该项目用来介绍SpringMVC对参数接受的方法:
项目目录树:在前一个项目上修改添加
新添加了Student类和Group类,用来测试整体参数接受
Student.java
package com.orange.model; public class Student { private String name; private String password; private Group group; public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public Group getGroup() { return group; } public void setGroup(Group group) { this.group = group; } }
Group.java
package com.orange.model; public class Group { private int id; private String name; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } }
提供控制类ParameterController.java
package com.orange.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.servlet.ModelAndView; import com.orange.model.Student; @Controller @RequestMapping(value="/parameter") public class ParameterController { @RequestMapping(value="/tp1") //参数逐个接受 public ModelAndView doParameter1(String name, String password, ModelAndView mav){ mav.addObject("name", name); mav.addObject("password", password); mav.setViewName("/parameterShow.jsp"); return mav; } @RequestMapping(value="/tp2") //参数整体接受,使用Student类中的属性来接受参数 public ModelAndView doParameter2(Student studenttp2, ModelAndView mav){ mav.addObject("studenttp2", studenttp2); mav.setViewName("/parameterShow.jsp"); return mav; } @RequestMapping(value="/tp3") //参数域属性接受 public ModelAndView doParameter3(Student studenttp3, ModelAndView mav){ mav.addObject("studenttp3", studenttp3); mav.setViewName("/parameterShow.jsp"); return mav; } @RequestMapping(value="/tp4") //参数修正,把提交的参数pname修改为name,参数ppassword修改为password public ModelAndView doParameter4(@RequestParam("pname") String name, @RequestParam("ppassword") String passwordtp4, ModelAndView mav){ mav.addObject("nametp4", name); mav.addObject("passwordtp4", passwordtp4); mav.setViewName("/parameterShow.jsp"); return mav; } }
