Question

我最近将我的3.1.11应用程序升级到Grails 3.2.0应用程序并调用端点因为某些原因而开始因以下堆栈跟踪而失败：

ERROR org.grails.web.errors.GrailsExceptionResolver - StackOverflowError occurred when processing request: [GET] /api/application

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（期待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

经过一些调试和读取更改日志后，我们意识到在Grails 3.2.0中添加了文件views/object/_object.gson。删除该文件后，它开始正常工作。

Answer 1

这是解决方法确实要删除grails-app/views/object/_object.gson的错误。

由https://github.com/grails/grails-views/commit/27d2e546f9d723026fc4d0fb4c1384fa503d282c

解决

从3.1.11升级到3.2.0后的JSON视图错误
