整合Junit

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

package com.example.test;


import com.example.springbootinit.SpringbootInitApplication;
import com.example.springbootinit.service.UserService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.junit4.SpringRunner;

@SpringBootTest(classes = SpringbootInitApplication.class)
@RunWith(SpringRunner.class)

//如果测试类所在包是在当前对应启动类所在包或子包时不用指定启动类
//@RunWith(SpringJUnit4ClassRunner.class)
//@SpringBootTest

//@SpringBootTest 不会加载spring容器
public class SpringbootInitApplicationTests {

    @Autowired
    private UserService userService;

    @Test
    public void test1() {
        System.out.println(userService);
    }

}

整合Mybatis

        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>1.3.2</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jdbc</artifactId>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.47</version>
<!--            <scope>runtime</scope>-->
        </dependency>

注解使用

@Mapper
public interface UserMapper {

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

xml使用

@Mapper
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="com.example.springbootinit.mapper.UserXmlMapper">
    <select id="findall" resultType="user">
        select * from testdb.t_user
    </select>
</mapper>

配置

spring:
  profiles:
    active: dev

  ## mybatis
  ## mybatis
  ## mybatis
  datasource:
    url: jdbc:mysql:///testdb
    username: iplat62
    password: iplat62
    driver-class-name: com.mysql.jdbc.Driver

# mybatis
# mybatis
# mybatis
mybatis:
  mapper-locations: classpath:mapper/*Mapper.xml  # mapper 映射文件路径
  type-aliases-package: com.example.springbootinit.domain  # 别名
  # config-location: # 指定mybatis核心配置文件

配置映射文件扫描

@MapperScan("com.example.springbootinit.mapper")

整合Redis
