java - Not able to map fields using Hibernate Mapping -

i want establish 1 many relation between table vendor detail , product detail. 1 vendor can have multiple products. when inserting data table inserting 4 fields not mapping vendorid productdetail table , query generated this.

   hibernate: insert productinfo (productcategory, productdetails, productprice, vendorid) values (?, ?, ?, ?) shuld map vendor id in table empty.  

vendordetail.java

 package com.cts.entity;  import javax.persistence.*;   @entity  @table(name = "vendorinfo")  public class vendordetails {     @id     @column     private long vendorid;      @onetomany     private productdetails productdetail;      @column     private string vendorname;      @column     private string password;      public string getvendorname() {         return vendorname;     }     public void setvendorname(string vendorname) {         vendorname = vendorname;     }      public long getvendorid() {         return vendorid;     }     public void setvendorid(long vendorid) {         vendorid = vendorid;     }     public string getpassword() {         return password;     }     public void setpassword(string password) {         password = password;     } } 

productdetails.java

 package com.cts.entity;  import javax.persistence.cascadetype; import javax.persistence.column; import javax.persistence.entity; import javax.persistence.generatedvalue; import javax.persistence.generationtype; import javax.persistence.id; import javax.persistence.joincolumn; import javax.persistence.manytoone; import javax.persistence.onetoone; import javax.persistence.table;  @entity@table(name = "productinfo")  public class productdetails {      @manytoone(cascade = cascadetype.all)@joincolumn(name = "vendorid")     private vendordetails vendordetails;       public productdetails() {      }     @id     @generatedvalue(strategy = generationtype.identity)     @column     private int productid;     @column     private string productcategory;     @column     private string productdetails;     @column     private string productprice;     public vendordetails getvendordetails() {         return vendordetails;     }     public void setvendordetails(vendordetails vendordetails) {         this.vendordetails = vendordetails;     }     public int getproductid() {         return productid;     }     public void setproductid(int productid) {         this.productid = productid;     }     public string getproductcategory() {         return productcategory;     }     public void setproductcategory(string productcategory) {         this.productcategory = productcategory;     }     public string getproductdetails() {         return productdetails;     }     public void setproductdetails(string productdetails) {         this.productdetails = productdetails;     }     public string getproductprice() {         return productprice;     }     public void setproductprice(string productprice) {         this.productprice = productprice;     }  } 

dao class productdetaildaoimpl.java

 package com.cts.dao;  import org.hibernate.sessionfactory; import org.springframework.beans.factory.annotation.autowired; import org.springframework.stereotype.repository; import org.springframework.transaction.annotation.transactional;  import com.cts.entity.productdetails; import com.cts.entity.to.productdetailsto;  @repository  public class productdetaildaoimpl implements productdetaildao {      @autowired     sessionfactory sessionfactory;      @transactional     public boolean saveproductinfo(productdetailsto productto) {          system.out.println("m in registration dao");          system.out.println(productto.getproductcategory());         system.out.println(productto.getproductdetails());         system.out.println(productto.getproductid());         system.out.println(productto.getproductprice());          //getting productto data entity class         productdetails prodet = productto.getentity();          system.out.println("value of product details is:" + prodet.getproductdetails());          sessionfactory.getcurrentsession().save(prodet);         return false;     }  } 

vendordetails has many productdetails need make 1 many annotation this:-

@onetomany(mappedby="vendordetails") //mappedby value    declared //in  productdetails class. private collection<productdetails> productdetail=new arraylist<productdetails>; 

and create setter , getter of this.

now in productdetails class need annotate many 1 this:- @manytoone(cascade = cascadetype.all) @joincolumn(name = "vendorid") private vendordetails vendordetails; 

then new column named 'vendorid' create in table 'productinfo' , since declare mappedby value="vendordetails" each vendor id insert.
