SpringMVC学习过程中的代码及配置文件

1、传统Servlet回顾.

HelloServlet.

public class HelloServlet extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        String method = req.getParameter("method");
        PrintWriter out = resp.getWriter();
        System.out.println("dkdkddk");
        if (method != null && "hello".equals(method)){
//            out.write("hello,servlet");
            req.getRequestDispatcher("/WEB-INF/hello.jsp").forward(req, resp);
        }
    }

    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        doGet(req, resp);
    }
}

Web.xml.

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">

    <servlet>
        <servlet-name>hello</servlet-name>
        <servlet-class>controller.HelloServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>hello</servlet-name>
        <url-pattern>/hello</url-pattern>
    </servlet-mapping>
</web-app>

index.jsp.

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <head>
    <title>$Title$</title>
  </head>
  <body>
    <form action="/hello" method="post">
      <input type="hidden" name="method" value="hello"/>
      <input type="submit" value="提交"/>
    </form>
  </body>
</html>

hello.jsp.

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
    <h1>hello</h1>
</body>
</html>

2、SpringMVC入门案例.

HelloController.

//注意：这里我们先导入Controller接口
public class HelloController implements Controller {
    public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
        //ModelAndView 模型和视图
        ModelAndView mv = new ModelAndView();
        //封装对象，放在ModelAndView中。
        mv.addObject("msg","HelloSpringMVC!");
        //封装要跳转的视图，放在ModelAndView中
        mv.setViewName("hello");//: /WEB-INF/jsp/hello.jsp
        return mv;
    }
}

springmvc-servlet.xml.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd">
<!--    处理映射器-->
    <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping" />
<!--    处理器适配器-->

<!--    视图解析器-->
    <!--视图解析器:DispatcherServlet给他的ModelAndView-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="InternalResourceViewResolver">
        <!--前缀-->
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <!--后缀-->
        <property name="suffix" value=".jsp"/>
    </bean>


    <!--Handler 处理-->
    <bean id="/hello" class="controller.HelloController"/>
</beans>

        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

hello.jsp.

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
    <h1>hello,springMVC</h1>
</body>
</html>

3、SpringMVC注解开发.

HelloController.

@Controller
public class HelloController {

    @RequestMapping("/h")
    public String hello(Model model){
        model.addAttribute("msg","注解使用");
        return "hello";
    }
}

springmvc-servlet.xml.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop https://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <context:component-scan base-package="controller"/>
    <!-- 不处理静态资源 -->
    <mvc:default-servlet-handler/>
    <!-- 注解驱动 -->
    <mvc:annotation-driven/>
    <!-- 视图解析器 后面使用模板代替 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="internalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>


</beans>

Web.xml.

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">
    <!-- 配置dispatcherServlet -->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>

    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

Hello.jsp.

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
    ${msg}
</body>
</html>

4、SpringMVC RestFul风格.

RestfulController.

@Controller
public class RestfulController {

    //get请求方式获取的数据
    //@PathVariable : 把方法形参绑定到url模板变量上，（名要和{}里的相同），产生了restful的风格的url
    @RequestMapping(value="/restful/{param}",method = RequestMethod.GET)
    public String restful(@PathVariable int param, Model model){
        String content = "get请求传来的内容是" + param;
        model.addAttribute("msg",content);
        return "test";
    }

    //post请求方式获取数据
    @PostMapping(value = "/restful/{param}")
    public String restful(@PathVariable String param, Model model){
        String content = "post请求传来的内容是" + param;
        model.addAttribute("msg",content);
        return "test";
    }
}

springmvc-servlet.xml.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop https://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!--
    前面 springMVC 2 3
    是 springmvc实现的两种方式
    这里讲一下RestFul风格
    以往我们 发起请求主要是 表单(/addUser.action)和地址栏(?xxx=xx)
    通过不同的参数来实现不同的效果（不同的请求方式，使用的url不同，主要通过属性method达到不同的效果）

    Restful就是一个资源定位及资源操作的风格。不是标准也不是协议，只是一种风格。基于这个风格
设计的软件可以更简洁，更有层次，更易于实现缓存等机制。
    Restful风格请求的url： /item/1/2/
    好处：1.更加简洁
         2.更加安全
         3.根据不同的请求方式来实现不同的效果（请求地址（url）可以一样，但是不同的请求方式实现的功能可以不同）

    <!-- 扫描controller包，下面的注解类都要有spring容器管理 -->
    <context:component-scan base-package="controller"/>
    <!-- 不处理静态资源 -->
    <mvc:default-servlet-handler/>
    <!-- 注解驱动 -->
    <mvc:annotation-driven/>

    <!-- 视图解析器 后面使用模板代替 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="internalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

Web.xml.

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"

         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">

    <!-- dispatcherServlet注册 -->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!-- 通过初始化参数指定springMVC配置文件的位置，进行关联 -->

        <!-- 启动顺序，数字越小，启动越早 -->
        <load-on-startup>1</load-on-startup>

    <!-- 所有servlet请求都会被springmvc拦截 -->
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

index.jsp.

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <head>
    <title>$Title$</title>
  </head>
  <body>
  <h3>仔细看跳转的url</h3>
  <form action="/restful/1111" method="post">
    <input type="hidden" name="method" value="hello"/>
    <input type="submit" value="post提交"/>
  </form>
  <a href="/restful/1111">get方式提交：1111</a>
  </body>
</html>

test.jsp.

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
    ${msg}
</body>
</html>

5、SpringMVC结果跳转方式.

ModelAndView.

@Controller
public class TestController {

    //还有 继承Controller的那个方法我就不写了 直接上注解
    @RequestMapping("/t1")
//    @ResponseBody // 不同返回值不通过 视图解析器解析 ，直接返回
    public ModelAndView test(ModelAndView mv){
        mv.addObject("msg","采用ModelAndView设置的结果跳转");
        mv.setViewName("test");
        return mv;
    }
}

ServletApi.

@Controller
public class TestController2 {

    //还有 继承Controller的那个方法我就不写了 直接上注解
    @RequestMapping("/t2")
    @ResponseBody // 不同返回值不通过 视图解析器解析 ，直接返回
    public String test(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        //重定向我们就不说了 req.getSession()
        //转发
        req.setAttribute("msg","采用Servlet-api设置的结果跳转");
        req.getRequestDispatcher("/WEB-INF/jsp/test.jsp").forward(req, resp);
        return "";
    }
}

SpringMVC（Model）.

@Controller
public class TestController3 {

    //还有 继承Controller的那个方法我就不写了 直接上注解
    @RequestMapping("/t3")
//    @ResponseBody // 不同返回值不通过 视图解析器解析 ，直接返回
    public String  test(Model model){
        model.addAttribute("msg","采用springMVC设置的结果跳转");

        //1. 有视图解析器 ： 转发
        return "test";

        //2. 有视图解析器 ： 重定向
//        return "redirect:/index.jsp";
//        return "redirect:addUser.do";

        //3. 无视图解析器 ： 转发
//        return "/WEB-INF/jsp/test.jsp";
//        return "forward:/WEB-INF/jsp/test.jsp";

        //4. 无视图解析器 ： 重定向
//        return "redirect:/index.jsp";
    }
}

6、SpringMVC乱码问题解决.

Web.xml中设置，主要是请求参数的乱码处理

Controller.

@Controller
public class test {

    @GetMapping("/test")
    public String test1(@RequestParam("msg") String msg, Model model){
        model.addAttribute("msg",msg);
        return "index";
    }
    @PostMapping("/test")
    public String test2(@RequestParam("msg") String msg, Model model){
        model.addAttribute("msg",msg);
        return "index";
    }
}

    <!--spring 的编码过滤器 对get不太好
    (Tomcat8 以后tomcat的默认编码已经不是ISO-8859-1,而是改成了UTF-8，

    当然可以自己编写过滤器 -->
    <filter>
        <filter-name>encoding</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

        <filter-name>encoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

index.jsp.

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <head>
    <title>$Title$</title>
  </head>
  <body>
  <p>${msg}</p>
    <form method="post" action="/test">
      <input type="hidden" name="msg" value="你好"/>
      <input type="submit"/>
    </form>
    <a href="/test?msg='不好'">get</a>
  </body>
</html>

7、SpringMVC json使用及乱码解决.

Controller.

@ResponseBody
@Controller
public class UserController {


    //jackson 乱码问题解决 注解
    //属性 produces 指定响应体的放回类型和字符集
    @RequestMapping(value = "/jk1",produces = "application/json;charset=utf-8")
    public String jk1() throws JsonProcessingException {
        //创建一个Jackson对象映射器，用来解析数据

    pageSize 是固定的

    setCurrentPage ==> setOffset( offset = (current - 1) * pageSize )

    list 主要来源是 查询数据库获取的记录
    currentPage 是由前端传入，currentPage的初始值设为 1，offset初始值刚好为 0; 不设置就是默认首页
    count 是 查询出来的总记录数

    顺序有严格的规定(setPageSize) ==> setCount ==> setCurrentPage ==> 使用Page的getStart，getPageSize 完成 sql分页
