通过Gitlab Open api代码来操作代码的合并及关闭，项目的模板生成........

方式一：

 使用java-gitlab-api(推荐)
接口文档Java Gitlab API Documentation

        
            org.gitlab
            java-gitlab-api
            4.1.1
       
 

 方式二：

gitlab4j-api
文档地址https://github.com/gitlab4j/gitlab4j-api#tagsapi

         
            org.gitlab4j
            gitlab4j-api
            4.15.7
       
 

编写调用局部代码：

@PostConstruct
public void init(){gitlabAPI = GitlabAPI.connect(gitLabConfigProperties.getHostUrl(),gitLabConfigProperties.getAdminAccessToken());
}

【例】分支比较，传递时需要对调分支

 ....

GitlabCommitComparison compare = gitlabAPI.compareCommits(mergeApplyDTO.getGitlabProjectId(),mergeApplyDTO.getTargetBranch(),mergeApplyDTO.getSourceBranch());
Assert.isTrue(!CollectionUtils.isEmpty(compare.getDiffs()), "分支合并申请,分支没有变化!");

...
