**Spring-boot整合junit测试**  
1.新建maven项目 添加依赖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>1.5.10.RELEASE</version>
      </parent>
      <groupId>com.bjsxt</groupId>
      <artifactId>18-spring-boot-exception5</artifactId>
      <version>0.0.1-SNAPSHOT</version>
      
      <properties>
      <java.version>1.7</java.version>
      <thymeleaf.version>3.0.2.RELEASE</thymeleaf.version>
      <thymeleaf-layout-dialect.version>2.0.4</thymeleaf-layout-dialect.version>
      </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.编写数据访问层dao

package cn.zds.dao;
    
    import org.springframework.stereotype.Repository;
    
    @Repository //把该类注册到spring bean
    public class UserDaoImpl {
    	public void insertUsers() {
    		System.out.println("insert into users......");
    	}
    }

3.编写业务层service

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

4.编写启动器

package cn.zds;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    
    @SpringBootApplication
    public class App {
    
    	public static void main(String[] args) {
    		SpringApplication.run(App.class, args);
    	}
    }

5.在src/test/java下新建Test类

package cn.zds.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;
    
    import cn.zds.App;
    import cn.zds.service.UserServiceImpl;
    
    
    /**
     * @RunWith作用 ： 启动器， 让junit跟spring环境整合
     * @SpringBootTest作用：1.标记当前类为测试类
     * 					  2.加载spring-boot启动类，启动spring-boot
     *
     */
    @RunWith(value=SpringJUnit4ClassRunner.class)
    @SpringBootTest(classes={App.class})
    public class UserServiceTest {
    	
    	@Autowired
    	private UserServiceImpl userServiceImpl;
    	
    	@Test  //开启测试
    	public void testAddUser() {
    		userServiceImpl.addUser();
    	}
    }

6.项目结构
