（1），请求路径映射，请求方式GET或POST，浏览器地址传参
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServlet Request ;
/**
* @date: 2022/10/30 07:12
* @desc: 测试控制类
*/@Controller
@RequestMapping(value = "/studentConter")
public class StudentController {
// 路径映射
@RequestMapping(value = "/studentQuery", method = RequestMethod.GET) // 或RequestMethod.POST方式
public ModelAndView studentQuery(HttpServletRequest request) {
System.out.println("浏览器客户端请求到服务器的request.getParameter参数="+ request.getParameter("stuName"));
// 跳转页面
ModelAndView modelAndView = new ModelAndView();
modelAndView.setViewName("/testExamp/studentList jsp ");
return modelAndView;
}
} （1.1），浏览器地址访问及传参
张三 （2），请求方式POST表单方式传参，并自动装入实体对象
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletRequest;
/**
* @date: 2022/10/30 07:12
* @desc: 测试控制类
*/@Controller
@RequestMapping(value = "/studentConter")
public class StudentController {
@RequestMapping(value = "/studentQueryForm", method = RequestMethod.POST, produces = "text/html; charset =UTF-8")
public ModelAndView studentQueryForm(HttpServletRequest request, @ModelAttribute StudentVo studentVo) {
System.out.println("打印页面表单提交的数据，如姓名："+ studentVo.getsName());
System.out.println("打印页面表单提交的数据，如年龄："+ studentVo.getsAge());
// 跳转页面
ModelAndView modelAndView = new ModelAndView();
modelAndView.setViewName("/testExamp/studentListJsp");
return modelAndView;
}
} （2.1），实体类
/**
* @date: 2022/10/30 19:52
* @desc: 学生实体类
*/public class StudentVo implements Serializable {
private String sName = "";
private Integer sAge = 0;
private StudentFshu studentFshu = null;
// 注意自己去生成属性。。。
} （2.2），表单提交数据，自动装入实体对象
<%@ taglib prefix="form" uri="#34; %>
<%@ page language="java" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String contextPath = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title></title>
</head>
<body>
请求并响应到的第一个jsp页面。
<form action="<%=contextPath%>/studentConter/studentQueryForm" id="formID" method="post">
姓名：<input type="text" value="" name="sName" />
年龄：<input type="text" value="" name="sAge" />
<br/>
<input type="button" value="提交保存" onclick="on_submit()" />
</form>
</body>
<script type="text/javascript">
function on_submit() {
var formID = document.getElementById("formID");
formID.submit();
}
</script>
</html> （3），表单提交数据，提交复杂实体对象（即实体对象包含另一个实体对象）
import javax.servlet.http.HttpServletRequest;
/**
* @date: 2022/10/30 07:12
* @desc: 测试控制类
*/@Controller
@RequestMapping(value = "/studentConter")
public class StudentController {
// 路径映射
@RequestMapping(value = "/studentQueryFormFshu", method = RequestMethod.POST, produces = "text/html;charset=UTF-8")
public ModelAndView studentQueryFormFshu(HttpServletRequest request, @ModelAttribute StudentVo studentVo) {
System.out.println("打印页面表单提交的数据，如姓名："+ studentVo.getsName());
System.out.println("打印页面表单提交的数据，如附属姓名："+ studentVo.getStudentFshu().getFshuName() );
// 跳转页面
ModelAndView modelAndView = new ModelAndView();
modelAndView.setViewName("/testExamp/studentListJsp");
return modelAndView;
}
} （3.1），附属实体对象（被包含的实体对象，主实体是2.1实体对象）
import java .io.Serializable;
/**
* @date: 2022/10/30 20:53
* @desc: 学生实体类的附属
*/public class StudentFshu implements Serializable {
private String fshuName;
public String getFshuName() {
return fshuName;
}
public void setFshuName(String fshuName) {
this.fshuName = fshuName;
}
} （3.2），表单提交数据，提交复杂实体对象的jsp页面代码
<%@ taglib prefix="form" uri="#34; %>
<%@ page language="java" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String contextPath = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title></title>
</head>
<body>
<form action="<%=contextPath%>/studentConter/studentQueryFormFshu" id="formIDfshu" method="post">
姓名：<input type="text" value="" name="sName" />
附属姓名：<input type="text" value="" name="studentFshu.fshuName" />
<br/>
<input type="button" value="实体属性含自定义类，提交保存" onclick="on_submit_fshu()" />
</form>
</body>
<script type="text/javascript">
function on_submit_fshu() {
var formIDfshu = document.getElementById("formIDfshu");
formIDfshu.submit();
}
</script>
</html>
