SpringMVC06_表单标签库
原生表单示例：
- tag.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ page isELIgnored="false" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<h1>学生信息</h1>
<form>
学生ID：<input type="text" name="id" value="${student.id}"/><br>
学生姓名：<input type="text" name="name" value="${student.name}"/><br>
学生年龄：<input type="text" name="age" value="${student.age}"/><br>
<input type="submit" value="提交"/>
</form>
</body>
</html>
- TagHandler
package com.blu.controller;
import com.blu.entity.Student;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
@RequestMapping("/tag")
public class TagHandler {
@GetMapping("/get")
public ModelAndView get(){
ModelAndView modelAndView = new ModelAndView("tag");
Student student = new Student(1L,"张三",22);
modelAndView.addObject("student",student);
return modelAndView;
}
}
表单标签库示例：
- tag.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ page isELIgnored="false" %>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<h1>学生信息</h1>
<form:form modelAttribute="student">
学生ID：<form:input path="id"/><br>
学生姓名：<form:input path="name"/><br>
学生年龄：<form:input path="age"/><br>
<input type="submit" value="提交"/>
</form:form>
</body>
</html>
注：使用表单标签库需要引入 http://www.springframework.org/tags/form 标签文件
modelAttribute绑定Model对象student，子表单中的path属性绑定Model对象的属性值
