spring使用注解做Test测试类

package bos_management.standardRepositoryDemo;

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.itcast.bos.StandardRepository.base.StandardRepository;

//使用注解完成测试

@RunWith(SpringJUnit4ClassRunner.class)

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

public class StandardRepositoryTest {

@Autowired

private StandardRepository standardRepository;

//必须写@Test,不然会报没有运行方法的错误

@Test

public void testQuery(){

System.out.println(standardRepository.findById(2));

}

}
