【问题描述】：
我很长一段时间都在尝试将架构 play-spring-hibernate 但每次我尝试以下错误：
我经常尝试重置和重新配置。
是我缺少一些依赖吗？
此架构是否存在任何已报告的问题？
我正在使用的示例也留在播放站点中：
https://github.com/jamesward/play2bars/tree/java-spring
我必须修改项目的依赖才能运行。
但是当我总是提出请求时，当我调用 Form form = Form.form (Bar.class) .bindFromRequest() 方法时，它会生成发布的错误。

【问题讨论】：
-
你得到“引起：java.lang.IllegalArgumentException：类型不能为空”可能由“org.springframework.core.convert.TypeDescriptor.valueOf(TypeDescriptor.java:493)返回null”~ [spring-core-4.0.0.RELEASE.jar:4.0.0.RELEASE]" 你能把断点放在那里并检查这个空值是从哪里来的吗？ BTW 有 spring 4.1.1，也许也能解决这个问题。
-
我初始化了我的表单： public static Form
formServidorModel = Form.form(entities.ServidorModel.class);当我执行 Map map = new HashMap (); 时发生错误map.put("cpf", "cpf"); formServidorModel.bind(map).get(); // kill vm 大部分变量都是空的，但是在游戏框架手册中就像我展示的那样。我认为该框架没有正确初始化对象Form（我不知道是否因为弹簧而发生错误）您有什么想法吗？ -
首先更新到Spring 4.1.1。然后在此 IllegalArgumentException 出现的地方放置断点。我在 Spring 源代码中看到，该类型作为参数传递给 Spring 的方法并且丢失/为空。检查它来自哪里。也许这会让你知道为什么它是空的。
