14-SpringBoot整合Junit

1. 搭建SpringBoot工程

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>

3. 编写测试类

/**
 * 测试类
 */

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

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

4.测试

15-SpringBoot整合mybatis

①搭建SpringBoot工程

②引入mybatis起步依赖，添加mysql驱动

<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编写DataSource和MyBatis相关配置

application.yml

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


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

  # config-location:  # 指定mybatis的核心配置文件

④定义表和实体类

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

⑤编写dao和mapper文件/纯注解开发

编写dao

@Mapper
@Repository
public interface UserXmlMapper {

    public List<User> findAll();
}

mapper.xml

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

纯注解开发

@Mapper
@Repository
public interface UserMapper {

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

⑥测试

16-SpringBoot整合redis

①搭建SpringBoot工程

②引入redis起步依赖

  <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配置redis相关属性

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

④注入RedisTemplate模板

⑤编写测试方法，测试

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

    @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);
    }

}
