Question

我在jsp中有一个带有发送按钮的表单：

 <form role="form" action="/admin/newUserTest/" method="post">
       <input type="text" class="form-control" id="firstname" name="firstname">
       <input type="text" class="form-control" id="lastname" name="lastname">
       <input type ="send" value="Send">
</form>

和控制器：

@RequestMapping(value="/newUserTest", method = RequestMethod.POST)
public ModelAndView newUserTest(@RequestParam("firstname")String firstname,@RequestParam("lastname")String lastname){
    ModelAndView model = new ModelAndView();
    System.out.println(firstname);
    System.out.println(lastname);
  ...

我在表（mysql）中写的名字和姓氏。当method =“get”时，它写入正确，但是当method =“post”时，它会写出错误的符号，如ÑÐ·ÐμÑ3。并且控制台写出符号?????μ?? 3。我该如何解决这个问题？

Answer 1

我解决了我的问题，添加到web.xml：

<filter>
    <filter-name>encoding-filter</filter-name>
    <filter-class>
        org.springframework.web.filter.CharacterEncodingFilter
    </filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
        <param-name>forceEncoding</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>

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

这是由于spring无法使用正确的编码。确保在web.xml中注册CharacterEncodingFilter

 <filter>  
<filter-name>encodingFilter</filter-name>  
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>  
<init-param>  
   <param-name>encoding</param-name>  
   <param-value>UTF-8</param-value>  
</init-param>  
<init-param>  
   <param-name>forceEncoding</param-name>  
   <param-value>true</param-value>  
</init-param>  
</filter>  
<filter-mapping>  
  <filter-name>encodingFilter</filter-name>  
  <url-pattern>/*</url-pattern>  
</filter-mapping>

如果您使用的是基于Java类的配置。使用

        messageSource.setDefaultEncoding("UTF-8");

希望有助于解决问题。
