SpringBoot第二次課---SpringBoot+thymeleaf+MyBatis+MySQL實現查詢功能

數據庫操作

測試數據

DROP TABLE IF EXISTS `t_book`;

CREATE TABLE `t_book` (

  `id` int(11) NOT NULL AUTO_INCREMENT,

  `isbn` varchar(9) DEFAULT NULL,

  `author` varchar(50) DEFAULT NULL,

  `name` varchar(100) DEFAULT NULL,

  `price` float DEFAULT NULL,

  PRIMARY KEY (`id`)

) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8;      

        

        

INSERT INTO `t_book` VALUES ('1', '11111', '吳承思', '西遊記', '100');

INSERT INTO `t_book` VALUES ('2', '22222', '羅貫中', '三國演義', '200');

INSERT INTO `t_book` VALUES ('3', '33333', '施耐奄', '水滸傳', '200');

INSERT INTO `t_book` VALUES ('4', '44444', '曹雪芹', '紅樓夢', '200');

INSERT INTO `t_book` VALUES ('5', '55555', '吳道子', '天王送子圖', '3000');

INSERT INTO `t_book` VALUES ('6', '66666', '李白', '靜夜思', '2000');

INSERT INTO `t_book` VALUES ('7', '77777', '杜甫', '茅屋爲秋風所破歌', '4000');

INSERT INTO `t_book` VALUES ('8', '88888', '白居易', '長恨歌', '2000');    

 

• 整合Mybaits

第一步：添加相關依賴

 

JDBC API

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>

MySQL Driver

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <scope>runtime</scope>
</dependency>

MyBatis Framework

<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.1.1</version>
</dependency>

Thymeleaf

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

 

第二步：配置application.properties

#端口

server.port=9999

#驅動

spring.datasource.driver-class-name=com.mysql.jdbc.Driver

#url

spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8

#用戶名

spring.datasource.username=root

#密碼

spring.datasource.password=52Java

#掃描mapper文件 com.hr.mapper

mybatis.mapper-locations=classpath*:com/hr/mapper/*.xml

第三步：

寫後臺並測試

寫bean

寫mapper

寫mapper.xml

寫service

寫serviceimpl

寫web

第四步：寫前臺並測試

Thymeleaf標籤使用

th:each

th:text

th:href

@ PathVariable

value,修改的回顯

th:value="${o.productDesc}"

 

option回顯

th:selected="${digit.type=='手機' ? true:false}"

隔行換色

寫模板list.html

 

寫模板add.html

寫模板update.html

 

測試：

預計問題：

1.mysql驅動、mysql的url

• spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
• You must configure either the server or JDBC driver (via the 'serverTimezone' configuration property) to use a more specifc time zone value if you want to utilize time zone support. 
• serverTimezone=UTC
• 共7種，分別是白色，淺藍色，深藍色，綠色，黃色，紅色，黑色，對應的class爲btn，btn btn-primary，btn btn-info，btn btn-success，btn btn-warning，btn btn-danger，btn btn-inverse。
