Spring-boot整合junit测试

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>
  	<!-- springBoot的启动器 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <!-- springBoot的启动器 -->
     <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
