开发步骤

第一步:配置springmvc.xml

<mvc:annotation-driven/>

<context:component-scan base-package="控制器的包路径"/>

第二步:写控制器

@Controller

@RequestMapping

package com.ssm.controller;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;

import com.ssm.pojo.User;
import com.ssm.service.user.UserService;

@Controller
@RequestMapping("/sys/user")
public class UserController {
    
    @Resource
    private UserService userService;
    
    @RequestMapping("/qry")
    public String findUserByNR(@RequestParam("name")String name,@RequestParam("roleId")String roleId,Model model){
        List<User> users=userService.findUserByNR(name, roleId);
        model.addAttribute("users", users);
        return "index";
    }

    public UserService getUserService() {
        return userService;
    }
    public void setUserService(UserService userService) {
        this.userService = userService;
    }
}

第三步:测试
