Question

我还是Java和Spring的新手。我目前正在开发和申请本地棒球联赛。我创建了两个统计保持模型。我想要做的是添加一名玩家然后指向一个表单以收集攻击性统计数据，然后向另一个表单收集投球统计数据（如果有的话）。但是，我遇到了405错误＆＃39; POST＆＃39;在提交攻击统计数据并被重定向到下一个以收集其余统计数据后不允许。流：添加播放器 - ＆gt;添加玩家进攻统计 - ＆gt;添加玩家投球统计

我考虑过将所有统计数据都包含在一个模型中，但如果我在视图中拥有相同数量的控制权，我有点不确定。

Answer 1

错误清楚地表明您尝试使用POST方法访问URL，但它没有METHOD TYPE + URL端点。（HTTP状态405表示不允许使用方法，因此存在端点，但方法不匹配）

你能检查浏览器网络选项卡（检查chrome / firefox / safari上的元素工作），看看它调用提交调用的URL是否失败。右键单击并选择Inspect。

网址终结点应为

POST：http://youripd:port/player/addoffense（如果您正在运行独立的可执行jar，例如spring boot）

或

POST：http://youripd:port/nameofwarfile/player/addoffense（如果你在像tomcat这样的容器中运行）

我想建议的另一件事是，让UI处理它应该发送到的下一个流程，而不是自动重定向/转发。这样每个表单都是独立的组件。

Spring Java - 请求方法＆＃39; POST＆＃39;不支持（方法不允许）
