[Spring]简单Junit和Spring整合配置

首先采用了maven来部署所需要的jar包依赖

这里需要srping-context.jar,spring-test.jar,junit.jar,log4j.jar

	<dependencies>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-context</artifactId>
			<version>4.2.5.RELEASE</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-test</artifactId>
			<version>4.2.5.RELEASE</version>
		</dependency>
		<dependency>
			<groupId>junit</groupId>
			<artifactId>junit</artifactId>
			<version>4.12</version>
			<scope>test</scope>
		</dependency>
		<dependency>
			<groupId>log4j</groupId>
			<artifactId>log4j</artifactId>
			<version>1.2.14</version>
		</dependency>

log4j.properties配置 放在classpath下

log4j.rootCategory=INFO, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %t %c{2}:%L - %m%n
log4j.category.org.springframework.beans.factory=DEBUG

新建一个AppConfig类

com.domain里面包括了各种需要的bean，besePackages是一个数组，所以可以提供多个包

@ImportResource 是部分的xml配置，这里由于很大程度上使用了anotation配置，所以xml文件里面并没有什么东西。

@Profile的作用在于如果在开发时进行一些数据库测试，希望链接到一个测试的数据库，以避免对开发数据库的影响。

@Configuration
@ComponentScan(basePackages = "com.domain")
@ImportResource(value = "TestCase_01.xml")
public class AppConfig {
	@Bean(name = "dbService")
	@Profile("dev")
	public DBService mockDBService(){
		return new MockDBService();
	}
	
	@Bean(name = "dbService")
	@Profile("rc")
	public DBService MysqlDBService(){
		return new MysqlDBService();
	}

}

在单元测试类里面

在使用所有注释前必须使用@RunWith(SpringJUnit4ClassRunner.class),让测试运行于Spring测试环境 

@ContextConfiguration是注册配置，这里可以是特定java配置类 也可以配置xml路径

由于需要ApplicationContext 所以添加了一个属性，通过@Autowired让spring容器来自动转配

@ActiveProfiles激活某个测试方案

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AppConfig.class)
@ActiveProfiles("dev")
public class TestCase_01 {
	@Autowired
	private ApplicationContext ctx;

	@Test
	public void test_case_011() {
		ClientService staticClientService = ctx.getBean("staticClientService", ClientService.class);
		ClientService noneStaticClientService = ctx.getBean("noneStaticClientService", ClientService.class);
		System.out.println(staticClientService);
		System.out.println(noneStaticClientService);
	}

	@Test
	public void test_case012() {
		SimpleMovieLister s01 = ctx.getBean("movieListerWithConstructor", SimpleMovieLister.class);
		SimpleMovieLister s02 = ctx.getBean("movieListerWithProperty", SimpleMovieLister.class);
		assertNotNull(s01);
		assertNotNull(s02);
		assertNotNull(s01.getMovieFinder());
		assertNotNull(s02.getMovieFinder());
	}

	@Test
	public void profileTest() {
		DBService dbService = ctx.getBean(DBService.class);
		assertEquals(3, dbService.count("select * from users"));
	}
}
