- 1.創建項目
- 2. 使用maven導入需要的包
- 3.配置tomcat
- 4.完善項目結構
- 4.配置springMVC並測試
- 5.配置文件Mybaits
- 代碼編寫示例，登錄功能
- 效果
1.創建項目
new一個project
進行下一步
繼續下一步，設置項目名，存放位置，項目所屬公司
2. 使用maven導入需要的包
查看maven配置，及使用本地庫
導包
導入spring框架所需的包
首先在properties中加入spring.version
然后導入依賴

3.配置tomcat
添加tomcat
配置tomacat，主要是tomcat版本,端口，默認網址
4.完善項目結構
在java中添加controller,services,dao,entity,interceptor四個package。
在entity中存放實體類，在controller中處理頁面請求request與返回給頁面信息，dao層調用處理數據庫，services存放調用的各種方法,interceptor中保存過濾器相關的類。
完善webapp
在webapp下添加static文件夾，用來存放js等相關文件。
在webapp下進行index.jsp，作為初始界面。

當前文件結構
添加對應的javeBean
在springMVC-servlet中配置controller
在applicationContext-mybaits中添加services層和dao層
測試
啟動tomcat。結果在瀏覽器中顯示index.jsp界面
在login.jsp中添加登錄表格
<section class="loginCont" style="text-align: center">
<form class="loginForm" action="${pageContext.request.contextPath }/dologin" name="actionForm" id="actionForm" method="post" >
<div class="info">${error}</div>
<div class="inputbox">
<%--@declare id="user"--%><label for="user">用戶名：</label>
<input type="text" class="input-text" id="userCode" name="userCode" placeholder="請輸入用戶名" required/>
</div>
<div class="inputbox">
<%--@declare id="mima"--%><label for="mima">密碼：</label>
<input type="password" id="userPassword" name="userPassword" placeholder="請輸入密碼" required/>
</div>
<div class="subBtn">
<input type="submit" value="登錄"/>
<input type="reset" value="重置"/>
</div>
</form>
</section>
在controller層添加LoginController類
package com.test.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
/**
*
*/
@Controller
public class LoginController {
@RequestMapping("/test")
public String welcome() {
return "login";
}
}
在地址欄中輸入http://localhost:8080/test
此時SpringMVC結構
5.配置文件Mybaits
新建database.properties中放置數據庫連接內容
driver=com.mysql.jdbc.Driver
url=jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC
user=root
password=root
minIdle=45
maxIdle=50
initialSize=5
maxActive=100
maxWait=100
removeAbandonedTimeout=180
removeAbandoned=true
在applicationContext-mybaits.xml中配置數據庫連接,整合mybaits與springMVC,配置事務管理

代碼編寫示例，登錄功能
功能描述
在頁面login.jsp填寫用戶名和密碼信息，controller層根據路徑調用方法，在數據庫查詢用戶，如果存在的話將用戶信息存放在session中，否則返回錯誤信息。
Session可以作為獨立的信息單獨存放，可以建立Constants類來存放信息。

2.設計數據庫建立用戶信息表格
創建表
CREATE TABLE `test_user` (
`id` BIGINT(20) NOT NULL AUTO_INCREMENT COMMENT '主鍵ID',
`userCode` VARCHAR(15) COLLATE utf8_unicode_ci DEFAULT NULL COMMENT '用戶編碼',
`userName` VARCHAR(15) COLLATE utf8_unicode_ci DEFAULT NULL COMMENT '用戶名稱',
`userPassword` VARCHAR(15) COLLATE utf8_unicode_ci DEFAULT NULL COMMENT '用戶密碼',
`gender` INT(10) DEFAULT NULL COMMENT '性別（1:女、 2:男）',
`birthday` DATE DEFAULT NULL COMMENT '出生日期',
`phone` VARCHAR(15) COLLATE utf8_unicode_ci DEFAULT NULL COMMENT '手機',
`address` VARCHAR(30) COLLATE utf8_unicode_ci DEFAULT NULL COMMENT '地址',
PRIMARY KEY (`id`)
) ENGINE=INNODB AUTO_INCREMENT=16 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
insert into `test_user`
(`id`,`userCode`,`userName`,`userPassword`,`gender`,`birthday`,`phone`,`address`)
values
(1,'admin','系統管理員','1234567',1,'1983-10-10','13688889999','北京市海淀區成府路207號'),
(2,'liming','李明','0000000',2,'1983-12-10','13688884457','北京市東城區前門東大街9號'),
(5,'hanlubiao','韓路彪','0000000',2,'1984-06-05','18567542321','北京市朝陽區北辰中心12號'),
(6,'zhanghua','張華','0000000',1,'1983-06-15','13544561111','北京市海淀區學院路61號'),
(7,'wangyang','王洋','0000000',2,'1982-12-31','13444561124','北京市海淀區西二旗輝煌國際16層'),
(8,'zhaoyan','趙燕','0000000',1,'1986-03-07','18098764545','北京市海淀區回龍觀小區10號樓'),
(10,'sunlei','孫磊','0000000',2,'1981-01-04','13387676765','北京市朝陽區管庄新月小區12樓'),

3.根據表在entity中建立實體類User
根據數據庫中的表產生，使用Setter和Getter產生set和get方法
package com.test.entity;
import com.alibaba.fastjson.annotation.JSONField;
import org.hibernate.validator.constraints.Length;
import org.hibernate.validator.constraints.NotEmpty;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Past;
import java.util.Date;
public class User {
private Integer id; //id
@NotEmpty(message="用戶編碼不能為空")
private String userCode; //用戶編碼
@NotEmpty(message="用戶名稱不能為空")
private String userName; //用戶名稱
@NotNull(message="密碼不能為空")
@Length(min=6,max=10,message="用戶密碼長度為6-10")
private String userPassword; //用戶密碼
private Integer gender; //性別
@Past(message="必須是一個過去的時間")
//@DateTimeFormat(pattern="yyyy-MM-dd")
@JSONField(format="yyyy-MM-dd")
private Date birthday; //出生日期
private String phone; //電話
private String address; //地址
}
4 新建Constants類存放session信息
package com.test.tools;
public class Constants {
public static final String USER_SESSION = "userSession";
public final static String SYS_MESSAGE = "message";
}
5 編寫Controller層
需要注意，要把controller層在springMVC-servlet中注冊為javaBean
package com.test.controller;
import com.test.entity.User;
import com.test.service.user.UserService;
import com.test.tools.Constants;
import org.apache.log4j.Logger;
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.RequestParam;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
/**
*
*/
@Controller
public class LoginController {
//log4j
private static final Logger logger= Logger.getLogger(LoginController.class);
//service層
@Autowired
private UserService userService;
@RequestMapping("/test")
public String welcome() {
return "login";
}
//提交登陸表單，實現登陸功能
@RequestMapping(value = "/doLogin")
public String doLogin(@RequestParam(value = "userCode") String userCode,
@RequestParam(value = "userPassword") String password,
HttpSession session,
HttpServletRequest request){
logger.debug("enter LoginController =====>doLogin method");
//和數據庫中的用戶信息進行校驗
User loginUser = this.userService.login(userCode, password);
if(loginUser !=null){//說明用戶存在
//使用session容器，把該用戶放進去
session.setAttribute(Constants.USER_SESSION,loginUser);
//頁面的跳轉
return "redirect:/frame";
}else {//用戶不存在
//使用request容器，返回一個提示信息
request.setAttribute("error","用戶名或者密碼錯誤");
//頁面的跳轉
return "login";
}
}
@RequestMapping("/frame")
public String frame(){
return "frame";
}
}
6 編寫Services層
注意要在applicationContext-mybaits.xml中注冊為javaBean
目錄結構
UserService接口
package com.test.service.user;
import com.test.entity.User;
public interface UserService {
User login(String userCode, String password);
}
UserServiceImpl實現
package com.test.service.user;
import com.test.controller.LoginController;
import com.test.dao.user.UserMapper;
import com.test.entity.User;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class UserServiceImpl implements UserService{
//log4j
private static final Logger logger1= Logger.getLogger(UserServiceImpl.class);
@Autowired
private UserMapper userMapper;
//登陸
@Override
public User login(String userCode, String password) {
logger1.debug("enter UserServiceImpl =====>login method param: userCode="+userCode
+" password= "+password);
User user = userMapper.getUserByUserCode(userCode);
logger1.debug("enter UserServiceImpl =====>login method " +
"return: user=:user.id"+user.getId()+
" user.userCode="+user.getUserCode()+
" user.userName="+user.getUserName());
if(user!=null && !user.getUserPassword().equals(password)){
//當用戶存在，但是密碼不一致，賦值為null
user=null;
}
return user;
}
}
7.編寫dao層
目錄結構
首先在applicationContext-mybaits.xml中將dao層的mapper注冊為javaBean,放在最后即可。
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.test.dao" />
</bean>
UserMapper接口
package com.test.dao.user;
import com.test.entity.User;
import org.apache.ibatis.annotations.Param;
public interface UserMapper {
//根據用戶名獲得用戶
public User getUserByUserCode(@Param("userCode") String userCode);
}
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.test.dao.user.UserMapper">
<!--根據用戶名獲得用戶-->
<select id="getUserByUserCode" parameterType="string" resultType="User">
select * from test_user
<where>
<if test="userCode!=null and userCode!=''">
userCode=#{userCode}
</if>
</where>
</select>
</mapper>
注意2 在pom的build中添加resource資源，否則會找不到mapper
<!-- 如果不添加此節點mybatis的mapper.xml文件都會被漏掉。 -->
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
</resources>
效果
初始界面 index.jsp
在地址欄輸入localhost:8080/test 進入登錄界面login.jsp
登錄成功
登錄失敗
