在JUnit单元测试中获取bean

一、使用注解@Autowired注入bean

package test;
    
    import java.util.List;
    
    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 OThinker.H3.szmc.entities.ZjUsers;
    import OThinker.H3.szmc.service.EamifService;
    
    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration("classpath:./config/applicationContext.xml")
    public class SolinTest {
    	
    	@Autowired
    	private EamifService es;
    	
    	@Test
    	public void test() {
    		List<ZjUsers> zjUsersList = es.findZjUsersTheDay();
    		for(ZjUsers zjUsers : zjUsersList) {
    			System.out.println(zjUsers.getUsrCode()+"-------------"+zjUsers.getUsrDesc());
    		}
    	}
    }

二、通过ClassPathXmlApplicationContext得到ApplicationContext，再通过getBean获取bean

(但按照Spring的推荐，在单元测试时不应该依赖于Spring容器，也就是说不应该在单元测试时启动ApplicationContext并从中获取Bean，所以此种方法不推荐)

package test;
    
    import java.util.List;
    
    import org.junit.Test;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    import OThinker.H3.szmc.entities.ZjUsers;
    import OThinker.H3.szmc.service.EamifService;
    
    public class SolinTest {
    	ApplicationContext applicationContext = new ClassPathXmlApplicationContext("./config/applicationContext.xml");
    	
    	@Test
    	public void test() {
    		EamifService es = (EamifService)applicationContext.getBean(EamifService.class);
    		List<ZjUsers> zjUsersList = es.findZjUsersTheDay();
    		for(ZjUsers zjUsers : zjUsersList) {
    			System.out.println(zjUsers.getUsrCode()+"-------------"+zjUsers.getUsrDesc());
    		}
    	}
    }
