在JIRA中，可以使用JIRA API来获取看板的相关信息，包括用户对看板的观点。以下是一个使用JIRA Java API的示例代码，用于获取不同用户对同一个看板的观点：

import com.atlassian.jira.rest.client.api.JiraRestClient;
import com.atlassian.jira.rest.client.api.domain.Board;
import com.atlassian.jira.rest.client.api.domain.BoardConfiguration;
import com.atlassian.jira.rest.client.internal.async.AsynchronousJiraRestClientFactory;
import com.atlassian.util.concurrent.Promise;
import io.atlassian.util.concurrent.Promises;

import javax.ws.rs.core.UriBuilder;
import java.net.URI;
import java.util.ArrayList;
import java.util.List;
import java.util.concurrent.ExecutionException;

public class JiraBoardViewpoints {

    public static void main(String[] args) throws ExecutionException, InterruptedException {
        String jiraUrl = "http://your-jira-url";
        String username = "your-username";
        String password = "your-password";

        // Create JIRA REST client
        URI jiraServerUri = UriBuilder.fromUri(jiraUrl).build();
        JiraRestClient restClient = new AsynchronousJiraRestClientFactory()
                .createWithBasicHttpAuthentication(jiraServerUri, username, password);

        // Board ID of the desired board
        int boardId = 123;

        // Get board configuration
        Promise boardPromise = restClient.getBoardClient().getBoard(boardId);
        Board board = boardPromise.get();

        // Get board configuration
        Promise boardConfigPromise = board.getConfiguration();
        BoardConfiguration boardConfig = boardConfigPromise.get();

        // Get all users' viewpoints
        List userViewpoints = new ArrayList<>();
        for (BoardConfiguration.Column column : boardConfig.getColumns()) {
            for (BoardConfiguration.Subcolumn subColumn : column.getSubcolumns()) {
                for (String user : subColumn.getView()) {
                    if (!userViewpoints.contains(user)) {
                        userViewpoints.add(user);
                    }
                }
            }
        }

        // Print user viewpoints
        System.out.println("Different users' viewpoints for board " + board.getName() + ":");
        for (String user : userViewpoints) {
            System.out.println(user);
        }

        // Close JIRA REST client
        Promises.toCallable(() -> restClient.close()).call();
    }
}

请确保将以下依赖项添加到您的项目中的pom.xml文件：

    
        com.atlassian.jira
        jira-rest-java-client-api
        5.0.0-m31
    
    
        com.atlassian.jira
        jira-rest-java-client-core
        5.0.0-m31
    
    
        com.atlassian.jira
        jira-rest-java-client-plugin
        5.0.0-m31
    
    
        io.atlassian.util.concurrent
        atlassian-util-concurrent
        2.4.0
    

请替换your-jira-url，your-username和your-password为您的JIRA实例的URL，用户名和密码。将boardId更改为您要获取观点的看板的ID。

运行代码后，它将打印出不同用户的观点列表。
