使用struts添加学生

模块分析

1.导入jar包，在WEB-INF下建struts-config.xml，在web.xml对ActionServlet完成注册

<servlet-name>addStudent</servlet-name>

<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>

</servlet>

<servlet-mapping>

<servlet-name>addStudent</servlet-name>

<url-pattern>*.do</url-pattern>

</servlet-mapping>

2.创建AddStudentForm,继承ActionForm ，注册修改配置文件struts-config.xml

<form-beans>
<form-bean name="addStudentForm" type="demo.AddStudentForm"></form-bean>
</form-beans>

3.创建AddStudentAction，继承Action,覆盖execute方法，注册修改配置文件struts-config.xml

</action>

4.创建jsp页面

package demo;import org.apache.struts.action.ActionForm;public class AddStudentForm extends ActionForm {private String sname;private String major;private float score;private java.sql.Date birth;public String getSname() {return sname;}public void setSname(String sname) {this.sname = sname;}public String getMajor() {return major;}public void setMajor(String major) {this.major = major;}public float getScore() {return score;}public void setScore(float score) {this.score = score;}public java.sql.Date getBirth() {return birth;}public void setBirth(java.sql.Date birth) {this.birth = birth;}}

package demo;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.apache.struts.action.Action;import org.apache.struts.action.ActionForm;import org.apache.struts.action.ActionForward;import org.apache.struts.action.ActionMapping;public class AddStudentAction extends Action {private StudentDao studentDao=new StudentDao();@Overridepublic ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response)throws Exception {// TODO Auto-generated method stubAddStudentForm addStudentForm=(AddStudentForm)form;boolean bool=studentDao.addStudent(addStudentForm);if(bool==true) return mapping.findForward("addStudentSuccess");else return mapping.findForward("addStudentFailure");}}
