Springboot2+thymeleaf+Jpa实现CRUD操作

1 引入pom依赖

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId>
</dependency>
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

2 配置yaml

spring:datasource:driver-class-name: com.mysql.cj.jdbc.Driverurl: jdbc:mysql://localhost:3306/musicblog?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=UTF-8&useSSL=false&allowPublicKeyRetrieval=trueusername: rootpassword: marlonjpa:hibernate:ddl-auto: noneshow-sql: truethymeleaf:cache: falsecheck-template-location: true  #check-tempate-location: 检查模板路径是否存在prefix: classpath:/template/suffix: .html

3 主启动类JpaApplication

@SpringBootApplication
public class JpaApplication{public static void main(String[] args) {SpringApplication.run(JpaApplication.class,args);}
}

4 新建表

DROP TABLE IF EXISTS `user`;
CREATE TABLE `user`  (`ID` varchar(64) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '主键',`PHONE` varchar(11) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '电话',`NAME` varchar(64) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,`AGE` varchar(3) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,PRIMARY KEY (`ID`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;
