org.springframework.web.filter.delegatingfilterproxy.dofilter(delegatingfilterproxy.java:260) please understand why search bean "name" instead of "object".
here contoller:
@controller public class maincontroller { @autowired private applicationcontext context; @requestmapping(value="hello") public @responsebody list<candidate> resultlist(){ electionsdao dao = context.getbean("electiondatasource", jdbcelectionsdao.class); return dao.getallcandidates(); } @requestmapping(value="get") public string getjson(){ return "get"; } @requestmapping(value="register") public string register(){ return "register"; } @requestmapping(value="/") public string mainpage(model model){ model.addattribute("object", new votingobject()); return "index"; } @requestmapping(value="login") public string login(){ return "login"; } @requestmapping(value="/success") public string successredirect(model model){ model.addattribute("object", new votingobject()); return "index"; } @requestmapping(value="/process", method=requestmethod.post) public string method(model model, @modelattribute("object") votingobject object, bindingresult result){ system.out.println(object.getname()); electionsdao dao = context.getbean("electiondatasource", jdbcelectionsdao.class); dao.insertthevote(object.getname()); return "redirect:/elections/"; } } here dao bean:
public class jdbcelectionsdao implements electionsdao { @autowired private datasource datasource; public list<candidate> getallcandidates() { list<candidate> candidatelist = new arraylist<candidate>(); connection conn = null; string sql = "select * candidates"; try { conn = datasource.getconnection(); statement statement = conn.createstatement(); resultset rs = statement.executequery(sql); while(rs.next()){ candidate candidate = new candidate(); candidate.setname(rs.getstring(2)); candidate.setvoices(rs.getint(3)); candidatelist.add(candidate); } } catch (sqlexception e) { // todo auto-generated catch block e.printstacktrace(); } return candidatelist; } public void insertthevote(string name) { // todo auto-generated method stub string sql = "update candidates set voices = voices+1 name= ?"; connection conn = null; try { conn=datasource.getconnection(); preparedstatement stmt = conn.preparestatement(sql); stmt.setstring(1, name); stmt.execute(); stmt.close(); } catch (sqlexception e) { // todo auto-generated catch block e.printstacktrace(); } finally{ try { conn.close(); } catch (sqlexception e) { // todo auto-generated catch block e.printstacktrace(); } } } public int registeruser(elector user) { // todo auto-generated method stub string sql = "insert users values(?,?,?)"; connection conn = null; try { conn=datasource.getconnection(); preparedstatement stmt = conn.preparestatement(sql); stmt.setstring(1, user.getname()); stmt.setstring(2, user.getlogin()); stmt.setstring(3, user.getpassword()); stmt.setboolean(4, user.isvoted()); stmt.close(); return stmt.getupdatecount(); } catch (sqlexception e) { // todo auto-generated catch block e.printstacktrace(); }finally{ try { conn.close(); } catch (sqlexception e) { // todo auto-generated catch block e.printstacktrace(); } } return 0; } public datasource getdatasource() { return datasource; } public void setdatasource(datasource datasource) { this.datasource = datasource; } } context.xml
<bean id="datasource" class="org.springframework.jdbc.datasource.drivermanagerdatasource"> <property name="driverclassname" value="com.mysql.jdbc.driver" /> <property name="url" value="jdbc:mysql://localhost:3306/elections" /> <property name="username" value="root" /> <property name="password" value="komato3" /> </bean> <bean id ="electiondatasource" class="ua.macko.dao.impl.jdbcelectionsdao" > <property name="datasource" ref="datasource"/> </bean>
imagine there list of products want display, :
in below form, can see, checking listproducts, attribute have added in controller using modelattribute. show how in controller code. jsp page :
<h3>product list</h3> <c:if test="${!empty listproducts}"> <table class="tg"> <tr> <th width="80">product id</th> <th width="120">product name</th> <th width="120">product description</th> </tr> <c:foreach items="${listproducts}" var="product"> <tr> <td>${product.productid}</td> <td>${product.productname}</td> <td>${product.productdescription}</td> </tr> </table> </c:if> controller :
@requestmapping(value="/product/show",method= requestmethod.get) public string listproducts(model model){ user user = userservice.getcurrentlyauthenticateduser(); model.addattribute("product", new productbasic()); model.addattribute("listproducts",this.productbasicservice.listproduct(user)); } servlet-context.xml :
if incase using hibernate, use such beans tied session factory, or else skip sesionfactory part.
<beans:bean id="canvasdao" class="com.journaldev.spring.dao.canvasdaoimpl"> <beans:property name="sessionfactory" ref="hibernate4annotatedsessionfactory"/> </beans:bean> <beans:bean id="canvasservice" class="com.journaldev.spring.service.canvasserviceimpl"> <beans:property name="canvasdao" ref="canvasdao"/> </beans:bean> as can see, calling listproduct returns list, , displaying on form...my model contains productid, productname, productdescription. if mistake change productname productxyz, error seeing. also, can post bean code related service,dao model?
