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 {@AutowiredUserService userService;@Testpublic 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;}@Overridepublic 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=UTCusername: rootpassword: rootdriver-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 {@Autowiredprivate UserMapper userMapper;@Testvoid 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;@Testvoid 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 {@Autowiredprivate RedisTemplate redisTemplate;@Testvoid testSet() {redisTemplate.boundValueOps("name").set("zhangsan");}@Testvoid 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ipport: 6379
