Junit测试是很方便的，本博客记录一下Junit测试一些Service接口的方法，这样可以不运行项目，在@Test注解的方法里直接测试

Maven引入jar包：

<properties>
    		
    		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    		
    		<junit.version>4.12</junit.version>
    </properties>
    <dependencies>	
    		
    		<dependency>
    			<groupId>junit</groupId>
    			<artifactId>junit</artifactId>
    			<version>${junit.version}</version>
    			<scope>test</scope>
    		</dependency>
    </dependencies>

*  方法一、IOC方法  
    通过ApplicationContext，ioc的方法来获取对应的bean

import org.junit.Before;
    import org.junit.Test;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    public class MyTest {
    
    	private ApplicationContext applicationContext;
    
    	@Before
    	public void setUp() throws Exception {
    		applicationContext = new ClassPathXmlApplicationContext(
    				"classpath:spring/spring-context.xml");
    	}
    
    	@Test
    	public void test1(){
    		UnitService unitService = (UnitService) applicationContext
    				.getBean("unitService");
    		UnitModel unitdto = new UnitModel();
    		unitdto.setUnitCode("15524");
    		UnitModel unitvo = unitService.loadOneUnit(unitdto);
    		if(unitvo != null) {
    			String unitName = unitvo.getUnitName();
    			System.out.println(unitName);
    		}
    	}
    }

*  方法二：注解方式  
    主要通过SpringJUnit4ClassRunner这个类，同样也要通过ContextConfiguration获取对应的spring-context配置

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;
    
    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration(locations = {"classpath:spring/spring-context.xml"})
    public class MyTest {
    
    	@Autowired
    	UnitService unitService;
    
    	@Test
    	public void test1(){
    		UnitModel unitdto = new UnitModel();
    		unitdto.setUnitCode("15524");
    		UnitModel unitvo = unitService.loadOneUnit(unitdto);
    		if(unitvo != null) {
    			String unitName = unitvo.getUnitName();
    			System.out.println(unitName);
    		}
    	}
    }
