提示一下错误信息为提示响应使用的注解类未被注入

看我使用案例
package com.qinghuainvest.cmndd; import java.util.List; import javax.annotation.Resource; import org.junit.Test; import com.qinghuainvest.TestBaseCtrl; import com.qinghuainvest.base.service.YptDictionaryFactoryDB; import com.qinghuainvest.cmndd.dict.model.Dictionary; public class DictServiceTest extends TestBaseCtrl { @Resource private YptDictionaryFactoryDB yptDictionaryFactoryDB; @Test public void test() { Dictionary dict = yptDictionaryFactoryDB.getDictionary("0001"); System.out.println(dict); } @Test @SuppressWarnings("rawtypes") public void testFind(){ List list = super.ybEnterpriseBasicInfoService.findList(); System.out.println(list.size()); } }
我以为如下类应该是已经被注入了
package com.qinghuainvest.base.service; import org.springframework.stereotype.Component; import com.qinghuainvest.cmndd.dict.service.impl.DictionaryFactoryDB; import com.qinghuainvest.cmndd.util.cfg.ConfigFile; @Component("yptDictionaryFactoryDB") public class YptDictionaryFactoryDB extends DictionaryFactoryDB { private static final long serialVersionUID = 1L; public YptDictionaryFactoryDB() { ..... } }
但是时发现被未被注入,提示上面错误。
究其原因在于:spring的配置注解文件类库中并未标识指定文件下的类导致未被识别
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:task="http://www.springframework.org/schema/task" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd"> <context:component-scan base-package="com.qinghuainvest.enterprise.*" /> <context:component-scan base-package="com.qinghuainvest.institution.*" /> <context:component-scan base-package="com.qinghuainvest.report.*" /> <context:component-scan base-package="com.qinghuainvest.securities.*" /> <context:component-scan base-package="com.qinghuainvest.test.*" /> <context:component-scan base-package="com.qinghuainvest.cmndd.*" /> <task:annotation-driven /> </beans>
所以最后将修改的地方为(下面红色一行,想需要识别的类库引入)
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:task="http://www.springframework.org/schema/task" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd"> <context:component-scan base-package="com.qinghuainvest.enterprise.*" /> <context:component-scan base-package="com.qinghuainvest.institution.*" /> <context:component-scan base-package="com.qinghuainvest.report.*" /> <context:component-scan base-package="com.qinghuainvest.securities.*" /> <context:component-scan base-package="com.qinghuainvest.test.*" /> <context:component-scan base-package="com.qinghuainvest.base.*" /> <context:component-scan base-package="com.qinghuainvest.cmndd.*" /> <task:annotation-driven /> </beans>
执行结果:成功
