我正在学习 Spring MVC,我正在研究一个基本的表单示例,但我不知道为什么 bean 没有正确注入信息,所以我想知道是否有人可以指导我。
控制器
package com.carloscortina.Test;
import org.apache.log4j.Logger;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import com.carloscortina.toy.model.Member;
@Controller
public final class NomineeController {
private static final Logger log=
Logger.getLogger(NomineeController.class);
private String thanksViewName ="thanks";
public void setThanksViewName(String thanksViewName) {
this.thanksViewName = thanksViewName;
}
@RequestMapping(method = RequestMethod.GET)
public Member form() { return new Member();}
@RequestMapping(method = RequestMethod.POST)
public String processFormData(Member member){
log.info("Processing nominee: " + member);
log.info("thanksViewName: " + thanksViewName);
return thanksViewName;
}

我使用 STS 作为 IDE 并包含 Spring mvc 模板。我不确定bean没有被注入控制器,所以当它提交的表单正确重定向时,如果我在控制器中硬编码感谢它可以工作。
提前感谢您的帮助,我知道这可能是一个基本错误,所以谢谢。
*编辑 好吧,也许它与驱动的注释有关,但我仍然不确定,我无法让这个东西工作。所以控制器不能从 root-context.xml 中获取一个 bean?或者任何人都可以告诉我如何使用自动连线来做到这一点,这个想法只是不要在控制器上硬编码thanksViewName 的值。
