我无法使用 JDBC 驱动程序在 Java 中使用 SOAP Web 服务在 MYSQL 中插入

I can't make an Insert in MYSQL with a SOAP web service in Java using JDBC driver

您好,我正在尝试测试连接到 mysql 本地主机 (xampp) 的 Web 服务 Soap java,但我无法在数据库中插入任何行 这是我的代码

Conexion.java

import java.sql.Connection
import java.sql.DriverManager

public class Conexion {

public static final Connection ConectarMySQL() throws SQLException
{
    Connection conn;
    try
    {          
        conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/controldecalidad", "root", "");            
    }
    catch(SQLException ex)
    {
        throw new SQLException(ex.getMessage());
    }
    return conn;
}

}

这是网络服务

 @WebMethod(operationName= "registra_rechazo")   
public void registra_rechazo(@WebParam(name = "SKU")String SKU,@WebParam(name = "fecha")String fecha,
        @WebParam(name = "num_captura")String num_captura,@WebParam(name = "pesoCaptura") int pesoCaptura) 
{
    try
    {
        Connection conn = Conexion.ConectarMySQL();
        String sql = "INSERT INTO registra_rechazo VALUES(?,?,?,?)";
        PreparedStatement pst = conn.prepareStatement(sql);
        pst.setString(1, SKU);   
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-mm-dd");            
        pst.setString(2, dateFormat.format(fecha));
        pst.setString(3, num_captura);
        pst.setInt(4, pesoCaptura);
        pst.execute();
        pst.close();
        conn.close();

    }
    catch(SQLException Ex)
    {

    } 
}

这是错误 https://i.stack.imgur.com/aWO16.png

更新!! 我检查了我的项目,我得到了这个新错误 https://i.stack.imgur.com/uHRQW.png

我缺少什么?请帮助!!!!

我终于解决了!!

在 class Conexion y 中删除静态 final,我为此创建一个构造函数 class

public class Conexion {

public Conexion(){

}    
public Connection getConecction()
{
    Connection con = null;
    try{
        Class.forName("com.mysql.jdbc.Driver");
        con = DriverManager.getConnection("jdbc:mysql://localhost:3306/controldecalidad", "root", "");                        
    }catch(SQLException ex){            
    }
    catch(Exception ex){
    }
    return con;
    }    
}

然后我创建了一个 class 拥有所有操作

public class Operaciones 
{
   Conexion conexion;

public Operaciones()
{
    conexion = new Conexion();
}


public boolean registra_rechazo(String SKU,String fecha,String num_captura,int pesoCaptura)
{
    Boolean bandera=false;
     try
    {
        Connection conn = conexion.getConecction();
        java.util.Date utilStartDate = new java.util.Date(fecha);
        java.sql.Date sqlStartDate = new java.sql.Date(utilStartDate.getTime());           
        String sql = "INSERT INTO registra_rechazo VALUES(?,?,?,?)";
        PreparedStatement pst = conn.prepareStatement(sql);
        pst.setString(1, SKU);   
        pst.setDate(2, sqlStartDate);
        pst.setString(3, num_captura);
        pst.setInt(4, pesoCaptura);
        if(pst.executeUpdate()!=-1){
            bandera = true;
            return bandera;
        }
        else{
            bandera = false;
            return bandera;

        }

    }
    catch(SQLException Ex)
    {

    }
     return bandera;
   }
}

然后我调用web服务中的方法,但是首先必须像图片一样在web服务中通过add操作创建web方法

我不知道为什么,但该方法只有在您使用该向导创建方法时才有效

@WebMethod(operationName = "operation")
public boolean operation(@WebParam(name = "SKU") String SKU, @WebParam(name = "fecha") String fecha, @WebParam(name = "num_captura") String num_captura, @WebParam(name = "peso_captura") int peso_captura) {
    //TODO write your implementation code here:
     Operaciones op = new Operaciones();
    return op.registra_rechazo(SKU,fecha,num_captura,peso_captura);
}

然后 web 方法必须 return 东西,用 void 将不起作用
