Spring测试代码讲解示例

本文主要是介绍Spring测试代码讲解示例，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1 Spring测试简介

测试时开发工作中不可缺少的部分，单元测试只针对当前开放的类和方法进行测试，可以简单通过模拟依赖来实现，对运行环境没有依赖，但是仅仅进行单元测试是不够的，它只能验证当前类或方法能否正常工作
Spring通过Spring TestContext Framework对基础测试提供顶级支持，它不依赖于特定的测试框架，可以使用junit，或者TestNG
Spring提供了一个SpringJUnit4ClassRunner类，它提供了Spring TestContext Framework的功能。通过@ContextConfiguration来配置Application Context，通过@ActiveProfiles确定活动的profile

2 Spring运行项目测试

2.1 pom.xml

		<dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>5.2.9.RELEASE</version><scope>compile</scope></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>5.2.9.RELEASE</version></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version></dependency>

2.2 测试实例bean

package cn.jzh.test;public class TestBean {private String msg;public TestBean(String msg){this.msg= msg;}public String getMsg() {return msg;}public void setMsg(String msg) {this.msg = msg;}
}

2.3 测试配置

package cn.jzh.test;import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Profile;
import org.springframework.test.context.ActiveProfiles;@Configurationpublic class TestConfig {@Bean@Profile("dev")public TestBean devTestBean(){return new TestBean("from dev profile");}@Bean@Profile("prod")public TestBean prodTestBean(){return new TestBean("from prod profile");}
}

2.4 测试运行类

package cn.jzh.test;import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;@RunWith(SpringJUnit4ClassRunner.class)//SpringJUnit4ClassRunner在junit环境下提供Spring TestContext Framework的功能
@ContextConfiguration(classes = {TestConfig.class})//用来加载配置applicationContext，其中classes属性用来加载配置类
@ActiveProfiles("dev")//用来声明活动的profile
public class TestMain {@Autowiredpublic TestBean bean;@Testpublic void pordBean(){String msg = bean.getMsg();System.out.println(msg);}
}

3 不运行项目测试

配置文件使用xml的话，就用ClassPathXmlApplicationContext读取配置文件来测试，如果用注解的话，就用AnnotationConfigApplicationContext

3.1 ClassPathXmlApplicationContext

在src下新建配置文件applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsd"><bean id="userinfoJdbcDao" class="cn.test.dao.impl.UserinfoJdbcDaoImpl"></bean>    <bean id="userinfoHibDao" class="cn.test.dao.impl.UserinfoHibDaoImpl"></bean>    <bean id="userinfoService" class="cn.test.service.impl.UserinfoServiceImpl"><property name="userinfoDao" ref="userinfoHibDao"></property></bean>
</beans>

测试

public class Test {public static void main(String[] args) {ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");UserinfoService userinfoService = applicationContext.getBean(UserinfoService.class,"userinfoService");Userinfo user = new Userinfo();user.setUserId(1);user.setUserName("test");user.setUserPass("test");userinfoService.save(user);}
}

3.2 AnnotationConfigApplicationContext

@Configuration
@ComponentScan("cn.jzh.aop")
@EnableAspectJAutoProxy//开启spring对aspectj代理的支持
public class AopConfig {
}

@Service
public class DemoMethodService {public void add(){System.out.println("service................");}
}

public class AopMain {public static void main(String[] args) {AnnotationConfigApplicationContext acac = new AnnotationConfigApplicationContext(AopConfig.class);DemoMethodService bean = acac.getBean(DemoMethodService.class);bean.add();acac.close();}
}
