我已经按照将 Spring Batch Admin 集成到现有应用程序中的答案集成spring-batch-admin到我的应用程序中。

问题 1

首先，我收到以下相关错误slf4j：

java.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;Ljava/lang/Throwable;)V
at org.apache.commons.logging.impl.SLF4JLocationAwareLog.info(SLF4JLocationAwareLog.java:159)
at org.springframework.web.context.ContextLoader.initWebApplicationContext(ContextLoader.java:273)
at org.springframework.web.context.ContextLoaderListener.contextInitialized(ContextLoaderListener.java:112)
...
...

slf4j我通过排除依赖项克服了这个错误（阅读：错误停止但我不知道它是否是解决它的正确方法） ：

<dependency>
  <groupId>org.springframework.batch</groupId>
  <artifactId>spring-batch-admin-manager</artifactId>
  <version>1.2.2.RELEASE</version>
  <exclusions>
    <exclusion>
      <groupId>org.slf4j</groupId>
      <artifactId>jcl-over-slf4j</artifactId>
    </exclusion>
    <exclusion>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-api</artifactId>
    </exclusion>
    <exclusion>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-log4j12</artifactId>
    </exclusion>
  </exclusions>
</dependency>

问题 2

在上述问题 1 的解决方法之后，出现以下错误：

java.lang.IncompatibleClassChangeError: class org.springframework.core.type.classreading.ClassMetadataReadingVisitor has interface org.springframework.asm.ClassVisitor as super class
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:788)
at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142)
...
...

根据启动Java项目时的Class Conflict：ClassMetadataReadingVisitor有接口org.springframework.asm.ClassVisitor作为超类，这是由于使用了多个spring库版本造成的。

问题

  1. 问题 1 的解决方案是否正确？我可以在依赖项的 POM 中排除一个依赖项并期望事情正常工作（通过使用我的项目正在使用的 slf4j 版本）吗？
  2. 问题2可以用同样的方法解决吗？我的应用程序没有使用 所需的所有依赖项spring-batch-admin，所以我应该排除错误的版本并包含正确的版本吗？
  3. 这似乎是为了让事情正常工作而进行的大量黑客攻击。有没有更好的办法”？

更新

按要求提供主 pom 文件。为简洁起见，一些信息已被删除。我还删除了私人信息：

如果您查看依赖 hirarchie，您会发现 slf4j 来自 spring-batch-integration、ehcache-core 和 spring-batch-admin-resources。换句话说，这意味着您所做的排除无法正常工作。
