java - Maven 项目中关于添加 jasper-report 依赖项的构建问题

Question

在我的基于 Spring 的 Camel maven 项目中为 Jasper 报告添加以下依赖项时，我在项目构建时遇到了问题。

贾斯珀依赖项:

<dependency>
        <groupId>net.sf.jasperreports</groupId>
        <artifactId>jasperreports</artifactId>
        <version>6.0.4</version>
   </dependency> 

下面是异常的堆栈跟踪:

我认为 jasper 报告的支持 jackson 依赖项与以前的依赖项发生冲突。

下面是 jasper 报告的 pom.xml 的依赖关系层次结构。

但是，如果我删除 jasper 报告的依赖项，那么它就可以正常工作。

我无法准确地解决这个问题。

你的问题有误，已更改答案

您的方法所在的类是 jackson.core 2.4.3 的一部分。如果您明确包含该内容，它应该可以解决您的问题。

添加以下依赖项:

<dependency> 
    <groupId>com.fasterxml.jackson.core</groupId> 
    <artifactId>jackson-core</artifactId> 
    <version>2.4.3</version> 
</dependency>
<dependency> 
    <groupId>com.fasterxml.jackson.core</groupId> 
    <artifactId>jackson-annotations</artifactId> 
    <version>2.4.3</version> 
</dependency>
