springboot+mybatis+mysql+druid监听
前言：
springboot 可以整合mybatis进行对数据库的持久化操作，连接mysql数据库（通过注解方式），同时配置druid监听，通过druid面板，可以知道sql语句的具体操作和所用时间。
同时，在整理这个文章时，是通过借鉴了很多大佬的分享。
具体配置
pom.xml 所需的依赖
需要添加连接mysql数据库的依赖；数据库连接池druid的依赖；springboot整合mybatis的依赖。
<!--连接mysql数据库-->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
<!--链接池配置 阿里巴巴连接驱动 -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid-spring-boot-starter</artifactId>
<version>1.1.13</version>
</dependency>
<!--引入mybatis-->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>2.1.0</version>
</dependency>
application.properties配置
需要配置连接mysql数据库的操作，及配置数据库连接池
#连接mysql数据库
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf8 &serverTimezone=Asia/Shanghai
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
#不使用默认的配置源
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.initialSize=2
spring.datasource.minIdle=1
spring.datasource.maxActive=20
spring.datasource.maxWait=60000
#打印sql语句
mybatis.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl
配置driud监听sql语句
import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class DruidConfiguration {
@Bean
public ServletRegistrationBean druidServlet() {
ServletRegistrationBean servletRegistrationBean=new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
// IP白名单 (没有配置或者为空，则允许所有访问)
servletRegistrationBean.addInitParameter("allow", "");
// IP黑名单(共同存在时，deny优先于allow)
servletRegistrationBean.addInitParameter("deny", "192.168.1.100");
//控制台管理用户
servletRegistrationBean.addInitParameter("loginUsername", "admin");
servletRegistrationBean.addInitParameter("loginPassword", "admin");
//是否能够重置数据 禁用HTML页面上的“Reset All”功能
servletRegistrationBean.addInitParameter("resetEnable", "false");
return servletRegistrationBean;
}
/**
* druid过滤器.
* @return
*/
@Bean
public FilterRegistrationBean filterRegistrationBean() {
FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter());
//添加过滤规则.
filterRegistrationBean.addUrlPatterns("/*");
//添加不需要忽略的格式信息.
filterRegistrationBean.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
return filterRegistrationBean;
}
}
项目其余代码及结构
项目简单结构
实体类
可以通过lombok依赖来减少代码的工作量
<!--作用于实体类，自动封装get，set方法-->
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.16.10</version>
</dependency>
通过@Data注解，自动封装get，set，toString方法等，非常方便
import lombok.Data;
@Data
public class Tuser {
private Integer id;
private String name;
private String phone;
private String uuid;
private String pwd;
}
数据库设计
CREATE TABLE `t_user` (
`id` int(10) NOT NULL AUTO_INCREMENT,
`phone` varchar(11) DEFAULT NULL COMMENT '手机号',
`name` varchar(50) DEFAULT NULL COMMENT '姓名',
`uuid` varchar(64) DEFAULT NULL COMMENT '盐',
`pwd` varchar(64) DEFAULT NULL COMMENT '密码',
PRIMARY KEY (`id`),
UNIQUE KEY `t_user_uq_phone` (`phone`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=18 DEFAULT CHARSET=utf8mb4;
INSERT INTO `t_user` VALUES ('2', '11111111111', '钟花花', 'ff12a6e6-3e7f-4ba9-a55b-ef0d0532ba2d', '827bdbb0227bbdad3cb159c01662e311');
INSERT INTO `t_user` VALUES ('3', '13236170925', '敏敏特穆尔', '0ce101df-b9e2-47ad-b279-122107c4ff0a', '6738b1739ff9d78855a241ebb0665a3e');
INSERT INTO `t_user` VALUES ('4', '13479769366', '张无忌', 'bab88b92-3b99-4a8d-a778-f3219af24718', '25b22e9c8a167b55ca29d9ae5b47afb2');
INSERT INTO `t_user` VALUES ('16', '12345678915', '钟花花', '1bb089eb-5ccc-4b29-8237-817d640a1422', '6ea0b946626ebd7303d990a6482908e4');
INSERT INTO `t_user` VALUES ('17', '12345678912', '钟花花', 'da7557ea-b1ce-4645-a8ea-5b930ff3f6ec', '5935a84675e16546e43634d977ecadb9');
与数据库交互的部分（mybatis）
@Repository
public interface TuserDao {
//查看所有Tuser信息
@Select("select * from t_user")
List<Tuser> getListOfTuser();
//根据id查找Tuser对象
@Select("select * from t_user where id=#{id}")
Tuser getTuserById(Integer id);
//修改
@Update("update t_user set name=#{name},phone=#{phone},uuid=#{uuid},pwd=#{pwd} where id=#{id}")
int UpdateByTuser(Tuser tuser);
}
service部分就粘贴出来了 ，直接上控制层部分
@RestController
@RequestMapping("/tuser/")
public class TuserController {
@Autowired
private TuserService tuserServiceimpl;
@GetMapping("getListOfTuser")
public Object getListOfTuser(){
List<Tuser> list=tuserServiceimpl.getListOfTuser();
return list;
}
@GetMapping("getTuserById")
public Object getTuserById(Integer id){
Tuser tuser=tuserServiceimpl.getTuserById(id);
return tuser;
}
@GetMapping("UpdateByTuser")
public Object UpdateByTuser(){
Tuser tuser=new Tuser();
tuser.setId(2);
tuser.setName("钟花花");
tuser.setPhone("11111111111");
tuser.setPwd("123456");
tuser=getMd5(tuser);
int num=tuserServiceimpl.UpdateByTuser(tuser);
return "成功修改的个数"+num;
}
public Tuser getMd5(Tuser tuser){
String pwd=tuser.getPwd();
//生成uuid
String uuid= String.valueOf(UUID.randomUUID());
tuser.setUuid(uuid);
//springboot自带的md5加密工具
String md5Password = DigestUtils.md5DigestAsHex((uuid+pwd).getBytes());
tuser.setPwd(md5Password);
return tuser;
}
}
结果显示
在浏览器上输入：http://localhost:8080/druid/login.html 就可以看到druid面板的登录界面
输入账号密码就可以登录：密码：admin 账号：admin
可在DruidConfiguration .java中修改
servletRegistrationBean.addInitParameter("loginUsername", "admin");
servletRegistrationBean.addInitParameter("loginPassword", "admin");
登录之后可看到
