springboot测试&启动类

测试

1. 引入依赖

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

2. 在 test 目录下创建测试类
   

3. 为测试类增加 @RunWith(SpringRunner.class) 和 @SpringBootTest 注解

4. 使用 @Autowired 注入待测试类的对象

5. 编写测试方法，增加 @Test 注解

package com.zhiyou100.dao;

import com.zhiyou100.entity.User;
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.SpringRunner;

/**
 * @author zhangfan
 * @date 2019/10/21
 */
@RunWith(SpringRunner.class)
@SpringBootTest
public class UserDaoTest {

    @Autowired
    private UserDao userDao;

    @Test
    public void testFindByAccount(){
        User zhangsan = userDao.findByAccount("zhangsan");

        System.out.println(zhangsan);
    }
}

启动类

package com.zhiyou100;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

/**
 * @author zhangfan
 * @date 2019/10/18
 */
@SpringBootApplication
@MapperScan("com.zhiyou100.dao")   //为dao接口生成代理类，扫描dao接口的文件位置
public class AuthApplication {

    public static void main(String[] args) {
        SpringApplication.run(AuthApplication.class,args);
    }
}
