這裏需要一個Model文件，代碼是這樣的
package com.qcby.entity;
public class TestModel {
private String name;
private String passWord;
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;
}
}
Controller代碼
package com.qcby.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import com.qcby.entity.Article;
import com.qcby.entity.TestModel;

@Controller
@RequestMapping("/test")
public class TestController {//requestPerm方式
@RequestMapping("index")
public String index(HttpServletRequest request,HttpServletResponse response) {
String name=request.getParameter("name");
String passWord=request.getParameter("passWord");
System.out.println(name);
System.out.println(passWord);
return "index";
}
@RequestMapping("index2")//springMvc方式傳參
public String index2(@RequestParam("name") String name,@RequestParam("passWord") String passWord,HttpServletRequest request) {
request.setAttribute("name",name);
request.setAttribute("passWord",passWord);
return "index";
}
@RequestMapping("index3")
public String index3(String name,String passWord,HttpServletRequest request) {
request.setAttribute("name",name);
request.setAttribute("passWord",passWord);
return "index";
}
@RequestMapping("index4")
public String index4(String name,String passWord,Model model) {
model.addAttribute("name1",name);
model.addAttribute("passWord1",passWord);
return "index";
}
@RequestMapping("index5")
public String index5(Model model,TestModel testmodel)
{
model.addAttribute("name",testmodel.getName());
model.addAttribute("passWord",testmodel.getPassWord());
System.out.print(testmodel.getName());
System.out.print(testmodel.getPassWord());
return "index";
}
@RequestMapping("index6")
@ResponseBody
public Article index6( Article article) {
return article;
}
}
小結：不同的傳參方式有不同的使用優勢，酌情使用就好。
