spring4整合junit测试

1、加入依赖包

1.使用spring4的测试框架须要加入如下依赖包：

JUnit 4

spring-Test （Spring框架中的test包）

spring-aop(Spring框架中的AOP包,spring4整合junit测试须要依赖aop的包了)

使用maven，在基于spring的项目中添加以下依赖：

<dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>4.1.6.RELEASE</version>
        </dependency>
       <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-aop</artifactId>
            <version>4.1.6.RELEASE</version>
        </dependency>

2、建立测试类

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
@RunWith(SpringJUnit4ClassRunner.class) // 使用junit4进行测试
@ContextConfiguration(locations = "classpath:applicationContext.xml")//加载配置文件
public class Test1 {

}

解释所用到的注解

@RunWith 用于指定junit运行环境，是junit提供给其余框架测试环境接口扩展，为了便于使用spring的依赖注spring提供了org.springframework.test.context.junit4.SpringJUnit4ClassRunner做为Junit测试环境

@ContextConfiguration导入配置文件

若是只有一个配置文件

@ContextConfiguration(locations = "classpath:applicationContext.xml")

若是有多个配置文件

@ContextConfiguration(locations = { "classpath:/applicationContext1.xml", "classpath:/applicationContext2.xml" })

建立本身的测试类

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import cn.huafeng.servicetest.Car;

@RunWith(SpringJUnit4ClassRunner.class) // 使用junit4进行测试
@ContextConfiguration(locations = "classpath:applicationContext.xml")//加载配置文件
public class Test1 {

    @Autowired//spring自动注入
    Car car;

    @Test
    public void funTest(){
        System.out.println(car);
    }
}

控制台打印输出

log4j:WARN No appenders could be found for logger (org.springframework.test.context.junit4.SpringJUnit4ClassRunner).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

Car [name=咖菲猫, color=blue]

若是出现了这个异常

Causedby:java.lang.NoSuchMethodError:org.springframework.cache.ehcache.EhCacheFactoryBean.setMaxEntriesLocalHeap(J)V

请先注释掉，具体缘由尚未找到,也能够调其余版本
