java - Spring - Maven |贾斯珀依赖

标签 java spring maven jasper-reports pom.xml

我正在尝试将 jasper 依赖项添加到我的 spring 项目中，但出现以下错误
我已经尝试过不同版本的 jasper 和 log4j 但我无法让它工作:
我使用的是最新版本的spring和oracle weblogic 11g。
仅当我添加 jasper 依赖项时才会发生这种情况。
有人遇到同样的问题吗？

我检查了 pom.xml 中的依赖层次结构，发现了一些奇怪的东西，我将放在下面 这可能是问题所在？但这很奇怪，因为它只在我每次添加 jasper 的依赖项时发生。我开发了其他东西并且从未发生过冲突。

最佳答案

第二个答案

第一个错误表明正在使用不兼容的 XML 解析器实现。最有可能的是，Weblogic 提供了它自己的实现，这与您的依赖项之一引入的 XML 解析器实现相冲突。您需要弄清楚是什么引入了 XML 解析器，然后排除该解析器。许多 IDE(例如使用 m2eclipse 时的 Eclipse)可以提供 POM 的可视化图表来帮助找出依赖关系。或者，我认为您可以使用'mvn dependency:tree '.

第二个错误似乎表明org.apache.log4j.LogManager不在类路径上。假设您正确构建了 war (或爆炸 war )并且所有 Maven 生成的依赖项 jar 都位于/WEB-INF/lib 文件夹中，那么我最好的猜测是有两个 log4j 实现正在运行，并且它们是冲突的。 (也许 weblogic 包含一个 log4j 实现，并且默认情况下可将其提供给 web 应用程序。)要测试这一点，您可以尝试将 log4j 依赖范围设置为“provided”。如果 log4j 仍然存在问题，您可以考虑使用 slf4j 自己的日志记录实现 ( logback )。即

  <dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <scope>runtime</scope>
    <version>1.0.0</version>
  </dependency>

第一个答案(也许有用，但没有解决主要问题。)

尝试从 jasper 中排除 commons-logging。

此外，我注意到您直接使用 Jackson。贾斯帕也对 jackson 有依赖。就我而言，我还需要将 Jackson 从 Jasper 中排除，以便我可以引用更新的版本。

  <dependency>
    <groupId>net.sf.jasperreports</groupId>
    <artifactId>jasperreports</artifactId>
    <version>4.5.0</version>
    <exclusions>
      <exclusion>
        <groupId>commons-logging</groupId>
        <artifactId>commons-logging</artifactId>
      </exclusion>
      <exclusion>
        <artifactId>jackson-mapper-lgpl</artifactId>
        <groupId>org.codehaus.jackson</groupId>
      </exclusion>
      <exclusion>
        <artifactId>jackson-core-lgpl</artifactId>
        <groupId>org.codehaus.jackson</groupId>
      </exclusion>        
    </exclusions>
  </dependency>

我发现您确实从许多其他依赖项中正确删除了公共(public)日志记录。如果您检查最终的传递依赖项，您不应该看到 commons-logging.jar。

(另外，我尝试稍微改进一下 XML 的格式。以前很难阅读。仍然不是那么容易阅读，但更好了。)
