先在一個包中建立一個類，然後再配置sprringmvacontroller.xml並連結到該類。

<context:component-scan base-package="cn.happy.controllerreturn"></context:component-scan>

package cn.happy.Controler;
import org.springframework.stereotype.Controller
 
;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

/**
 * Created by java on 2017/8/18.
 */
@Controller
@RequestMapping("/user")
public class 
 
HappyController {
    @RequestMapping("/first")
    public String doFirst(){
        return "/WEB-INF/index.jsp";
    }

    @RequestMapping("/second")
    public  String doSecond(){
        return "/WEB-INF/insert.jsp";
    }

    @RequestMapping("/*thtird")
    public String doThird(){
        return  "/WEB-INF/delete.jsp"
 
;
    }

    @RequestMapping("/**/fourth")
    public  String   doFourth(){
        return  "/WEB-INF/insert.jsp";
    }

    @RequestMapping("/*/six")
    public String doSix(){
        return "/WEB-INF/insert.jsp";
    }

//路徑變數
    @RequestMapping(value = "/{name}/{age}/first.do",method = {RequestMethod.POST,RequestMethod.GET})
    public String  doFirstcoller(@PathVariable() String name, @PathVariable() String age){
        System.out.println(name);
        System.out.println(age);
        return "/WEB-INF/index.jsp";
    }

    @RequestMapping(value = "/first.do",method = {RequestMethod.POST,RequestMethod.GET})
    public String  doFirst(String name, Model model){
        System.out.println("name"+name);
        model.addAttribute("name"+name);
        return "index";
    }
}

 請求中方式的定義：

   method屬性的取值為Requestmethod，是一個列舉常量

   先建立一個UserInfo 實體類並寫上屬性，並進行封裝：   

   域屬性：一個類中變數的型別是另外一個自定義型別。

public class UserInfo {
    private String name;
    private  Book book;
    private List<Book> books;
    public List<Book> getBooks() {
        return books;
    }

    public void setBooks(List<Book> books) {   //集合屬性
        this.books = books;
    }

    public Book getBook() {
        return book;
    }

    public void setBook(Book book) {
        this.book = book;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

並且再建立Book的實體類，也寫上一個屬性，將其進行封裝

public class Book {
    private String bookname;

    public String getBookname() {
        return bookname;
    }

    public void setBookname(String bookname) {
        this.bookname = bookname;
    }
}

之後建立ArgementController類

@Controller
public class ArgementController {
    @RequestMapping("/login2")     //限定請求方式
        public String login2(UserInfo  info){
        System.out.println(info.getName());
        return "/WEB-INF/delete.jsp";
        }

    @RequestMapping("/AreArggement")
    public String login4(UserInfo  info){
        System.out.println(info.getName()+"\t"+info.getBook().getBookname());
        return "/WEB-INF/delete.jsp";
    }

//@RequestParam  校正引數名稱

    @RequestMapping("/rightArggument")
    public String  logg3(@RequestParam("name") String uname2){
        System.out.println(uname2);
        return "/WEB-INF/delete.jsp";
    }

@RequestMapping("/listArgument")
public String listlogin5(UserInfo info){
    System.out.println(info.getName()+"\t"+info.getBooks().get(0).getBookname());
        return "/WEB-INF/delete.jsp";
}

}

Web.xml

亂碼解決forceEncoding

<!--javaWeb 三大件 servlet Filter listener -->
<filter>
    <filter-name>CharactorEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

       <param-value>utf-8</param-value>

    <init-param>
      <param-name>forceEncoding</param-name>

  </filter>
