Question

我是初学者，遇到了一个我无法理解的异常。从我的角度来看，一切似乎都很好，但是当我在我的 MVC WebApp 中执行搜索时，我总是得到同样的空响应。

看看我的代码。任何帮助将不胜感激。

我的控制器

@Controller
public class ControllerACP {

@RequestMapping("/search")
    public String Homea(Model model, @RequestParam(name = "query") String search) {
        
        model.addAttribute("clients", clientRepository.search(search));
        System.out.println(clientRepository.search(search)); // TO DISPLAY CONTENT ON CONSOLE
        System.out.println(search); // ALSO DISPLAY CONTENT ON CONSOLE
        return "search";
            
    }
}

我的仓库

public interface ClientRepository extends CrudRepository<Client, Integer> {

    @Query(value =  "select * from client where name LIKE ('%:?%')", nativeQuery = true)
    Iterable <Client> search(String search);
}

我的 HTML 文件

Answer 1

你可以试试这个查询：

<input class="inputX" id="idA"></input><br />
<input class="inputX" id="idB"></input><br />
<input class="inputX" id="idC"></input><br />
<input class="inputX" id="idD"></input><br />

Answer 2

我建议您调试代码并在 SSMS 中单独运行查询。然后更改您的查询并最终确定您获得所需输出的查询。

您的查询应该包含 %% 之间的搜索文本。类似的东西

@Query(value =  "select * from client where name LIKE ('%"+ searchedText +"%')", nativeQuery = true)

希望能帮到你。
