无法使JUnit与我的@Autowired存储库和MongoTemplate一起使用

Question

I'm having some trouble figuring out how to write a JUnit test on my Repository, which I want to be autowired within my application. I have the repository + test class + XML + error message below. Basically I think the application XML config is incomplete but I'm stuck at the moment on what I need to add... anyone have any idea? Thanks.

package org.jswiki.persistence;

@Repository
public class JSWikiRepository {

    @Autowired
    MongoTemplate mongoTemplate;

    public JSWikiRepository() {

    }

    public List<JSWikiItem> getAll() {
        return mongoTemplate.findAll(JSWikiItem.class);
    }
}

This is my test class:

package org.jswiki;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"*/conf-mongodb.xml"})
public class MongoTest {

    @Autowired
    private JSWikiRepository jsRep;

    @Test
    public void canCreateNewRecord() {

        List<JSWikiItem> listWiki = jsRep.getAll();

        //for(JSWikiItem i : listWiki) {
        //  System.out.println(i.getTitle());
        //}

        assertEquals(1, 1);
    }
}

This is my XML

   <!-- Activate annotation configured components -->
   <context:annotation-config/>

   <!-- Scan components for annotations within the configured package -->
   <context:component-scan base-package="org.jswiki.controller" />
   <context:component-scan base-package="org.jswiki.domain" />
   <context:component-scan base-package="org.jswiki.persistencer" />

   <!-- Define the MongoTemplate which handles connectivity with MongoDB -->
   <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
     <constructor-arg name="mongo" ref="mongo"/>
     <constructor-arg name="databaseName" value="jswiki"/>
   </bean>

   <!-- Factory bean that creates the Mongo instance -->
   <bean id="mongo" class="org.springframework.data.mongodb.core.MongoFactoryBean">
     <property name="host" value="178.62.218.109"/>
   </bean>

   <!-- Use this post processor to translate any MongoExceptions thrown in @Repository annotated classes -->
   <bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor"/>

Answer 1

你必须在“基本包=“org.jswiki。persistencer”拼写错误，而JSWikiRepository的包是org.jswiki.persistence。
