Spring mvc 简单练习

1. web.xml

 1  <!-- 解决post乱码问题 -->
 2   <filter>
 3     <filter-name>encoding</filter-name>
 4     <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
 5     <!-- 设置编码参是UTF8 -->
 6     <init-param>
 7       <param-name>encoding</param-name>
 8       <param-value>UTF-8</param-value>
 9     </init-param>
10   </filter>
11   <filter-mapping>
12     <filter-name>encoding</filter-name>
13     <url-pattern>/*</url-pattern>
14   </filter-mapping>
15   
16 <servlet>
17     <servlet-name>dispathcherServlet</servlet-name>
18     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
19     <init-param>
20       <param-name>contextConfigLocation</param-name>
21       <param-value>classpath:springmvc.xml</param-value>
22     </init-param>
23   </servlet>
24 
25   <servlet-mapping>
26     <servlet-name>dispathcherServlet</servlet-name>
27     <url-pattern>*.action</url-pattern>
28   </servlet-mapping>


29 </web-app>

2. springmvc.xml

1  
// web-->input.String --> bean.Date
<mvc:annotation-driven conversion-service="conversionService"></mvc:annotation-driven>
2 
3     <bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
4         <property name="converters">
5             <set>
6                 <bean class="com.xing.convert.DataConvert"></bean>
7             </set>
8         </property>
9     </bean>

3. package.convert --> Class DateConvert

package com.xing.convert;
import org.springframework.core.convert.converter.Converter;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class DataConvert implements Converter<String, Date> {
    @Override
    public Date convert(String s) {
        SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
        try {
            return format.parse(s);
        } catch (ParseException e) {
            e.printStackTrace();
        }
        return null;
    }
}

4. package.bean --> Account

 private Date birthday;

5. package.Control

 1  @Autowired
 2     @Qualifier("accountService")
 3     private AccountService accountService;
 4 
 5     @RequestMapping("all.action")
 6     public ModelAndView all(){
 7         List<Account> all = accountService.findAll();
 8         ModelAndView modelAndView = new ModelAndView();
 9         modelAndView.addObject("accounts",all);
10         modelAndView.setViewName("all.jsp");
11         return modelAndView;
12     }
13 
14     @ResponseBody
15     @RequestMapping("findById.action")
16     public String findById(Integer id){
17         return accountService.findById(id).toString();
18     }
19 
20     @ResponseBody
21     @RequestMapping("add.action")
22     public String add(Account account){
23         Integer add = accountService.add(account);
24         return add>0?"OK":"Sorry,Fail of Insert";
25     }
26 
27     @ResponseBody
28     @RequestMapping("showTime.action") // 这里是String --> Date 自动封装
29     public String showTime(Account account){
30         return account.toString();
31     }

6. index.jsp

 1 <%@page pageEncoding="UTF-8" %>
 2 <html>
 3 <body>
 4 
 5 <form action="showTime.action" method="get">
 6     <input type="text" name="name" placeholder="input your name...">
 7     <input type="text" name="birthday" placeholder="input your birthday...such as : 2000-01-01">
 8     <input type="submit" value="insert">
 9 </form>
10 </body>
11 </html>
