十四、增加EmployeeService实现用户添加
1.添加EmployeeAction，用来处理mainFrame界面中，用户提出的增删查改请求
1.1com.myz.web.actions包下新建EmployeeAction
package com.myz.web.actions; import java.util.Date; import javax.annotation.Resource; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.apache.struts.action.ActionForm; import org.apache.struts.action.ActionForward; import org.apache.struts.action.ActionMapping; import org.apache.struts.actions.DispatchAction; import com.myz.domain.Employee; import com.myz.service.interfaces.DepartmentServiceInterface; import com.myz.service.interfaces.EmployeeServiceInterface; import com.myz.web.forms.EmployeeForm; public class EmployeeAction extends DispatchAction {//跳往添加雇员界面 public ActionForward goAddEmp(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { // TODO Auto-generated method stub return mapping.findForward("goAddEmp"); } }
1.2struts-config.xml中配置EmployeeAction
<action path="/employee" parameter="flag" name="employeeForm"> <!-- 跳往雇员添加界面 --> <forward name="goAddEmp" path="/WEB-INF/addEmpUI.jsp"></forward> </action>
1.3applicationContext.xml中配置EmployeeAction
<!-- 配置EmployeeAction --> <bean name="/employee" class="com.myz.web.actions.EmployeeAction" scope="prototype"></bean>
1.4WEB-INF目录下新建addEmpUI.jsp
<body> <h1>添加雇员</h1> <form action="${pageContext.request.contextPath}/employee.do?flag=addEmp"" method="post"> <table> <tr><td>id:</td><td><input type="text" name="id"></td></tr> <tr><td>名字:</td><td><input type="text" name="name"></td></tr> <tr><td>邮件:</td><td><input type="text" name="email"></td></tr> <tr><td>密码:</td><td><input type="password" name="password"></td></tr> <tr><td>grade:</td><td><input type="text" name="grade"></td></tr> <tr><td>工资:</td><td><input type="text" name="salary"></td></tr> <tr><td>部门:</td><td> <select name="departmentid"> <option value="1">财务部</option> <option value="2">人事部</option> </select> </td></tr> <tr><td><input type="submit" value="登录"></td><td><input type="reset" value="重置"></td></tr> </table> </form> </body>
1.5完善EmployeeForm，以便addEmpUI.jsp的提交信息能够填充进去
package com.myz.web.forms; import org.apache.struts.action.ActionForm; public class EmployeeForm extends ActionForm { //属性名称与addEmpUI.jsp中的控件名称一样 private Integer id; private String password; private String email; private Integer grade; private String name; private float salary; private Integer departmentid; public String getEmail() { return email; } public Integer getDepartmentid() { return departmentid; } public void setDepartmentid(Integer departmentid) { this.departmentid = departmentid; } public void setEmail(String email) { this.email = email; } public Integer getGrade() { return grade; } public void setGrade(Integer grade) { this.grade = grade; } public String getName() { return name; } public void setName(String name) { this.name = name; } public float getSalary() { return salary; } public void setSalary(float salary) { this.salary = salary; } public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } }
1.6在struts-config.xml中将Employeeform与EmployeeAction相关联，并增加addEmp函数的forward
<action path="/employee" parameter="flag" name="employeeForm"> <forward name="goAddEmp" path="/WEB-INF/addEmpUI.jsp"></forward> </action>
1.7EmployeeAction中新建addEmp函数
package com.myz.web.actions; import java.util.Date; import javax.annotation.Resource; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.apache.struts.action.ActionForm; import org.apache.struts.action.ActionForward; import org.apache.struts.action.ActionMapping; import org.apache.struts.actions.DispatchAction; import com.myz.domain.Employee; import com.myz.service.interfaces.DepartmentServiceInterface; import com.myz.service.interfaces.EmployeeServiceInterface; import com.myz.web.forms.EmployeeForm; public class EmployeeAction extends DispatchAction { @Resource private DepartmentServiceInterface departmentService; @Resource private EmployeeServiceInterface employeeService; public EmployeeServiceInterface getEmployeeService() { return employeeService; } public void setEmployeeService(EmployeeServiceInterface employeeService) { this.employeeService = employeeService; } public DepartmentServiceInterface getDepartmentService() { return departmentService; } public void setDepartmentService(DepartmentServiceInterface departmentService) { this.departmentService = departmentService; } //跳往添加雇员界面 public ActionForward goAddEmp(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { // TODO Auto-generated method stub return mapping.findForward("goAddEmp"); } //添加雇员 public ActionForward addEmp(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { // TODO Auto-generated method stub EmployeeForm employeeForm=(EmployeeForm) form; Employee e=new Employee(); e.setName(employeeForm.getName()); e.setEmail(employeeForm.getEmail()); e.setGrade(employeeForm.getGrade()); e.setId(employeeForm.getId()); e.setHiredate(new Date()); e.setPassword(employeeForm.getPassword()); e.setSalary(employeeForm.getSalary()); System.out.println(employeeForm.getDepartmentid()); System.out.println(departmentService.getDepartmentById(employeeForm.getDepartmentid())); e.setDepartment(departmentService.getDepartmentById(employeeForm.getDepartmentid())); try { employeeService.addEmployee(e); } catch (Exception e2) { // TODO: handle exception return mapping.findForward("err"); } return mapping.findForward("ok"); } }
1.8增加ok.jsp和err.jsp
<body> <h2>操作成功！</h2> <a href="#">继续添加</a><br/> <a href="#">返回主界面</a> </body>
<body> <h2>操作失败</h2> <a href="#">返回主界面</a> </body>
1.9配置全局跳转的forward
<global-forwards> <!-- 跳往雇员添加成功界面 --> <forward name="ok" path="/WEB-INF/ok.jsp"></forward> <!-- 跳往雇员添加失败界面 --> <forward name="err" path="/WEB-INF/err.jsp"></forward> </global-forwards>
2.测试
在登录成功后，添加一个员工，在id不重复，其它属性类型填写正确的情况下，将会添加成功！
