spring-mvc - thymeleaf 模板中的 JSON 序列化对象

Question

thymeleaf 中是否有办法从上下文中输出对象的 json。我可以在 Controller 内完成，但真的不想这样做。

Controller :

@RequestMapping("/{projectId}/edit")
public String editProject(Model model, @PathVariable Long projectId) {
    Project project = projectRepo.findOne(projectId);
    // Below line works, but I want to put the object to the model
    // model.addAttribute("project", new ObjectMapper().writeValueAsString(project));
    model.addAttribute("project", project);
    return "project/edit";
}

部分模板:

<script>
    var app = new Vue({
        el: '#app',
        data: {
            project: [(${project})]
        }
    });
</script>

Thymeleaf 开箱即用，我认为您只需要添加 th:inline="javascript" 。

http://www.thymeleaf.org/doc/tutorials/2.1/usingthymeleaf.html#script-inlining-javascript-and-dart

<script th:inline="javascript">
    var app = new Vue({
        el: '#app',
        data: {
            project: /*[[${project}]]*/ {}
        }
    });
</script>
