我遇到了一个问题,即我试图通过 spring 配置连接的 bean 不起作用?在我的测试用例中进行检查期间,bean 访问器显示为 null(但我确实在日志中观察到 setter 实际上将其设置为有效值。真的可以使用一些帮助......

这是代码:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="/test-context.xml")
public abstract class HistoryCompress extends TestBase {

    private CompressionArchive compressArchive;
    public void setCompressionArchive(CompressionArchive value)
    {
        this.logInfo("setting compression archive: %s, name: %s",value,value.getcompressionFormat());
        this.compressArchive=value;
    }

    protected CompressionArchive getCompressionArchive()
    {
        return this.compressArchive;
    }

    @Test
    public void getArchiveTypeName()
    {
        logInfo("test");
        this.assertNotNull(this.getCompressionArchive(),"compression archive is null");     
        this.assertNotNull(this.getCompressionArchive().getcompressionFormat(), "format name is null");
        logInfo("format: %s",this.getCompressionArchive().getcompressionFormat());
    }

}

public class HistoryZipCompress extends HistoryCompress 
{
    public HistoryZipCompress()
    {
        this.logInfo("-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-");
        this.logInfo("-=-=-=--=- C'Tor HistoryZipCompress");
        this.logInfo("-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-");
    }

}

public interface CompressionArchive {
    public String getcompressionFormat();
    public Map<String,String> getArchiveHashes(InputStream stream,String password) throws Exception;
}
public class CompressionArchiveZip extends IntegrationBase implements CompressionArchive
{
   /* implementation methods*/
}


然后我试图用下面的配置来连接它

<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:jaxws="http://cxf.apache.org/jaxws"
    xmlns:util="http://www.springframework.org/schema/util" 
    default-autowire="byName"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
        http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">

    <context:annotation-config />       
    <bean class="gdg.scc.integration.testcases.file.history.HistoryZipCompress">
        <property name="compressionArchive"  ref="zipArchive" />
    </bean>     
    <bean id="zipArchive" class="gdg.scc.integration.global.helpers.compression.impl.CompressionArchiveZip" />
</beans>

当我运行它时,我观察到 HistoryZipCompress 被实例化了 3 次不同的时间,这是在 HistoryZipCompress 上运行 getArchiveTypeName 的结果:

使用@Autowired 注释该字段:

@Autowired
private CompressionArchive compressArchive;

在 xml 配置中抛弃 HistoryZipCompress - 它在那里做什么?您不需要创建测试类的另一个实例,运行程序会为您执行此操作。

您需要将测试对象注入 CompressionArchive 实例。Spring runner 管理您的测试对象(HistoryCompress),但不知道您想要注入 CompressionArchive 实例。
