Question

我在尝试搜索数据库中的某些数据时遇到了一些麻烦。我有输入标签，我写了一些文本，然后它从JSP获取到控制器，服务，并在dao我有一个查询，其中把这个字符串放入查询，当这个字符串是英文 - 一切正常，但当我写乌克兰搜索中的字符串不起作用。有人可以帮忙吗？

控制器方法

@RequestMapping(value = "/resultOfSearching", method =  
RequestMethod.GET)
public String getSearchResult(Model model,     
@ModelAttribute("searchChar")String searchResult)  {
    List<DeputesAppeal> deputesAppeals =  
deputesAppealService.abstractSearch(searchResult);
    model.addAttribute("ListOfAppeals", deputesAppeals);
    return "searchingResultPage";
}

服务方法

public List<DeputesAppeal> abstractSearch(String searchingChar) {
    return deputesAppealDao.abstractSearch(searchingChar);
}

和DaoLayer

public List<DeputesAppeal> abstractSearch(String searchingChar) {
    Query query = sessionFactory.getCurrentSession().createQuery("from   
DeputesAppeal where concat(NumberOfAppeal, DateOfIncomingAppeal,  
NameOfDepute, ResolutionOfChief, TypeOfAppeal)  like '%" + 
searchingChar + "%'");
    return query.list();
}

当sql登录

时

  from DEPUTES_APPEAL deputesapp0_ where concat(NumberOfAppeal,    
    DateOfIncomingAppeal, deputesapp0_.NameOfDepute,  
    deputesapp0_.ResolutionOfChief, TypeOfAppeal) like '%[B@7c815681%'

我认为您可以像这样使用字符编码过滤器（在您的web.xml文件中）：

<filter>
    <filter-name>CharacterEncodingFilter</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>

并将此过滤器放在web.xml中的第一个过滤器
