我有两个相同类型的bean，我使用父子作业（一个覆盖另一个）。在尝试自动配置它们时，我知道我需要指定一个@Qualifier语句，以便Spring可以将正确的bean注入我的Test案例中。我这样做了：
@Autowired @Qualifier（＆＃34; LoadAcceptanceTestDataJob＆＃34） private JobLauncherTestUtils jobLauncherUtils;
我的工作定义如下：
<import resource="load-bms-job.xml"/>
<batch:job id="LoadAcceptanceTestDataJob" parent="LoadBMSJob">
<batch:step id="AcceptanceDeleteAcctMap" parent="deleteAcctMap" next="AcceptanceDeleteCountrySkippingExclusion" />
<batch:step id="AcceptanceDeleteCountrySkippingExclusion" parent="deleteCountrySkippingExclusion" next="AcceptanceDeleteBlueReportOut" />
<batch:step id="AcceptanceDeleteBlueReportOut" parent="deleteBlueReportOut" next="AcceptanceDeleteShadowBMSContract" />
<batch:step id="AcceptanceDeleteShadowBMSContract" parent="deleteShadowBMSContract" next="AcceptanceCountrySkippingExclusionStep" />
<batch:step id="AcceptanceCountrySkippingExclusionStep" parent="countrySkippingExclusionStep" next="AcceptanceMappingFileLoadStep" />
<batch:step id="AcceptanceMappingFileLoadStep" parent="mappingFileLoadStep" next="Override-ExtractAndLoad-BMS-Data-Step" />
<batch:step id="Override-ExtractAndLoad-BMS-Data-Step" parent="ExtractAndLoad-BMS-Data-Step">
<batch:tasklet>
<batch:chunk reader="BMSDataItemReaderCSV" />
</batch:tasklet>
</batch:step>
</batch:job>
这是我的stacktrace：
