Java之Spring Boot入门到精通【IDEA版】SpringBoot整合其他框架
[](()2、引入redis起步依赖
- 通过上述的自动创建的工程redis的依赖已经自动添加好
[](()3、在测试方法当中默认连接本地的redis数据库
不需要配置如何信息
package cn.itbluebox.springbootredis;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.BoundValueOperations;
import org.springframework.data.redis.core.RedisTemplate;
@SpringBootTest
class SpringbootRedisApplicationTests {
@Autowired
private RedisTemplate redisTemplate;
@Test
void testSet() {
//存入数据
redisTemplate.boundValueOps(“name”).set(“张三”);
}
@Test
void testGet() {
//获取数据
Object name = redisTemplate.boundValueOps(“name”).get();
System.out.println(name);
}
}
- 启动redis
- 运行测试类（测试方法testSet()存入数据）
- 运行测试类（测试方法testGet()获取数据）
[](()4、配置redis相关属性
spring:
redis:
host: 127.0.0.1 #redis的主机地址
port: 6379
- 运行测试
[](()三、SpringBoot整合MyBatis
[](()1、搭建SpringBoot工程
[](()2、引入mybatis起步依赖,添加mysq|驱动
通过上述的工程搭建自动添加好了依赖
[](()3、定义表和实体类
- 创建数据库
CREATE DATABASE /!32312 IF NOT EXISTS/springboot /*!40100 DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci */;
USE springboot;
/*Table structure for table t_user */
DROP TABLE IF EXISTS t_user;
CREATE TABLE t_user (
id int(11) NOT NULL AUTO_INCREMENT,
username varchar(32) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
password varchar(32) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
PRIMARY KEY (id)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
/*Data for the table t_user */
insert into t_user(id,username,password) values (1,‘zhangsan’,‘123’),(2,‘lisi’,‘234’);
- 创建实体类
package cn.tbluebox.springbootmybatis.domain;
public class User {
private int id;
private String username;
private String password;
public User() {
}
public User(int id, String username, String password) {
this.id = id;
this.username = username;
this.password = password;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@Override
public String toString() {
return “User{” +
“id=” + id +
“, username='” + username + ‘’’ +
“, password='” + password + ‘’’ +
‘}’;
}
}
[](()4、编写DataSource和MyBatis相关配置
#datasource
spring:
datasource:
url: jdbc:mysql:///springboot
username: root
password: root
driver-class-name: com.mysql.jdbc.Driver
[](()5、编写dao和mapper文件/纯注解开发
package cn.tbluebox.springbootmybatis.mapper;
import cn.tbluebox.springbootmybatis.domain.User;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;
import java.util.List;
@Mapper
@Repository
public interface UserMapper {
@Select(“select * from t_user”)
public List findAll();
}
[](()6、测试
package cn.tbluebox.springbootmybatis;
import cn.tbluebox.springbootmybatis.domain.User;
import cn.tbluebox.springbootmybatis.mapper.UserMapper;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import java.util.List;
@SpringBootTest
class SpringbootMybatisApplicationTests {
@Autowired
private UserMapper userMapper;
@Test
void findAllUser() {
List all = userMapper.findAll();
System.out.println(all);
}
}
运行测试类
[](()7、编写dao和mapper文件/XML开发
[](()（1）创建UserXmlMapper接口
package cn.tbluebox.springbootmybatis.mapper;
import cn.tbluebox.springbootmybatis.domain.User;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;
import java.util.List;
@Mapper
@Repository
public interface UserXmlMapper {
public List findAll();
}
[](()（2） 编写配置文件
select * from t_user
[](()（3） 配置配置文件
#datasource
spring:
datasource:
url: jdbc:mysql:///springboot
username: root
password: root
driver-class-name: com.mysql.jdbc.Driver
mybatis
mybatis:
mapper-locations: classpath:mapper/*Mapper.xml #mapper映射文件的路径
type-aliases-package: cn.tbluebox.springbootmybatis.domain
config-location: #指定mybatis核心配置文件
[](()（4）完善测试类
package cn.tbluebox.springbootmybatis;
import cn.tbluebox.springbootmybatis.domain.User;
import cn.tbluebox.springbootmybatis.mapper.UserMapper;
import cn.tbluebox.springbootmybatis.mapper.UserXmlMapper;
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
