Spring Boot学习笔记（六）整合Junit

第一步，在pom.xml文件中增加依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <version>2.1.1.RELEASE</version>
        </dependency>

第二步，准备好启动类

package org.test;

import org.springframework.boot.autoconfigure.SpringBootApplication; 
import org.springframework.boot.web.servlet.ServletComponentScan; 

@SpringBootApplication
@ServletComponentScan //扫描servlet注解
public class Application {

    public static void main(String[] args) {
        org.springframework.boot.SpringApplication.run(Application.class, args);
    }
 
}

第三步，新建测试类，并设置注解

@RunWith： 整合Junit与spring

@SpringBootTest：加载Spring Boot启动类

在方法上用加上@test注解就可以运行测试方法了

package org.test.test;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.test.Application;
import org.test.entity.TestTable;
import org.test.service.TestTableService;

import javax.annotation.Resource;
import java.util.List;

@RunWith(SpringJUnit4ClassRunner.class) //整合junit和spring环境整合
@SpringBootTest(classes = {Application.class}) //加载Spring Boot启动类
public class GeZhongTest {

    @Resource
    private TestTableService service;


    @Test
    public void test(){
        List<TestTable> list =  service.findAll();
        System.out.println(list.spliterator().toString()); 
    }

}

另：

要在控制台显示mybatis执行的sql语句的配置（application.yml）如下

logging:
  level:
     org.test.dao : debug
