org.springframework.web.util.NestedServletException:请求处理失败 [英] org.springframework.web.util.NestedServletException: Request processing failed

问题描述

我正在使用spring jdbc模板进行CRUD. 插入，选择和删除操作运行正常，但是在更新过程中出现了以下异常情况.

I am doing CRUD using spring jdbc template. insert,select and delete operations are working fine but I got these following exception in update process.

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [java.lang.Integer]: No default constructor found; nested exception is java.lang.NoSuchMethodException: java.lang.Integer.<init>()

这是我的控制器:

@RequestMapping(value="/editCompany/{companyId}", method= RequestMethod.GET)
    public String edit(@PathVariable(value="companyId")Integer companyId,ModelMap map) {

        Company company=companyService.get(companyId);
        map.addAttribute("company", company);
        map.put("companyId", companyId);
        return "editCompany"; 
    }

    @RequestMapping(value="/editCompany/{companyId}", method= RequestMethod.POST)
        public String save(@ModelAttribute("company")Integer companyId,Company company,BindingResult result, ModelMap map) {

        companyValidator.validate(company, result);
        if (result.hasErrors()) {
            return "editCompany";
        } else {
            Integer i=companyService.save(company);

            return "status";
        }
    }

我也为控制器使用了@Autowired注释. 怎么解决呢?任何帮助都将受到赞赏.

I have used @Autowired annotation for the controller too. How to resolve it? any kind of help is appreciated.

推荐答案

我将Post方法更改为following，并且有效.

I changed my Post method to following and it worked.

public String save(@ModelAttribute("company")Company company,BindingResult result, ModelMap map)
