Question

我有一个project A，pom.xml对slf4j具有以下依赖性

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.5.10</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
        <version>1.5.10</version>
    </dependency>

现在我有project B的{{1}}依赖于pom.xml

slf4j

现在我需要集成两个项目，但是当它们有不同的版本时，它们不能很好地协同工作。所以这就是我尝试过的方法1 - 在</dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.6.4</version> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.0.3</version> </dependency> 中升级slf4j 将project A更改为

后

pom.xml

我开始看到构建错误说

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.6.4</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
        <version>1.6.4</version>
    </dependency>

并且测试似乎失败了

SLF4J: The requested version 1.5.10 by your slf4j binding is not compatible with [1.6]
SLF4J: See http://www.slf4j.org/codes.html#version_mismatch for further details.

方法2 - 在java.lang.IllegalStateException: Failed to load ApplicationContext at org.springframework.test.context.TestContext.getApplicationContext(TestContext.java:308) at org.springframework.test.context.support.DependencyInjectionTestExecutionListener.injectDependencies(DependencyInjectionTestExecutionListener.java:109) at org.springframework.test.context.support.DependencyInjectionTestExecutionListener.prepareTestInstance(DependencyInjectionTestExecutionListener.java:75) at org.springframework.test.context.TestContextManager.prepareTestInstance(TestContextManager.java:321) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.createTest(SpringJUnit4ClassRunner.java:220) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner$1.runReflectiveCall(SpringJUnit4ClassRunner.java:301) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.methodBlock(SpringJUnit4ClassRunner.java:303) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:240) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:46) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:180) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:41) at org.junit.runners.ParentRunner$1.evaluate(ParentRunner.java:173) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.springframework.test.context.junit4.statements.RunBeforeTestClassCallbacks.evaluate(RunBeforeTestClassCallbacks.java:61) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:31) at org.springframework.test.context.junit4.statements.RunAfterTestClassCallbacks.evaluate(RunAfterTestClassCallbacks.java:70) at org.junit.runners.ParentRunner.run(ParentRunner.java:220) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.run(SpringJUnit4ClassRunner.java:180) at org.apache.maven.surefire.junit4.JUnit4TestSet.execute(JUnit4TestSet.java:59) at org.apache.maven.surefire.suite.AbstractDirectoryTestSuite.executeTestSet(AbstractDirectoryTestSuite.java:115) at org.apache.maven.surefire.suite.AbstractDirectoryTestSuite.execute(AbstractDirectoryTestSuite.java:102) at org.apache.maven.surefire.Surefire.run(Surefire.java:180) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.maven.surefire.booter.SurefireBooter.runSuitesInProcess(SurefireBooter.java:350) at org.apache.maven.surefire.booter.SurefireBooter.main(SurefireBooter.java:1021) Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name中降级slf4j

更改project B后如下

pom.xml

我在测试中看到错误

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.5.10</version>
    </dependency>
    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>1.0.3</version>
    </dependency>

解决此问题的最佳方法是什么？

更新依赖树在这里

testPutDocument(com.org.sparrow.business.persist.MongoServiceTest): org.slf4j.helpers.MessageFormatter.arrayFormat(Ljava/lang/String;[Ljava/lang/Object;)Lorg/slf4j/helpers/FormattingTuple;
  testPutDocuments(com.org.sparrow.business.persist.MongoServiceTest): org.slf4j.helpers.MessageFormatter.arrayFormat(Ljava/lang/String;[Ljava/lang/Object;)Lorg/slf4j/helpers/FormattingTuple;
  testGetDocument(com.org.sparrow.business.persist.MongoServiceTest): org.slf4j.helpers.MessageFormatter.arrayFormat(Ljava/lang/String;[Ljava/lang/Object;)Lorg/slf4j/helpers/FormattingTuple;

Answer 1

在您的问题中，您提到您已将项目 A 的pom.xml中的slf4j-api和slf4j-log4j12升级到版本 1.6.4 ，但依赖关系树是您的张贴提及slf4j-api和slf4j-log4j12版本 1.5.0 。只要您确定版本使slf4j-api及其绑定版本匹配，您就可以了。

您的其他依赖项为SLF4J声明的SLF4J版本无关紧要。从客户的角度all versions of slf4j are binary compatible。

Answer 2

作为其他项目中的库包含的Jar项目不应包含除slf4j-api之外的POM中的任何内容。由最终项目（即您的示例中的项目A）决定实施。对于测试项目B，可以包含一个实现，例如slf4j-log4j12和log4j本身，但这些应该在Maven中作为范围test。
