Question

例如，我需要从表单中保存几名员工：

<h4>Employee 1</h4>
<div>
<input type="text" name="names">
<input type="text" name="ages">
<input type="text" name="salaries">
</div>

<h4>Employee 2</h4>
<div>
<input type="text" name="names">
<input type="text" name="ages">
<input type="text" name="salaries">
</div>

<h4>Employee 3</h4>
<div>
<input type="text" name="names">
<input type="text" name="ages">
<input type="text" name="salaries">
</div>

为此我这样做：

public EmployeeAction extends ActionSupport {

  private String[] employeesNames;
  private Integer[] employeesAges;
  private Integer[] employeesSalaries;

  // Setters and getters

  public String save() {
    Employee[] employees = new Employee[size];
    // Creating employee objects with names, ages and salaries
    // and then save
    saveBatch(employees);
    return SUCCESS;
  }

}

有没有办法可以在不处理数组的情况下从表单保存数据，但仅仅为了节省一大堆员工？例如：

<h4>Employee 1</h4>
<div>
<input type="text" name="employees.name">
<input type="text" name="employees.age">
<input type="text" name="employees.salary">
</div>

<h4>Employee 2</h4>
<div>
<input type="text" name="employees.name">
<input type="text" name="employees.age">
<input type="text" name="employees.salary">
</div>

<h4>Employee 3</h4>
<div>
<input type="text" name="employees.name">
<input type="text" name="employees.age">
<input type="text" name="employees.salary">
</div>

和行动类：

public EmployeeAction extends ActionSupport {

  private Employee[] employees;

  // Setters and getters

  public String save() {
    saveBatch(employees);
    return SUCCESS;
  }

}

在Struts2中将实体数组作为参数发送
