flowable-ui-idm,task,modeler 三個模塊可以正常顯示中文，但是flowable-ui-admin中文不能正常顯示（flowable6.1.2以下版本包括該版本），比如我們定義了流程之后，顯示查詢之后，如下圖所示：

下面，我們看一下這個bug出現(xiàn)的原因。首先我們看一下上傳文檔對應的實現(xiàn)，該服務功能位于DeploymentCollectionResource類中的uploadDeployment方法中，實例代碼如下：

public DeploymentResponse uploadDeployment(@ApiParam(name = "deploymentKey") @RequestParam(value = "deploymentKey", required = false) String deploymentKey,

@ApiParam(name = "deploymentName") @RequestParam(value = "deploymentName", required = false) String deploymentName,

@ApiParam(name = "tenantId") @RequestParam(value = "tenantId", required = false) String tenantId,

HttpServletRequest request, HttpServletResponse response) {

......

if (StringUtils.isEmpty(deploymentName)) {

}

看到上述的代碼StringUtils.isEmpty(deploymentName)就明白了，原來這個地方并沒有進行編碼工作，中文當然要亂碼了，正確的寫法，應該是對所有的參數(shù)進行解碼，類似下面的代碼：

URLDecoder.decode(string, "UTF-8")

如果這個問題，讓我們自己解決可能有點麻煩，所以直接反饋給flowable官方了，目前官方已經(jīng)修復了該bug。如下所示：
