我正在学习 Spring MVC,并且正在尝试验证表单。当用户搜索空白字符串时,它会显示错误。执行代码时出现以下错误
Errors/BindingResult 参数应该紧跟在控制器方法签名中的模型属性参数之后: public java.lang.String com.mycompany.controller.catalog.SearchController.search(javax.servlet.http.HttpServletRequest,javax.servlet .http.HttpServletResponse,java.lang.String,org.springframework.validation.BindingResult,org.springframework.ui.Model) 抛出 javax.servlet.ServletException,java.io.IOException,org.broadleafcommerce.common.exception.ServiceException
package com.mycompany.controller.catalog;
import org.broadleafcommerce.common.exception.ServiceException;
import org.broadleafcommerce.core.web.controller.catalog.Mysearchcontroller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.method.support.ModelAndViewContainer;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
@Controller
@RequestMapping("/search")
public class SearchController extends Mysearchcontroller {
@RequestMapping("")
public String search(HttpServletRequest request, HttpServletResponse response,
@RequestParam(value = "q") String q,BindingResult errors,Model model) throws ServletException, IOException, ServiceException {
return search3(model, request,response, q ,errors);
}
}
