如何作為春豆接受非英語字符

Question

在我的項目中，我從form獲取非英語字符。如果獲取表單參數為@RequestParam，則顯示非英語字符。如果我以bean形式獲取表單參數，則顯示一些不需要的字符。

<form action="selva" method="get">
<input type="text" name="s" value="அன்பு" />
<input type="submit" value="fgf"/>
</form>
It displays:அன்பு
<form:form method="post" enctype="multipart/form-data" accept-charset="UTF-8" action="multipleSave" modelAttribute="multipleSave">
    <input type="text" name="userName" value="அன்பு"/>
<input type="submit" value="submit"> 
</form:form>
It prints : திலà®à®µà®¤à®¿

如何解決此錯誤。

任何幫助將不勝感激！！！

您可能缺少org.springframework.web.filter.CharacterEncodingFilter 。 您可以通過web.xml添加它

<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>
</filter>

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

或通過Spring Java配置文件：

import org.springframework.web.filter.CharacterEncodingFilter;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

import javax.servlet.FilterRegistration;
import javax.servlet.ServletContext;

public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        super.onStartup(servletContext);
        ....
        CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
        characterEncodingFilter.setEncoding("UTF-8");
        characterEncodingFilter.setForceEncoding(true);
        FilterRegistration.Dynamic filter = servletContext.addFilter("characterEncodingFilter", characterEncodingFilter);
        filter.addMappingForUrlPatterns(null, false, "/*");
        .....
    }
}
