idea spring+springmvc+mybatis环境配置整合详解

idea spring+springmvc+mybatis环境配置整合详解 === 1.配置整合前所需准备的环境: --- 1.1：jdk1.8 1.2：idea2017.1.5 1.3：Maven 3.5.2

2.查看idea中是否安装Maven插件:

 2.1：File --> Settings --> Plugins
2.2：如下图所示的步骤进行操作(注:安装完插件，idea会重新启动)
3.

3.idea创建Maven项目的步骤

4.搭建目录结构

下图就是我搭建Maven项目之后，添加对应的目录和文件

5.pom.xml文件配置

9.配置类:UserController

 @Controller
@RequestMapping("/user")
public class UserController {
 
  @Resource
  private UserService userService;
 
  @RequestMapping("/test")
  public String test() {
    return "list";
  }
 
  @RequestMapping("/index")

    User loginUser = userService.login(user);
    if (loginUser != null) {
      request.getSession().setAttribute("userName",loginUser.getUsername());
      return "success";
    }
    request.getSession().setAttribute("message","用户名或密码有误！！！");
    System.out.println(loginUser.getUsername());
    return "login";
  }
}

10.配置类:IUserDao

 public interface IUserDao {
 
    User login(User user);
 
    User selectByPrimaryKey(Integer id);
 
    int deleteByPrimaryKey(Integer id);
 
    int insert(User record);
 
    int insertSelective(User record);
 
    int updateByPrimaryKeySelective(User record);
 
    int updateByPrimaryKey(User record);
}

11.实体类:User.java

 public class User {
    
    private Integer id;
    private String email;
    private String password;
    private String phone;
    private String sex;
    private String sfz;
    private String truename;
    private String username;
 
    public Integer getId() {

    }
 
    public void setId(Integer id) {
        this.id = id;
    }
 
    public String getEmail() {

    }
 
    public void setSfz(String sfz) {
        this.sfz = sfz == null ? null : sfz.trim();
    }
 
    public String getTruename() {
        return truename;
    }
 
    public void setTruename(String truename) {
        this.truename = truename == null ? null : truename.trim();

    public String getUsername() {
        return username;
    }
 
    public void setUsername(String username) {
        this.username = username == null ? null : username.trim();
    }
}

12.UserService

 public interface UserService {
 
  User login(User user);
 
  User getUserById(String id);
 
  void add(User user);
 
  void update(User user);
}

13.IUserService

 @Service("userService")
public class IUserService implements UserService {
 
  @Autowired
  private IUserDao userDao;
 
 
  public User login(User user) {
    return userDao.login(user);
  }
 
  public User getUserById(String id) {
    return userDao.selectByPrimaryKey(Integer.parseInt(id));
  }
 
  public void add(User user) {
 
  }
 
  public void update(User user) {
 
  }
}

15.建立一个测试类，用于测试mybatis,类名：TestMybatis.java

 @RunWith(SpringJUnit4ClassRunner.class)     //表示继承了SpringJUnit4ClassRunner类
@ContextConfiguration(locations = {"classpath*:spring-mvc.xml","classpath*:spring-mybatis.xml"})
public class TestMybatis {
 
  private static Logger logger = Logger.getLogger(TestMybatis.class);
 
  @Autowired
  private IUserDao dao;
 
  @Test
  public void testSelectUser() throws Exception {
    Integer id = 1;
    User user = dao.selectByPrimaryKey(id);
    System.out.println(user.getUsername());
  }
}

如下图所示，则说明我们mybatis的配置是正确的！！！

16.配置项目的运行环境

17.接着新建一个jsp页面(index.jsp)，来测试springmvc+mybatis+spring的整合

 <%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>登陆界面</title>
    <script type="text/javascript">
       // window.location.href = "http://localhost:8080/MavenDemo/user/index";
       // window.location.href = "${pageContext.request.contextPath}/user/index";
    </script>
</head>
<body>
<h1>hello world!!!</h1>
<form action="${pageContext.request.contextPath}/user/login">
    用户名:<input type="text" name="username"><br>
    密&nbsp;&nbsp;&nbsp;&nbsp;码:<input type="password" name="password"><br>
    <input type="submit" value="submit"/>
</form>
</body>
</html>

18.成功之后的跳转界面(loginSuccess.jsp)

 <%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>信息界面</title>
</head>
<body>
<div style="padding-left: 10px;">
    <div class="panel panel-default">
        <div class="panel-heading" style="font-size: 18px;">用户信息</div>
        <table class="table" style="text-align: center;">
            <thead>
            <tr style="text-align: center;">
                <th style="width: 45px;">编号</th>
                <th style="width: 75px;">用户名</th>
                <th style="width: 75px;">密码</th>
                <th style="width: 145px;">真实姓名</th>
                <th style="width: 45px;">性别</th>
                <th style="width: 145px;">邮件</th>
                <th style="width: 145px;">联系电话</th>
            </tr>
            </thead>
            <tbody>
            <tr>
                <td>${currentUser.id }</td>
                <td>${currentUser.username}</td>
                <td>${currentUser.password }</td>
                <td>${currentUser.truename }</td>
                <td>${currentUser.sex }</td>
                <td>${currentUser.email }</td>
                <td>${currentUser.phone }</td>
            </tr>
            </tbody>
        </table>
    </div>
</div>
</body>
</html>

注：SpringMvc+Spring+Mybatis Maven的整合到此，已经整合完成了，再次过程中主要参考的https://www.cnblogs.com/hackyo/p/6646051.html 此篇博文的文章，在整合的过程当中也踩到一些坑，最终还是趟过了，在此就不列举出来，提醒下关于Mybatis的.xml数据库操作的配置文件，在此篇博文中需要存放在resources目录底下(不然项目测试的时候报错，也是搜索网上的博文得知，具体博文地址不记得了)
