08SpringMvc_(1)继承AbstractCommandController的Action[能够以实体的形式，收集客户端参数].(2)日期转换器和编码过滤器

上一篇文章说过要介绍两个控制器。这篇文章就介绍第二个控制器AbstractCommandController（这个类已经快要被废弃了，有更好的代替者，但还是要好好学这个类）。这个控制器的额作用是为了收集提交的参数，

比如说之前的写法是：//获取员工的姓名 String username=request.getParameter("username");这样去收集参数，提交的参数一多这样很不方便，所以引入了AbstractCommandController。记住SringMVC中的Action是单例模式，Strut2中的Action是多例模式，所以这就造成了他们收集参数的方式是绝对不同的。

案例如下：

先给出具体代码实现，在进行讲解。

第一步：先写index.jsp.

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">

    <title>My JSP 'index.jsp' starting page</title>
    <meta http-equiv="pragma" content="no-cache">
    <meta http-equiv="cache-control" content="no-cache">
    <meta http-equiv="expires" content="0">
    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
    <meta http-equiv="description" content="This is my page">
    <!--
    <link rel="stylesheet" type="text/css" href="styles.css">
    -->
  </head>
  <body>
  <form action="${pageContext.request.contextPath}/adduser.action" method="post">
   <table border="2" align="center">
   <tr>
     <th>姓名</th>
     <td> <input type="text" name="username"  /></td>
   </tr>

    <tr>
     <th>性别</th>
     <td> <input type="radio" name="gender" value="男" />男
          <input type="radio" name="gender"  value="女" checked/>女
     </td>
   </tr>
  <!--   <tr>
     <th>入职时间</th>
     <td> <input type="text" name="username"  /></td>
   </tr>
    -->
   <tr>
   <td>
     <input type="submit" value="提交">
   </td>

   </tr>
   </table>

  </form>

  </body>
</html>

第二步：写Emp.java，这个文件里面的属性就是要和前面的jsp页面提交的数据要完全吻合（名字必须要一模一样）。就是为了收集页面数据的。

package com.guigu.shen.Action4;

public class Emp {
    //名字（与表单中的name属性必须要一模一样）
private String username;
//性别
private String gender;
/**
 * @return the username
 */
/**
 *
 */
public Emp() {
    // TODO Auto-generated constructor stub
}
public String getUsername() {
    return username;
}
/**
 * @param username the username to set
 */
public void setUsername(String username) {
    this.username = username;
}
/**
 * @return the gender
 */
public String getGender() {
    return gender;
}
/**
 * @param gender the gender to set
 */
public void setGender(String gender) {
    this.gender = gender;
}
}

第三步：写EmpAction.java

package com.guigu.shen.Action4;

import javax.jws.WebParam.Mode;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.validation.BindException;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractCommandController;

public class EmpAction extends AbstractCommandController{
/**
 * 我们知道SpringMvc的Action是单例模式的，所以他收集从页面传过来的参数的方式与Struts2不一样
 * SpringMVC能够以实体的形式，收集客户端参数
 */
//mvc会走无参的构造器，可以通过里面的代码(this.setCommandClass(Emp.class);)，匹配jsp页面中的参数信息
public EmpAction() {
    //第一步：自动将表单参数封装到Emp对象中
this.setCommandClass(Emp.class);
System.out.print("EmpAcion的无参构造函数");
}

/*
 * 参数command表示可以分装好的实体类（Emp）
 *
 */
    @Override
    protected ModelAndView handle(HttpServletRequest request,
            HttpServletResponse response, Object command, BindException errors)
            throws Exception {

        ModelAndView modelAndView=new ModelAndView();

        //第二步：command就是Emp对象传进来的。
        System.out.println("handle方法");
        Emp emp=(Emp) command;
        modelAndView.addObject("message", "增加员工成功");
        System.out.println("员工的名字"+emp.getUsername());
        System.out.println("员工的性别"+emp.getGender());
         modelAndView.setViewName("/jsp/success.jsp");

        return modelAndView;
    }

}

第四步：springmvc_004.xml配置文件、

<?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/mvc/spring-mvc-3.0.xsd"
>
     <!-- 控制器(程序员)（必须配置） -->

<bean name="/adduser.action" class="com.guigu.shen.Action4.EmpAction"></bean>
<!-- 映射器 -->
<!-- 适配器
SimpleControllerHandlerAdapter不仅能去找实现了Controller接口的Action
还能去找继承了AbstractCommandController类的Action

 -->

</beans>

第五步：springmvc.xml文件

<?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
      http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

      http://www.springframework.org/schema/context
      http://www.springframework.org/schema/context/spring-context-3.0.xsd

      http://www.springframework.org/schema/mvc
      http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"
>
<import resource="com/guigu/shen/Action4/springmvc_004.xml"/>
</beans>

第六步：web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>SpringMvc_10day_self</display-name>
  <servlet>
  <!--这个名字可以随便取得，但是这个名字取了之后，以后在 WEB-INF下面创建SpirngMVC的配置文件是，命名必须以这个开头，

  所以这里取名叫做DispatcherServlet，那么之后的xml文件取名必须为DispatcherServlet-servlet.xml（一个字都不能差）

  -->
  <servlet-name>DispatcherServlet</servlet-name>
  <servlet-class> org.springframework.web.servlet.DispatcherServlet</servlet-class>
 <!-- 通知DispatcherServlet去指定目录下找到springmvc.xml配置文件 -->
 <!--
 注意这里的  <param-name>contextConfigLocation</param-name>一个字母都不能有错
 一旦有错就会去WEB-INF下面去找
  -->
          <init-param>
               <param-name>contextConfigLocation</param-name>
              <param-value>classpath:springmvc.xml</param-value>
          </init-param>
 </servlet>
 <servlet-mapping>
   <servlet-name>DispatcherServlet</servlet-name>
    <url-pattern>*.action</url-pattern>

 </servlet-mapping>

  <welcome-file-list>

    <welcome-file>index.jsp</welcome-file>

  </welcome-file-list>
</web-app>

运行：输入：http://127.0.0.1:8080/SpringMvc_10day_self/

结果是：正常运行。但是有一个问题。控制台从网页那边得到的中文乱码：

员工的名字?¨???±??±
员工的性别???

先不管这个，我们讲一下这个案例的执行流程：我们要现实的功能其实就是从index.xml页面上输入员工的姓名和性别。然后在EmpAtion中得到这些属性。这里用的是在EmpAction中定义Emp这么一个类，然后由这个类会自动去装配信息。

-------------------------------------------------------------------------------------------------------------------------------------------------------------

好，介绍好流程以后，我们再来解决一下上面的乱码问题。我们以前解决这种问题通常是在EmpAction.java中加一句request.setCharacterEncoding("utf-8");

我们先试试看这样可以吗?试了，答案是不可以。

输出：员工的名字爱爱
       员工的性别女

问题解决了。

---------------------------------------------------------------------------------------------------------------------------------------------------------------

这个问题解决了，我们在加一个功能，在员工的入职日期也加进去。在index.xml中修改代码。如下：

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">

    <title>My JSP 'index.jsp' starting page</title>
    <meta http-equiv="pragma" content="no-cache">
    <meta http-equiv="cache-control" content="no-cache">
    <meta http-equiv="expires" content="0">
    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
    <meta http-equiv="description" content="This is my page">
    <!--
    <link rel="stylesheet" type="text/css" href="styles.css">
    -->
  </head>
  <body>
  <form action="${pageContext.request.contextPath}/adduser.action" method="post">
   <table border="2" align="center">
   <tr>
     <th>姓名</th>
     <td> <input type="text" name="username"  /></td>
   </tr>

    <tr>
     <th>性别</th>
     <td> <input type="radio" name="gender" value="男" />男
          <input type="radio" name="gender"  value="女" checked/>女
     </td>
   </tr>
    <tr>
     <th>入职时间</th>
     <td> <input type="text" name="userdata" value="2015-3-2" /></td>
   </tr>

   <tr>
   <td>
     <input type="submit" value="提交">
   </td>

   </tr>
   </table>

  </form>

  </body>
</html>

然后在Emp.java中也修改代码，多一个Data userdata属性。

package com.guigu.shen.Action4;

import java.util.Date;

public class Emp {
    //名字
private String username;
/**
 * @return the userdata
 */
public Date getUserdata() {
    return userdata;
}
/**
 * @param userdata the userdata to set
 */
public void setUserdata(Date userdata) {
    this.userdata = userdata;
}
//性别
private String gender;
private Date userdata;
/**
 * @return the username
 */
/**
 *
 */
public Emp() {
    // TODO Auto-generated constructor stub
}
public String getUsername() {
    return username;
}
/**
 * @param username the username to set
 */
public void setUsername(String username) {
    this.username = username;
}
/**
 * @return the gender
 */
public String getGender() {
    return gender;
}
/**
 * @param gender the gender to set
 */
public void setGender(String gender) {
    this.gender = gender;
}
}

再在EmpAction.java中加一句   System.out.println("員工的入職日誌"+emp.getUserdata().toLocaleString());

package com.guigu.shen.Action4;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.validation.BindException;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractCommandController;

/*
 * Create by 沈晓权
 * Create on 2016年8月7日下午8:28:10
 */
public class EmpAction extends AbstractCommandController{
/**
 * 我们知道SpringMvc的Action是单例模式的，所以他收集从页面传过来的参数的方式与Struts2不一样
 * SpringMVC能够以实体的形式，收集客户端参数
 */
//mvc会走无参的构造器，可以通过里面的代码(this.setCommandClass(Emp.class);)，匹配jsp页面中的参数信息
public EmpAction() {
    //第一步：自动将表单参数封装到Emp对象中
this.setCommandClass(Emp.class);
System.out.print("EmpAcion的无参构造函数");
}

/*
 * 参数command表示可以分装好的实体类（Emp）
 *
 */
    @Override
    protected ModelAndView handle(HttpServletRequest request,
            HttpServletResponse response, Object command, BindException errors)
            throws Exception {

        ModelAndView modelAndView=new ModelAndView();

        //第二步：command就是Emp对象传进来的。
        System.out.println("handle方法");
        Emp emp=(Emp) command;
        modelAndView.addObject("message", "增加员工成功");
        System.out.println("员工的名字"+emp.getUsername());
        System.out.println("员工的性别"+emp.getGender());
        System.out.println("員工的入職日誌"+emp.getUserdata().toLocaleString());
         modelAndView.setViewName("/jsp/success.jsp");

        return modelAndView;
    }

}

运行之后：结果不行。直接出错。

 Request processing failed; nested exception is java.lang.NullPointerException
出错的原因是在收集从index.xml的数据时出错了，导致Emp没有被实例化，然后造成空指针了。

怎么解决呢？

当然，不一定要是yyy-MM-dd这种形式的，是可以改的。
我们修改下代码：

package com.guigu.shen.Action4;

import java.text.SimpleDateFormat;
import java.util.Date;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.xml.crypto.Data;

import org.springframework.beans.propertyeditors.CustomDateEditor;
import org.springframework.validation.BindException;
import org.springframework.web.bind.ServletRequestDataBinder;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractCommandController;

public class EmpAction extends AbstractCommandController{
/**
 * 我们知道SpringMvc的Action是单例模式的，所以他收集从页面传过来的参数的方式与Struts2不一样
 * SpringMVC能够以实体的形式，收集客户端参数
 */
//mvc会走无参的构造器，可以通过里面的代码(this.setCommandClass(Emp.class);)，匹配jsp页面中的参数信息
public EmpAction() {
    //第一步：自动将表单参数封装到Emp对象中
this.setCommandClass(Emp.class);
System.out.print("EmpAcion的无参构造函数");
}

/*
 * 参数command表示可以分装好的实体类（Emp）
 *
 */
    @Override
    protected ModelAndView handle(HttpServletRequest request,
            HttpServletResponse response, Object command, BindException errors)
            throws Exception {

        ModelAndView modelAndView=new ModelAndView();

        //第二步：command就是Emp对象传进来的。
        System.out.println("handle方法");
        Emp emp=(Emp) command;
        modelAndView.addObject("message", "增加员工成功");
        System.out.println("员工的名字"+emp.getUsername());
        System.out.println("员工的性别"+emp.getGender());
        System.out.println("員工的入職日誌"+emp.getUserdata().toLocaleString());
         modelAndView.setViewName("/jsp/success.jsp");

        return modelAndView;
    }

    @Override
    protected void initBinder(HttpServletRequest request,
            ServletRequestDataBinder binder) throws Exception {
     /* 
向springmvc内部注入一个自定义的类型转换器
参数一：将String转换成什么类型的字节码
参数二：自定义转换规则
     */
        binder.registerCustomEditor(Date.class,new CustomDateEditor(new SimpleDateFormat("yyyy-MM-dd"), true) );
    }

}

问题解决了。

---------------------------------------------------------------------------------------------------------------------------------------------------------------

最后我们再实现一个功能：把emp这个类封装到modelAndView。传递给success.jsp然后在success.jsp中把emp里面的数据显示出来。

EmpAction.java改为

/**

 */
package com.guigu.shen.Action4;

import org.springframework.web.bind.ServletRequestDataBinder;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractCommandController;

/*

public class EmpAction extends AbstractCommandController{
/**

 * SpringMVC能够以实体的形式，收集客户端参数
 */
//mvc会走无参的构造器，可以通过里面的代码(this.setCommandClass(Emp.class);)，匹配jsp页面中的参数信息
public EmpAction() {
    //第一步：自动将表单参数封装到Emp对象中
this.setCommandClass(Emp.class);
System.out.print("EmpAcion的无参构造函数");
}

/*

 */
    @Override
    protected ModelAndView handle(HttpServletRequest request,
            HttpServletResponse response, Object command, BindException errors)
            throws Exception {

        ModelAndView modelAndView=new ModelAndView();

        //第二步：command就是Emp对象传进来的。
        System.out.println("handle方法");
        Emp emp=(Emp) command;
        modelAndView.addObject("message", "增加员工成功");
        System.out.println("员工的名字"+emp.getUsername());
        System.out.println("员工的性别"+emp.getGender());
        System.out.println("員工的入職日誌"+emp.getUserdata().toLocaleString());
        modelAndView.addObject("emp", emp);
        modelAndView.setViewName("/jsp/success.jsp");

        return modelAndView;
    }

    /* (non-Javadoc)
     * @see org.springframework.web.servlet.mvc.BaseCommandController#initBinder(javax.servlet.http.HttpServletRequest, org.springframework.web.bind.ServletRequestDataBinder)
     */
    @Override
    protected void initBinder(HttpServletRequest request,
            ServletRequestDataBinder binder) throws Exception {

        binder.registerCustomEditor(Date.class,new CustomDateEditor(new SimpleDateFormat("yyyy-MM-dd"), true) );
    }

}

success.jsp改为：

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

    <base href="<%=basePath%>">

    ${message}
     姓名:${requestScope.emp.username }</br>
      入职时间:${requestScope.emp.userdata }</br>

</html>

运行结果为：增加员工成功 姓名:爱爱
             入职时间:Mon Mar 02 00:00:00 CST 2015

发现入职时间这个显示格式不好。我们修改一下success.jsp的代码

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>
<%
String path = request.getContextPath();

     <!-- 

     1)fmt:formatDate 来源于http://java.sun.com/jsp/jstl/fmt
     2)fmt:formatDate作用是格式化日期的显示。例如2015年5月10号 星期五
     3) value表示需要格式化的值
     4)typez表示现实的日期，时间都要显示
     type=data表示只显示  日期
     type=time 表示只显示时间
     type=both 时间个日期都要显示
     dateStyle="full"这个有好几种格式，看具体的要求
      -->
            入职时间:<fmt:formatDate
            value="${requestScope.emp.userdata}"
            type="date"
            dateStyle="full"
           />
  </body>
</html>

运行结果是:

增加员工成功 姓名:爱爱
入职时间:Mon Mar 02 00:00:00 CST 2015

入职时间:2015年3月2日 星期一

结束。
