ssm整合
阅读原文请访问我的博客brightloong's blog
SSM框架,既是Sping + Spring MVC + Mybatis,本篇博文主要是作为本人的备忘,记录如何整合SSM框架,以及如何集成单元测试,关于每一个配置的作用大都加上了注释,至于如何搭建项目这里不在赘述(我使用的是web项目),可以自己查找相关资料。我使用的Spring版本是4.1.3.RELEASE,Mybatis版本是3.3.0,使用Maven进行构建。
注意:首先申明如下的配置是根据我的目录结构来配置的,我的目录结构如下所示:
目录结构
使用Maven添加相关jar包。
关于pom.xml的配置如下。

SSM整合配置
为了使配置层次清楚,结构清晰,我把配置按照web、service和dao分别分为spring-web.xml、spring-service.xml和spirng-dao.xml,下面依次介绍这几个配置文件。
spring-web.xm配置
该配置中主要是一些资源映射的相关配置。

<!-- 配置springMVC -->

<!-- 1.开启springMVC注解模式 -->

<!-- 简化配置:
-
1)自动注册defaultAnnotationHandlerMapping,AnnotationMethodHandlARadpter

<!--2.servelt-mapping 映射路径:"/"

静态资源默认servlet配置
-
1.加入对静态资源的处理:js,gif,png

在上述配置中最后关于获取properties的配置,我创建了一个PropertyUtil类用来获取properties文件,并读取里面的属性。PropertyUtil.java如下:
-
public class PropertyUtil extends PropertyPlaceholderConfigurer {
-
private static Map<String,String> propertyMap;
-
@Override
-
protected void processProperties(ConfigurableListableBeanFactory beanFactoryToProcess, Properties props) throws BeansException {
-
super.processProperties(beanFactoryToProcess, props);
-
propertyMap = new HashMap<String, String>();
-
for (Object key : props.keySet()) {
-
String keyStr = key.toString();
-
String value = props.getProperty(keyStr);
-
propertyMap.put(keyStr, value);
-
}
-
}
-
//static method for accessing context properties
-
public static Object getProperty(String name) {
-
return propertyMap.get(name);
-
}
-
}

单元测试集成
在pom.xm文件中我们曾加入如下的jar包用来做单元测试。
-
<!-- 4)spring test依赖 -->
-
<dependency>
-
<groupId>org.springframework</groupId>
-
<artifactId>spring-test</artifactId>
-
<version>4.1.3.RELEASE</version>
-
</dependency>
-
<!-- https://mvnrepository.com/artifact/junit/junit -->
-
<dependency>
-
<groupId>junit</groupId>
-
<artifactId>junit</artifactId>
-
<version>4.11</version>
-
</dependency>

下面我给出一个测试示例:
-
//整合junit和spring,让junit在启动时候加载springIOC容器
-
@RunWith(SpringJUnit4ClassRunner.class)
-
//告诉junit spring的配置文件,需要用到的配置文件,如果是dao的话可以不用spring-service.xml
-
@ContextConfiguration({ "classpath:spring-dao.xml",
-
"classpath:spring-service.xml" })
-
public class SeckillServiceTest {
-
@Autowired
-
private SeckillService seckillService;
-
private Logger logger = LoggerFactory.getLogger(this.getClass());
-
@Test
-
public void testGetSeckillList() {
-
List<Seckill> seckills = seckillService.getSeckillList();
-
logger.info("list={}", seckills);
-
}
-
}
