SpringBoot整合其他框架【Junit,Redis,MyBatis】
一、SpringBoot整合Junit
①搭建SpringBoot工程
②引入starter-test起步依赖
- 快速构建的spring项目自动以及引入了spring-test的依赖
③编写测试类
- 并且也自动写了test类,但是为了方便演示,现在将下面对应的内容删除
- 删除成功
(1)在启动类傍边其他类
- UserService
package cn.itbluebox.springboottest;
import org.springframework.stereotype.Service;
@Service
public class UserService {
public void add(){
System.out.println("add...");
}
}
- 创建测试类
④添加测试相关注解
- 引入junit的依赖
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<scope>test</scope>
</dependency>
● @RunWith(SpringRunner.class)
● @SpringBootTest(clasSes =启动类.class)
package cn.itbluebox.test;
/*
userService的测试类
*/
import cn.itbluebox.springboottest.SpringbootTestApplication;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
@RunWith(SpringRunner.class)
@SpringBootTest(classes = SpringbootTestApplication.class)
public class UserServiceTest {
}
⑤编写测试方法
package cn.itbluebox.test;
/*
userService的测试类
*/
import cn.itbluebox.springboottest.SpringbootTestApplication;
import cn.itbluebox.springboottest.UserService;
import org.junit.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;
@RunWith(SpringRunner.class)
@SpringBootTest(classes = SpringbootTestApplication.class)
public class UserServiceTest {
@Autowired
private UserService userService;
@Test
public void test(){
userService.add();
}
}
- 运行测试
- 运行成功
- 如果主包和测试包的目录结构是相同的则
@SpringBootTest(classes = SpringbootTestApplication.class)
不需要写当中的classes
- 将UserServiceTest类移动到springboottest包当中
package cn.itbluebox.springboottest;
/*
userService的测试类
*/
import cn.itbluebox.springboottest.SpringbootTestApplication;
import cn.itbluebox.springboottest.UserService;
import org.junit.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;
@RunWith(SpringRunner.class)
@SpringBootTest
public class UserServiceTest {
@Autowired
private UserService userService;
@Test
public void test(){
userService.add();
}
}
- 运行测试
二、SpringBoot整合Redis
1、搭建SpringBoot工程
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<User> 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<User> 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<User> findAll();
}
(2) 编写配置文件
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="cn.tbluebox.springbootmybatis.mapper.UserXmlMapper">
<select id="findAll" resultType="user">
select * from t_user
</select>
</mapper>
(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.<以上是关于Java之Spring Boot入门到精通IDEA版SpringBoot整合其他框架Junit,Redis,MyBatis(一篇文章精通系列)中的主要内容,如果未能解决你的问题,请参考以下文章
