我遇到一个问题，我试图通过Spring配置连接的bean不起作用？bean访问器在我的测试用例中的检查期间显示为null（但我确实在日志中观察到setter实际上将其设置为一个有效值。真的需要一些帮助…

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*/
}

    </bean>     
    <bean id="zipArchive" class="gdg.scc.integration.global.helpers.compression.impl.CompressionArchiveZip" />
</beans>

当我运行这个时，我观察到历史ZipCompress被实例化了3次不同的时间，这是在历史ZipCompress上运行getArchiveTypeName的尾部：
