回顧helloword基本配置

web.xml

<servlet><servlet-name>SpringMVC_crud</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>SpringMVC_crud</servlet-name><url-pattern>/</url-pattern></servlet-mapping><filter><filter-name>CharacterEncodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param> <init-param><param-name>forceEncoding</param-name><param-value>true</param-value></init-param></filter><filter-mapping><filter-name>CharacterEncodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><filter><filter-name>HiddenHttpMethodFilter</filter-name><filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class></filter><filter-mapping><filter-name>HiddenHttpMethodFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping>

xxxx-sevlet.xml

<context:component-scan base-package="com.jh"></context:component-scan><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/pages/"></property><property name="suffix" value=".jsp"></property> </bean> @Controller public class helloController {@RequestMapping("/hello")public String hello(){return "success";} }

員工列表展示

訪問index.jsp---->直接發(fā)送/emps---->控制器查詢所有員工---->放在請(qǐng)求域中---->轉(zhuǎn)發(fā)到list頁面展示

@Controller public class EmployeeController {@AutowiredEmployeeDao employeeDao;/** 查詢所有員工*/@RequestMapping("/emps")public String getEmps(Model model){Collection<Employee> all = employeeDao.getAll();model.addAttribute("emps", all);return "list";}

index.jsp

<jsp:forward page="/emps"></jsp:forward>

list.jsp

<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %><title>員工列表</title> </head> <body> <h1>員工列表頁面</h1> <table border="1" cellpadding="5px" cellspacing="0"><tr><td>ID</td><th>lastName</th><th>email</th><th>gender</th><th>departmentName</th><th>edit</th><th>delete</th></tr><c:forEach items="${emps }" var="emp"><tr><td>${emp.id }</td><td>${emp.lastName }</td><td>${emp.email }</td><td>${emp.gender==0?"女":"男" }</td><td>${emp.department.departmentName }</td><td>edit</td><td>delete</td></tr></c:forEach> </table> </body>

添加

1、list.jsp點(diǎn)擊“員工添加”---->2、查詢出所有的部門信息要展示在頁面---->3、來到add.jsp---->4、輸入員工數(shù)據(jù)---->5、點(diǎn)擊保存---->6、處理器收到員工保存請(qǐng)求（保存員工）---->7、保存完成后來到list.jsp

/** 去員工添加頁面，去之前查出所有部門信息進(jìn)行展示*/@RequestMapping("/toaddpage")public String toAddPage(Model model){//1.查出所有部門Collection<Department> departments = departmentDao.getDepartments();//2.放在請(qǐng)求域中model.addAttribute("depts", departments);model.addAttribute("employee", new Employee());//3.去添加頁面return "add";}

list.jsp

add.jsp

<%@taglib prefix="form" uri="http://www.springframework.org/tags/form" %><h1>員工添加</h1> <form:form action="" modelAttribute="employee">lastName:<form:input path="lastName"/><br>email:<form:input path="email"/><br>gender:<br>男：<form:radiobutton path="gender" value="1"/><br>女：<form:radiobutton path="gender" value="0"/><br>dept:<form:select path="department.id" items="${depts }" itemLabel="departmentName" itemValue="id"></form:select><br><input type="submit" value="保存"></form:form>

聯(lián)系

5、點(diǎn)擊保存

/** 保存員工*/ @RequestMapping(value="/emp",method=RequestMethod.POST)public String addEmp(Employee employee){System.out.println("要添加的員工；"+employee);employeeDao.save(employee);return "redirect:/emps";}

add.jsp

<%pageContext.setAttribute("ctp", request.getContextPath());%><form:form action="${ctp }/emp" modelAttribute="employee" method="POST">

聯(lián)系：

運(yùn)行結(jié)果

修改

/** 修改*/@RequestMapping(value="/emp/{id}",method=RequestMethod.PUT)public String updateEmp(@ModelAttribute("employee")Employee employee){System.out.println("要修改的員工"+employee);//更新保存二合一employeeDao.save(employee);return "redirect:/emps";}/** 提前查詢員工*/@ModelAttributepublic void myModelAttribute(@RequestParam(value="id",required=false)Integer id,Model model){if(id!=null){Employee employee = employeeDao.get(id);model.addAttribute("employee", employee);}}

list.jsp
為edit加鏈接

<%pageContext.setAttribute("ctp", request.getContextPath());%><td><a href="${ctp }/emp/${emp.id }">edit</a></td><td>delete</td></tr></c:forEach> </table> <a href="${ctp }/toaddpage">添加員工</a>

edit.jsp

<%pageContext.setAttribute("ctp", request.getContextPath());%> <h1>員工修改頁面</h1> <form:form action="${ctp }/emp/${employee.id }" modelAttribute="employee" method="post"><input type="hidden" name="_method" value="put"><input type="hidden" name="id" value="${employee.id }">email:<form:input path="email"/>gender:   男：<form:radiobutton path="gender" value="1"/>   女：<form:radiobutton path="gender" value="0"/><br>dept:<form:select path="department.id" items="${depts }"itemLabel="departmentName" itemValue="id"></form:select><br><input type="submit" value="修改"> </form:form>

刪除

/** 刪除*/ @RequestMapping(value="/emp/{id}",method=RequestMethod.DELETE) public String deleteEmp(@PathVariable("id")Integer id){employeeDao.delete(id);return "redirect:/emps"; }

list.jsp

總結(jié)
