Java EE + Spring + Hibernate can't save UTF-8 characters into MySQL Database -

this question might marked duplicate, however, none of stackoverflow answers didn't me. i'm making website using java ee, spring , hibernate, other technologies, however, these relevant ones. website web store, , admin should able add product, it's name, price, manufacturer, etc... working, on website working except saving utf-8 characters in database. problem not in database, it's set utf-8, , if go phpmyadmin, can change characters in desired format, , display properly.

here's relevant product adding code...

admin product

@controller @requestmapping("/admin") public class adminproduct {      private path path;      @autowired     productservice productservice;        @requestmapping("/product/addproduct")     public string addproduct(model model) {          product product = new product();         product.setproductcategory("toys");         product.setproductstatus("available");          model.addattribute("product", product);          return "addproduct";       }        @requestmapping(value = "/product/addproduct", method = requestmethod.post)     public string addproductpost(@valid @modelattribute("product") product product, bindingresult result, httpservletrequest request) throws unsupportedencodingexception {         request.setcharacterencoding("utf-8");         if(result.haserrors()) {             return "addproduct";         }          productservice.addproduct(product);          multipartfile productimage = product.getproductimage();         string rootdirectory = request.getsession().getservletcontext().getrealpath("/");          path = paths.get(rootdirectory + "\\web-inf\\resources\\images\\" + product.getproductid() + ".png");          if(productimage != null && !productimage.isempty()) {             try {                 productimage.transferto(new file(path.tostring()));             } catch(exception e) {                 throw new runtimeexception("product image saving failed!");             }         }          return "redirect:/admin/productinventory";     } 

productdao implementation

 @repository     @transactional     public class productdaoimpl implements productdao {          @autowired         private sessionfactory sessionfactory;      public product getproductbyid(int id) {         session session = sessionfactory.getcurrentsession();         product product = (product) session.get(product.class, id);         session.flush();          return product;     }      public list<product> getproductlist() {         session session = sessionfactory.getcurrentsession();         query query = session.createquery("from product");         list<product> productlist = query.list();         session.flush();         return productlist;     }          public void  addproduct(product product) {             session session = sessionfactory.getcurrentsession();            session.saveorupdate(product);             session.flush();          }          public void  editproduct(product product) {             session session = sessionfactory.getcurrentsession();             session.saveorupdate(product);             session.flush();          }          public void  deleteproduct(product product) {             session session = sessionfactory.getcurrentsession();             session.delete(product);             session.flush();      } 

product model

try these steps

1. put utf-8 encoding filter in web.xml (the filter must first filter)

    <filter>      <filter-name>encoding-filter</filter-name>      <filter-class>          org.springframework.web.filter.characterencodingfilter      </filter-class>      <init-param>         <param-name>encoding</param-name>         <param-value>utf-8</param-value>      </init-param>      <init-param>         <param-name>forceencoding</param-name>         <param-value>true</param-value>      </init-param>   </filter>   <filter-mapping>       <filter-name>encoding-filter</filter-name>       <url-pattern>/*</url-pattern>  </filter-mapping> 

2. if use maven, add below pom.xml

     <properties>      <project.build.sourceencoding>utf-8</project.build.sourceencoding>       ...    </properties> 

3. if use tomcat, add uriencoding="utf-8" server.xml this

   <connector port="8080" protocol="http/1.1" connectiontimeout="20000"  redirectport="8443"  uriencoding="utf-8" />
