我正在尝试在模块上运行Groovy和AspectJ，但是当我添加AspectJ时，类似乎返回的值与我预期的不同：
junit.framework.ComparisonFailure: null expected:<2011-04-03> but was:<null>
testGetUnixDayFromDate(com.baselogic.chapter05.utils.DateUtilitiesTest) Time elapsed: 0.016 sec <<< FAILURE!
junit.framework.AssertionFailedError: expected:<0> but was:<15037>
testGetDateDifferenceInDays(com.baselogic.chapter05.utils.DateUtilitiesTest) Time elapsed: 0 sec <<< FAILURE!
junit.framework.AssertionFailedError: expected:<0> but was:<7>
这不是我的预期，当我关闭AspectJ时，这一切都运行良好。

这是我的AspectJ插件似乎导致了这个问题：

但是当我启用 aspectj-maven-plugin 时，一切都开始失败：

[ERROR] There are test failures.
Please refer to C:\usr\SYNCH\PACKT\3166\Chapters_Code\ch05\target\surefire-reports for the individual test results.
这是Groovy测试：
package com.baselogic.chapter05.utils
import groovy.util.GroovyTestCase
import java.util.Calendar
import java.text.SimpleDateFormat
class DateUtilitiesTest extends GroovyTestCase {
protected void setUp() {
super.setUp()
}
protected void tearDown() {
super.tearDown()
}
public void testGetYesterdayDate() {
Calendar calendar = Calendar.getInstance()
calendar.add(Calendar.DATE, -1)
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd")
String expected = format.format(calendar.getTime());
String result = DateUtilities.getYesterdayDate()
println(result)
assertEquals(expected, result)
}
void testGetUnixDayFromDate() {
java.text.SimpleDateFormat formatter = new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
java.util.Date date = (java.util.Date) formatter.parse("2011-03-03 23:59:59");
assertEquals(DateUtilities.getUnixDayFromDate(date), 15037);
}
void testGetDateDifferenceInDays() {
java.text.SimpleDateFormat formatter = new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
java.util.Date date1 = (java.util.Date) formatter.parse("2011-03-03 23:59:59");
java.util.Date date2 = (java.util.Date) formatter.parse("2011-03-10 23:59:59");
assertEquals(DateUtilities.getDateDifferenceInDays(date1, date2), 7);
}
}
然后我也创建了一个Java单元测试用例：
package com.baselogic.chapter05.utils;
import org.junit.Test;
import static org.junit.Assert.assertEquals;
import java.text.SimpleDateFormat;
import java.util.Calendar;
public class DateUtilitiesJavaTest {
@Test
public void testGetYesterdayDate() {
Calendar calendar = Calendar.getInstance();
calendar.add(Calendar.DATE, -1);
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
String expected = format.format(calendar.getTime());
String result = DateUtilities.getYesterdayDate();
// Aspect DontWriteToTheConsole will complain:
// System.out.println(result);
assertEquals(expected, result);
}
@Test
public void testGetYesterdayDateScala() {
Calendar calendar = Calendar.getInstance();
calendar.add(Calendar.DATE, -1);
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
String expected = format.format(calendar.getTime());
String result = ScalaDateUtilities.getYesterdayDate();
assertEquals(expected, result);
}
}
任何人都可以帮助我理解为什么 aspectj-maven-plugin 似乎导致我的最终字节码出现编译错误？
答案 0 :(得分：2)
我对GMaven的经验很差。一旦我切换到Gradle，很多“古怪”就消失了。这听起来像你不想浪费时间用GMaven那样奇怪。
答案 1 :(得分：0)
我认为切换到Gradle不是一种解决方案，而是一种昂贵的解决方法，特别是对于大型项目。所以我不同意 Mike Wazowski 。也许你应该修复你的Maven设置。你可以做几件事：
首先，AspectJ Maven 1.3.1从2011年开始使用，并使用了一个非常古老的AspectJ版本（1.6.10）。为什么不升级到默认情况下使用AsepctJ 1.8.2的AspectJ Maven 1.7？您甚至可以将其升级到AspectJ 1.8.6，这是包含更多错误修正的最新版本？
您还可以考虑从GMaven切换到GMavenPlus，因为前者不再是AFAIK，而后者是。
顺便说一句，您也可以从Java 6切换到8或至少7，因为不再维护Java 6.
我的AspectJ Maven设置通常看起来像这样（我在这里省略了GMaven设置）：

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<java.source-target.version>1.8</java.source-target.version>
