Question

我想在AngularJS应用程序中单击一个按钮时下载文件，该应用程序在具有Java Spring后端的Tomcat上运行，但没有任何反应。后端中的方法被调用，似乎一切正常。...但是我的浏览器没有下载任何东西。

我想念什么？

这是AngularJS代码，记录了Export-Response:[object Object]：

exportProjects() {
    let filteredProjectIds = [];
    for (let i in this.filteredProjects) {
        for (let x = 0, l = this.filteredProjects[i].length; x < l; x++) {
            if (!this.isOldProjectsBundle(this.filteredProjects[i][x])) {
                filteredProjectIds.push(this.filteredProjects[i][x].id);
            }
        }
    }
    this.$http.get('/profiles/projectWordExport?filteredProjects=' + filteredProjectIds.join(",")).then(response => {
        console.log("Export-Response:" + response);
        return response;
    });
}

这是被调用的Java代码（它实际上已经被调用，已经调试过，没有发生错误）：

@RequestMapping(value = "/projectWordExport", method = RequestMethod.GET)
    public void getProjectsWord(HttpServletRequest request, HttpServletResponse response, @RequestParam String filteredProjects) throws Exception {
        //Load project objects from input string or load all projects if input empty
        List<Project> projects = new java.util.ArrayList<>();
        if (filteredProjects.isEmpty()) {
            projects = projectRepository.findAll();
        } else {
            String[] pIds = filteredProjects.split(",");
            for (String pId : pIds) {
                projects.add(projectRepository.findById(Long.parseLong(pId)));
            }
        }

        response.setContentType("application/vnd.openxmlformats-officedocument.wordprocessingml.document");
        response.setHeader("Content-disposition", "attachment;filename=Projektexport.docx");

        try {
            SaveToZipFile saver = new SaveToZipFile(printer.printProjects(this.prepareProjectExport(projects)));
            saver.save(response.getOutputStream());
            response.flushBuffer();
        } catch (NullPointerException e) {
            response.setStatus(500);
            response.sendError(500, "Fehler beim exportieren des Tests aufgetreten");
        }
    }

将其放在@RequestMapping注释中

produces = MediaType.APPLICATION_OCTET_STREAM_VALUE
