目录

一、SpringBoot整合Junit

🍀（1）搭建SpringBoot工程 springboot-test，不用任何起步依赖

🍀（2）引入starter-test起步依赖

pom.xml:

<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>

🍀（3）编写service:com.wang.springboottest

@Service 
public class UserService {
    
    public void add() {
    
        System.out.println("add..........."); 
    } 
}

🍀（4）编写测试类: com.wang.springboottest

@SpringBootTest
@RunWith(SpringRunner.class)
public class UserServiceTest {
   
    @Autowired
    UserService userService;

    @Test
    public void testAdd() {
   
        userService.add();
    }
}

🍀（5）测试

二、SpringBoot整合Mybatis

🍀（1）搭建SpringBoot工程 springboot-mybatis

🍀（2）引入mybatis起步依赖，添加mysql驱动

pom.xml:

<dependencies>
        <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>
    </dependencies>

 

  
 

🍀（3）定义表和实体类: com.wang.springbootmybatis.domain

User.java:

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 + '\'' +
                '}';
    }
}

 

  
 

🍀（4）编写DataSource和MyBatis相关配置

application.yml:

# datasource
spring:
  datasource:
    url: jdbc:mysql://127.0.0.1:3306/springboot?serverTimezone=UTC
    username: root
    password: root
    driver-class-name: com.mysql.jdbc.Driver

🍀（5）纯注解开发 新建接口com.wang.springbootmybatis.mapper

@Mapper
public interface UserMapper {
   

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

🍀（6）测试

@SpringBootTest
class SpringbootMybatisApplicationTests {
   
    @Autowired
    private UserMapper userMapper;
    
    @Test
    void testFindAll() {
   
        List<User> all = userMapper.findAll();
        System.out.println(all);
    }
}

🍀（7）xml开发:新建接口 com.wang.springbootmybatis.mapper

@Mapper
public interface UserXmlMapper {
   
    public List<User> findAll();
}

resources下建立xml文件: UserMapper.xml

<?xml version="1.0" encoding="UTF8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.wang.mapper.UserXmlMapper">
    <select id="findAll" resultType="com.wang.domain.User">
        select * from t_user
    </select>
</mapper>

修改application.yml 新增如下配置:

mybatis:
  mapper-locations: classpath:mapper/*
  type-aliases-package: com.wang.springbootmybatis.domain

🍀（8）测试

@Autowired
private UserXmlMapper userXmlMapper;

    @Test
    void testFindAllByXml() {
   
        List<User> all = userXmlMapper.findAll();
        System.out.println(all);
    }

三、SpringBoot整合Redis

🍀（1）搭建SpringBoot工程: springboot-redis

🍀（2）引入redis起步依赖

pom.xml:

 <dependencies>
        <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>
 </dependencies>

🍀（3）编写测试类

@SpringBootTest
class SpringbootRedisApplicationTests {
   
    @Autowired
    private RedisTemplate redisTemplate;

    @Test
    void testSet() {
   
        redisTemplate.boundValueOps("name").set("zhangsan");
    }

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

 

  
 

🍀（4）启动redis

🍀（5）测试

🍀（6）application.yml 配置redis相关属性

spring:
  redis:
    host: 127.0.0.1 # redis的主机ip
    port: 6379
