pring对Controller、Service、Dao进行Junit单元测试总结
所有用Junit进行单元测试，都需要下面的配置
|
1
2
3
|
@RunWith
(SpringJUnit4ClassRunner.
class
)
@ContextConfiguration
(locations = {
"classpath:applicationContext.xml"
})
|
applicationContext.xml 是整个项目的Spring的配置文件。包括数据源配置、MVC配置和各种Bean的注册扫描。如果你是多个文件，就用都好隔开写多个，像这样
|
1
|
{
"classpath:applicationContext.xml"
,
"classpath:servlet-context.xml"
}
|
1.Dao层的单元测试。
将*Mapper接口注入进来，直接调用即可。加上@Transactional 事物管理注解以后，单元测试执行完后会撤销对数据库的修改。想看增删改的结果的话，可以把这个注解先注释。

2. Service层的单元测试与Dao层基本一致，把Service注入进来调用就行。

3. Controller层的单元测试
一种是把Controller的Bean注入进来，调里面的方法，这很显然比较扯淡，连Url都没经过，只测了方法。另一种是使用MockMvc模拟通过url的接口调用。MockMvc是SpringMVC提供的Controller测试类，每次进行单元测试时，都是预先执行@Before中的setup方法，初始healthArticleController单元测试环境。
注意：一定要把待测试的Controller实例进行MockMvcBuilders.standaloneSetup(xxxxController).build(); 否则会抛出无法找到@RequestMapping路径的异常：No mapping found for HTTP request with URI [/cms/app/getArticleList] in DispatcherServlet
