我正在尝试使用XWiki LogRule来捕获记录器输出。没有捕获输出。目前尚不清楚我做错了什么。我已经阅读了相关的代码和文档，觉得我已经做了彻底的搜索 - 一切都无济于事。我选择了这个解决方案，因为它似乎是最优雅的问题。
我正在尝试确定问题的范围以及从Mockito 1.8.5迁移到1.9.5所产生的问题的可能解决方案。我们曾经能够插入到最终字段中，并且不再能够 - 我理解为什么 - 使用@InjectMocks。
一种解决方案是删除最终修饰符。另一种方法是创建重载的构造函数并手动注入。第一个是难吃的。第二个是丑陋的，因为它引入了仅用于测试的代码，并且在模拟记录器时，记录器是唯一的最终字段。因此，在记录器是唯一的问题的情况下，我认为使用xwiki-commons-test-simple-5.4.1.jar中提供的XWiki LogRule是有意义的。
以下是测试类中规则的实现：
@Rule
public LogRule logRule = new LogRule()
{
{
record(LogLevel.INFO);
recordLoggingForType(EmployerNameCacheLoadServiceImpl.class);
}
};
以下是测试中规则的执行情况：
@Test
public void testLoadCache_FormatAndLogData()
{
String key = "key";
String incorrectKey = key + " \n random malicious text";
String incorrectStorageId = STORAGE_ID + " \n random malicious text";
String incorrectUserGuid = USER_GUID + " \n random malicious text";
when(serviceUser.getOwningFirm()).thenReturn(incorrectStorageId);
when(serviceUser.getUserGuid()).thenReturn(incorrectUserGuid);
when(employerNameLoadSummaryCache.get(anyString())).thenReturn(null);
when(searchableEmployerNameFactory.createSearchableEmployerNames(eq(serviceUser), anyString()))
.thenReturn(new HashMap<String, SearchableEmployerName>());
when(stringSecurityFormatter.formatString(incorrectKey)).thenReturn(key);
when(stringSecurityFormatter.formatString(incorrectStorageId)).thenReturn(STORAGE_ID);
when(stringSecurityFormatter.formatString(incorrectUserGuid)).thenReturn(USER_GUID);
employerNameCacheLoadService.loadCache(serviceUser, incorrectKey);
verify(stringSecurityFormatter).formatString(incorrectKey);
verify(stringSecurityFormatter).formatString(incorrectStorageId);
verify(stringSecurityFormatter).formatString(incorrectUserGuid);
String expectedLogEntry =
String.format("Cache load(%s) of firm (%s) for batch (%s) by user(%s). A total of %d entries.",
key,
STORAGE_ID,
anyString(),
USER_GUID,
0);
// verify（logger）.info（expectedLogEntry）; System.out.println（“this.logRule.size（）is”+ this.logRule.size（））; System.out.println（“this.logRule.toString（）is”+ this.logRule.toString（））; assertThat（this.logRule.size（），是（1））; assertThat（this.logRule.getMessage（0），containsString（expectedLogEntry））; assertThat（this.logRule.toString（），containsString（expectedLogEntry））; }
你可以看到我尝试了很多变化。对logRule.size（）的调用返回0，它应该始终记录一个INFO条目。
以下是目标类中记录器的定义：
private final Logger logger = Logger.getLogger(EmployerNameCacheLoadServiceImpl.class);
以下是测试中的方法：
@Override
public String loadCache(final serviceUser user, final String key)
{
NamesLoadSummary namesLoadSummary = employerNameLoadSummaryCache.get(key);
String batchId = null;
Date now = new Date();
if (namesLoadSummary == null || now.after(namesLoadSummary.getExpiresDateTime()))
{
batchId = UUID.randomUUID().toString().replace("-", "");
final Map<String, SearchableEmployerName> mapOfSearchableNames =
searchableEmployerNameFactory.createSearchableEmployerNames(user, batchId);
employerNamesCache.putAll(mapOfSearchableNames);
namesLoadSummary = new NamesLoadSummary();
namesLoadSummary.setBatchId(batchId);
namesLoadSummary.setStorageId(key);
namesLoadSummary.setExpiresDateTime(employerNameCacheExpiryCalculator.calculateExpiryDate());
employerNameLoadSummaryCache.put(key, namesLoadSummary);
logger.info(String.format("Cache load(%s) of firm (%s) for batch (%s) by user(%s). A total of %d entries.",
stringSecurityFormatter.formatString(key),
stringSecurityFormatter.formatString(user.getOwningFirm()),
batchId,
stringSecurityFormatter.formatString(user.getUserGuid()),
mapOfSearchableNames.size()));
}
else
{
batchId = namesLoadSummary.getBatchId();
}
return batchId;
}
这是控制台输出：

如您所见，它确实记录了。您还可以看到有一些slf4j绑定警告。这似乎不应该是问题，但一旦发布就会进一步研究这个角度。
我正在寻找是解决此问题的建议，以便LogRule捕获已记录的输出。
我意识到 - 在我最初发布之后 - 我没有将logback-test.xml添加到我的项目中。这样做，测试仍然像以前一样失败，但控制台是不同的。上面的控制台日志现在反映了这种变化。
这是我的log4j.xml：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd" >
<log4j:configuration>
<appender name="ConsoleAppender" class="org.apache.log4j.ConsoleAppender">
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d %-5p [%t] %c{1}: %m%n"/>
</layout>
</appender>
<logger name="com.xxx.yyy.zzz">
<level value="INFO" />
</logger>
<logger name="org.hibernate">
<level value="ERROR" />
</logger>
<root>
<level value="WARN"/>
<appender-ref ref="ConsoleAppender"/>
</root>
</log4j:configuration>
这里是前面提到的logback-test.xml：
