如何让 Apache POI 5.2.0 在 Jira 9.11.2 中工作

Question

如何让 Apache POI 5.2.0 在 Jira 9.11.2 中工作？

pom.xml：

    <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-api</artifactId>
        <version>2.17.1</version>

以下是错误消息：

第 494 行如下：

wb.write(out);

pw.print( out );

出去就在这里

    PrintWriter pw = new PrintWriter( new OutputStreamWriter( resp.getOutputStream() ) );
    OutputStream out = resp.getOutputStream();

我从 ChatGPT 获得信息，这个问题必须像下面这样修复，但我不知道在 pom.xml 中写更多内容：

<dependency>
    <groupId>com.atlassian.jira</groupId>
    <artifactId>jira-api</artifactId>
    <version>${jira.version}</version>
</dependency>

以及如何在实现此功能后获得构建成功以及还需要什么：

<plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>3.2.4</version>
            <configuration>
                <relocations>
                    <relocation>
                        <pattern>org.apache.poi</pattern>
                        <shadedPattern>fi.i4ware.plugin.timesheet.tfj.org.apache.poi</shadedPattern>
                    </relocation>
                    <!-- Add relocations for other conflicting packages -->
                </relocations>
            </configuration>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

不是

添加一行时

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

然后我收到错误：

 2023-11-24 15:00:14,914+0000 http-nio-8080-exec-6 url: /internal-error ERROR      [c.a.j.web.servlet.InternalServerErrorServlet] {errorId=ad959c71-6ae3-4c80-8929-13c11e7856d7, interpretedMsg=, cause=java.lang.ClassCastException: class org.apache.xerces.jaxp.DocumentBuilderFactoryImpl cannot be cast to class javax.xml.parsers.DocumentBuilderFactory (org.apache.xerces.jaxp.DocumentBuilderFactoryImpl is in unnamed module of loader org.apache.catalina.loader.ParallelWebappClassLoader @1643d68f; javax.xml.parsers.DocumentBuilderFactory is in unnamed module of loader org.apache.felix.framework.BundleWiringImpl$BundleClassLoader @70819ac9), stacktrace=java.lang.ClassCastException: class org.apache.xerces.jaxp.DocumentBuilderFactoryImpl cannot be cast to class javax.xml.parsers.DocumentBuilderFactory (org.apache.xerces.jaxp.DocumentBuilderFactoryImpl is in unnamed module of loader org.apache.catalina.loader.ParallelWebappClassLoader @1643d68f; javax.xml.parsers.DocumentBuilderFactory is in unnamed module of loader org.apache.felix.framework.BundleWiringImpl$BundleClassLoader @70819ac9)

Answer 1

这看起来像是库之间的依赖冲突。 修复步骤：

1. 安装maven maven-dependency-plugin
2. 运行命令 mvn dependency:tree -Dverbose
3. 找到冲突。
4. 排除冲突的库，这是示例

<dependency>
        <groupId>com.baeldung</groupId>
        <artifactId>project-a</artifactId>
        <version>0.0.1-SNAPSHOT</version>
        <exclusions>
            <exclusion>
                <groupId>com.google.guava</groupId>
                <artifactId>guava</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
