、修改）</param>
        /// <param name="json">json数据</param>
        /// <returns></returns>
        string synchronizeData(string method, string operate, string json);

        string sayHello(string msg);
    }

4.引用Hessiancsharp.dll

5.通过hessian调用java

    public partial class frmHessian : Form
    {
        string url = ConfigurationManager.AppSettings["url"].ToString();

        CHessianProxyFactory factory = new CHessianProxyFactory();
        HessianManager hessianClient = null;

        public frmHessian()
        {
            InitializeComponent();
            hessianClient = (HessianManager)factory.Create(typeof(HessianManager), url);
        }

        /// <summary>
        /// 同步供应商
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void btnSynSupplier_Click(object sender, EventArgs e)
        {
            List<Supplier> supplists = new List<Supplier>();
            DataTable dt = DbHelperSQL.Query("SELECT * FROM dbo.Sys_Supplier WHERE ss_State=1").Tables[0];

            foreach (DataRow item in dt.Rows)
            {
                Supplier sup = new Supplier();
                sup.bbbpSn = item["ss_SupplierNo"].ToString();
                sup.bbbpId = item["ss_SupplierNo"].ToString();
                sup.bbbpBbbrId = 1;
                sup.bbbpName = item["ss_SupplierName"].ToString();
                sup.bbbpContact = item["ss_Contact"].ToString();
                sup.bbbpContactTel = item["ss_Tel"].ToString();
                sup.bbbpContactPhone = item["ss_Phone"].ToString();
                sup.bbbpContactAddress = item["ss_Adress"].ToString();
                sup.bbbpState = Convert.ToInt32(item["ss_State"]) == 1 ? "有效" : "无效";
                sup.bbbpLocationid = 5001; //item["sp_PurchaserNo"] == DBNull.Value ? 5001 : Convert.ToInt32(item["sp_PurchaserNo"]);
                sup.bbbpYingfu = 0;
                sup.bbbpIds = ",1,";
                sup.bbbpBank = item["ss_Bank"].ToString();
                sup.bbbpBankNumber = item["ss_BankAccount"].ToString();
                sup.bbbpGongyingjiezhiDate = string.Format("{0:yyyy-MM-dd HH:mm:ss}", item["ss_BusiLicexpireTime"]);
                sup.bbbpFaxNumber = item["ss_Fax"].ToString();
                supplists.Add(sup);
            }
            string msg = hessianClient.synchronizeData("synBusinessParter", "add", JsonHelper.SerializeObject(supplists));

            Application.DoEvents();
            MessageBox.Show("同步成功！");
        }
}
