一、SpringBoot整合Junit

1.1 搭建SpringBoot工程

1.2 引入starter-test起步依赖

 <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

1.3 编写类

@Service
public class UserService {

    public void show(){
        System.out.println("这是Service里面的show....");
    }


}

1.4 测试

@RunWith(SpringRunner.class)
@SpringBootTest(classes = DemoJunitApplication.class )
public class UserServiceTest {

    @Autowired
    UserService service;

    @Test
    public void test(){
        System.out.println(111);
    }

    @Test
    public void test1(){
        service.show();
    }
}

二、SpringBoot整合mybatis

2.1 搭建SpringBoot工程

2.2 引入mybatis起步依赖，添加驱动

<dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.1.0</version>
        </dependency>

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <!--<scope>runtime</scope>-->
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <scope>test</scope>
        </dependency>

2.3 编写DataSource和MyBatis相关配置

spring:
  datasource:
    url: jdbc:mysql://192.168.147.128:3306/springboot?serverTimezone=UTC
    username: root
    password: 123456
    driver-class-name: com.mysql.cj.jdbc.Driver

2.4 定义表和实体类

CREATE DATABASE `springboot` ;
USE `springboot`;

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;

insert  into `t_user`(`id`,`username`,`password`) values (1,'zhangsan','123'),(2,'lisi','234');

实体类

public class User {

    private int id;
    private String username;
    private String 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 + '\'' +
                '}';
    }

}

2.5 编写dao和mapper文件/纯注解开发

2.5.1 纯注解开发

@Mapper
@Repository
public interface UserMapper {

    @Select("select * from t_user")
    public List<User> findAll();
}

2.5.2 配置mapper文件

@Mapper
@Repository
public interface UserXmlMapper {

    public List<User> findAll();

}

<?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.study.mapper.UserXmlMapper">
    <select id="findAll" resultType="user">
        select * from t_user
    </select>
</mapper>

配置文件添加一些修改

mybatis:
  mapper-locations: classpath:mapper/*Mapper.xml # mapper映射文件路径
  type-aliases-package: cn.study.domain

2.6 测试

@SpringBootTest
@RunWith(SpringRunner.class)
public class DemoMybatisApplicationTests {

    @Autowired
    private UserMapper userMapper;

    @Autowired
    private UserXmlMapper userXmlMapper;

    @Test
    public void testFindAll() {
        List<User> list = userMapper.findAll();
        System.out.println(list);
    }

    @Test
    public void testFindAll2() {
        List<User> list = userXmlMapper.findAll();
        System.out.println(list);
    }

}

三、SpringBoot整合redis

3.1 搭建SpringBoot工程

按照上一篇里面介绍的新建一个springboot项目或者是模块。

3.2 引入redis起步依赖

在pom.xml里面添加依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

3.3 配置redis相关属性

在resource文件下，application.yml文件里面添加配置参数，如果文件不存在则新建

spring:
  redis:
    host: 127.0.0.1
    port: 6379

3.4 注入RedisTemplate模板

@Autowired
    private RedisTemplate redisTemplate;
    

3.5 编写测试方法，测试

在测试文件夹下编写测试

@RunWith(SpringRunner.class)
@SpringBootTest
public class DemoRedisApplicationTests {

    @Autowired
    private RedisTemplate redisTemplate;

    @Test
    public void testSet() {
        //存入数据
        redisTemplate.boundValueOps("name").set("zhangsan");
    }

    @Test
    public void testGet() {
        //获取数据
        Object name = redisTemplate.boundValueOps("name").get();
        System.out.println(name);
    }

}
