如何搭建ssm+web项目

1，创建web项目

项目结构:

2,导入需要的jar包

3，spring-mvc.xml

4,创建数据库，表，实体类

CREATE TABLE `user` (
    `userId` INT(11) NOT NULL AUTO_INCREMENT,
    `type` INT(11) NOT NULL DEFAULT '1' COMMENT '类型：0 管理员 1 普通用户',
    `username` VARCHAR(50) NULL DEFAULT NULL,
    `password` VARCHAR(50) NULL DEFAULT NULL,
    `status` INT(11) NOT NULL DEFAULT '0' COMMENT '0：未激活 1：在使用',
    PRIMARY KEY (`userId`)
)

User.java

package com.tbk.entity;

import java.io.Serializable;


public class User implements Serializable{

  
    private static final long serialVersionUID = 1L;
    
    private Integer userId;
    private Integer type;
    private String username;
    private String password;
    private Integer status;
    public Integer getUserId() {
        return userId;
    }
    public void setUserId(Integer userId) {
        this.userId = userId;
    }
    public Integer getType() {
        return type;
    }
    public void setType(Integer type) {
        this.type = type;
    }
    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public Integer getStatus() {
        return status;
    }
    public void setStatus(Integer status) {
        this.status = status;
    }
    
    
}

 5, controller,service dao

UserContrller.java

package com.tbk.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

import com.tbk.entity.User;
import com.tbk.service.UserService;

@Controller
@RequestMapping("/user")
public class UserController {

    @Autowired
    private UserService userService;
    
    @RequestMapping(value="/list",method=RequestMethod.GET)
    public  ModelAndView     getList(){
        List<User> uList=userService.getAll();
        ModelAndView mView=new ModelAndView();        
        mView.addObject("users", uList);
        mView.setViewName("sys/user");
        return mView;
    }
}

UserService.java

package com.tbk.service;

import java.util.List;

import com.tbk.entity.User;

public interface UserService {

    List<User> getAll();

}

UserServiceImpl.java

package com.tbk.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.tbk.dao.UserDao;
import com.tbk.entity.User;
import com.tbk.service.UserService;

@Service
public class UserServiceImpl implements UserService {
    
    @Autowired
    private UserDao userDao;
    
    @Override
    public List<User> getAll() {
        
        return userDao.getAll();
    }

}

UserDao.java

package com.tbk.dao;

import java.util.List;

import com.tbk.entity.User;

public interface UserDao {

    List<User> getAll();

}

6,UserMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.tbk.dao.UserDao" >

        from user

7,user.jsp

                     </td>
                     </tr>
                 </c:forEach>

        </div>
        <div id=down></div>
    </div>

8,部署到tomcat,访问：localhost:8080/tbk/user/list
