Jira插件开发中的附件上传

介绍一下附件上传的操作，内容是这样，通过一个自定义Action，上传附件同时根据在Action的动作里面创建一个Issue，然后附件挂到该Issue上去

test.vm

<form enctype="multipart/form-data" action="$requestContext.baseUrl/secure/TestAction.jspa" method="post">
    <input type="file" name="file" >
    <input type="submit">
</form>

TestAction.java

@Override
    protected String doExecute() throws Exception {
        MultiPartRequestWrapper wrapper = (MultiPartRequestWrapper) ServletActionContext.getRequest();
        File f = wrapper.getFile("file");   //表单中的name

        IssueInputParameters issueInputParameters = new IssueInputParametersImpl();
        issueInputParameters.setProjectId(10000l).setIssueTypeId("1").setSummary("测试附件").setReporterId("admin").setAssigneeId("admin");
        IssueService.CreateValidationResult createValidationResult = issueService.validateCreate(this.getLoggedInUser(), issueInputParameters);
        if (createValidationResult.isValid()) {
            IssueService.IssueResult createResult = issueService.create(getLoggedInUser(), createValidationResult);
            MutableIssue mutableIssue = createResult.getIssue();
            attachmentManager.createAttachment(f, wrapper.getFilesystemName("file"), wrapper.getContentType("file"), getLoggedInUser(), mutableIssue);
        }
        
        return SUCCESS;
    }

对于文件上传的表单需要这样处理

MultiPartRequestWrapper wrapper = (MultiPartRequestWrapper) ServletActionContext.getRequest();

 得到wrapper对象后，

//得到要上传的文件对象
wrapper.getFile("file");
//取得文件名称
wrapper.getFilesystemName("file");
//取得文件类型
wrapper.getContentType("file");

 创建好Issue之后使用AttachmentManager中的createAttachment方法来将附件和Issue关联

ChangeItemBean createAttachment(File file, String filename, String contentType, User author, Issue issue) throws AttachmentException;
