struts2中的ModelDriven

<div class="unit">
	<label>学生姓名：</label>
	<input type="text" name="studentScores.stuName" value="${studentScores.stuName}" size="30" class="required" maxlength="20" />
</div>
			
<div class="unit">
	<label>考试名称：</label>
	<input type="text" name="studentScores.examName" value="${studentScores.examName}" size="30" maxlength="20" class="required" />
</div>
			
<div class="unit">
	<label>考试分数：</label>
	<input type="text" name="studentScores.score" value="${studentScores.score}" size="30" maxlength="20" class="required" />
</div>

其中studentScores.student.stuName是对应后台action的熟悉，action是这样写的

public class StudentExamAction extends ActionSupport {


	// 学生实体
	private Student studentScores;

	//查询学生的分数
	public String queryScores(){
	
		.....
		.....
	}
	

	public Student getStudentScores() {
		return studentScores;
	}

	public void setStudentScores(Student studentScores) {
		this.studentScores = studentScores;
	}

	
}

首先让action类继承ModelDriven接口，并实现getModel接口：

/**
 * 
 * 
 * @author : xqf
 * @group : tgb8
 * @Date : 2013-12-31 14:07:29
 * @Version : 1.0.0
 */
public class StudentExamAction extends ModelDriven {


	// 学生实体
	private Student studentScores;

	//实现getModel方法
	 @Override
    public Object getModel() {

       if(studentScores == null){
           studentScores = new studentScores();
       }
       return studentScores;

    }

	
	//查询学生的分数
	public String queryScores(){
	
		.....
		.....
	}
	

	public Student getStudentScores() {
		return studentScores;
	}

	public void setStudentScores(Student studentScores) {
		this.studentScores = studentScores;
	}

	
}

<div class="unit">
			
	<label>学生姓名：</label>
	<input type="text" name="stuName" value="${stuName}" size="30" class="required" maxlength="20" />
</div>

<div class="unit">
	<label>考试名称：</label>
	<input type="text" name="examName" value="${examName}" size="30" maxlength="20" class="required" />
</div>

<div class="unit">
	<label>考试分数：</label>
	<input type="text" name="score" value="${score}" size="30" maxlength="20" class="required" />
</div>
