JSON 从 3.1.11 升级到 3.2.0 后查看错误
JSON view error after upgrading from 3.1.11 to 3.2.0
我最近将我的 3.1.11 应用程序升级到 Grails 3.2.0 应用程序，由于某些原因，对端点的调用开始失败，堆栈跟踪如下：

这是我使用的简单控制器：
class ApplicationController {
static allowedFormats = ["json"]
def index() {
Map result = [username: "foo"]
respond(result)
}
}
点击 /application/index 端点（预期 JSON）请求在 3.1.11 上正常工作，但在升级到 3.2.0 后开始失败
经过一些调试和阅读更改日志，我们意识到在 Grails 3.2.0 中添加了一个文件 views/object/_object.gson。删除该文件后，它开始正常工作。
这是一个错误，解决方法确实是删除 grails-app/views/object/_object.gson。
