@Autowired自动注入失败

新手注意的问题

package cn.ryq.web.controller;

import cn.ryq.domain.company.Company;import cn.ryq.service.company.CompanyService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;

import java.util.Date;import java.util.List;

@Controller@RequestMapping("/system/company")public class CompanyController {    @Autowired    public CompanyService companyService;

    @RequestMapping("/list.do")    public ModelAndView list(){        List<Company> list = companyService.findAll();        ModelAndView mv= new ModelAndView();        mv.addObject("list",list );        mv.setViewName("company/company-list");        return mv;    }}在确保ApplicationContext-service.xml,有扫包(可以通过右边的小叶子图标来查看是否有扫到包)CompanyController控制器中有@Controller,再检查web.xml的配置,一般情况下我们都是用多个模块去完成一个项目,那么web.xml下就如下配置,

<context-param>   <param-name>contextConfigLocation</param-name>   <param-value>classpath*:spring/applicationContext-*.xml</param-value></context-param>加载配置文件的路径加*,让web可以扫到整个项目的配置文件!
