在JSP中访问实体属性

Question

我有2个对象员工和员工地址。

这是我的2个对象 -

员工

    @Entity
    @Table(name="Employee")
    //@NamedQuery(name="Employee.findAll", query="SELECT e FROM Employee e")
    public class Employee implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private int id;

    private Timestamp created;

    @Temporal(TemporalType.DATE)
    private Date dob;

    private String email;

    @Column(name="FATHER_NAME")
    private String fatherName;

    private String firstname;

    private String lastname;

    private String married;

    @Column(name="MOTHER_NAME")
    private String motherName;

    private String telephone;

    //bi-directional many-to-one association to EmployeeAddress
    @OneToMany(mappedBy="employee")
    private List<EmployeeAddress> employeeAddresses;

    public Employee() {
    }

    public int getId() {
        return this.id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public Timestamp getCreated() {
        return this.created;
    }

    public void setCreated(Timestamp created) {
        this.created = created;
    }

    public Date getDob() {
        return this.dob;
    }

    public void setDob(Date dob) {
        this.dob = dob;
    }

    public String getEmail() {
        return this.email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getFatherName() {
        return this.fatherName;
    }

    public void setFatherName(String fatherName) {
        this.fatherName = fatherName;
    }

    public String getFirstname() {
        return this.firstname;
    }

    public void setFirstname(String firstname) {
        this.firstname = firstname;
    }

    public String getLastname() {
        return this.lastname;
    }

    public void setLastname(String lastname) {
        this.lastname = lastname;
    }

    public String getMarried() {
        return this.married;
    }

    public void setMarried(String married) {
        this.married = married;
    }

    public String getMotherName() {
        return this.motherName;
    }

    public void setMotherName(String motherName) {
        this.motherName = motherName;
    }

    public String getTelephone() {
        return this.telephone;
    }

    public void setTelephone(String telephone) {
        this.telephone = telephone;
    }

    public List<EmployeeAddress> getEmployeeAddresses() {
        return this.employeeAddresses;
    }

    public void setEmployeeAddresses(List<EmployeeAddress> employeeAddresses) {
        this.employeeAddresses = employeeAddresses;
    }

    public EmployeeAddress addEmployeeAddress(EmployeeAddress employeeAddress) {
        getEmployeeAddresses().add(employeeAddress);
        employeeAddress.setEmployee(this);

        return employeeAddress;
    }

    public EmployeeAddress removeEmployeeAddress(EmployeeAddress employeeAddress) {
        getEmployeeAddresses().remove(employeeAddress);
        employeeAddress.setEmployee(null);

        return employeeAddress;
    }

EmployeeAddress

@Entity
@Table(name="employee_address")
@NamedQuery(name="EmployeeAddress.findAll", query="SELECT e FROM EmployeeAddress e")
public class EmployeeAddress implements Serializable {
    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private int id;

    private String apt_no;

    private String city;

    private String country;

    @Temporal(TemporalType.TIMESTAMP)
    @Column(name="create_dt")
    private Date createDt;

    @Temporal(TemporalType.TIMESTAMP)
    @Column(name="end_dt")
    private Date endDt;

    private String state;

    private String street_addr;

    private String zip_Code;

    //bi-directional many-to-one association to Employee
    @ManyToOne
    @JoinColumn(name="emp_id")
    private Employee employee;

    public EmployeeAddress() {
    }

    public int getId() {
        return this.id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getApt_no() {
        return this.apt_no;
    }

    public void setApt_no(String apt_no) {
        this.apt_no = apt_no;
    }

    public String getCity() {
        return this.city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    public String getCountry() {
        return this.country;
    }

    public void setCountry(String country) {
        this.country = country;
    }

    public Date getCreateDt() {
        return this.createDt;
    }

    public void setCreateDt(Date createDt) {
        this.createDt = createDt;
    }


    public Date getEndDt() {
        return this.endDt;
    }

    public void setEndDt(Date endDt) {
        this.endDt = endDt;
    }

    public String getState() {
        return this.state;
    }

    public void setState(String state) {
        this.state = state;
    }

    public String getStreet_addr() {
        return this.street_addr;
    }

    public void setStreet_addr(String street_addr) {
        this.street_addr = street_addr;
    }

    public String getZip_Code() {
        return this.zip_Code;
    }

    public void setZip_Code(String zip_Code) {
        this.zip_Code = zip_Code;
    }

    public Employee getEmployee() {
        return this.employee;
    }

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

现在，我如何将此作为对象传递给我的JSP来收集员工信息。

如何显示地址属性..

例如： - 我显示如下的名字，它工作正常，但我如何显示address.street，address.zip等？

<form:form method="post" action="addemployee" commandName="employee">
        <table class="TFtable">
        <tr>
            <td><form:label path="firstname"><spring:message code="label.firstname"/></form:label></td>
            <td><form:input path="firstname" /></td>
        </tr>
