Question

我尝试使用spring和hibernate实现一对多关联。但是我不能使用单个表单实现两个模型属性。如何在单个表单中映射两个模型属性。

我的控制器代码是，

    @RequestMapping(value = "/admin/test", method = RequestMethod.GET)
    public ModelAndView adminTestPage(@ModelAttribute("employee") Employee employee, @ModelAttribute("education")Education education, BindingResult result, ModelMap map, Model model) {



        return new ModelAndView("test","command",new Employee());
}

我的jsp表单是，

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form"%>  
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>  
<%@taglib  uri="http://www.springframework.org/tags" prefix="spring" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<form:form method="post" action="saveEmp">  
        <table >  
          <tr>
          <td>Employee Name : </td> 
          <td><form:input path="empName"  /></td>
         </tr>  
         <tr>  
          <td>Address :</td>  
          <td><form:input path="empAddress" /></td>
         </tr> 
         <tr>  
          <td>Salary :</td>  
          <td><form:input path="salary" /></td>
         </tr>      
         <tr>  
          <td>Salary :</td>  
          <td><form:input path="qualification" /></td>
         </tr>   
         <tr>  
          <td>Salary :</td>  
          <td><form:input path="stream" /></td>
         </tr>  

         <tr>  
          <td>Age :</td>  
          <td><form:input path="empAge" />
          <input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}"/></td>
         </tr>                       
         <tr>  
          <td> </td>  
          <td><input type="submit" value="Save" /></td>  
         </tr>  
        </table>  
       </form:form>  
</body>
</html>

我的employee.java实体代码是，

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

    private static final long serialVersionUID = -723583058586873479L;

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column
    private Integer empId;

    @Column
    private String empName;


    @Column
    private String empAddress;

    @Column
    private Long salary;

    @Column
    private Integer empAge;

    @Transient
    private List<Education> education;
    public Integer getEmpId() {
        return empId;
    }

    public void setEmpId(Integer empId) {
        this.empId = empId;
    }

    public String getEmpName() {
        return empName;
    }

    public void setEmpName(String empName) {
        this.empName = empName;
    }

    public String getEmpAddress() {
        return empAddress;
    }

    public void setEmpAddress(String empAddress) {
        this.empAddress = empAddress;
    }

    public Long getSalary() {
        return salary;
    }

    public void setSalary(Long salary) {
        this.salary = salary;
    }

    public Integer getEmpAge() {
        return empAge;
    }

    public void setEmpAge(Integer empAge) {
        this.empAge = empAge;
    }

    public List<Education> getEducation() {
        return education;
    }

    public void setEducation(List<Education> education) {
        this.education = education;
    }







}

Education.java实体是，

@Entity
@Table(name="Education")
public class Education{

    @Id
    @SequenceGenerator(name = "seq_contacts", sequenceName = "seq_contacts")
    @GeneratedValue(strategy = GenerationType.AUTO, generator = "seq_contacts")
    private int eduID;

    @Column
    private String qualification;

    @Column
    private String stream;

    @ManyToOne
    @JoinColumn(name="empId")
    private Employee employee;
public Education(){

    }

    public Education(int eduID, String qualification,String stream, Employee employee )
    {
        super();
        this.eduID = eduID;
        this.qualification = qualification;
        this.stream=stream;
        this.employee = employee;
    }

    public int getEduID() {
        return eduID;
    }

    public void setEduID(int eduID) {
        this.eduID = eduID;
    }

    public String getQualification() {
        return qualification;
    }

    public void setQualification(String qualification) {
        this.qualification = qualification;
    }

    public String getStream() {
        return stream;
    }

    public void setStream(String stream) {
        this.stream = stream;
    }

    public Employee getEmployee() {
        return employee;
    }

    public void setEmployee(Employee employee) {
        this.employee = employee;
    }

错误是，
