1.创建项目，编写pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0"
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    	<modelVersion>4.0.0</modelVersion>
    	<parent>
    		<groupId>org.springframework.boot</groupId>
    		<artifactId>spring-boot-starter-parent</artifactId>
    		<version>1.5.2.RELEASE</version>
    
    	</parent>
    	<groupId>per.czt</groupId>
    	<artifactId>19-spring-boot-junit</artifactId>
    	<version>0.0.1-SNAPSHOT</version>
    	<packaging>jar</packaging>
    
    	<name>19-spring-boot-junit</name>
    	<url>http://maven.apache.org</url>
    
    	<properties>
    		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    	</properties>
    
    	<dependencies>
    
    
    		
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-web</artifactId>
    		</dependency>
    		
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-test</artifactId>
    		</dependency>
    	</dependencies>
    </project>

2.编写dao层，和service层和启动类  
UserDaoImpl.class

package per.czt.dao;
    
    import org.springframework.stereotype.Repository;
    
    @Repository
    public class UserDaoImpl {
    
    	public void saveUser() {
    		System.out.println("insert into user.");
    	}
    }

UserServiceImpl.class

package per.czt.service;
    
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;
    
    import per.czt.dao.UserDaoImpl;
    
    @Service
    public class UserServiceImpl {
    	@Autowired
    	private UserDaoImpl userDaoImpl;
    	public void addUser() {
    		userDaoImpl.saveUser();
    	}
    
    }

App.class

package per.czt;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    /**
     * Hello world!
     *
     */
    @SpringBootApplication
    public class App 
    {
        public static void main( String[] args )
        {
            SpringApplication.run(App.class, args);
        }
    }

3.编写junit测试类

package per.czt.test;
    
    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;
    /*
     * 
     * SpringBoot启动器
     * @RunWith:启动器
     * SpringJUnit4ClassRunner.class:让junit与springboot整合
     * @SpringBootTest:1.当前类为SpringBoot启动类2.加载SpringBoot的启动类，启动SpringBoot
     * 
     * junit与spring整合@Contextconfigutaion("class:applicationContext.xml")
     */
    
    import per.czt.App;
    import per.czt.service.UserServiceImpl;
    @RunWith(SpringJUnit4ClassRunner.class)
    @SpringBootTest(classes= {App.class})
    public class UserServiceTest {
    	@Autowired
    	private UserServiceImpl userServiceImpl;
    	@Test
    	public void testAddUser() {
    		this.userServiceImpl.addUser();
    	}
    }
