mysql - Value '0000-00-00' can not be represented as java.sql.Date

I'm working on some project which needs to extract data from DB and I use Spring MVC to build model from DB for selecting data.

Here is the problem with my JSP page:

<form action="result" method="get" >
<table>
<thead>
<tr>
<th>Date to select:</th>
<th>Name to select:</th>
<th>Type to select:</th>
</tr>
</thead>

<tbody>
<tr>
<td><form:select  path="listOfDates">
<form:option value="NONE"> --SELECT--</form:option>
<form:options items="${listOfDates}"></form:options>
</form:select>
</td>  
<td><form:select  path="listOfInstitutionsNames">
<form:option value="NONE"> --SELECT--</form:option>
<form:options items="${listOfInstitutionsNames}"></form:options>
</form:select>
</td>
<td>
<form:select  path="listOfInstitutionsTypes">
<form:option value="NONE"> --SELECT--</form:option>
<form:options items="${listOfInstitutionsTypes}"></form:options>
</form:select>
</td>
</tr>
</tbody>

<tfoot>
<tr>
<td><input type="submit" value="Извлечь"/></td>
</tr>
</tfoot>

</table>
</form>

As you can see I try to use <form:select> from Spring tag library.
Question:
but when it's preparing my model with this controller:

@Controller
public class HomeController{ 

    @Autowired
    private ControllerSupportClass controllerSupportClass; 


        @RequestMapping(value="/search", method=RequestMethod.GET)
        public String search(Model model) {
            List<Date> listOfDates = controllerSupportClass.findAllDatesForm();
            List<String> listOfInstitutionsNames = controllerSupportClass.findAllInstitutionsForm();
            List<String> listOfInstitutionsTypes = controllerSupportClass.findAllTypesForm();
            model.addAttribute("listOfInstitutionsTypes", listOfInstitutionsTypes);
            model.addAttribute("listOfInstitutionsNames", listOfInstitutionsNames);
            model.addAttribute("listOfDates", listOfDates);
            return "search";    
        }


        @RequestMapping(value ="/result", method=RequestMethod.GET)
        public String SecondActionPage(@RequestParam String particularDate, 
                                       @RequestParam String nameOfInstitution, 
                                       @RequestParam String typeName,
                                       Model model) throws Exception {


                if(particularDate !="" && nameOfInstitution.trim() !="" && typeName.trim()=="") {                   
                    controllerSupportClass.findWithDateAndName(nameOfInstitution, particularDate, model);                   
                } else if(particularDate.trim() !="" && nameOfInstitution.trim() =="" && typeName.trim() !="") {                    
                    controllerSupportClass.findWithAddedDateAndType(typeName, particularDate, model);                   
                } else if(particularDate.trim() !="" && nameOfInstitution.trim() =="" && typeName.trim() ==""){         
                    controllerSupportClass.findWithAddedDate(particularDate, model);    
                } else if(particularDate.trim() !="" && nameOfInstitution.trim() !="" && typeName.trim() !="") {
                    throw new Exception("Search by choose all parameters is not exceptable");   
                } else {    
                    throw new Exception("You didn't put any search parameters");    
                }           
            return "search";
        }

}

It gives me an error like this:

WARN : org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/controller/] in DispatcherServlet with name 'appServlet' Hibernate: select distinct creationda0_.DATE_ID as DATE1_0_, creationda0_.CHILD_ADMISSION_DATE as CHILD2_0_, creationda0_.CHILD_GO_SCHOOL_DATE as CHILD3_0_, creationda0_.PARTICULAR_DATE as PARTICULAR4_0_, creationda0_.VERSION as VERSION0_ from CREATION_DATE creationda0_ WARN : org.hibernate.util.JDBCExceptionReporter - SQL Error: 0, SQLState: S1009 ERROR: org.hibernate.util.JDBCExceptionReporter - Value '0000-00-00' can not be represented as java.sql.Date Jun 19, 2013 3:26:53 PM org.apache.catalina.core.StandardWrapperValve invoke SEVERE: Servlet.service() for servlet [appServlet] in context with path [/controller] threw exception [Request processing failed; nested exception is org.hibernate.exception.GenericJDBCException: could not execute query] with root cause java.sql.SQLException: Value '0000-00-00' can not be represented as java.sql.Date

If you need my Entity class it's here I'm using Date from java.util, but I go with @Temporal annotation to convert it from SQL to unit Date as I understand:

@Entity
@Table(name="CREATION_DATE")
public class CreationDate implements Serializable {


    private int dateId;

        @Id
        @GeneratedValue(strategy=IDENTITY)
        @Column(name="DATE_ID")
        public int getDateId() {
            return dateId;
        }

        public void setDateId(int dateId) {
            this.dateId = dateId;
        }


    private int version;

        @Version
        @Column(name="VERSION")
        public int getVersion() {
            return version;
        }

        public void setVersion(int version) {
            this.version = version;
        }


    private Date particularDate;

        @Temporal(TemporalType.DATE)
        @DateTimeFormat(pattern="yyyy-MM-dd")
        @Column(name="PARTICULAR_DATE")
        public Date getParticularDate() {
            return particularDate;
        }

        public void setParticularDate(Date particularDate) {
            this.particularDate = particularDate;
        }


    private Date childGoSchoolDate;

        @Temporal(TemporalType.DATE)
        @DateTimeFormat(pattern="yyyy-MM-dd")
        @Column(name="CHILD_GO_SCHOOL_DATE")
        public Date getChildGoSchoolDate() {
            return childGoSchoolDate;
        }

        public void setChildGoSchoolDate(Date childGoSchoolDate) {
            this.childGoSchoolDate = childGoSchoolDate;
        }


    private Date childAdmissionDate;

        @Temporal(TemporalType.DATE)
        @DateTimeFormat(pattern="yyyy-MM-dd")
        @Column(name="CHILD_ADMISSION_DATE")
        public Date getChildAdmissionDate() {
            return childAdmissionDate;
        }

        public void setChildAdmissionDate(Date childAdmissionDate) {
            this.childAdmissionDate = childAdmissionDate;
        }


}

Assuming that the problem with data type conversion is because MVC uses String, but the actual type is Date.

In MySql '0000-00-00' is considered a valid date, but it can't be repesented as java.sql.Date.

You could use a query that returns NULL in case date is '0000-00-00', or the actual value otherwise:

SELECT
  CASE WHEN `date`!='0000-00-00' THEN `date` END new_date
FROM
  yourtable

or you can add to your datasource connection string this:

zeroDateTimeBehavior=convertToNull

and dates as '0000-00-00' will be automatically converted to NULL.
