Spring MVC< form:errors/>标签找不到错误消息 [英] Spring MVC <form:errors/> tag doesn't find error messages
问题描述
我与编写JSP文件的前端开发人员一起工作.我们有一个可以正常工作的表单，除了似乎无法在Spring的<form:errors/>标记中显示验证/绑定/处理错误之外.
I work with a front-end developer who writes JSP files. We have a form that is working correctly, except validation/binding/processing errors can't seem to be displayed with Spring's <form:errors/> tag.
我已经确认正在设置错误，并且显然是错误的正确路径.假定<form:errors path="*" />应该呈现所有路径，而不管路径如何，但是它什么也没显示.
I've confirmed that the error is being set, and what is apparently the correct path for the errors. Supposedly <form:errors path="*" /> should render them all, regardless of path, but it shows nothing.
我需要进入标签库源代码来推断出什么问题吗?
Do I need to get into the tag library source to deduce what's going wrong?
推荐答案
简单答案:< form:errors/>必须位于< form:form/>元素内才能绑定到模型的"command"对象
Simple answer: <form:errors/> must be within a <form:form/> element in order to bind to the model's "command" object.
