springboot整合mybatis plus与druid详情

加坐标可以使用https://mvnrepository.com/来查找

先加以下坐标：

使用的数据库介绍：

配置连接数据库：

spring:
 datasource:
   driver-class-name: com.mysql.cj.jdbc.Driver
   url: jdbc:mysql://localhost:3306/spring?serverTimezone=UTC
   username: root
   password: 123456

定义类：

package com.spring1.domain;

import com.baomidou.mybatisplus.annotation.TableName;

@TableName("student")
public class student {
   private Integer id;
   private String name;
   private String age;

@Override
   public String toString() {
       return "student{" +
               "id=" + id +
               ", name='" + name + '\'' +
               ", age='" + age + '\'' +
               '}';
   }

public Integer getId() {
       return id;
   }

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

public String getName() {
       return name;
   }

public void setName(String name) {
       this.name = name;
   }

public String getAge() {
       return age;
   }

public void setAge(String age) {
       this.age = age;
   }
}

测试：

package com.spring1;

import com.spring1.dao.StudentDao;
import com.spring1.domain.student;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class Spring1ApplicationTests {

@Autowired
   private StudentDao studentDao;
   @Test
   void contextLoads() {
       System.out.println(studentDao.selectList(null));
   }

}

[student{id=1000, name='Li Ming', age='22'}, student{id=1001, name='Danny', age='17'}, student{id=1002, name='Li Gang', age='22'}, student{id=1003, name='Jenny', age='19'}, student{id=1004, name='Jim', age='19'}]

添加druid

添加坐标：

配置修改：

spring:
 datasource:
   druid:
      driver-class-name: com.mysql.cj.jdbc.Driver
      url: jdbc:mysql://localhost:3306/spring?serverTimezone=UTC
      username: root
      password: 123456
