1-SpringBoot整合Junit搭建SpringBoot工程 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>
/**
* 测试类
*/
@RunWith(SpringRunner.class)
@SpringBootTest(classes = SpringbootJunitApplication.class )
public class UserServiceTest {
@Test
public void test(){
System.out.println(111);
}
}4.测试 2-SpringBoot整合mybatis①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 3-SpringBoot整合redis①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
